KI am Bau: Zwischen Digitalisierung und Automatisierung
Künstliche Intelligenz verändert zunehmend auch die Bauwirtschaft. Ein aktueller Fachbeitrag des Süddeutschen Holzbau Kongresses SHK 2025 zeigt, welche Rolle KI künftig im Holzbau spielen könnte.
Der Beitrag „KI im Bau – Fluch oder Segen?“ stammt von Prof. Dr.-Ing. Jörn Plönnigs von der Universität Rostock – Professur für Künstliche Intelligenz für nachhaltiges Bauen.
Besonders interessant: Der Holzbau wird darin ausdrücklich als möglicher Vorreiter für digitalisierte und automatisierte Bauprozesse beschrieben. Gründe dafür sind:
- hohe Vorfertigung,
- modulare Bauweisen,
- CNC-Fertigung,
- digitale Planung
- und automatisierte Produktionsprozesse.
Der Beitrag beschreibt außerdem sogenannte „Building Foundation Models“. Diese spezialisierten KI-Systeme könnten künftig:
- BIM-Daten analysieren,
- technische Dokumentationen auswerten,
- Baufortschritte erkennen,
- CNC-Daten generieren
- oder Wartungs- und Rückbauprozesse unterstützen.
Gleichzeitig werden auch die aktuellen Grenzen von KI klar angesprochen:
- fehlendes technisches Verständnis,
- fehlerhafte Antworten,
- mangelndes räumliches Denken
- und die Notwendigkeit fachlicher Kontrolle durch Menschen.
Der Fachbeitrag zeigt eindrucksvoll, dass Themen wie Robotik, digitale Fertigung, Vorfertigung und BIM künftig noch stärker zusammenwachsen werden – insbesondere im modernen Holzbau.

Webinar:
Neue EU-Vorgaben verändern den Holzbau
Am Mittwoch, 20. Mai 2026, von 11:00 bis 11:45 Uhr informiert Metsä Wood im Rahmen eines aktuellen Webinars über wichtige europäische Entwicklungen und deren Auswirkungen auf die Bau- und Holzbranche.
Im Mittelpunkt stehen unter anderem folgende Themen:
- neue CO₂-Grenzwerte für Gebäude über den gesamten Lebenszyklus
- Kreislauffähigkeit und Rückbaubarkeit von Bauwerken
- Anforderungen an die Herkunfts- und Lieferkettendokumentation von Holzprodukten
- nachhaltige Stadt- und Gebäudeentwicklung im Rahmen des „New European Bauhaus“
- europäische Strategien für leistbaren Wohnbau
Besonders relevant wird dabei die neue europäische Gebäuderichtlinie (EPBD), die künftig stärkere Anforderungen an die CO₂-Bilanz von Neubauten stellt. Auch Themen wie digitale Materialdaten, Environmental Product Declarations (EPDs) und die Wiederverwendbarkeit von Bauteilen gewinnen zunehmend an Bedeutung.
Für den modernen Holzbau ergeben sich daraus nicht nur neue Anforderungen, sondern auch große Chancen. Nachhaltige, ressourcenschonende und kreislauffähige Bauweisen rücken stärker in den Mittelpunkt europäischer Baupolitik.
Gerade im Bereich des modularen Holzbaus, der Vorfertigung und der präzisen digitalen Fertigung zeigt sich, wie wichtig eine frühzeitige Auseinandersetzung mit diesen Entwicklungen ist.
Brandschutz im Industriebau aus Holz
Neue Veröffentlichung zeigt: Holz kann mehr als gedacht
Mit der aktuellen Publikation zum Thema Brandschutz bei Industriebauten in Holzbauweise liegt eine umfassende und praxisnahe Aufarbeitung vor.
Die zentrale Erkenntnis:
Holzbau ist im Industriebau längst nicht mehr die Ausnahme – sondern eine technisch und regulatorisch tragfähige Lösung.
Warum diese Veröffentlichung relevant ist
Industriebauten standen lange im Spannungsfeld zwischen
- hohen Brandschutzanforderungen
- und wirtschaftlicher Bauweise
Die neue Auslegung zeigt:
Beides ist vereinbar – wenn Planung und System richtig gedacht werden.
👉 Holzbau wird als Bauweise ausdrücklich berücksichtigt
👉 Anforderungen sind klar definiert und nachvollziehbar
👉 Neue Nachweisverfahren schaffen Sicherheit in der Planung
Die zentralen Inhalte im Überblick
1. Klare Systematik für Industriebauten
Die Publikation zeigt, wie Industriebauten strukturiert bewertet werden:
- Einteilung nach Nutzung und Risiko
- Anwendung der Industriebau-Richtlinie
- Differenzierung zwischen Hallen, Büroanteilen und Mischformen
👉 Entscheidend ist nicht der Baustoff – sondern die Nutzung und das Risiko.
2. Zwei Wege zum Brandschutznachweis
Tabellenverfahren
- standardisiert
- robust
- schnell anwendbar
Ingenieurmäßiger Nachweis
- basiert auf realen Brandlasten
- ermöglicht größere Einheiten
- bietet mehr Freiheit in der Konstruktion
👉 Genau hier liegt das Potenzial für den modernen Holzbau.
3. Holztragwerke im Industriebau
Ein wesentlicher Punkt der Veröffentlichung:
👉 Holztragwerke sind im Industriebau zulässig – unter klaren Randbedingungen
- Einsatz in bis zu zwei Geschossen
- robuste Konstruktionen ohne klassischen Feuerwiderstandsnachweis möglich
- Mindestquerschnitte sichern das Tragverhalten im Brandfall
👉 Holz verhält sich im Brandfall berechenbar – das ist der Schlüssel.
4. Weiterentwicklung der Richtlinien
Die aktuelle Richtlinie schafft neue Spielräume:
- größere Brandabschnitte möglich
- Integration von Holztragwerken vereinfacht
- Berücksichtigung technischer Anlagen wie Löschsysteme
👉 Planungsspielraum entsteht dort, wo Systemverständnis vorhanden ist.
5. Praxis zeigt die Umsetzbarkeit
Ein Beispiel aus der Veröffentlichung:
- Produktionshalle mit rund 14.000 m²
- Tragwerk vollständig aus Holz
- Brandschutz über ingenieurmäßigen Nachweis geführt
👉 Ergebnis:
Die Anforderungen konnten wirtschaftlich und regelkonform erfüllt werden.
Einordnung für die Praxis
Die Veröffentlichung macht eines deutlich:
👉 Der Baustoff ist nicht mehr die Hürde
👉 Die Planung ist der entscheidende Faktor
Wer versteht:
- Lastannahmen
- Nutzungsszenarien
- konstruktive Details
- und Fertigung
kann Industriebauten in Holz effizient und sicher realisieren.
Einordnung aus Leidorf-Sicht
Genau hier liegt der Hebel:
👉 Industriebau wird nicht auf der Baustelle entschieden – sondern in der Produktion
- präzise Vorfertigung
- durchdachte Konstruktion
- reproduzierbare Qualität
ermöglichen es, die Anforderungen aus dem Brandschutz sicher umzusetzen.
Holzbau funktioniert dort am besten, wo Planung und Fertigung zusammen gedacht werden.
Fazit
Diese Veröffentlichung markiert einen wichtigen Schritt:
- Holzbau im Industriebau ist technisch etabliert
- Brandschutz ist planbar
- große Spannweiten und Flächen sind realisierbar
👉 Die Frage ist nicht mehr, ob Holz im Industriebau funktioniert
👉 sondern wie konsequent man das System nutzt
München startet Pilotförderung für zirkuläres Bauen
Die Landeshauptstadt München setzt ein starkes Zeichen für die Zukunft der Bauwirtschaft:
Ab September 2026 werden erstmals gezielt Pilotprojekte im zirkulären Bauen promoted.
Mit einer Förderquote von 20–60 % und einer maximalen Unterstützung von bis zu 400.000 € pro Projekt richtet sich das Programm an Bauherren und Planer, die neue Wege in Richtung Kreislaufwirtschaft gehen möchten.
Warum zirkuläres Bauen jetzt im Fokus steht
Die Bauwirtschaft gehört zu den ressourcenintensivsten Branchen überhaupt. Gleichzeitig steigen die Anforderungen an CO₂-Reduktion, Rückbaubarkeit und Materialeffizienz.
Zirkuläres Bauen setzt genau hier an:
Materialien werden im Kreislauf geführt
Gebäude werden als Rohstofflager gedacht
Konstruktionen sind rückbaubar statt dauerhaft verbunden
Damit verändert sich nicht nur die Bauweise – sondern das gesamte System dahinter.
Was konkret gefördert wird
Die Pilotförderung richtet sich an Projekte, die innovative Ansätze im Bauwesen praktisch umsetzen, insbesondere:
sortenreine Konstruktionen
lösbare Verbindungen
wiederverwendbare Bauteile
neue Material- und Systemlösungen
Wichtig dabei:
Der Baubeginn darf erst nach der Antragsprüfung erfolgen und das Projekt muss sich im Stadtgebiet München befinden.
Von der Idee zur Umsetzung: Wo Leidorf ansetzt
Viele der geforderten Kriterien sind heute bereits technisch umsetzbar – wenn Planung und Produktion zusammengedacht werden.
Genau hier setzt Leidorf an:
Modulares Bauen
→ Gebäude werden in wiederverwendbaren Einheiten gedachtIndustrielle Vorfertigung
→ Präzision im Werk statt Improvisation auf der BaustelleRoboter-CNC-Abbund
→ exakte, reproduzierbare Verbindungen für lösbare KonstruktionenRückbau mit System
→ Bauteile werden nicht entsorgt, sondern gezielt wiederverwendetWeiterverwendung von Holzbauteilen
→ Konstruktionen werden von Anfang an für den zweiten Lebenszyklus mitgedacht
Damit entsteht ein durchgängiger Ansatz:
Vom Entwurf bis zum Rückbau – alles ist auf Kreislauf ausgelegt.
Ein Signal für die gesamte Branche
Bemerkenswert ist der Zeitpunkt:
In einer Phase wirtschaftlicher Unsicherheit investiert München bewusst in neue Baukonzepte.
Die Pilotprojekte dienen nicht nur als Einzelmaßnahmen, sondern als Grundlage für zukünftige Standards im Bauwesen.
Infoveranstaltung
Eine erste Online-Infoveranstaltung findet statt am:
23. März um 12:00 Uhr
Hier erhalten Interessierte einen Überblick über die Förderbedingungen und können prüfen, ob ihr Projekt geeignet ist.
Contact:
pilotfoerderung-zirkulaeres-bauen@muenchen.de
Fazit
Die Münchner Pilotförderung ist mehr als ein finanzieller Anreiz.
Sie ist ein klarer Schritt in Richtung eines neuen Bauverständnisses:
Weg vom Verbrauch – hin zum Kreislauf.
Und genau hier entscheidet sich, wer die Bauweise von morgen mitgestaltet.

Neuer Leitfaden für Gewerke-Schnittstellen im Holzhochbau
Holzbau funktioniert anders.
Und genau deshalb braucht er eine andere Planung.
Mit dem neuen „Leitfaden für Gewerke-Schnittstellen im Holzhochbau“ (Holzforschung Austria, 12/2025) liegt nun eine strukturierte und praxisnahe Orientierungshilfe für alle Beteiligten im Holzhochbau vor.
Erarbeitet wurde der Leitfaden vom Bereich Holzhausbau der Holzforschung Austria gemeinsam mit KOPPELHUBER2 und Partner im Auftrag der Holzbauplattform im Fachverband der Holzindustrie Österreichs.
Warum das Thema so wichtig ist
Im Holzhochbau treffen zahlreiche Gewerke aufeinander:
Holzbau, Haustechnik, Fassadenbau, Trockenbau, Brandschutz, Statik, Logistik, Montage.
Wer hier nicht frühzeitig koordiniert, riskiert:
Verzögerungen im Bauablauf
Nacharbeiten auf der Baustelle
unnötige Mehrkosten
Qualitätsverluste
Gerade im CLT- und Hybridbau entscheidet der richtige Planungszeitpunkt über Effizienz und Wirtschaftlichkeit.
Was der Leitfaden leistet
Der Leitfaden bietet:
eine strukturierte Übersicht zentraler Schnittstellen
klare Definitionen von Verantwortlichkeiten
praxisnahe Empfehlungen für Planung und Ausführung
Orientierung zu Normen und Prozessschritten
konkrete Detailpunkte zur Koordination zwischen Gewerken
Ziel ist eine interdisziplinäre Planung, die Holzbau sicherer, effizienter und qualitativ hochwertiger macht – ohne zusätzliche Kostenanforderungen.
Unsere Einordnung bei Leidorf
Als Partner für CLT, PuraTimber, Kerto, LVL, Modulbau und CLT-Logistik erleben wir täglich:
Nicht das Holz ist die Herausforderung –
sondern die Abstimmung zwischen Planung, Vorfertigung und Montage.
Frühzeitige Schnittstellenklärung bedeutet:
saubere Vorfertigung
weniger Improvisation auf der Baustelle
planbare Logistik
klare Verantwortlichkeiten
Holzbau ist ein Präzisionsprozess. Und Präzision beginnt in der Planung.

Zirkuläres Bauen: Vom Trend zur Erwartung
Zirkuläres Bauen ist längst kein Zukunftsszenario mehr.
Regulatorische Anforderungen, ESG-Kriterien, EU-Taxonomie und steigende Materialpreise verändern die Spielregeln im Bauwesen grundlegend.
Gefragt sind nicht nur energieeffiziente Gebäude –
gefragt sind rückbaubare, dokumentierte und wiederverwendbare Konstruktionen.
Zirkularität beginnt bei der Konstruktion
Kreislaufwirtschaft entscheidet sich nicht beim Abbruch, sondern beim Entwurf.
Design for disassembly – Bauteile so planen, dass sie demontierbar bleiben
Materialtransparenz – klare Dokumentation von Materialien und Verbindungen
Struktur statt Verbund – Konstruktionen, die sortenrein trennbar sind
Holzbau bietet hier enorme Potenziale.
Insbesondere konstruktive Holzsysteme wie CLT ermöglichen präzise Vorfertigung, klare Materialstrukturen und eine gute Rückbaubarkeit – vorausgesetzt, sie werden konsequent zirkulär gedacht.
Bauteile als Wertstofflager
Ein Gebäude ist kein Endprodukt.
Es ist ein temporäres Materiallager.
Wenn Bauteile identifizierbar, lösbar und wieder einsetzbar sind, entsteht echter Mehrwert – ökologisch wie wirtschaftlich.
Rohstoffe bleiben im Kreislauf, graue Energie wird erhalten, und der Ressourcenverbrauch sinkt.
Unser Ansatz bei Leidorf
Bei Leidorf denken wir Holzbau als strukturiertes System:
CNC-präzise gefertigte Bauteile
klare Konstruktionen
Fokus auf demontierbare Lösungen
Integration in digitale Planungsprozesse
Zirkuläres Bauen ist für uns keine Zusatzoption, sondern eine konstruktive Haltung.
Die Bauwirtschaft steht vor einem Paradigmenwechsel.
Wer heute rückbaubar plant, baut morgen resilient.
500.000 € Förderung für Bauteil-Wiederverwendung in Baden-Württemberg
Mit einem neuen Förderprogramm setzt das Land Baden-Württemberg ein starkes Signal für zirkuläres Bauen:
Insgesamt 500.000 Euro stehen für Modellprojekte zur Wieder- und Weiterverwendung von Bauteilen zur Verfügung.
Ziel der Förderung ist es, lineare Bauprozesse aufzubrechen und die Wiederverwendung tragender und nicht tragender Bauteile in die Praxis zu bringen. Unterstützt wird dabei genau jener organisatorische und technische Mehraufwand, der für eine hochwertige Bauteilwiederverwendung notwendig ist – etwa Rückbau, Prüfung, Aufbereitung und Wiedereinbau.
What is promoted?
Die Förderquote ist nach Bauteilkategorien gestaffelt:
80 % Förderung für tragende Bauteile
z. B. Stahl-, Holz- oder Betonbauteile60 % Förderung für Bauteile der Gebäudehülle
z. B. Fassaden- oder Außenwandelemente40 % Förderung für Innenausbau-Bauteile
z. B. Fenster, Trennwände oder Verkleidungen
Gefördert werden reale Bauvorhaben in Baden-Württemberg, die Wiederverwendung nicht nur theoretisch planen, sondern praktisch umsetzen. Ziel sind sichtbare Referenzprojekte, die zeigen, dass Bauteil-ReUse technisch machbar, wirtschaftlich sinnvoll und planerisch integrierbar ist.
Einreichfristen
Die Projekteinreichung erfolgt in zwei Runden:
until 31. März 2026
until 30. Juni 2026
Bedeutung für den Holzbau und CLT
Gerade im Holzbau – etwa bei CLT-Bauteilen, Treppen, Deckenelementen oder tragenden Wandbauteilen – liegt ein großes Potenzial für Wiederverwendung. Voraussetzung dafür sind klare Konstruktionen, dokumentierte Bauteile und eine Planung, die Rückbau und Weiterverwendung von Anfang an mitdenkt.
Die Förderung adressiert damit genau jene Punkte, die im Baualltag oft als Hürde gesehen werden – und schafft einen finanziellen Rahmen, um zirkuläre Lösungen erstmals breiter umzusetzen.
Fazit
Die Förderung aus Baden-Württemberg ist ein wichtiger Schritt, um zirkuläres Bauen vom Einzelprojekt in die Breite zu bringen.
Für Bauherren, Planer und ausführende Unternehmen eröffnet sich damit die Möglichkeit, Wiederverwendung strukturiert, gefördert und praxisnah umzusetzen.
Heilbronn als Reallabor: Warum Holzbau und KI hier zusammenfinden
Heilbronn entwickelt sich derzeit zu einem der spannendsten Standorte für Künstliche Intelligenz in Deutschland. Mit dem Innovationspark Künstliche Intelligenz (IPAI), neuen Forschungsbauten, Rechenzentren und universitären Einrichtungen entsteht ein Ökosystem, das weit über klassische IT-Infrastruktur hinausgeht.
Was dabei oft übersehen wird:
Die baulichen Strukturen dieser neuen KI-Landschaft stehen vor völlig neuen Anforderungen – und genau hier rückt der moderne Holz- und Hybridbau ins Zentrum der Diskussion.
Ein Standort mit strategischer Tiefe
Heilbronn ist kein Zufallsprodukt. Der Ausbau des Bildungs- und Forschungsstandorts wurde über viele Jahre konsequent vorbereitet. Der Campus Heilbronn mit mehreren Hochschulen, Forschungseinrichtungen und Innovationszentren bildet heute das Rückgrat dieser Entwicklung.
Unabhängig von einzelnen Projekten ist klar:
Der Standort profitiert von einer langfristigen Strategie, in der Forschung, Digitalisierung und wirtschaftliche Anwendung eng miteinander verzahnt sind. KI wird hier nicht isoliert gedacht, sondern als Teil einer realen, gebauten Infrastruktur.
Neue Anforderungen an KI-Bauten
KI-Zentren, Forschungsgebäude und Recheninfrastruktur stellen andere Anforderungen als klassische Büro- oder Gewerbebauten:
hohe technische Lasten und flexible Grundrisse
schnelle Realisierungszeiten
modulare Erweiterbarkeit
hohe Anforderungen an Nachhaltigkeit und CO₂-Bilanz
zunehmende politische und gesellschaftliche Erwartung an ressourcenschonendes Bauen
Gerade Rechenzentren und forschungsnahe Gebäude stehen unter Druck, Energieeffizienz und graue Emissionen deutlich zu reduzieren. Beton allein wird diesen Anspruch langfristig nicht erfüllen.
Holzbau als logische Antwort
Der moderne Holzbau – insbesondere in Form von CLT-, Hybrid- und modularen Systemen – bietet genau jene Eigenschaften, die für KI-Infrastruktur entscheidend sind:
CO₂-Speicherung statt Emissionen
hohe Vorfertigung und kurze Bauzeiten
präzise planbare, industrielle Qualität
gute Kombinierbarkeit mit Stahl und Beton dort, wo es technisch notwendig ist
Rückbaubarkeit und Anpassungsfähigkeit für sich schnell wandelnde Nutzungen
Damit wird Holzbau vom „ökologischen Zusatzargument“ zu einem strategischen Baustoff für High-Tech-Infrastruktur.
Heilbronn als Blaupause
Der Innovationspark KI in Heilbronn zeigt exemplarisch, wohin die Entwicklung gehen kann:
Nicht einzelne Gebäude stehen im Fokus, sondern ganze Quartiere, die Forschung, Anwendung und Wachstum ermöglichen.
Für den Holzbau bedeutet das:
größere Spannweiten
mehrgeschossige, technisch hochgerüstete Gebäude
serielle und modulare Konzepte
industrielle Planungstiefe
Genau in solchen Projekten entscheidet sich, ob Holzbau den Schritt vom nachhaltigen Nischenprodukt zur tragenden Struktur der digitalen Zukunft schafft.
Leidorf: Holzbau für die nächste Infrastruktur-Generation
Als Unternehmen an der Schnittstelle von Holztechnik, industrieller Vorfertigung und digitalem Planen sieht Leidorf in Projekten wie Heilbronn ein klares Signal:
Die Zukunft der KI braucht nicht nur Rechenleistung, sondern auch intelligente, nachhaltige Bauweisen.
Holz ist dabei kein Widerspruch zur High-Tech-Welt – sondern ihre konsequente bauliche Weiterentwicklung.
Neues Holz-Potenzial für München: Paketpost-Quartier und Aufhebung der 100-Meter-Grenze
Mit der jüngsten Entscheidung, die bisherige Höhenbegrenzung von 100 Metern für Gebäude in München aufzuheben, eröffnet sich ein neues Kapitel für die Stadtentwicklung – insbesondere für nachhaltige und innovative Bauweisen. Ein Projekt, das diese Entwicklung exemplarisch widerspiegelt, ist das geplante Paketpost-Quartier im Münchner Westen.
Transformation eines Wahrzeichens
Im Mittelpunkt des Areals steht die denkmalgeschützte Paketposthalle aus den 1960er-Jahren, entworfen vom Münchner Architekten Sepp Ruf – einem der prägenden Vertreter der deutschen Nachkriegsmoderne. Die Halle gilt bis heute als ingenieurtechnisches Meisterwerk: Mit ihrer freitragenden Dachkonstruktion und einer Spannweite von über 146 Metern war sie zur Bauzeit eine internationale Sensation und steht exemplarisch für Rufs klare, konstruktive und zugleich gesellschaftlich gedachte Architektur.
Der Masterplan des renommierten Architekturbüros Herzog & de Meuron sieht vor, die Halle als öffentlichen, überdachten Stadtraum zu erhalten und neu zu beleben. Kultur, Begegnung und urbane Nutzung sollen hier zusammenkommen und das Quartier prägen.
Rund um die Halle entsteht ein gemischt genutztes Stadtviertel mit Wohnraum, Arbeitsplätzen, öffentlichen Einrichtungen und großzügigen Freiflächen. Geplant ist ein autoarmes Quartier mit kurzen Wegen, hoher Aufenthaltsqualität und zeitgemäßen Mobilitätskonzepten.
Neue Höhen – neue Möglichkeiten
Besonders aufmerksamkeitsstark sind die zwei geplanten Hochpunkte mit einer Höhe von rund 155 Metern. Sie wären deutlich höher als alles bisher Realisierte in München und wären ohne die Aufhebung der 100-Meter-Grenze nicht denkbar gewesen. Die Entscheidung markiert einen Paradigmenwechsel in der Münchner Stadtplanung und eröffnet neue Spielräume für vertikale, flächeneffiziente Stadtentwicklung.
Relevanz für den modernen Holzbau
Auch wenn der aktuelle Entwurf kein reines Holzhochhaus vorsieht, ist die Signalwirkung enorm. Höhere Gebäude bedeuten künftig auch:
mehr Potenzial für Holz-Hybrid-Konstruktionen
bessere Rahmenbedingungen für CO₂-reduzierte Bauweisen
neue Anwendungsfelder für industriell vorgefertigte Holzbausysteme
nachhaltige Nachverdichtung in urbanen Lagen
Gerade im Kontext von Klimazielen, Ressourceneffizienz und Kreislaufwirtschaft bietet der Holzbau entscheidende Vorteile. Projekte wie das Paketpost-Quartier zeigen, dass Stadtentwicklung, Dichte und Nachhaltigkeit kein Widerspruch sein müssen.
Impuls für die Zukunft
Das Paketpost-Quartier wird intensiv diskutiert – zwischen Stadtbildschutz, Wohnraumbedarf und Innovationsanspruch. Unabhängig vom finalen Ausgang steht fest: Mit der Aufhebung der Höhenbegrenzung hat München eine neue planerische Freiheit gewonnen. Für den modernen Holzbau und hybride Bauweisen eröffnen sich damit neue Perspektiven – auch für komplexe, innerstädtische Großprojekte.
Für Leidorf ist diese Entwicklung ein wichtiges Signal: Die Zukunft des urbanen Bauens wird höher, dichter – und nachhaltiger.

New insights into wall reinforcement - Kerto LVL impresses with stability and precision
The current issue of Timber construction statics up to date (05/2025) shows:
When bracing timber construction walls, it is worth taking a look at innovative materials. In addition to classic boards such as OSB, plywood or gypsum fibre Kerto LVL are increasingly coming into focus - especially where high rigidity, dimensional accuracy and load-bearing capacity are required.
Why Kerto LVL?
Kerto LVL (Laminated Veneer Lumber) is made from several layers of Nordic spruce veneers and impresses with its
Exceptional dimensional stability - No warping or swelling with changing humidity
High shear stiffness and strength - Ideal for bracing wall panels
Precise CNC machining - For precise fits and tight joints
Low dead weight with high load-bearing capacity
Predictable fire behaviour - Predictable fire resistance due to defined burn-off rate
This makes Kerto LVL not only an alternative, but also a Technically superior solution for load-bearing and bracing wall systems - especially in the multi-storey timber construction.
Focus on multilayer systems
The specialised publication examines the Combination of several panel layers (e.g. OSB + gypsum fibre or LVL + gypsum plasterboard) and shows how optimised shear transfer between the layers can be achieved. Significantly higher rigidity can be achieved.
Kerto LVL contributes to this, Reduce overall height and material usage, without compromising structural safety.
The complete PDF „Wall panels with multiple panels“ from Timber construction statics current 05/2025 is now available here

New handout: Lot bundling for timber construction contracts
The Agency for Renewable Resources (FNR) has published a new Guidance on lot bundling for timber construction contracts a practical guide for public construction projects.
The aim of the publication is to, public clients in the planning and tendering of timber construction projects. Sustainable timber construction projects often fail due to small-scale tenders that make innovative construction methods more difficult. The handout shows, How to bundle and efficiently award contracts in a legally compliant manner, without restricting competition.
Special attention is paid to:
the Optimisation of procurement processes,
the Utilisation of existing legal framework,
and the Promotion of timber construction as a climate-friendly building method in the public sector.
The publication was published as part of the Charter for wood 2.0 and the Timber construction initiative through the Federal Ministry of Food and Agriculture (BMEL) promoted.
Life cycle assessment in practice - guidelines for architects, planners & building owners
The Hesse Chamber of Architects and Town Planners has been involved in the Timber construction campaign Hesse 2025 has published a new guide:
„Life cycle assessment in practice - guidelines for more climate-friendly planning & building“.
Why this guide is important
The building sector causes around 40 % of CO₂ emissions and 90 % of raw material consumption in Germany. In order to achieve the climate targets, the focus is therefore shifting to a holistic view of the entire life cycle of buildings - from production and operation through to dismantling.
Contents of the guide
Practical introduction to life cycle assessment (LCA)
Tools and methods for assessing the environmental impact of construction projects
Comparative examples between conventional and sustainable construction methods
Recommendations for architects, planners and clients for implementation in early project phases
Wood as the key to climate-friendly construction
Particular emphasis is placed on the role of the Timber construction:
renewable, regionally available raw material
CO₂ storage with a contribution to the circular economy
enables short construction times and sustainable building concepts
Our conclusion with Leidorf
In future, life cycle assessment will be a central tool in every construction project - just as important as cost planning. It makes the Transparent climate impact of building materials and supports well-founded decisions in favour of sustainable construction methods.
Reuse of timber and steel components - results of a research project
The Karlsruhe Institute of Technology (KIT) and the Technical University of Munich (TUM) completed an extensive research project at the end of 2024: „Preparation for the reuse of certain timber and steel construction products“, funded by the Baden-Württemberg Ministry for Regional Development and Housing.
Aim of the project
The construction sector generates around half of the world's waste. Until now, load-bearing timber and steel components have mostly been recycled or disposed of after dismantling. The aim of the project was to develop processes and guidelines to ensure that these components can be safely recycled in the future. reused and thus save resources, energy and CO₂.
Central results
Inventory analysis: Methods for determining the potential of components before they are dismantled.
Selective dismantling: Careful dismantling is crucial in order to recover load-bearing elements undamaged.
Testing and classification procedures: Development of practical approaches for testing the quality and load-bearing capacity of steel and timber components.
Preparation: Recommendations for cleaning, processing and renewing surfaces.
Building law: The first way to prove usability is via approval in individual cases (ZiE) or project-related type approval (vBG).
Significance for practice
With the developed Guide to reuse is now available as a practice-orientated tool that provides building owners, planners and contractors with concrete assistance - from as-built analysis to dimensioning. This represents an important step towards a functioning Circular economy in the construction industry made.
Outlook
There are still many unanswered questions - such as the standardisation of test procedures, the creation of material databases and the adaptation of building regulations. However, one thing is clear: the reuse of timber and steel components is technically feasible and can make a significant contribution to conserving resources in the future.
How safe is timber construction in the event of fire?
New research results provide clear answers:
Studies by the Agency for Renewable Resources (FNR) show that Timber buildings are just as safe as conventional construction methods when built correctly and with a well thought-out fire protection concept.
This disproves a frequently cited prejudice: Timber construction stands for sustainability and climate protection - and is also convincing in terms of safety.
At Leidorf, we see these results as confirmation:
Ecological - Wood is a renewable raw material with an excellent carbon footprint.
Safe - Fire protection in timber construction is plannable and reliable.
Pioneering - Sustainable construction methods are an essential key to the building turnaround.
In our projects, we combine innovative production technologies with modern timber construction. This results in buildings that Ecological, safe and sustainable are.

Changing values in the mountains: guide for sustainable mountain huts published
How can mountain huts in the Alps be planned and built in a more sustainable, resource-saving and future-proof way?
The new Guide „Changing values on the mountain“, published by the German Alpine Club (DAV), provides answers - and sets clear impulses for the entire construction industry.
Sustainability starts with planning
The guide shows in a practical and well-founded way how alpine infrastructure can be optimised in terms of Sufficiency, Efficiency and Consistency can be rethought. The focus is on strategies for reducing grey emissions, using renewable raw materials and designing recyclable construction methods. The findings are based, among other things, on the „Hochlandhütte“ pilot project and were developed by an interdisciplinary team of experts.

As a specialist for Precise woodworking, modular timber construction and Demountable constructions sees itself Leidorf The company has a particular responsibility to help shape these new standards.
Our CNC technologies make it possible to realise resource-saving and durable solutions with a high level of craftsmanship - even under the challenging conditions of the Alpine region.
„Sustainability is not achieved through compensation, but through well thought-out planning and intelligent design.“
- Alexander Leidorf
Sustainable building: From the mountain to the valley
The approaches in the guidelines do not only apply to refuges. They are transferable to many construction tasks, where robustness, circular thinking and material efficiency take centre stage - even in the valley. Leidorf is supporting this change in values with experience, technology and a passion for wood as a material.
Contact us You us, if you want to plan a sustainable and recyclable project. We are happy to support you from the initial idea through to realisation.
New guide to the reuse of load-bearing components published
An important step towards greater sustainability in the construction industry
In May 2025, a practical guideline was published that has been recognised throughout Germany. Reuse of load-bearing steel and timber components published. Created by Ministry for Regional Development and Housing Baden-Württemberg in co-operation with the Karlsruhe Institute of Technology (KIT) and the Technical University of Munich, this guide sets new standards for circular construction in practice.
As a company that specialises in modern wood processing, deconstruction and resource-saving construction concepts, we welcome you to Leidorf expressly recognises this important step.
What is the guide about?
The guide offers a structured approach to reusing entire load-bearing components - such as those made of steel or softwood - and is aimed at
Planners and specialist planners
Test engineers and experts
Authorities and construction companies
Owners of existing buildings
It provides a practical description of how used components can be systematically recorded, tested, processed and safely reused in new construction projects.
Contents of the guide at a glance
Inventory analysisHow do I recognise reusable components?
DeconstructionSelective and component-friendly dismantling by specialised companies
Testing & preparationProof of physical and mechanical properties, decontamination, sorting
DimensioningAccording to current standards, taking into account conservative assumptions
Material-specific appendicesDetailed testing and design specifications for steel and timber components
Why is this relevant?
A large proportion of the CO₂ emissions and resource consumption in the construction industry arises in the manufacture of load-bearing structures. These loads can be significantly reduced by reusing existing components.
At the same time, the guide creates legal certainty for building owners and planners by providing a sound basis for Approvals in individual cases (ZiE) and Project-related type approvals (vBg) offers.

New study: Nature-based materials as the key to a climate-neutral building transition
Bauhaus Earth and the Natural Building Lab of the TU Berlin have been commissioned by Built by Nature published a comprehensive study:
„Nature-based building in Germany - paths to climate-neutral construction“.
The core message:
The building sector in Germany is falling well short of its climate targets - even though climate-friendly alternatives have long been available.
Nature-based materials: focus on wood, hemp, clay & co.
The study impressively demonstrates the potential Bio-based building materials offer:
They cause Significantly lower emissions as concrete or steel
You can Store carbon permanently
You promote Regional value creation and Conservation of resources
Above all Wood already plays a central role today - but materials such as Hemp, clay or straw urgently need to be brought out of their niche.
What is missing?
Despite technological maturity, the following factors inhibit the use of nature-based materials:
Missing Binding CO₂ limit values for new buildings
Support programmes usually only take into account the energy consumption during operation, not the choice of materials
Lengthy authorisation procedures, especially in multi-storey timber construction
Gaps in knowledge for planners, authorities and building owners
Our position at Leidorf
We are convinced that the construction turnaround will only succeed if we Digital building, Modular constructions and Renewable raw materials think together.
As Leidorf GmbH we combine High-tech timber construction, Robot-assisted production and Nature-based materials - and thus make an active contribution to the transformation of construction.

Building acoustics in hybrid construction: new findings for better sound insulation
Research results confirm: Hybrid constructions made of wood and concrete also impress acoustically
With the growing demand for sustainable living space Hybrid construction methods the focus - especially the combination of Wooden walls with reinforced concrete ceilings. In a current research project involving the Stuttgart University of Applied Sciences, the acoustic behaviour of such constructions comprehensively analysed.
Excellent air and impact sound insulation with a sophisticated design
The study shows: Hybrid constructions offer Excellent acoustic properties, if they are consistently planned and executed. This is particularly positive:
High airborne sound insulation through double-shell partition walls with facing constructions
Excellent impact sound insulation due to floating screed and elastic impact sound insulation
Reduced flank transmission with suitable detailing (separating joints, joints, decoupling)
Even in the case of multi-storey residential buildings with high sound insulation requirements Comfort values that are far above the minimum requirements of DIN 4109.
New calculation models for practical use
As no standardised calculation methods for hybrid buildings are yet available, the study suggests Specific prediction models for airborne and impact sound based on real construction measurements. These models create Planning security and help, Refurbishment costs or overdimensioning to avoid.
Our assessment at Leidorf
As a specialist for modular timber construction and CNC-supported production we see hybrid constructions as an important building block for the future. The new study confirms that Climate-friendly construction and high acoustic quality are not a contradiction in terms are.

How do simple, monolithic construction methods perform in everyday life? This question was at the centre of an unusual long-term experiment in Bad Aibling. Three formally identical apartment blocks - one made of wood, one made of brick and one made of infra-lightweight concrete - were scientifically monitored over a period of two years. The results of the recently published report „Simple construction 3 - measurement, validation, feedback“ provide exciting insights for the future of construction.
Simple materials - great effect
The project shows impressively: Simplicity can be more efficient than high-tech. The timber house achieved the best insulation value with a U-value of 0.22 W/m²K - exactly as in the laboratory, and without any additional insulation or vapour barrier. The concrete house scored points with its thermal inertia, which effectively reduces overheating in summer. The brick building, on the other hand, fell short of expectations - both in terms of insulation value and recyclability.
User behaviour counts
Particularly interesting: despite identical building shapes, there were some significant differences in energy consumption - depending on the heating behaviour and ventilation by the residents. This emphasises: Building physics and user behaviour must be considered together.
Circular economy with a future
The timber house also performs best in the Urban Mining Index. Almost half of the materials can be reused at the end of their life, while the rest can be utilised to generate energy. Brick, on the other hand, has almost 100 % of primary raw materials - only around a fifth can be recycled. Concrete construction is in the middle of the field.
Our perspective
With Leidorf We are following this development with great interest. As a specialist in CNC and robot production in timber construction, we see simple, single-variety constructions offer great opportunities for sustainability, deconstructability and automation. The findings from Bad Aibling strengthen us in our mission: rethink wood - simply, precisely and sustainably.

Wood is good for you - scientifically proven!
A meta-study by the Technical University of Munich summarises numerous scientific studies and shows that the use of wood in construction has measurable positive effects on health and well-being.
Particularly noteworthy are:
✔ Improving the quality of life
✔ Antimicrobial properties - fewer germs on surfaces & in the room air
✔ Increased well-being & better ability to recover
✔ Demonstrable increase in performance & higher stress resistance
✔ Promotion of social interaction & helpfulness
Other studies also show that wood in interiors:
✔ Increases creativity and problem-solving ability
✔ Lowers blood pressure & heart rate - good for the cardiovascular system
✔ The dwell time of viruses on surfaces is reduced
These findings make it clear that wood is not only a sustainable, but also a particularly people-friendly building material.

Sustainable building with wood
with state-of-the-art wood processing!
The construction industry is facing enormous challenges: The pressure to reduce CO₂ emissions, use resources more efficiently and at the same time build flexibly and economically is greater than ever. Sustainable construction with wood offers an answer to these questions. As a natural, renewable raw material, wood has the potential to revolutionise the construction methods of the future - provided that modern production methods are used that guarantee precision and efficiency.
Here comes Leidorf into play. We specialise in the production of timber construction elements and rely on the latest CNC and CAD/CAM technologies. This enables us to produce highly complex and precise timber joints that completely dispense with metal fasteners. These "pure" timber joints are based on traditional carpentry techniques, which we reinterpret using modern, computer-aided production methods.
Research meets practice
Recently, a research project funded by the German Federal Environmental Foundation (DBU) developed an innovative timber frame construction method. This construction system, which utilises 100% timber, combines sustainability with flexibility. The construction method was designed to meet the challenges of fire protection, building physics and sound insulation requirements. At the same time, it remains flexible enough to allow for different living requirements and room configurations.
Even though Leidorf was not a direct partner in this research project, we are proud to have been able to realise this pioneering construction method with our technologies. Our CNC and CAD/CAM manufacturing methods are ideal for producing the timber joints developed in the project efficiently and precisely.
Why timber construction is the future
Wood is not only a CO₂-neutral building material, but also serves as a long-term carbon store. Compared to concrete or steel, significantly less energy is consumed in the production of timber construction elements. In addition, wood can be easily recycled or reused in buildings at the end of its life cycle. Sustainable timber constructions, such as those developed in the DBU research project, lay the foundation for environmentally friendly and sustainable construction projects.
With our modern production methods, we at Leidorf are able to fully utilise the potential of timber construction. Thanks to CNC and CAD/CAM technologies, we can produce even complicated geometric connections with the highest precision, guaranteeing a durable, stable and sustainable construction method.
Projects of the future
One example of the successful implementation of this new construction method is the "Collegium Academicum" project in Heidelberg. Here, the flexible timber frame construction system was used for the first time in a multi-storey residential building project. This innovation proves that sustainable timber construction not only makes ecological sense, but is also economical in practice.
At Leidorf, we look forward to integrating these technologies into future projects and making our contribution to the sustainable transformation of the construction industry. Using wood as a building material and state-of-the-art production methods, we offer solutions that not only protect the environment, but also enable high architectural quality and flexibility.

Building type E
is intended to make building in Germany easier and therefore more cost-effective
Building type E is intended to simplify construction by reducing superfluous standards and regulations. The aim is to avoid certain technical standards through negotiations between experts and thus enable more favourable and flexible construction projects. The application is aimed at construction projects carried out by experts while maintaining essential safety standards. This could encourage innovative timber construction projects that are resource-efficient and modular, as the absence of excessive regulation gives creative timber construction methods more room for manoeuvre.

The project uses Metsä Wood's Kerto® LVL wood products to recreate the iconic structure and shows the future of wooden skyscrapers.
Timeless wisdom in modern minimalism
Diogenes, Buddha, Jesus and the Tiny House as a symbol of simplicity and inner peace
The Tiny House is part of a long tradition of frugality and simple living that stretches back to figures such as Diogenes, Buddha and Jesus Christ. These historical figures consciously chose to live with minimal possessions in order to focus on the essentials - be it the search for wisdom, spiritual enlightenment or the spreading of a religious message. In the modern context, the Tiny House mirrors this approach, allowing residents to live with less and thereby gain freedom, clarity and focus.
This tradition emphasises that true happiness and fulfilment cannot be achieved through material possessions, but through inner values and simplicity. The Tiny House, as a symbol of modern minimalism, is thus in line with the philosophical and spiritual teachings of these great thinkers and spiritual leaders.

Hybrid timber construction: the future of sustainable building in Germany?
An interview on Holzbauwelt.de highlights several trends in timber hybrid construction. This construction method combines timber with other materials such as concrete, particularly for base storeys and staircases. Timber hybrid construction is becoming increasingly dominant in multi-storey construction, as it combines sustainability and serial construction. There is also growing acceptance among architects, planners and construction companies with regard to future projects. Timber construction is seen as a solution for sustainable and affordable living space, especially from 2025, when the new construction segment is expected to recover.

Wood reserves in Austria!
In accordance with the principle of sustainability, less wood is removed from the forest in Austria than grows back. According to the growth of the last ten years in the productive forest 89 per cent were harvested, while 11 per cent remained in the forest.
This strategy contributes to a continuous increase in timber reserves.
Since the 1960s, this has risen by around 50 per cent and currently stands at 1,173 million Metres in stock. Of course, this development can be seen throughout European forests. As a result of active forest management, Central Europe's timber reserves have been reduced by 8 billion Stock cubic metres This is 7 times the wood reserves in Austria.
Wood in the future?
The future of wood in Austria is secure! In the study "Timber availability in Austria" The sustainable utilisation potential of the Austrian forest for the next ten years was examined in a study. The result is promising: wood will continue to be abundant in the future. However, flexible management adapted to future climatic conditions is crucial. On the one hand, this means thinning old-growth stands and, at the same time, implementing regeneration measures.
It is also important to consider wood in the context of a sustainable life cycle. We focus on innovative, durable wood products and the efficient use of this valuable raw material. The future definitely belongs to sustainable building materials!

A Tiny House please
Why more and more small houses are being built
There are several reasons why the demand for Tiny Houses has increased in recent years. Here are some possible explanations:
Cost: Tiny houses are often less expensive than conventional properties. They require fewer materials and less energy to build and operate. This makes them attractive to people looking for a low-cost housing solution, especially in areas with high property prices.
Prefabrication: Due to a high degree of prefabrication, Tiny Houses can be manufactured in the factory regardless of the weather. The fully equipped module is transported to the building site. Assembly can thus take place in the shortest possible time.
Sustainability: Tiny houses are usually more energy efficient and have a smaller ecological footprint than larger houses. They require fewer resources to build and operate and can often be powered by renewable energy. This attracts environmentally conscious people looking for a sustainable housing option.
Minimalism: Tiny houses promote a minimalist lifestyle, where one concentrates on the essentials and frees oneself from unnecessary possessions. Many people see this as a way to free themselves from material ballast and live a simpler, more focused life.
Flexibility and mobility: Tiny houses offer the possibility to be flexible and live in different places. As they are compact and often built on wheels, they can be easily transported. This is attractive for people who like to travel or live in different locations without having to commit to a specific region.
Housing shortage: In some regions there is a shortage of affordable housing. Tiny houses can offer an alternative by creating living space in limited areas. This is particularly relevant in urban areas where housing is scarce.

Life cycle assessment: Wood performs better than before
In Switzerland, an updated version of the so-called KBOB list, which maps environmental impact points, primary energy and greenhouse gas emissions, was published at the end of April. Wood products now score significantly better than before. This could be exemplary for Austria.
Change Carbon reservoirs
Glulam rated better
What is also new is that glued wood products now perform better with regard to greenhouse indicators. For glulam, for example, there has been a serious change. "Here it has been shown that the expenses in production are significantly lower than previously assumed," explains Dr. Rolf Frischknecht, who heads the company specialising in life cycle assessment consulting and research. treeze conducts. The situation is completely different for conventional building materials. Concrete, for example, is now rated worse on all three points - environmental impact, greenhouse gas emissions and primary energy.

After the Oö. Building regulations are sufficient for a Carport up to 50 m² Built-up area before construction a building notification (§ 25 Abs. 1 Z. 9 Oö. Bauordnung 1994); for larger carports a building permit would be required. The prerequisite is that a carport (= protective roof) is actually present. If the structure is "predominantly enclosed" and thus can already be assumed to be a building, a building permit would only be required up to a built-up area of 35 m2. m² a notification obligation exists and, in addition, a permit is required (cf. the definitions of shelter and building in § 2 line 12 and line 23). Oö. Building Technology Act 2013).
Non-residential ground-floor, single-storey and detached buildings resp. Protective roofs, each with a built-up area of up to 15 m2in so far as they are located in building land according to the zoning plan and in accordance with the building regulations applicable to them. resp. The following provisions of spatial planning law, in particular those of the zoning law resp. The building authorities do not require prior notification of construction or approval for construction work carried out in accordance with the development plan. However, in order to clarify whether all requirements are met, we recommend contacting the building authority in advance!
Additional information Leidorf:
The definition of a shelter is as follows:
Shelter roof: a roofed, accessible structure not enclosed on all sides, which serves primarily to protect against the effects of the weather, such as open stand structures, flying roofs, pavilions and the like, insofar as it is not a building.
Information on this: 2 sides must be open so that it is a shelter and not a building.

Join in: Donate heat for the needy now
Leidorf Holztechnik donates wood briquettes to Upper Austrian food banks
Everything is becoming more expensive: electricity, food and even heating. Pellets have just reached an all-time high of around €350 per tonne. For people on low incomes in particular, the burden is becoming greater and greater. The company Leidorf Holztechnik from Altheim / Geinberg would like to set an example for more humanity. The company wants to support those who are hit hardest - with free wood briquettes, which are distributed at the Upper Austrian food banks and also at partner food banks in many regions of Austria.
Fundraising campaign launched for the needy
Leidorf has set up a donation page so that even more heat can be donated. At www.Leidorf.com/spenden you can support the action. With a donation of 25€, a family can heat for 1 week. You can also contribute 100 € for heat for one month or 600 € for a whole winter. Donations can be made by bank transfer, PayPal or credit card. Especially interesting for companies: The donation to the OÖ Tafeln is deductible as a special expense in the tax return.
Leidorf Holztechnik successfully combats the shortage of skilled labour
The shortage of skilled workers is now affecting all companies in Austria. Unfortunately, the Corona pandemic has further intensified this development. That's why the Leidorf company went all out for Simo, a Moroccan, to make employment possible.
GEINERBG. At the beginning of 2021, Leidorf received an application from a student. Simo, a young Moroccan, studied automation technology in his home country. After completing his bachelor's degree, he moved to Poland to complete a master's degree in Poznan. Simo found videos of a wood technology robot on the Internet, which is located in the Innviertel region at the Leidorf company. The robot CNC system fascinated the young man. He therefore sent an online application to Geinberg.
It quickly became clear: Simo is serious
Studies confirm: Wood emissions are not critical
In a 44-page brochure, the fnr has summarised "Living with wood - Influence of wood emissions on residential health". It provides information on the emissions of volatile organic compounds (VOC) caused by wood and wood products and summarises the latest scientific findings on this. It is based on 12 research projects that the Federal Ministry of Agriculture funded with a total of 3.6 million euros from 2015 to 2019.
No evidence of health risks
A research network under the leadership of the University Medical Centre Freiburg was responsible for the health assessment of emissions from wood and wood products in indoor spaces. Studies were carried out on the lungs, eyes, skin and nerves, among other things.
With the result: "that to date there is no convincing evidence of clinically relevant effects after exposure to indoor concentrations of wood emissions". A risk to humans from the release of emissions from wood and wood products into indoor air is not apparent.
What influence do CLT walls have on the air quality of living spaces?
In a research project of Holzforschung Austria and Wood k-plus in Tulln, the indoor air quality of a CLT room was investigated.
To get a realistic picture, the CLT room was expanded step by step and subsequently also used.
The tests make it clear that the indoor air quality of the pure CLT construction is very good.
CLT - Space:
Very good indoor air quality
However, the use of the room has a significant influence on the measured VOC concentrations.
An example: When peeling an orange, the VOC emission briefly rises to 37.5 times that of the empty CLT room. After one hour, the VOC levels are still 15 times higher than the empty solid wood room.
Use influences indoor air quality
- Burning scented candles
- Cleaning with all-purpose cleaner
- Application of an electric air freshener
- Cigarette smoking
- Lighting an ethanol stove
- Carrying out a cooking process
- Application of cosmetics
- Peeling oranges
- Application of parquet care products or wood polish
