Natural Resources Canada – Community Energy Systems B.3.1 Designing efficiency programs B.3.1.1 Municipal facilities (See retrofitting institutional buildings.) - Case study: Regina, SK The City of Regina has undertaken a number of initiatives to protect the climate and reduce energy consumption, making it a Canadian leader in this area. • Improving building energy efficiency (including sports facilities) and electrical system enhancements have reduced greenhouse gas emissions by 1,656 tonnes per year. • Street lighting conversion to efficient, cost-effective, high-pressure sodium lights, have yielded a greenhouse gas emissions reduction of 5,182 tonnes per year. • Changes to water supply systems in the form of pipeline twinning, variablespeed pumps, operational efficiencies and a water efficiency improvement program have cut 3,898 tonnes of greenhouse gas emissions per year. • Sewer and wastewater system improvements have provided annual emission reductions of 2,917 tonnes of greenhouse gas emissions. • The deployment of 79 natural gas vehicles in Regina's civic fleet -- including fleet vehicles for transit and public works -- are reducing greenhouse gas emissions across the city. Natural gas vehicles emit 26 per cent fewer greenhouse gas emissions at the tailpipe than the same vehicles that run on regular gasoline. Previously, the conversion of 60 civic vehicles to natural gas, and the installation of related fueling facilities, had been projected to reduce greenhouse gas emissions by 250 tonnes per year and save about $80,000 annually. • It also participated in the annual Commuter Challenge events, and encouraging municipal employees to car-pool as a way to make fewer vehicle trips.

Comprehensive GHG Emissions Reductions: Regina, Saskatchewan http://www.climatechangesolutions.com/municipal/buildings/stories/regina.shtml?o=bldgs&r=st ories - Case study: Portland Oregon, USA In 1991, the City of Portland developed an initiative, called the City Energy Challenge to reduce its annual energy bill in municipal buildings by 10 per cent over five years. The City succeeded in reducing its $8.8 million (US) annual energy bill by over $1 million (US) through efficiency and conservation measures, and in 2001 set a target for $1.5 million (US) annual savings. • 68,260 million BTUs (British thermal units) are saved every year.

Natural Resources Canada – Community Energy Systems • Through the Green Power purchase program negotiated with Portland General Electric, a minimum of 5 per cent of power supplied by Portland General Electric will be from wind power. • Wind power delivers about 2.25 million kilowatt-hours a year, and will result in net savings of $175,000 (US) annually. • By reducing demand for coal and hydroelectric power, the Green Power purchase will reduce CO2 emissions by more than 4,500 metric tons over five years through reduced demand for coal. • Energy savings from the program have reduced pressure on the US’s Northwest hydro system and endangered salmon runs.

The quantified annual benefits from the actions by the 80 award-winning businesses from '93 to '03 are significant. • Energy is saved in the following ways: 48.2 million kilowatt hours of electricity; 6.8 million therms of natural gas; and, 993,000 gallons (4.5 million litres) of gasoline. • Energy required to treat water is reduced because 868 million gallons, (3.9 billion litres) are saved. • Solid waste is reduced by 71,000 tons (72,136 metric tones), reducing impact on landfills. • Carbon dioxide (CO2) emissions are reduced by 112,700 tons (113,792 metric tonnes). • Cost savings are $13.2 million (US). Winnipeg, Manitoba also worked with the Portland Energy Office to develop a BEST program. Draft 4/11/2005 93
