Meanwhile, our QS, Gavin, Jonathan and Jeremy from Shingler and myself have been meeting with renewable energy companies to confirm the technologies we will put into the building. Yesterday we met with Eco Living. Ground source heat had been a favourite, however our sandy soils at Fordhall, although great for out wintering our cattle, are not suitable for a Ground Source Heat pump as they do not hold enough embodied heat, which then reduces the efficiency of the system. The alternative may prove to be an Air Source Heat pump, but we will let you know as soon as decisions are made. Thought is also going into to PV cells for electricity generation, recovering warm air from the butchery refrigerators, and recovering warm moist air from within the building and converting that energy to fresh air to help keep the building warm (heat recovery system). There is a lot to think about. There are now many technologies available and we must be sure that we are investing our funds in the most sustainable and efficient system for Fordhall... perhaps we should see what our new apprentice builder thinks?
...watch this space.
