Title: Existing Whole-House Solutions Case Study: Passive Room-to-Room Air Transfer, Fresno, California

In this project, IBACOS, a U.S. Department of Energy Building America team, assessed a strategy for providing conditioned air to bedrooms when the bedroom doors are closed and measured potential thermal discomfort that occupants may experience when this strategy is used. Builders can use this information to discuss space conditioning options for low-load houses with their clients to determine acceptable comfort levels for occupants in these cost-optimized, energy-efficient houses.
