DISCOVER DISTRICT COOLING AND COMBINE WITH URBAN ECOLOGY
AN ENVIRONMENT-FRIENDLY AIR-CONDITIONING SOLUTION IN THE HEART OF THE CITY Te distrit ooling network: environment-friendly energy effiieny for te ity Far more tan a omfort feature, air-onditioning in buildings as beome an urban development issue. In addition to limate ange and urban growt, anges in ariteture and regulations are leading to new limate management metods and energy effiieny requirements in buildings. Distrit ooling is an essentiel energy for te sustainable ity. Te distrit ooling network is a olletive solution, wi intelligently meets te air-onditioning needs of dense urban environments beause of its strengts in terms of effiieny. Energy effiieny: te energy onsumed to produe illed water is signifiantly lower. Environmental effiieny: te loal natural resoures available are used. Sared and virtuous effiieny: by omparison wit an equivalent pool of stand-alone air-onditioning units, all te drawbaks (environmental, ealt, aestetis) are minimized. Disover te distrit ooling network and ombine effiieny wit urban eology. CLIMESPACE IS A GDF SUE CENTRE OF EXPERTISE FOR DISTRICT COOLING NETWORKS A pioneer and international leader in distrit ooling networks, CLIMESPACE (a subsidiary of Cofely-GDF SUE Energy Servies) is operating and developing a network in Paris tat is one of te largest in te world and te largest in Europe: 7 prodution sites and 3 energy storage sites, delivering almost 400 GW per annum of ooling to over 500 buildings, via a network of 70 kilometres. CLIMESPACE is ertified ISO 14001 (Environment) and OHSAS 18001 (Healt and Safety). As a entre of expertise witin te GDF SUE Group, CLIMESPACE brings its know-ow to distrit ooling system projets all over te world. 50% improvement in energy effiieny wit te Paris distrit ooling network Meeting ooling needs in a dense urban environment 1

COOLING IS AN ESSENTIAL URBAN ENERGY Cooling is a key energy allenge for wellbeing in te ity Cities are plaes were eat onentrates, so te problem to be solved is ow to meet te ity s air-onditioning requirements wit systems tat are environmentally-friendly, tenially effiient and in te olletive interest. 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 2020. Soure: European Union Sustainable Energy Week, 2009. 50% 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
Te distrit ooling network: a naturally effiient solution op * OF DIFFERENT COOLING SYSTEMS Energy savings, use of loal natural resoures, flexibility and seurity: te distrit ooling network offers many advantages ompared to stand-alone air-onditioning systems.

Firstly, it redues te use of illed water prodution maines during onsumption peaks or daily or seasonal igs. Seondly, it assures te ontinuity of te ooling supply even wen prodution plants are down. AUTOMATED ENERGY TRANSFER STATION It intelligently transfers ooling from te primary network to te seondary network of ea building onneted. It is far more ompat tan a standalone air-onditioning unit and frees up valuable spae. CONTROL ROOM Te ontrol room ensures 24/7 monitoring of prodution plants and energy transfer stations and remote ontrol of all distrit ooling network failities to optimize teir operation in real time. PRODUCTION PLANT It ouses te eletri-powered prodution failities tat produe old in te form of illed water (between 1 and 5 C) wit te best possible energy effiieny. Te eat released by te prodution equipment an be evauated via dry or wet ooling towers, or wen te loal situation permits, via systems using surfae aquati resoures (3 CLIMESPACE sites in Paris use water from te Seine in tis way).
