This case study details the G-Core Limited team’s involvement in the £75 million project to deliver a new building at the Scottish Crime Campus, Gartcosh.

The development incorporated a Ground Source Heat Pump system (GSHP) to provide both Megawatt capacity space heating, cooling and simultaneous heating and cooling to the building in order to achieve the current and future operational requirements of the Crime Campus.  The main building consists of a central atrium with transepts, consisting of offices, forensic laboratories and support facilities.  The development is fully operational and accommodates 1100 people.

The team designed and installed one of the largest borehole Ground Energy Collector (GEC) consisting of 53 No. borehole heat exchangers, each to a nominal depth of 150m below ground level.  The GEC was coupled to a multiple Megawatt capacity Heat Pump system to provide high efficiency simultaneous heating and cooling.

The design of the GSHP system design was based on the Employer’s requirement to comply with local planning stipulations, to make large CO2 and operational cost savings and to provide for the heating and cooling needs of the various facilities within the building.  The design took into account the geological and hydro-geological conditions underlying the site, the heat extraction and dissipation capacity of the ground and annual heating, cooling and simultaneous load profile of the proposed building.

The GEC design was validated using a Thermal Response Test, which was completed on the first Borehole Heat Exchanger (BHE).  This ensured the final GEC model and design was correct to provide longevity of GEC over the 50 year lifetime of the GSHP system.

The GEC was coupled to two Climaveneta NECS WQ1004 simultaneous heat pump to provide peak heat output of 800kW, 1.113MW peak cooling and 2.107MW simultaneous heating and cooling.
