IBPSA-USA, Houston Chapter broke its long lull of inactivity in May this year. We combined our chapter meeting with the monthly meetings at AIA’s Building Enclosure Council. The presentation was titled “Three Little Buildings: The Story of Envelope Performance”. Through analysis of three case studies designed by Kirksey Architecture, the speakers explored lifecycle costs and energy performance implications of various envelope-related energy efficiency strategies. The analysis focused on the results of an iterative energy modeling process, which identified useful metrics that are not typically a part of building and facade design. The presentation was delivered by Kapil Upadhyaya, Colley Hodges & Alfonso Hernandez.
