Over the past two years, Massachusetts and its consultant team has studied cost-effective commercial building approaches aligned with climate goals. This session will present a building-level review of the analysis done to inform Massachusetts’s upcoming stretch energy code and municipal opt-in stretch code. We will focus on a) Thermal Energy Demand Intensity (TEDI), b) critical role of envelope, thermal bridges, and air infiltrations, c) implications to carbon emission and fossil fuel use, and d) cost optimization for different commercial building types. The session will contain an opportunity for discussion between the design community and the DOER staff and consultants involved in the study.
- Describe the role that building envelope plays in GHG emission reduction goals and building life cycle costs.
- Summarize the building science considerations that are being used to inform updates to building code development.
- Define Thermal Energy Demand Intensity (TEDI) metric and how it can be used for low carbon building design.
- Explore how to optimize costs when following the new stretch codes.
