I chose to install the graywater collection system in my building to make it more sustainable. This represents a great percentage for the EDGE certification by also having efficient plumbing fixtures (low water consumption). With these installations, the building meets the criteria required for the Water section of the EDGE Certification with approximately 26% (minimum of 20%).
Men's Restroom:
- 1 Urinal (2L per flush)
- 2 Dual-Flush Water Closets (5L first flush, 2L second flush)
- 2 Sinks with Low Flow faucets (2L / min)
Women's Restroom:
- 3 Dual-Flush Water Closets (5L first flush, 2L second flush)
- 2 Sinks with Low Flow faucets (2L / min)
There is one restroom for each gender in each floor in both buildings. Each restroom with 1 handicap bathroom.
There were not many challenges for this system since my building was initially designed with a mechanical room next to it, so it was a short route from the system to the room. It was also designed to have the bathrooms in the same location so they are stacked in each floor, making it easier to connect the risers. However, I had to rearrange the mechanical room and the storage to give more space for the equipment for the HVAC system. I changed its location to the room next door, where the storage was, and switch an office for the new storage room. Even if I lost one office, this was really an "extra" office since there already are 2 big offices more in the same place that can be used as an administration office and one for use.

There weren't much issues with merging all the models. All the piping goes to the mechanical room on the back of the restrooms, so it is not intersecting any beams nor HVCA ducts.
The only "issue" I could see for this system was the intersection of the piping with the wall from the mechanical room. This is not really an issue since it is something that its fixed in the site, its part of the construction and piping installation.
