Open house visits: more about the Peveril solar

Tina asked me to write a bit about one of the two houses that are on the visit of 16th September at 2pm or 3.30 pm. There is only a ten minute walk between the houses, so we have arranged is so that you can see one and then walk to the other.

The Peveril Solar house is Net-Zero due to an interesting combination of solar technologies - Photovoltaic, Surya Sunbox, Kingspan vacuum tubes, underfloor heating and a Ground source heat pump. During the visit, the way in which these interact will be explained. There are other energy saving things to see, such an an induction hob, light tube, voltage regulator, partial heat reclaim.
Net-zero means that its entire heating and hot water requirements are met by PV power generation, annually. Yes, is entirely solar heated the whole year round using electrical and thermal storage.

Another interesting thing is that a new house extension is being built, being a unique form of construction. The architect is adapting structural insulated timber panel construction but applying hand built methods that avoid thermal bridging, making it ultra insulated, but keeping the walls to half the thickness of a brick-block wall. The extension will include one of the first domestic installations in the UK of PV-Thermal combi panels, the PV providing off grid electricity and the thermal being used to charge the borehole 16 storeys deep under the house.
