R3.2 Residential: Efficient Forced Air Distribution Part 2
T02-07-2862
COURSE DESCRIPTION In this course attendees will understand the importance of duct testing, sealing, and installation on the total performance of a house heating and cooling system. Attendees will be able to distinguish various code requirements based on duct proximity to the building thermal envelope. In addition, attendees will learn duct insulation requirements and methods. Attendees will be introduced to a customizable Duct and Envelope Testing (DET) reporting form to make demonstrating code compliance straightforward and efficient.

COURSE DESCRIPTION Bringing attic and crawl spaces inside the thermal envelope is a great way to simultaneously improve energy efficiency and moisture management. One of the main ways unvented attics and crawl spaces reduce energy waste is by bringing ducts and air handlers inside (which is a requirement of NYStretch and the NYCECC). This can also be cost-effective for builders as they eliminate the requirement for duct testing. But there are risks associated with installing these assemblies improperly, so it is important to meet all related requirements in the RCNYS. For unvented attics, these include a minimum R-value of air impermeable insulation or above-roof deck insulation and proper installation and location of vapor retarders. For unvented crawl spaces, builders must take care to install vapor barriers over exposed earth and provide a means of evacuating moisture. For both strategies, the use of spray foam also brings in fire safety requirements from the RCNYS for thermal or ignition barriers. This course will provide a review of the benefits of unvented attics and crawl spaces, related building science concepts, and energy and residential code requirements.
