We’re delighted to play a role in this project, contributing to feasibility and installation planning, advising on additional decarbonisation strategies to maximise efficiency, and supporting upgrades to the Theatre’s existing systems —one step closer to a sustainable future! 👏 #Sustainability #Decarbonisation #Innovation #HexagonTheatre #theatre
The Hexagon could be the first theatre in the country to be heated by using naturally occurring warm water from underground. Ground source heat pumps work by harnessing heat from water which flows naturally underground. This is pumped to the surface where heat is extracted using a heat pump and transferred for use in a building. The cooler water is then returned underground. It is like a fridge in reverse. This form of renewable energy is one of the sustainable initiatives being used in the redevelopment of The Hexagon. The old inefficient high carbon gas boilers are set to be removed and the ground source heat pumps will reduce the carbon emissions of the theatre. This method is a sustainable and low carbon way of heating the building which fits the Council’s ambition to create a carbon free Reading by 2030. Over the summer contractors Drift Services Group conducted an exploration of the Queen’s Walk site to see whether the area would be suitable for extracting the water found in the chalk aquifer running under the town. Two 120m deep, 35cm wide boreholes have been drilled and tests were conducted to see if the flow and the temperature of the water are sufficient to support the heating needs of The Hexagon complex. Results show that 15 litres of water per second can be extracted and raised to the surface to a heat pump which will extract the heat and use it in the building before replacing it at a lower temperature further downstream. The geology of the area means that water can flow through the fractures in the chalk, making it particularly suitable for the new way of heating buildings. The water levels returned quickly after extraction throughout the testing process meaning it will have minimal impact on the surrounding area, which forms an important part of the test. The Council has now applied to the Environment Agency for a licence to use the boreholes for this purpose. The heat pump system will be funded through the Public Sector Decarbonisation Scheme through Salix who work on behalf of the Department for Energy Security and Net Zero.
