‘HOUSE AS POWER STATION’ LARK RISE, BUCKINGHAMSHIRE
An all-electric home that produces twice the energy it consumes, Lark Rise in the Chilterns won the Project of the Year – Residential category at this year’s CIBSE Building Performance Awards.
Designed by bere architects, the Passivhaus has a 12 kW rooftop solar PV array which enables it to import 97 per cent less energy from the electrical grid than the average UK house, and it exports 10 times as much as it takes. The judges said this scheme delivered “outstanding measured building performance, energy efficiency and reduced carbon emissions.” Run by the Chartered Institution of Building Services Engineers, the

Building Performance Awards win shows that “with two years’ close monitoring, Lark Rise can demonstrate that the design principles work in practice,” said CIBSE.
Lark Rise has been designed to show
how the ‘Smart Energy Revolution’ has the potential to enable the UK to be fuelled entirely by renewable energy. This ‘building as power station’ concept is intended to help the UK to be self-sufficient in cheap renewable energy, increasing energy security. This north-facing, all-electric building has a negative final energy demand of - 6.16 MWh. This converts to -35 kWh per square metre per year, so it can be regarded as a ‘mini power station’ for
the National Grid. The building’s designers suggest that the home is the most advanced, high performance house in the UK.
The CIBSE Building Performance
Awards recognise the people, products and projects that demonstrate engineering excellence in the built environment. They focus on “actual, measured performance outcomes, not just design intent or performance specifications,”said the organisation. Entries are open to anyone responsible for design, commissioning,
construction, installation and operation of low energy buildings as well as manufacturers working towards efficient energy consumption.
