Researchers in the CBTS are helping industry reduce energy use in buildings by conducting research on: Residential Buildings,
Commercial Buildings, Technologies, and Analysis and Evaluation.

Residential Buildings
Building America Program
Teams comprising researchers and members of the home building industry produce quality homes that use up to 70% less energy.

Commercial Buildings
High-Performance Commercial Buildings Research
Develop high performance whole-building design methods that integrate energy-efficient and renewable energy technologies in commercial buildings.

Technologies
Advanced Desiccant Cooling and Dehumidification Program
Researchers work with industry to evaluate advanced desiccant cooling and dehumidification systems and components and develop prototype systems.

Building Integrated Photovoltaics (BIPV)
BIPV systems can be integrated into almost any type of building to supplement grid-supplied power, reduce energy costs, and provide emergency back-up power during utility power outages.

Electrochromic Window Testing
Researchers evaluate and test electrochromic "smart" windows that save energy by controlling heat gains and losses.

Passive Solar Buildings
Developing high-performance whole-building design methods that integrate passive solar, energy efficiency and renewable technologies that can be used by the building industry to reduce building energy consumption.

Analysis and Evaluation
BESTEST
The BESTEST (Building Energy Simulation TEST) method evaluates design and analysis tools relative to their ability to adequately model
the energy performance of buildings.

Energy-10
An award-winning PC-based design tool that helps architects and building designers quickly identify the most cost-effective, energy-saving measures for small commercial and residential buildings.

SUNREL
A detailed hourly building energy simulation program that aids in the design of small energy-efficient buildings. SUNREL is temporarily unavailable.

Rules, Codes, and Standards
Rules, codes, standards, and guidelines for buildings, building equipment, and appliances.
