PNNL
This report describes the experimental design and results of testing the energy performance of Hunter Douglas double-cell cellular shades under various control schemes in the Pacific Northwest National Laboratory’s (PNNL) Lab Homes in both heating and cooling season experiments.

Low-E Storm Windows:

LBNL
Lawrence Berkeley National Laboratory (LBNL) performed a field evaluation comparing the performance of low emissivity (low-E) storm windows with both standard clear storm windows and no storm windows in a cold climate.

PNNL
To examine the energy, air-leakage, and thermal-comfort performance of low-e storm windows, a field evaluation was undertaken in a matched pair of all-electric, factory-built “Lab Homes” located on the Pacific Northwest National Laboratory (PNNL) campus in Richland, Washington.
