Third-Party Validation

Home » Daylight Modeling » Third-Party Validation

We have invested significant resources to make sure the data used in our daylight modeling is accurate and unbiased. Through independent product measurements, we have validated materials files that are used in daylight simulation programs, such as ClimateStudio.

The light diffusion data on Kalwall panels was organized through the National Research Council (NRC) Canada and tested by the Solar Energy and Building Physics Laboratory (LESO-PB). Our light transmittance values and solar heat gain coefficients were validated by the National Fenestration Rating Council (NFRC). In addition, we participated in studies with the University of Oregon’s Energy Studies in Buildings Laboratory to collect data on our spectral power distribution. This allows us to accurately provide light dosage measurements at individual wavelengths.

The power of all this data comes together in numerous ways. For example, we can use the ALFA software to determine blue light dosage (which is important to maintain circadian rhythms in daylighting design). The software would calculate how much blue light is received by building occupants using measurements of that wavelength coming through the Kalwall panel, the specific light transmittance value and diffusion pattern.

We’re continually participating in further studies and research to ensure our advancing technology meets the needs of today’s world and delivers the superior performance our company promises.

No other lookalike product on the market can provide this level of independent data validation.
