Nature Reserve Visitor Centre Case Study - Nottingham
Attenborough Nature Reserve is situated in the Trent Valley on the south-western edge of Nottingham and consists of 240 acres of flooded gravel pits with associated marginal vegetation on a site of approximately 360 acres.

The Visitor Centre houses facilities including meeting rooms, education facilities, interactive displays, a nature shop, and a café. A key strategy was to design a building using renewable energy resources sufficient to meet its annual energy needs, thus achieving zero net greenhouse gas emissions.
The building envelope is super insulated, typically 300-350mm thick rockwool, and the high levels of insulation in the walls, floor and roof minimise heating requirements, resulting in an overall heat loss of only 15kW for the whole building.
A Thermia heat pump is installed to provide heating and hot water for the Centre by utilising energy from the lake. Additional heat is provided by roof mounted hot-water solar panels, and the heat from both sources is stored as hot water in an insulated thermal store. This supplies underfloor heating throughout the building and hot water to thekitchen, toilets and classroom.

Carbon Savings: ~225 Tonnes
Heat Collector: 2 x 200m Pond Loops
Heat Pump: Thermia Diplomat
Heat Distribution: System Wet Under Floor
Build Type: New
Property Size: 400m2
* Based on 25 years running costs compared with oil-fired boiler with 75% efficiency and annual servicing cost of £100. Electricity at 7p/kWh and oil at 3p/kWh - not including replacement boiler.
Offices & Industrial Unit Case Study - Grimsby
Elecref Ltd makes control systems for the food industry. They built their new premises in 2003 after twenty years in their previous location. All of the heating and domestic hot water in the new building is now provided by the heat pump system.

Space heating is provided within the offices and assembly areas using under floor heating. Passive and active cooling is also provided by the heat pump using a ducted air system. The underground heat collector is a horizontal slinky based system.
Lifetime Savings: ~£35,000*
Carbon Savings: ~300 Tonnes
Heat Collector: Horizontal Closed Loop
Heat Pump: Eko
Heat Distribution: System Wet Under Floor
Build Type: New
Property Size: 400m2
* Based on 25 years running costs compared with oil-fired boiler with 75% efficiency and annual servicing cost of £100. Electricity at 7p/kWh and oil at 3p/kWh - not including replacement boiler.
Housing Association Case Study - Stornoway, Isle of Lewis Scotland
Six new houses built for New Valley Housing Association have ground source heat pumps installed. The heat pumps provide all of the space heating and domestic hot water requirements for the occupants. Each house has either 75m or 100m of borehole drilled.

The heat distribution system is underfloor on both floors with traditional slab construction downstairs and 'Lewis' plates with a cement screed upstairs. This gives a reasonable thermal mass in the upper floors.
The heat pumps are Thermia Diplomat units that include a 150 litres mains pressure hot water tank. Space heating is controlled using weather compensation, which means the units are always 'scavenging' to keep the occupants warm at the lowest distribution temperature. This reduces energy costs and CO2 emissions. Running costs are estimated at £160 per year.
Heat Collector: Vertical Boreholes
Heat Pumps: Diplomat
Heat Distribution Systems: Under Floor
Domestic Hot Water: Integral 150 Litre Tanks
Build Type: New
Property Size: Various
* Based on 25 years running costs compared with oil-fired boiler with 75% efficiency and annual servicing cost of £100. Electricity at 7p/kWh and oil at 3p/kWh - not including replacement boiler.
Garden Centre Case Study - Nairn, Scotland
Broadley Garden Centre at Nairn near Inverness was designed and built by Innova House Ltd Innova House supply packaged timber frame systems that are energy efficient, low maintenance and built using non-toxic and recyclable materials. The natural compliment to this was to provide heating and hot water using renewable energy with one of our ground source heat pumps. |

Space heating at the garden centre is by an underfloor system and the domestic hot water uses a 500 litre mains pressure tank all fed from the heat pump system. The heat collector is a straight pipe closed loop based system installed under the garden centre's car park.
"Three quarters of the Garden Centre's energy consumption is solar energy taken from heat stored in the car park! This means that the garden centre has reduced its greenhouse gas polluting emissions by over 60% compared to a normal heating system."
Lifetime Savings: ~£39,400*
Carbon Savings: ~345 Tonnes
Heat Collector: Horizontal Ground Loops
Heat Pump: Thermia Robust
Heat Distribution System: Wet Underfloor
Domestic Hot Water: KBH 500 litres
Build Type: New
Property Size: 450m2
* Based on 25 years running costs compared with oil-fired boiler with 75% efficiency and annual servicing cost of £100. Electricity at 7p/kWh and oil at 3p/kWh - not including replacement boiler.
School Case Study - Wormholt Park Primary School, London
One of our systems has been installed to heat a new teaching space at this inner city school. Domestic hot water is also supplied from an integral 150 litres. The building is timber framed with cedar on plywood external cladding and is extremely well insulated. Our heat pump was a natural addition to compliment its already 'green' credentials. |

A horizontal ground loop is installed to collect the heat and under floor is used for the space heating.
Lifetime Savings: ~£12,000*
Carbon Savings: ~90 Tonnes
Heat Collector: Horizontal Ground Loops s
Heat Pump: Diplomat
Heat Distribution System: Under Floor
Domestic Hot Water: Integral 150 Litres

* Based on 25 years running costs compared with oil-fired boiler with 75% efficiency and annual servicing cost of £100. Electricity at 7p/kWh and oil at 3p/kWh - not including replacement boiler.
Health Centre Case Study - Family Cancer Information & Support Centre, Norwich
This innovative circular building, part of Norfolk & Norwich University Hospital, will be heated using one of our systems, which will also supply the domestic hot water. Because of limited space on site to install horizontal ground loops and restricted space in the plant room, our new Atria air sourced system was the ideal choice. |

Commercial Barn Complex - St Ingunger, Cornwall
This is a fine example of a large barn complex and the use of ground source heat pumps. The site has a large adjacent field in which the ground loops are installed. A number of barns are fed from a central unit to create a mini district-heating scheme. |
