This presentation focuses on the new energy guidelines and how to make tight houses meet the ASHRAE Health Based Standard 62.2 related to fresh air requirements.
Speakers Camilo Parra, AIA, and Polly Ledvina, PhD, LEED AP Homes, discuss different climatic regions and passive design strategies for these regions. They outline the energy guidelines that apply to new house construction in the United States and review how some of the guidelines are not region specific. They discuss problems associated with achieving the energy guidelines with a house’s mechanical system and how these problems can be overcome. Lastly, they explain the ASHRAE Standard relative to fresh air. Stephen Schreiber, FAIA, moderates.
This September 10, 2012 presentation is a part of the ongoing Housing Knowledge Community research webinar series. View the complete series archive.
