The Building America Program hosted this no-cost webinar that discusses the research on comfort in residential buildings. Results are presented from 37 new homes that were monitored in the Southeast United States. The presenters also discuss results from a modeling exercise that identified the impact house design, system design, and control strategies on comfort and energy consumption. IBACOS has begun investigating a plug and play duct system that is intended to significantly simplify the design and installation process of ductwork, as well as reduce the risk that poorly installed ductwork will hamper performance. Finally, IBACOS discusses the differences in performance of a standard system, a small diameter system, and a ductless mini-split system in a set of new construction town homes.
