Guides and Case Studies for Mixed-Humid Climates
The Department of Energy (DOE) has developed a series of best practices and case studies to help builders improve whole-house energy performance in buildings found in mixed-humid climates.
Best Practice Guides
New Construction Case Studies
Project: North Point Lot 5 — Frederick
Builder: Nexus EnergyHomes
Profile: This urban infill community with 24 duplexes, 19 townhomes, and 7 single-family homesfeatures SIP walls, geothermal heat pumps, solar PV, and a proprietary energy management system.
Project: Eco-Friendly Home — Sagaponack
Builder: Ferguson Design and Construction
Profile: This houseincorporates double walls with staggered studs, poured-in concrete basement, and double-pane, argon-filled windows.
Improvements to Existing Homes Case Studies
Project: Bay Ridge Gardens—Mixed Humid Affordable Multifamily Housing Deep Energy Retrofit — Annapolis
Building Componenets: Envelope, HVAC, lighting, domestic hot water
Profile: Approximately 43% energy savings are achieved in a 1970s multifamily building through standard, non-invasive retrofit measures.
You may also find case studies and guides that work across all climates on the All Climates page.
For additional, updated information on hundreds of building science topics that can help you build or retrofit to the most recent high-performance construction criteria, including the latest version of ENERGY STAR and the DOE Challenge Home requirements, see the Building America Solution Center.
