Daylight Modeling

Optimize the use of daylight for comfort, sustainability and profitability

Good natural light is key to creating buildings that occupants love. A space correctly designed for daylight is visually and thermally comfortable. It can also be used as a passive strategy for saving energy, allowing users to turn off electric lights, reducing the building’s environmental footprint and operational costs.

However, allowing natural light into a space also means increasing solar heat gains. Careful planning is vital to balance the positive contributions of daylight, while minimizing discomfort caused by overheating or visual glare.

Our service

At RWDI, we use detailed computer modeling to help you capture the benefits of daylight while avoiding its unwanted effects. Our analysis begins with a thorough understanding of your criteria and goals. While our modeling delivers precise quantitative results, our team goes beyond numbers: we present solutions that are thoughtfully integrated with your project vision, working to shape design choices that balance technical and aesthetic concerns with your overall business goals.

We can also pair daylight modeling studies with complementary studies of energy use, thermal comfort, and glare. Our team of world-leading weather experts and building performance specialists will demonstrate how climate factors will affect daylight and energy use in your project and how design choices can create conditions for sustained operational success. As an independent consultant, we utilize our extensive modeling capabilities to help you rapidly and impartially assess multiple solutions, evaluating the effects of different options, to ultimately identify the approach that best meets your goal.
