Multifamily Buildings Retrofit Research Project(ST4047-1)

Association for Energy Affordability, In

Background

Researchers have speculated that variables such as building size, construction, number of units, and heating systems may contribute to the varying energy savings achieved in the multifamily sector through weatherization. Protocols and corresponding investment strategies to achieve maximum cost-effective energy savings are lacking. The intent of this project was to address issues attendant to achieving energy savings in the multifamily sector.

Project Description

Fuel-consumption and other data will be collected on a sample of 50 buildings of various sizes and construction types to discern the relationships between pre- and post-retrofit energy consumption, and to assess the direct and indirect impacts of energy-conservation measures (ECMs) of fuel consumption and indoor air quality. Bills for pre- and post-retrofit fuel use will be analyzed on 50 buildings, and for a control group of 30 matched buildings. A subset of 25 buildings will be subjected to more intense, field-based monitoring using fuel-flow meters connected to data loggers.

Benefits

A mean energy savings of 17.3% was achieved in the monitored buildings; and an energy savings of 18% was achieved in the fuel bill analysis buildings. Other findings suggested that indoor air quality is not negatively impacted as a result of weatherization, gross overheating within apartments is reduced, and energy management systems play a crucial role monitoring building’s operations.

Project Results

The recommendations resulting from this project provide valuable information to the Weatherization Assistance Program as guidelines for affecting the delivery of future multifamily building weatherization services. Research results were presented at a national forum.
