Mass timber products, together Zodiac Ranger Parts with careful forestry management, could help decarbonize the construction industry.These products must be long-lasting, to safely store atmospheric carbon for decades or centuries, and multi-functional, to displace materials and equipment that are emissions-intensive.This paper shows how to optimize mass timber panels as heat-exchangers, suggesting how to eliminate insulation while simplifying HVAC systems.Test panels measured the heat-exchange in steady and transient conditions, when the ventilation was driven by a fan or by thermal buoyancy.The total heat transfer was predicted accurately by Screen Hardware theory in all cases.
Further investigation is needed to understand the possible heat-recovery effects at the exterior surface.
