SOLAR HEAT

Glass South Face – the entire front face opens.  Each room is glazed with operable windows for ventilation which sit over the top of trifolding doors. The back skylights and air vents are triple glazed poly carbonate and all vents are gravity operated using yatching cleats. Heavy curtains are used to reduce night time heat loss and a thermal drop down blind is used in the kitchen.

Solar Hot Water – a very large array is installed for heating water directly from the sun.  This is mounted on the front of the building.  The system uses black silicon tubing to carry the hotwater and a covering of glass tiles fitted to roofing bars.  The result is 11m2 of roof which harvests hot water free from the sun. Key to the design is the very large domestic solar hot water tank.  At 1000 litres, the tank is 5 many times bigger than a conventional tank – storing plenty of hot water during sunny days, and keeping a supply for cloudy days.

DRY COMPOST TOILET

Grey Water and Toilet – we recycle all ‘grey‘ water (water from washing) through a primary straw filter (grease trap), then through a series of reed beds, for final use in watering the gardens.  To ensure no water pollution is created by the groundhouse and to return nutrients to the land, we have fitted a dry toilet from Separret  in Sweden.  This separates urine which enters the grey water system and keeps solids dry and odour free until the collecting chamber needs emptying (around 2 weeks).  This is transfered to the toilet composter outside the building.  All plumbing is conventional in the groundhouse, and blank pipe runs are fitted for installation of a fosse septique.
