Solar energy is used to supplement energy in district heating systems that supply an entire residential area with heat. • Saro hopes to be able to heat in winter with the summer sun, and collect more than two-thirds of total energy needs for space and water heating from solar facilities.

Växjö was committed to reducing CO2 emissions in the community by 50 per cent. The new community heating plant, fuelled by wood chips, was opened in 1997. This and an older district heating plant, also fuelled by bioenergy, supply the city of Växjö with most of its thermal energy needs and much of its electricity requirements. Smaller district heating plants have been installed in three of the surrounding villages. The municipal housing company, Värendshus, has begun fitting new buildings with solar collectors. • Buses run on 50 per cent rape methyl ester (RME). • The municipal government has acquired both electric and ethanol-fuelled cars. • Seven major industrial companies and utilities have formed the Växjö Bioenergy Group and have undertaken to pursue the same targets as the municipality. This project was identified in 2000 by the UN as a Global Best Practice for Improving the Living Environment. Växjö is a partner in the European Commission’s CTO-campaign for 100 per cent renewable energy systems. For more information, contact Sarah Nilsson, City of Växjö, P.O.

<strong>Natural</strong> Resources Canada – Community Energy Systems generation. Partnering with Terasen Gas (formerly BC Gas), the Lonsdale Energy Corporation is connecting a series of cogeneration plants and new, primarily residential developments to form a single district energy system. • Reliance on gas and oil is reduced, thereby reducing CO2 emissions.

When software giant IBM consolidated its software research and development sector it chose to locate in Markham because the municipality offered a cost-effective energy supply. Markham District Energy Incorporated was established to provide IBM with district heating and cooling. The municipal government quickly realized that Markham District Energy offered more than stable pricing; it was an economic development magnet. Even before the IBM construction was complete, another hi-tech giant, Motorola, moved to the area; it has also been connected to district system. Recently, the condo developer Tridel agreed to link a condominium complex (slated for construction in 2004) to the district energy system. Markham’s city hall and surrounding municipal buildings are also to be linked to the system. For additional information, contact Bruce Ander, President, Markham District Energy Inc., Tel.: (905) 513-4164. - Case Study: Hamilton, ON The district energy system in Hamilton, Ontario produces both heat and electricity from a clean burning natural gas-fired reciprocating engine connected to a generator and three, gas-fired boilers. Compared to the typical 40 to 60% efficiency range for conventional installations, this combined heat and power technology produces energy at an overall efficiency rating approaching 80 per cent. The combined heat and power installation produces hot water that is distributed by an underground pipeline to 10 or 11 large buildings clustered on the west side of downtown including, City Hall, Copps Coliseum and the Hamilton-Wentworth District School Board, the Market Library, Hamilton Place, the Convention Centre, Board of Education, Art Gallery, Ellen Fairclough Building, and Sir John A. MacDonald High School. Besides thermal heat, the installation produces 3.3 megawatts of electricity, to be routed through the city's Central Utilities Plant. That is enough to supply city hall, the convention centre and other nearby buildings in the event of a long-term power disruption - the kind that ice storms can cause. The system is designed with backup Draft 4/11/2005 111
