I had become frustrated with the lack of a database of European testing laboratories so I created my own.

We have a roof that consists of a flat roof with a dome. How do we calculate the dome area since some of the surface area is actually the "sides" of the dome.

Hi! We are working on a project that has a large green roof. Some parts of it are covered with gravel (crushed stone) as a surface to walk on.

I have a hotel project in china. Our client will build a roof garden. Some areas of roof garden is vegetated roof, and other area will be construct as lane, tennis court or other things.

I apologize if this is a repeat comment.

Has anyone ever used the aged or 3 - year solar reflectance value instead of the the initial reflectance?

What defines a roof for this credit? Is it slope, construction, or function? I have a project with a mansard roof. It has a 65% slope, very steep.

I am working on a multifamily residential project where the roof will be accessible to residents. Part of the roof will be green, and pavers will be installed on the non-green parts.
