Air source solution for Carus House, Clydebank
When Speyroc approached Ecoliving to provide a 12,500sq.ft, 3 storey, new-build office complex with a renewable heating solution, a ground source heat pump with boreholes was the favoured option as there was not sufficient land for horizontal ground loops.
The Carus House site in Clydebank is close to the River Clyde and a test borehole confirmed that there were 55+ metres of sediment overburden which would have to be cased. The cost of this pushed a ground source solution beyond the budget. The alternative solution proposed by Ecoliving was outdoor air to water heat pumps feeding the 3 floors with underfloor heating resulting in 5 units being installed together, outside the building.
The building design achieved a very good BREEAM rating, by maximising natural daylight and ventilation resulting in an anticipated annual heating demand of 171,272kWh/year.
The installation of 5 NIBE Fighter 2020-14kW units, by Speyroc, have resulted in an anticipated annual Energy Saving of over 70% (125,433kwh/year).
The project was completed in 2007.
