Hot Water Generation:
Meeting the living building challenge The building will utilize a catchment system that allows the storage of grey water into cisterns for use in irrigation or non-potable uses. The building will use a living machine to recycle the everyday water uses and allowfor the building to have net zer water.
Hot water generation is done with the use of solar hot water systems that will be location of the roof of the building.
Grey Water Usage:
The design will incorporate a number of green walls and rooftop/ terraced gardens. These areas will need a substantial amount of water to maintain them. Grey water will be used for the maintaining of these areas. Access grey water will also be stored and further purified by the living machine. This system will help reduce the amount of water waste and reduce the amount of water needed to maintain this building.
Relationship of fire safety and water system:
The building will be fully sprinkled and will have stand pipes located with in the stair towers.

Primary Cistern Living Machine:
Rainwater harvesting will be a main focus for this project. A number of different locations on and around the building will act as a water collection for several cisterns. This locations include rooftop spaces, terraced spaces and site gardens.
The primary contributors of greywater to the system are showers, bathroom sinks, and washing machines. Although rainwater is the freshest without treatment of the three types of water (black, grey, rain), greywater is a close second. If there is not enough rainwater falling or stored to be used for all the potable water needs of a house, greywater can be treated and used to supplement the rainwater. It requires more energy to treat, but overall would be less expensive than purchasing more water from the city. The living machine will be integrated on the second floor exterior roof area providing natural elements both within the building as well as on the exterior of the building to provide an educational aspect to those who both work or visit the building. By using this living machine, it will allow for net zero water use.
