Middlesex University Hatchcroft Building
Colt Installs WRF and GSHP package at 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.

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.

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.
