Colt has successfully linked its WRF air-conditioning system, Caloris, with Ground Source Heat Pump (GSHP) technology, to provide an energy efficient HVAC solution for the Hatchcroft building, a new, multi-million pound teaching and research facility, for Middlesex University.

The building, which has a capacity of 1,100 staff and students, has been designed to be both adaptable and sustainable, accommodating laboratories for Biomedical teaching and research, classrooms and associated facilities for Psychology, Computing and Sports Sciences.


	A new multi-million pound teaching and research building has been constructed for Middlesex University

Built in place of six, now demolished, buildings, the new development has achieved a 12% reduction in CO2 emissions. Colt Caloris linked to GSHP was chosen as an energy efficient solution to assist in this reduction, as well as generally contributing to the University's ambition of achieving an "Excellent" BREEAM rating.



	For the air conditioning of this building Colt has provided a complete package of 59 Caloris WRF units			The Caloris WRF indoor units connected to a ground source heat pump system

Throughout the building, 59 Caloris indoor units have been installed connected to a vertical, closed loop borehole, GSHP system. Taking up an area of approximately 1,400 m², 55 boreholes have been drilled to an approximate depth of 60m, accommodating the GSHP's 32mm coil arrangement. The resultant HVAC solution can provide a capacity of up to 235 kW gross peak heating load and 190 kW net peak cooling load.

Colt was awarded this contract due to its ability to help integrate the complete package of works, from the design and installation of the GSHP system, to providing the link between the ground and the indoor Caloris WRF units.
