This session will describe process of early phase analysis that a design team can to test whether natural ventilation is a feasible comfort-conditioning system for a given climate and building configuration. The speaker will build on her “Natural Ventilation Top 10 Feasibility Questions” from an ASHRAE Journal article to cover compliance with ASHRAE Standards 55 and 62.1 and a discussion of the impact of climate change.
