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.
There are nearly half a million multifamily units in Chicago. More than 60% of low-income individuals living in multifamily buildings in Chicago reside in buildings that are more than 75 years old. This situation presents significant potential for energy savings.
Massachusetts project converts school into 12 high-performance apartments that capitalizes on solar water heating technology.
Research showed the average net income increased by 1.6 percent.
This document helps utilities identify new, untapped datasets that are emerging related to the energy performance of buildings, and how this information can be applied to expand market intelligence and create business value.
