With our partnership freshly agreed with River Cottage, the Good Energy team – Katie, Sophy and I -- went down to River Cottage HQ to see how we can help River Cottage improve its sustainability. We were met by Stewart Dodd, the River Cottage architect who’s helped turn the derelict farm into the living, breathing hive of activity that you find at RCHQ today. Stewart’s already done some fantastic work on making RCHQ more sustainable, and we’ll be working together to build on that in the future. You can read Satellite Architects’ blogs on sustainable architecture practice here.
Walking down the hill to the farm, Stewart pointed out the artesian well that produces 7000 litres a day of fresh drinking water that bubbles naturally to the surface. A solar-powered pump carries the water to a storage tank up the hill to provide the necessary water pressure.
In the courtyard Stewart showed us the biomass boiler that provides much of the heating and hot water for RCHQ. The boiler is hooked up to the kitchen’s hot water system and the central heating system for the farmhouse and the Threshing barn – their events venue. The boiler uses about 40 tonnes of dried split logs that RC sources from Forestry Commission woodland less than half a mile away – a great use of a ‘Carbon Neutral’ local resource (wood absorbs as much C02 when it grows as is released when it’s burned).
While head chef Gill and his team were busy in the kitchens cooking up fresh mackerel for our lunch, Stewart led us into the Threshing barn to tell us about the high levels of insulation underfloor and in the roof that help to improve the thermal performance of the building. The original solid stone walls lose heat pretty fast so it helps to pack in as much insulation where it can be used.
And then, back outside in the sunshine, Stuart showed us RCs green water treatment system. All the waste water at River Cottage – the ‘grey’ water from the kitchens and the ‘brown’ water from the loos is channeled through a reed bed system. These hardy plants feed on all the impurities in the waste water, which supports their growth and once processed, the water is crystal clear and fit to pass back into the water table.
So, River Cottage is off-grid for their water supply, supported by a sustainable well-supplied source. Much of their heating is provided by local wood, a sustainable carbon neutral fuel. Their waste water is processed in the most natural way possible and delivered back to the environment as clean as it started. They’re generating their own green electricity and any extra they need they buy from us, 100% RENEWABLE!
We were beginning to scratch our heads as to how we could help. While they’ve made some very impressive steps to cut their carbon footprint, there’s still room for further improvement. As always, the first step is to reduce your energy consumption. Some of RC’s fridges look like they might be sucking up quite a lot of energy and their offices are a temporary building that is heated by electricity (not a good fuel for heating) and the insulation can be improved quite considerably.
And the most important element at River Cottage – The Cooking – relies on propane gas – a fossil fuel.
So, where can we help? Well, we reckon you should always start with measurement. Once you know how much energy you’re using and how you’re using it, you can begin to look at how you can reduce your energy consumption and what other sources of energy you can consider switching to, including generating your own energy.
Once we’ve measured RC’s energy use, we’ll think about solutions to help them use less. Some new fridges will be a good idea and lots of simple but effective energy-saving measures too. And then, what about the energy they could generate? Will solar power work well at RC? Is another wind turbine a good idea? What about the cooking gas they use? Can we help them find a fuel the chefs will be happy with that’s also sustainable?
We’ll keep you posted.
