DOE Zero Energy Ready Home (formerly Challenge Home) is a blueprint for zero energy ready homes. When we make that statement, it’s impossible to justify huge thermal losses from ducts in unconditioned spaces. That’s why one of the program’s mandatory specs calls for ducts in conditioned space. However “ducts in conditioned space” isn’t a one-size-fits-all design requirement in ZERH. Over the last several years, DOE’s Building America research program its and partners have worked out the kinks on a toolkit of duct design strategies. In this session you’ll learn the pros and cons of these strategies so you can specify distribution systems that are effective in any type of project. The presenter for this webinar is Bill Zoeller of Steven Winter Associates – a leading Building America expert on the thermal performance of air distribution systems.
