DESCRIPTION BENEFITS CONSIDERATIONS LEED (Planned)
Low Flow Fixtures

Install low flow water fixtures in all new and existing buildings

Reducing domestic water consumption

Reduce sewage flow from domestic water use

Reduce the amount of domestic hot water consumed, thus reducing energy for heating water

Low flow fixtures might have negative comfort effect

Adding insulation to walls might slightly reduce internal floor area

Economic viability generally neutral as market is stable
