Building Passive House: Costs & Long-term Payback

In the last few years, states and municipalities have committed to becoming carbon neutral by a certain date. One of the first targets to achieve carbon neutrality is advancing building energy codes. But what is the cost to building owners? What long-term benefits will they see from building to the advanced codes? Decarbonized construction comes with an initial price, but Consigli has the in-house resources to ensure long-term payback and best prepare your project for advanced net zero and Passive House requirements.

Take Massachusetts. The majority of the State uses a “stretch code” for minimum building energy performance requirements. Historically, the stretch code has been defined as 10% more efficient than base energy code. To study the feasibility of a more advanced stretch code, the Massachusetts Department of Energy Resources (MA DOER) contracted a group of consultants. Consigli performed nine unique pricing exercises, analyzing various building prototypes. As a result, the team determined cost premiums for Passive House levels of energy performance across building options, as well as the cost to go all-electric in those scenarios.

As cities and states evaluate advanced building energy codes, Consigli’s analysis of the MA stretch code can serve as a measuring stick for what to expect.
