Cellular Shades

First of its kind Xcel Energy Cellular Shade Rebate Program – Brings Savings and Comfort to Coloradans

A fact sheet from the U.S. Department of Energy’s Building Technologies Office.

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.

The nation’s first smart shade pilot program yields over 13% savings on electric bills. Baltimore Gas & Electric reports energy savings from automated shading solutions following year-long study, partnering with AERC and industry leaders Hunter Douglas and Rollease Acmeda.

Low-E Storm Windows

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.

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.
