WINDOW WALL RATIO
THE WALL-WINDOW RATIO CALCULATIONS DETERMINE THE AMOUNT OF OPENINGS IN A WALL WHICH WILL ALLOW DAYLIGHT INSIDE THE STRUCTURE. DEPENDING ON THE GEOSPATIAL LOCATION OF THE STRUCTURE, WE CAN DETERMINE HOW MUCH DAYLIGHT CAN REPLACE ENERGY USAGE FOR LIGHTING THE BUILDING.

1 - A building has a floor slab that is 20’ x 30’. Each exterior wall is 20’ tall. Windows comprise 25% of the walls. There are two (2) doors and each is 3’ wide by 7.5’ tall. The hip roof is 1,400 sf total. What percentage of the overall building is each component?
2 - A building with a flat roof has the elevations below. What is the WWR (Window Wall Ratio)? Calculate for each facade and for all walls combined. We are only looking at walls in this case.
