This paper presents a project by the Region of Durham, Whitby, Ontario, Canada to increase water and energy efficiency of single-family dwellings. The water and energy efficiency upgrades include three types of toilets: 3/6L dual flush (0.8 and 1.6 gal.) toilets, 4L (1.0gal.) pressure toilets and 6L (1.6gal.) toilets; premium low flow showerheads, front load washersand dryers, efficient dishwashers and fridges (the appliances are ENERGY STAR® rated).Outdoor initiatives include xeriscape front gardens and lawn care education. In partnership withthe builder, residents will also receive information on other indoor and outdoor water and energyefficiency opportunities.The efficient homes (a 100 Home Study Group) and "builder standard" (a 100 Home ControlGroup) in the same neighborhood are having their overall water and energy use monitored. Thein-depth monitoring consists of ten (10) homes from the Study Group and ten (10) homes fromthe Control Group being sub-metered. Sub-metering began in May 2005. In each home, there aresix water sub-meters for the front and rear exterior faucets, dishwasher, clothes washer (1 hot and1 cold water) and on the water heater supply. There are six electrical sub-meters for the washer,dryer, dishwasher, fridge, stove and the whole home. This project is designed to be part of a sustainable and transferable approach to water and sewerinfrastructure planning. Durham has plans to use it to reduce the environmental and economicburden of future infrastructure growth. The devices to be used to achieve this will increase newhome efficiencies through mandating their use via Sub-Division Agreements and RegionalStandards. This precedent has been set by using the MaP2 test results to define which toiletshomebuilders can use (via sub-division agreements) in two of Durham's eight local municipalities(the Townships of Uxbridge and Scugog). This project will provide the benefit/cost justificationfor some of the efficiency upgrades tested here.This approach is seen as on-going and incremental, as more efficient technologies emerge, theywill be incorporated into these Agreements and Standards. Includes table.
