Average incremental cost for Phius multifamily projects over baseline
Incremental cost for many multifamily projects due to cost savings from reduced mechanical system size and distribution infrastructure
Larger buildings inherently have better economics to achieve Phius Certification than single-family homes. They have a lower surface-to-volume ratio, meaning investments in the building enclosure affect a larger area of conditioned space. Plus, the internal load density found in multifamily buildings lowers the required thermal performance of the enclosure to strike the optimal energy balance.
