Orme Square – London

Consultant: Hoare Lea
Main Contractor: Sizebreed

The Project

Orme square was a refurbishment of a 13,000sqft Grade 2 listed building and to meet with all the regulations imposed, a ground source heat pump system was untilised to provide simultaneous heating and cooling using water cooled fan coils feeding atriums and local areas. As well as proving underfloor heating and low temperature hot water at 45 deg C enabling a COP of 4.2 to be obtained.

The heating and cooling load 70kw was achieved by installing a vertical closed loop bore hole system drilled to a depth of 130m. Two Aermec heat pumps connected to a sliding header arrangement made the simultaneous heating and cooing arrangement possible.

Ikea – Exeter

Ikea Exeter was a fast track project comprising of 16 bore holes drilled to a depth of 200m. The simultaneous heating and cooling system was achieved by 3 off 65kw heat pumps with a supplement dry air cooler meeting the peak loads.

Fleet House – Hampstead

Consultant: Ritchie Daffin
Main Contractor: Harris Calnan

The Project

Fleet house is a set in picturesque Hampstead, a stones throw away from where Constable spent 2 years painting the surrounding views. The imposing house has many architectural features without impacting on the surrounding landscape.

The heating load 15kw was achieved by installing a vertical closed loop bore hole system to a Viessmann heat pump and solar thermal array to maximize the efficiency to provide hot water and underfloor heating.

The system comprises of a Thermal store which stores heat produced via the solar panels and is then topped up by the high efficient ground source heat pump producing COP’s of 4.3.

10 Fenchurch Avenue – London

Consultant: Waterman Gore
Main Contractor: Sir Robert McAlpine
M&E Contractor: M J Lonsdale

The Project

10 Fenchurch street is located in the heart of the City square mile, the new large office development has a closed loop ground source system installed to generate a simultaneous heating and cooling system.

The cooling load for the retail units is 260kW with a Heating demand of 200kW this is achieved by a closed loop system installed to a depth of over 260m, due to the small foot print of the building. The 17 bore holes were drilling within a 6 week program using a single drilling rig.

The ground source simultaneous heating and cooling is obtained using 3 – Aermec 4 pipe heat pump units achieving an overall COP of 6.5 when in heating and cooling mode.

23 Cavendish Close – London

Consultant: The KUT Partnership
Main Contractor: B&G Construction

The Project

Cavendish close located in St Johns wood underwent a transformation having a 2 floor basement installed at the front and the rear of the property, and then joined under the main building. The 230m deep bore holes were drilled prior to the digging out of the basements

The cooling and heating load for the residence 80kW was achieved by a closed loop system The ground source heat pumps simultaneous heating and cooling is obtained using 2 Mitsubishi VRF Simultaneous heating and cooling heat pumps coupled with Fan coils and a Mitsubishi AG200 centralized controller achieving an overall COP of 4.9

The total project duration was 24mths

3 Screen Cinema – Lewes

Consultant: S.G.A. Consultants
Main Contractor: R Durtnell & Sons

The Project

The 3 screen Cinema came about from a group of local residents passion for the arts and film industry , there goal to bring to the community innovative independent contemporary classic’s and world cinema productions making the venue prominent within the South East of England with special events, guest speakers, workshops and an educational facility.

The Cinema has a water cooled simultaneous cooling and heating system serving hot water, cooling, and heating from the 150kw heat Pump. 12—200m closed loop bore holes were installed and connected to the system.

The high efficiency of the simultaneous heat pump gives a COP of 6.5 when in heating and cooling mode.
