The project involved the complete refurbishment of the existing energy hungry 1960 dwelling. The existing property was clad in a completed insulated jacket and clad in sweet chestnut timber cladding. The interior were constructed from recylcled / salvaged materials. The house originally relied on oil to fire its boiler. This was replaced this high-energy system with a ’carbon neutral’ biomass boiler firing the hot water and central heating system (under floor heating to the ground floor and radiators upstairs). This system is supplemented by a 4msq array of solar thermal panels on the south facing roof. The boiler is predicted to be required only for about three months a year. The external fabric is so well sealed (tested at only 5 air changes per hour), and insulted that the house can rely on heat given off by the occupants, fittings, solar gain etc to keep it comfortable for most of the year.
From an energy point of view the resultant house performs to ’Level 5’ of the Code for Sustainable Homes – an amazing achievement for an average 1960’s dwelling.
