HI, i have 2 questions to ask:
1.Now i have a hotel project in china. In this project, Several squatter toilets(with water tank) are designed and will be constructed in the future. But i can`t figure out which fixture family is more appropriate for it as the baseline(water closet or blow-out)?
Also i want to know the exactly definition of blow-out fixture.

2. Also in this project. 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. These areas are paved by wood, pebble,tiles instead of traditional roof material(paints, concrete etc.). Can we treat these parts as vegetated roof? Or equivalent SRI for these parts by material color is more acceptable? If we equivalent SRI for this parts, is it acceptable i upload a test report or cut sheets of the equivalent material? (For example, if i have a pavement constructed by green tiles, and we know the SRI of green paints is 21, can we submit the SRI of green tiles as 21?)
