Example: Commercial Buildings

Kensa has calculated costed examples for ground source heat pumps in large and medium-sized commercial buildings, to illustrate the costs and savings using both self-financed and funded split ownership models, compared to LPG alternatives.

Benefits of a cascaded system

Kensa heat pumps can be configured in a modular ‘cascaded’ configuration, providing a wealth of benefits for buildings with high heat demands.

cascaded ground source heat pump system architecture can be effectively used to meet a high heat load, adjust to seasonal variations, maximise efficiencies of multiple temperature zones, add redundancy, and reduce overheating.

One of the many benefits of a cascaded ground source heat pump system is the ability to flex between periods of minimum and maximum heat demand; for example during the spring and summer when the need for heat is lower, only one heat pump need be in operation, with subsequent heat pumps coming into operation as the heating season progresses.

Costed Example: Large Commercial Building

This ground source heat pump costed example features a large single commercial building with a 515,000kWh annual space heating demand.

Kensa has calculated this example will require a 4000m2 area for the borehole ground array infrastructure.

Costed Example: Commercial Building

This ground source heat pump costed example features a smaller single commercial building with a 102,500kWh annual space heating demand.

Kensa has calculated this example will require a 500m2 area for the borehole ground array infrastructure.
