Large areas of glazing may cause unwanted heat gain and compromise energy efficiency. However, daylighting may require less glazing than you think—about 40% window-to-wall ratio may be more than you need. Glazing closer to the ceiling will have a greater daylight benefit than glazing near the floor—anything below 30 inches is considered to have no daylight benefit.

To reduce cooling loads, use overhangs, lightshelves or fins, courtyards, and lightwells to block high-angle summer sun and low-angle morning and afternoon sun. These strategies also reduce glare and can improve daylighting by reflecting it deeper into th

To reduce heating loads, use daylighting strategies in tandem with passive solar heating strategies, such as using materials with greater thermal mass and orienting the building for maximum solar gain.

Total the areas of regularly occupied spaces that have both direct-line-of-sight to perimeter glazing and access to views while seated (at 42”). Divide this value by the total area of regularly occupied spaces to confirm if the design provides greater than 90% of regularly occupied areas with access to views. This is done in the LEED Submittal Template. Upload plans and all required supporting documentation to LEED Online.

Total the square footage with access to views and enter this value in the corresponding regularly occupied space entry in the LEED EQc8.1-8.2 Glazing Factor and Views Calculator.
