Stretch & Specialized Code Basics

Virtual Event

This course covers the 225 CMR 23.00 MA Commercial Stretch and Opt-in Specialized energy codes applicable from July 1, 2023 and including February 2025 updates. The presentation encompasses the different pathways available for code compliance, requirements for each section (envelope, mechanical, plumbing, and electrical), and an overview of how the different components work together. Participants will also learn how the Fossil Fuel Free Pilot communities program may use the Stretch Code as a tool to help meet building performance and electrification goals. This course is intended for all building industry professionals, including but not limited to architects, engineers, consultants, modelers, developers, owners, and contractors.

Energy Code for the Building Envelope (2 Part Course)

Virtual Event

This two-part training is intended for new construction and existing building alterations and additions following the 225 CMR 23.00 Commercial Stretch Energy Code. Case studies and real-world calculation examples will reinforce key concepts, and attendees will apply their knowledge through hands-on exercises with a sample project.

TEDI Modeling

Virtual Event

The training will review the method and best practices of conducting a Thermal Energy Demand Intensity (TEDI) model as required for compliance with the Stretch Energy Code. Case studies and lessons learned from permitted buildings will be used to demonstrate model results and balance adjustments to design through the design process to reach a final compliant model.

Energy Code for Low-Rise Residential Buildings (2 Part Course)

Virtual Event

In this two-part training, we will review the differences in Residential codes across Massachusetts' three energy codes – Base code, Stretch, and Net Zero – for Single Family Homes, existing, Additions, and Renovations. Various wall assemblies, air barriers, windows, and ceilings/roofs will be discussed. Participants will gain an understanding of the embodied carbon credit, as well as mechanical systems, solar systems, and electrical vehicle requirements. Additionally, participants will learn what is needed to build, test, and verify to the new code for these project types. While there are no prerequisites to join this training, it is recommended that attendees have already taken the level 1 courses taught by PSD and MassSave.
