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.

Energy Code for Owners and Contractors: Lessons from the Field

Virtual Event

Join us for an engaging panel discussion exploring how the new energy code is being implemented across Institutional (including K–12), Large Commercial, and Multifamily building types. Representatives from Turner and Consigli Construction will compare project typologies, sharing real-world challenges, lessons learned, and what’s on the horizon. Topics will include pre-construction and cost considerations (a key concern for owners), execution of design intent on projects that have built in the new code, quality control strategies like mockups, and the role of design teams in accurate pricing.

Building Science: Principles to Practice (3 Part Course)

Virtual Event

In this two-part training, we'll explore the fundamentals of how heat, air, and moisture relate to the building enclosure and how those loads shape durability, efficiency, and comfort. Participants will develop the ability to identify enclosure performance drivers and challenges and learn to build from the lens of the local climate, code requirements, and construction realities of New England. Participants will also leave with an understanding of how design choices affect comfort, durability, and efficiency long after occupancy, allowing them to implement these principles into their projects.
