Course 4: Understanding the 9th Edition Stretch Code
Stretch Code Overview and Compliance Options (1 hour) This course discusses energy code provisions specific to the Massachusetts stretch code, including the three available compliance paths – RESNET HERS, Passive House and ENERGY STAR. The presenter will also discuss how renewable energy tradeoffs for technologies such as solar PV, solar thermal systems, clean biomass stoves, or renewable primary heating systems. Available software programs and required documentation for each of these compliance paths will be examined.
Understanding and Reviewing 3 rd Party Documentation (1 hour) The second part of the course deals with documentation. Building inspectors cannot directly verify every aspect of the code, but luckily, there are experienced energy professionals who can provide verification and documentation of the most important energy code requirements. Clear and consistent documentation improves energy code compliance and saves time. This course covers critical documentation including ERI/HERS, ENERGY STAR v 3.1 reports, as well as PHIUS/Passive House. The presenter will review example reports and describe how to interpret essential data, along with keeping track of this information with a one-page checklist created by the Mass Save Energy Code Technical Support Program. The Stretch Code and Existing Buildings (1 hour) Two-thirds of all towns in Massachusetts are Stretch Code towns and residential renovations, alterations, repairs, and additions make up the largest proportion of building permit applications. Despite this, confusion abounds as to how the Stretch Code applies to existing buildings, such as when duct testing is required, how should ducts be insulated, and blower door testing requirements. This course will cover several of the most common types of existing home projects and describe the applicability of the most important energy code provisions.
