Honeycomb Solar Thermal Collector
The Honeycomb Solar Thermal Collector (HSTC) uses a honeycomb insulating layer to minimize heat loss by suppressing convection, making it particularly effective, manufacturers say, in cold climates, where many GSA facilities are located. The technology was installed at two test-bed locations, the Major General Emmett J. Bean Federal Center in Indianapolis, Indiana, and the GSA Regional Headquarters Building in Auburn, Washington. Researchers found that, for standard domestic hot water applications in which mains water is heated by an array of solar collectors and stored in a tank, the HSTC technology was up to 8% more efficient than typical flat-plate collectors.
