WORKSHOP 1: Are We Afraid of What We’ll Find? Using Real Buildings to Improve ASHRAE Standards and Publications
Chair: Joy Altwies, Ph.D., P.E., University of Wisconsin-Madison, Madison, WI
This workshop explains the results of a recent ASHRAE research project, 1627-RP, that studied the actual performance of buildings built using the ASHRAE 30% AEDG for schools and offices.

SEMINAR 22: Feedback: The Essential Ingredient for High Performance Green Homes
Chair: Audrey Dupuis, Pageau Morel, Montreal, QC, Canada
In high performance homes, comfort drives design, design drives energy use and careful design choices drive actual energy performance and occupant satisfaction. However, thermal comfort standards don’t include energy efficiency compliance requirements, leading to mismatches between comfort and energy efficient designs. This seminar explains why and how to use the vocabulary of thermal comfort as the first solution in solving residential energy problems. It also describes how feedback tools can be useful in calibrating modeling inputs to verify and ensure that actual performance outcome are achieved by design. The cost of poor design choices is also discussed.
