This house is totally electric. Lark Rise is perhaps the most advanced and highest performing passive house in the UK. It has been designed to produce two and a half times more energy than it consumes.
Crucially, because it is a passive house, even its winter power demand is small. With the addition of a 12kWp photovoltaic array to harvest solar energy, along with 12kWh of battery storage, this home is almost completely power independent and even in the most extreme winter conditions has a peak power demand from the grid by 80 % smaller than an ordinary home Lark Rise has been designed to show how the 'Smart Energy Revolution' has the potential to allow the UK to be powered by renewable energy rather than fossil fuel. You can see the detail of the reports and energy measures at https://www.bere.co.uk/architecture/lark-rise/
If the implementation of this concept were expanded, money spent on new and modernized buildings like this has the ability to reduce peak energy demand nationwide. If we can reduce peak energy demand, then we can reduce the need for new power plants, and the many billions of pounds saved in the construction, operation, fueling and eventually decommissioning of each power plant can instead create and convert more buildings like this, thus yielding more savings in power plant spending - a really healthy feedback loop.
This building is designed as a prototype for a type of building that will allow the UK to be self-sufficient in renewable energy; and therefore independent of energy. Their demand is so small that if all of our buildings were built or modernized to function in this way, renewable energy produced at home would easily supply all of the UK's needs, all the time.
This concept is being tested and advanced by us in a building commissioned by Cambridge Building's renowned physical and environmental engineer, Max Fordham.
It will also be the subject of a major book Max is currently working on, showing how the mathematics of the concept is completely workable and pointing out that it is better that we as a nation get on with the job.
