We perform solar energy measurements on window treatments and other materials used to block the sun's intense radiation -- heat and light. Through measurements and subsequent calculations, we can determine the Absorptive, Reflective, and Transmittance qualities of your materials. We measure and calculate the following solar properties of materials: Transmittance -- Total as well as Visible Light Reflectance Total UV Openness Factor Our testing is performed per ANSI/ASHRAE 74-1988 (ASTM E 1084-86). The software utilized for subsequent calculations is either Window 5.2a from Lawrence Berkeley National Laboratory or custom software provided courtesy of our colleagues at Arizona State University. Our instrumentation is calibrated with traceable standards on a regular basis. If you would like us to perform solar energy measurements on your materials, or if you have questions about solar testing, please select from one of the following options: Call or email Don Pershing (information provided below) Request a Quote or Testing Most of our testing is fairly customized, so we cannot provide a price list.
