FACT SHEET Espoo Mall - Helsinki Reduction in Cooling Energy achieved . Less Chiller running Hours . Reduction in Heating Energy. Carbon reduction achieved. Over 70% Energy recovery Summer & winter with no cross contamination. Competition for business within the retail sector has recently increased sharply, placing increased pressure on businesses to drive-down costs in order to maintain profit margins. There is increasing pressure on retailers to meet targets to reduce their CO2 emissions. One obvious answer for both these issues is the reduction of energy consumption by applying modern sustainable technologies The solution was found by using FlaktWoods Econet®system combined with eac’s unique Aquacool ® Recovery Package. The advantage of Econet is that it combines all energy functions, recovery, heating and cooling are integrated into one package. Combined with Aquacool recovery system the resultant increased efficiency in heat transfer means far lower hot water temperatures (40/30˚C ) and far higher chilled water temperatures (14/18˚C) can be utilised. FACT SHEET Espoo Mall - Helsinki Design & Performance data : Summer Design Load was based on 30˚C 50% RH with a supply temperature of 16˚C.Winter -25˚C The Espoo Shopping Centre located in Helsinki has been rebuilt and expanded four times. Today the centre has 12,000m² of area occupied by a combined grocery/department store, a bank, a liquor store, video boutique and a shoe repair shop. About 200 persons work in the building which can have up to 12,000 visitors on a busy day. A pleasant & comfortable indoor climate is provided by a Econet Recovery system in which the indoor temperature never rises above 24˚c even when the outdoor temperature is as high as 30˚c. Additional benefits of Econet are Shorter air handling units, due to no need for additional heating and cooling coil.  Possibility of no mechanical cooling dependant on building design. Further capital cost and energy savings due smaller Boiler, Chiller, Pumps, pipework etc. Can be used with ground source heat pumps due to higher Chilled water and lower hot water temperatures'.
