Combining Passive House and mass timber construction presents an opportunity to optimize both operational and embodied carbon. The exposed wood CLT structure and building envelope elements offer numerous benefits including interior aesthetics, a healthier indoor environment, reduced use of interior finish materials, and shorter construction duration. However, to date, most CLT multifamily developments have been boutique condominium projects. This session will feature two market-rate CLT Passive House multifamily projects that represent different design strategies for viability and carbon impact. We will analyze their similarities and differences, material and systems choices, design challenges and solutions, synergies and tradeoffs.
