A total of 900 flats will be constructed and these buildings will be used for short term thermal storage; this means they will be used to store heat when demand is low and release heat back into the building when heat demand is high. By using these buildings as thermal stores you are able to reduce the size of the energy production peaks in the district heating production system whilst still meeting the overall heat demand on the network at peak times. This reduction in energy production will lead to a decrease in the use of fossil fuels and consequently the amount of CO2 emissions produced. The materials in the walls, ceilings and floors have energy storage capacity and are charged with energy during the hours of low consumption or demand by marginally increasing the indoor temperature. The accumulated energy that is stored in the buildings is then used to maintain the level of the indoor temperature during the hours when consumption is traditionally higher by releasing that energy back into the building as heat. These temperature changes will not be noticed by the residents but will allow heat production to be kept at a lower level during peak hours.
