RESAVE stands for Residential Energy Savings from Airtightness and Ventilation Excellence. The overall goal of this program was to reduce the energy spent in homes to condition air that enters from outdoors. This program provided important research and technical tools to advance the strategy of Build Tight, Ventilate Right. This approach combines high-quality building construction with optimized ventilation systems to maximize energy efficiency while maintaining acceptable indoor air quality. The program developed new technologies and recommendations for improvements to existing technologies.
Industrial partners were involved in the program to ensure that these technological developments will find their way into California homes. The program leveraged best practices and leading-edge building and ventilation technologies from California, the United States, Japan, and Europe.
In addition to technology development, this program made recommendations for changes to California State Energy Code for buildings (Title 24) together with providing the diagnostic and commissioning tools necessary to ensure code compliance. These tools will also help in market transformation by demonstrating the performance and value of good ventilation systems to consumers, contractors, building managers, and other potential decision makers and beneficiaries.
