Water Savings
Homeowners are becoming increasingly aware of water conservation. Water heating is often the largest energy expense in a home after heating and cooling. Green Building focuses on strategies and technology that allow us to use water more efficiently, up to 39% compared to conventional building.
Low flow faucets, toilets, shower heads, tankless water heaters, as well as Energy Star washing machines and dishwashers, saves water and energy.
- Energy Star Water Conserving Appliances
- Lavatory Faucets Less Than 1.5 GPM
- Water Closets Flush Value 1.28 Gallons
Hot Water Circulating Loops
A typical hot water system has piping that comes from the water heater in a “tree” configuration, with a main trunk and smaller branches that go to each fixture. When you turn on the hot water tap, you must wait for the cool water to flush out of the piping before you get hot water.
A recirculating system is piped differently using an insulated hot water loop that travels throughout the house and gets close to all the fixtures that use hot water. There are very short branch pipes that connect this loop to each fixture. A pump is used to circulate hot water so that hot water arrives at the fixture very quickly.
Tankless Water Heaters
Tankless Water Heaters heat only the water that is needed as it passes through the coil. This eliminates energy costs as it heats only the amount of water that is needed.
Rainwater Harvesting
Install a rainwater harvesting system while building your Green Home to collect rainwater from roofs and into a storage tank. The collected rainwater can then be used for other purposes such as toilets or sprinkler systems.
