Hello Group

I have just started working on my first energy modeling
project. I have two questions:

- How do I model roof reflectivity. I want to model a roof of 4 inch
concrete with 1 inch stucco at the bottom and top and cover the roof with
cool roof tiles. I am not sure how I can account for the energy efficiency
gains compared to base case through a high SRI roof.
- I am trying to model a large gated community with 330 villas and 7
other common buildings. As someone suggested on this group I am modeling
each building type separately and using excel to come up with a total
energy usage. But I am not sure how to model the street lighting and
landscape lighting at the exteriors. We plan to use solar street lights and
I want to demonstrate the savings through use of solar energy.

Many Thanks
