CS-2009 SSc7.1:Heat Island Effect—Nonroof

How to take account of the roof skylight with the calculation?

We have a high rise commercial office building project is going to pursue LEED CS certification. And I have two questions for the heat island effect calculation need your kindly help: 1. This building has a 5 floor high atrium in the first floors and the top of the atrium will be glass skylights. this project will only have underground car parkings, can I apply for 100% car parking under cover for SS7.1 to get the ID point? 2. For SS C7.2 calculation, should I deduct the roof top skylight area from the total roof surface area? Thank you very much!

Shenhao, 1. Yes you can apply for 100% car parking and get the ID point as long as your roof material has a SRI> 29. 2. To calculate the roof area subtract out any skytights and mechanical systems.
