Berkeley Homes Case study
PDF | 544.81KB
A UK Pension Scheme established a collaborative development partnership with Berkeley Homes to construct two multi-storey residential buildings, providing a total of 249 private rental units. The development is located at a former retail park site on St Albans Road in Watford. JLL oversees asset delivery on behalf of the UK Pension Scheme.
Daikin’s Ambient Loop heat pump solution delivers high-efficiency, low carbon hot water, heating and cooling
The UK Pension Scheme is committed to leading the way in delivering world-class sustainability in its developments, to minimise the carbon footprint of its assets and to create genuinely sustainable living spaces where residents and communities can flourish.
The original development proposals, designed to comply with planning permissions, were based on an all-electric system for heating and hot water generation. BWP and JLL engaged jointly with Berkeley Homes to explore new highly sustainable and low-carbon technologies to provide the heating, cooling and hot water delivery to the development.
Air Cool Engineering Service & Maintenance (ACE) was approached by JLL and Berkeley Homes during the first week of the Covid pandemic to discuss The Exchange project. Having a long association with Daikin, ACE’s Kevin McLeod proposed a mix of multi-scroll Applied air source heat pumps combined with Altherma water source (WS ) heat pumps. This Applied and Residential product combination helps tenants live more sustainably and saves energy.
Multi-storey solution
Set in 1.6 acres of green space, The Exchange takes inspiration from the area’s printing and paper industry heritage. Each studio or apartment is equipped with its own Altherma WS heat pump providing heating, cooling and domestic hot water.
The ambient loop system will minimise heat loss throughout the building, keeping running costs low

Heating, cooling and domestic hot water on tap
The Central Water Loop will prevent the communal areas and corridors overheating, maintaining a temperature of around 23ºC, as water is circulated from the heat pumps on the roof at an ambient temperature. The Altherma WS units allow for each property occupant to manage the heating, cooling and domestic hot water to meet their individual requirements via their own metered electricity supply.
