Lark Rise: the smart home which produces more energy than it uses lifestyle
Designed by the British architect, Justin Bere, under PassivHaus European standards, this 175m2 home located in Buckinghamshire complies with the ‘smart energy revolution’ standards.
Its photovoltaic panels allow this building to function as a real power plant because it generates twice the energy that is uses.
Located in county of Buckinghamshire in the UK, Lark Rise is one of the most efficient homes in Europe. This work overseen by Justin Bere from the Bere Architects Practice, is back in the news on this World Energy Efficiency Day.
For a ‘smart energy revolution’
Following the guidelines of the Smart Energy Revolution, which encourages all homes in the UK to be self-sufficient in renewable energy, this 175m2 building stands out because of its ecological character. In its roof, some large photovoltaic equipment that allows this house to produce twice as
much energy per year as it uses has been included. In percentage terms, this house needs 97% less energy from the British electricity grid.
Following the Passivhaus principles (passive house): optimal thermal insulation for outdoor walls, breakages of thermal bridges, mechanical ventilation with heat recovery and high-performance windows; its structure is totally electric and has a negative final energy demand of -6.16 MWh. “Lark Rise was designed to show how the Smart Energy Revolution can make the UK use renewable energy and be self-sufficient”, Bere Architects point out. As well as that, they argue that if this building is used as an example, it could reduce the maximum energy demand which, would mean an end to “the need for new power plants. These millions of pounds will allow us to save on building and fuel supply, which would lead to more buildings like this being created“.

The 2030 plan for Sustainable Development
Controlling energy consumption and implementing sustainable policies have become two key issues for the European Union. To achieve this, various initiatives have been launched by the European Commission, ranging from housing energy rehabilitation (representing around 40% of the EU’s energy demand), renewable energy programs and greater support for urban transport. An objective that is expected to be met in 2030, where it is expected to reduce energy consumption by up to 32.5% through the ELENA program (European Local Energy Assistance). A plan promoted by the European Investment Bank (EIB) to which the EU will allocate 97 million euros in order to increase the comfort of public and private buildings, along with reducing energy bills.
With this change of scenario, the Passivhaus Platform stands out, following the conditions established in the 2010/31 / EU European Directive on building energy efficiency. The PassivHaus program was created in Germany in 1988 by Professors Bo Adamson (Lund University, Sweden) and Wolfgang Feist (Institute of Housing and Environment) and it encourages reducing energy consumption by 70% when compared to other conventional buildings.
