Calculations indicate that currently, the amount of heat wasted in Europe is enough to supply the heat demand of all bu P6 GLOBAL DISTRICT ENERGY CLIMATE AWARDS By Robin Wiltshire, Chairman of the Evaluation Panel and Chairman of the IEA Executive Committee for District Heating and Cooling INTRODUCTION TO THE GLOBAL DISTRICT ENERGY CLIMATE AWARDS It has been my privilege to Chair the Evaluation Panel for the Glob P7 FOR A CLEANER TARTU GLOBAL DISTRICT ENERGY CLIMATE FROM SOVIET TIME DISTRICT HEATING SYSTEM TO EFFICIENT DISTRICT HEATING AND COOLING SYSTEM IN TARTU, ESTONIA AWARDS By Margo Külaots, Chairman of the Board, Fortum Tartu Over the years, Tartus district heating and cooling system has undergon P8 In the areas defined as district heating zones, all new buildings and those undergoing a major renovation must be connected to the network. These areas are readjusted when the master plan is updated. The current district heating areas were defined in 2017, following a negotiation process between P9 Some years ago Fortum Tartu identified four areas for district cooling development in the city. The first cooling customer for Fortum Tartu was the Estonian National Museum. Fortum Tartu made a tailor made local cooling and DH solution for this nationally very important building. First DC custom P10 GLOBAL DISTRICT ENERGY CLIMATE AWARDS By SIA Salaspils Siltums, Latvia SALASPILS SILTUMS FROM POST-SOVIET BOILER STATION TO A MODERN ENTERPRISE Heating is an important component of quality of life for the residents of Latvia as the average outdoor air temperature is 2.1 oC during the heatin P11 In order to ensure efficient production and reduce gas consumption, three high-efficiency gas-water boilers were installed replacing the outdated Soviet-era equipment. The gas boiler station before and after the upgrade Fuel diversification From 2008, the company was purchasing heat from the P12 The customer service levels are worth a special mention. Customers of Salaspils Siltums can choose when to start the heating season. Using a remote data reading system, an employee of the company continuously monitors the heating energy consumption and advises the consumers on more efficient us P13 LUSAIL CITY DISTRICT COOLING SYSTEM DOHA, QATAR GLOBAL DISTRICT ENERGY CLIMATE AWARDS By Vinod Kesavannair, Engineering Manager, Marafeq Qatar LLC One of the largest district cooling systems in the world when completed, Lusail City District Cooling System, being developed to the north of D P14 NETWORK DESIGN Marafeq Qatar designed the distribution network of approx. 170 km with strategically placed loops and isolation valves. To assure high quality, Marafeq Qatar selected an all welded pre-insulated steel piping system with integrated leak detection system; all certified in accordanc P15 INNOVATION AND APPROACH The Lusail City project is so huge that each of the 19 districts or each of the four district cooling plants is like a project in itself. And within the overall scheme, Marafeq Qatar prepared plans for temporary, modular, and permanent chiller plants to serve the various P16 By Mag.

The overall entrepreneurial risk of a project can be managed by avoiding certain risks entirely (e.g. by only realising projects with positive seismic resul P22 In these countries in particular options to convert ageing fossilfuelled district heating networks to geothermal energy abound. This would allow communities to futureproof their heating systems by making then more consumer and environmentally friendly as well as independent from fossil fuel imp P23 Even though geothermal projects are economically viable without financial support, such assistance can prove very valuable in furthering development faster and allowing for cooperation and knowledge exchange between different companies in the geothermal sector, thereby facilitating the process P24 By Michael Noer-Hvarre, CMO, Drone Systems ApS, Sune Yde Nielsen, CTO, Drone Systems ApS, Henrik Grosen, CEO, Drone Systems ApS SAVING TIME AND MONEY: MAPPING DISTRICT HEATING NETWORKS FROM DRONES This has proved sufficient for digging directly to leaks or pipes with faulty insulation.
