The Consortium for Advanced Residential Buildings has worked with builders to assess the most practical cost-effective means to reduce home energy consumption and approach zero energy. Especially in multifamily applications, CARB has seen more developers explore solar domestic hot-water systems as part of the least-cost pathway.
Most older multifamily buildings in Chicago are heated by centrally metered steam or hot water systems. These buildings cannot operate effciently when these systems become imbalanced. The buildings become under and over heated, which causes tenant discomfort and higher energy use intensity.
Rea Ventures Group partnered with Southface Energy Institute, a member of the U.S. Department of Energy's Partnership for Home Innovation Building America research team, to develop a prescriptive approach for rehabilitating a portfolio of rural multifamily rental properties in Georgia.
