Daylight Modeling

Once you’ve made the important decision to introduce natural daylight to a space, there are still endless ways to go about it.

The amount of daylight required in a space varies with the specific task(s) being performed and the age of the occupants.

Traditional glazing with glass does not control the sunlight entering a space, often introduces glare issues and is not daylighting at all.

Daylighting is a sustainable building practice. It reduces electric and HVAC costs and provides proven health benefits for humans.

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.

As the world has come to realize and accept the importance of daylighting spaces for health, wellness and sustainability, daylight modeling software has advanced to provide more efficient and beneficial reports.

We do all our modeling in house and have for over 15 years. Our daylight modeling group is a multiperson team dedicated to executing your model and interpreting your results.

Daylight is a human right. Kalwall is first and foremost a family company founded on the belief that light is life and daylighting, done right, is something every building occupant deserves.

An annual illuminance metric that describes multiple categories of “usable” lux levels in a space, reporting a percentage of floor area that falls within a specified illuminance range for 50% of the time.

A measure of annual daylight sufficient for a given area, reporting a percentage of floor area that exceeds a specified illuminance level (e.g., 300 lux) for a defined analysis period (10 hours/day, 365 days/year).

A measurement to help limit excessive sunlight in a space. Defined as the percent of a space in which direct sun exposure exceeds a pre-defined threshold (e.g., 1000 lux) for some quantity of hours (e.g., 250 hours) in a year.

Point-in-Time Radiance Simulation—A metric that looks at specific light levels at a set day and time using localized sky conditions to review lighting design and glare.

Helps to identify potential problem areas where glare is a concern and where visual acuity is critical; used for analysis in work/study areas.

The metric for measuring biological effects of light on humans, used in the WELL v2 Standard.
