Developing energy efficiency solutions for residential housing
A GTI team is working with the U.S. DOE Building America program to research and field-evaluate cost-effective retrofit packages for thermal envelopes and energy systems most appropriate for Chicago-area homes. GTI has led the efforts of the Partnership for Advanced Residential Retrofit (PARR) to develop measure guidelines for concepts that save significant amounts of energy for the retrofit market. The team has provided guidelines for maximizing furnace efficiency, applying combination space and water heating equipment, developing cost-effective upgrade packages for common building archetypes in Northern Illinois, multifamily building and steam system upgrades, and guidelines for combustion safety. PARR will continue its work over the next several years investigating optimal methods for managing ventilation, infiltration, and ducted air distribution systems. GTI has also created a Guide to Best Practices for Home Energy Retrofits sponsored by the California Energy Commission.
The Building Research and Consulting team of GTI’s subsidiary Frontier Energy
develops innovative approaches for achieving energy efficiency in new and existing residential and small commercial buildings through systems and whole building research and development.
A pioneer in the use of energy modeling to optimize building performance, DEG has applied this skill to develop and refine energy standards for California and to support programs such as California’s zero net energy initiatives. DEG has developed technology to improve building energy efficiency, and evaluated emerging technologies in the fields of HVAC, water heating, and building enclosures through laboratory and field monitoring. DEG carries knowledge from its R&D activities to the building industry through market transformation programs such as the DOE’s Building America and USGBC’s LEED for Homes, as well as private sector projects with builders and developers.
