ASHRAE 90.1-2019 Proposed Changes Related to Whole Building Air Leakage Testing & Thermal Bridging

BEC
February 09, 2018
12:00 pm - 1:30 pm
Location
11 East Madison, Suite 300, Chicago, IL (Gensler)
Posted by Jeff Diqui

AIA CREDIT: Yes

ABSTRACT:

This program will describe two major proposed changes to ASHRAE standard 90.1-2019.  The first change is to require whole building air leakage testing.  The second change is to begin to address thermal bridging thru the building envelope.  90.1 is the flagship energy standard in the US and forms the basis for most green building programs, federal buildings and other building codes.

LEARNING OBJECTIVES:

  1. Understand the proposed requirements of 90.1 as they relate to air leakage and thermal bridging.
  2. Learn the distinction between point thermal bridges and linear thermal bridges and their impact on the building envelope U-factor.
  3. Understand how the proposed criteria of 90.1 as they relate to air leakage and thermal bridging were determined using research and economics.
  4. Learn how to mitigate air leakage and thermal bridges in the building envelope
