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 Transmission qualities of your materials. We measure and calculate the following solar optical properties of materials:

• Transmittance: Total Solar & Visible Light
• Reflectance: Total Solar & Visible Light
• Total UV Transmittance
• Openness Factor

Our testing is performed per ASTM (American) and/or EN (European) standards. The software utilized for subsequent calculations is either the Window program 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.
