Hi, I’m working on a High-rise residential LEED energy modeling project now. I have a question regarding the lighting. I’m using Energypro, and found out the lighting saving is zero from the calculation no matter what the design input is. Does that mean we cannot count on lighting savings for high-rise residential project?

2nd question: the first floor of this project is retail area. MEP wise, it’s for future use. So there is no design on that area. But this is a LEED NC project and the retail area is included in the architectural design, and will be included in the LEED scope. For this kind of situation, how should I model it?

3rd question: Can I treat the underground parking garage lighting as exterior lighting?

Any advice is appreciated. Thanks.
