Existing Whole-House Solutions Case Study: Inverted Attic Bulkhead for HVAC Ductwork, Roseville, California
In this project, the Building America research team, IBACOS, worked with K. Hovnanian Homes to monitor the effectiveness of the space conditioning system in a 2,253-ft single-story slab-on-grade ranch house for an occupied test house (new construction) in Roseville, California. One year of monitoring and analysis focused on maintaining acceptable temperature and relative humidity levels in several rooms of the home, as well as room-to-room differences and the actual measured energy consumption by the space conditioning system. To describe the performance and comfort in the home, the research team selected representative design days and extreme days from the annual data for analysis. To ensure that temperature differences were within reasonable occupant expectations, the team followed Air Conditioning Contractors of America guidance. At the end of the monitoring period, the occupant of the home had no comfort complaints in the home.
