Environmental Impact of a Mono-Material Timber Building Envelope with Enhanced Energy Performance

Broader adoption of timber construction is a strategy for reducing negative greenhouse gas (GHG) emissions created by the industry. This paper proposes novel solid building envelope that uses computational design and digital fabrication to improve buildings’ energy performance. Timber beams are sawn with deep slits thermal insulation milled various joints airtight, structural connections. To minimize embedded simplify disposal, assembled without adhesives or metal fasteners. The evaluated resistance airtightness, duration power output during sawing. Finally, Lifecycle Assessment (LCA) carried out. Global Warming Potential (GWP) compared other wood systems similar conductance. Compared constructions physics properties, proposed system showed lower GWP values (−15.63 kg CO2 eq./m² construction). development analysis demonstrate potential use digitally controlled subtractive manufacturing improving quality achieve higher environmental performance in envelopes. However, further optimizations may be necessary reduce required materials production energy.
