In tis ontext, te distrit ooling network is bot a present-day solution and a means to elp us prepare for te anges in urban limate requirements. A growing urban onentration Over alf of te world s population live in ities; tis figure will rise to 60% by 2030 *. As bot a strutural fat and a onsequene of tis, energy needs are onentrated in ities wi is were 75%* of te world s energy is onsumed. * Soure: UN An urban eat island effet Te majority of ities experiene a loalized rise in teir temperature due to te effet of an artifiial miro-limate aused by uman ativities (industry) and urban planning (dark and/or aspalted surfaes tat absorb more eat). How to ontrol tis eat island penomenon, wi affets te quality of life and te environment, is a major allenge for urban deision-makers. Distrit ooling tenology elps prevent te warming of te loal atmospere observed wit stand-alone air-onditioning units. KEY AIR-CONDITIONING FIGURES IN THE WORLD 10% of eletriity is used for air-onditioning in te world and 16% in te USA. Over 80% of business and institutional establisments ave air-onditioning in te USA and Japan. Less tan 40% of su establisments are air-onditioned in Europe, but tis figure is rising and migt rea 60% by Soure: European Union Sustainable Energy Week, % less CO 2 emissions wit te Paris distrit ooling network New demands for termal omfort As buildings beome better insulated, in aordane wit anges in termal regulations, te soures of internal eat in buildings (eating, omputers, ome automation) are inreasingly trapped inside. So te sare of air-onditioning in a building s total energy requirements is on te inrease, wi is wy it is important to develop effetive means to supply ooling in energy and environmental terms. Cooling is an essential element of sustainable urban development Te oie of a ooling metod is an issue of strategi importane in tis ontext for te sustainable ity. For loal autorities, te oie of distrit ooling reflets te desire to ontrol teir energy plans. Beause it is so effiient, te distrit ooling network effetively elps to aieve loal objetives for energy effiieny, lower CO 2 emissions and te use of loal renewable energy soures. 2 Understanding multiple allenges 3
