Green houses
June 1st 2008 Windmill View in Illingworth,West
Yorkshire is a development of 82
properties by Bramall Construction,
Synergy, Pennine Housing 2000
and the Housing Corporation.Two
of the properties are the first
houses in the country to be built to
the recent Sustainable Code Level 4
– the Government eco-target for
new homes. Level 4 requirements
have been met by including solar
panels, 300mm filled cavity walls,
and improved U values on glazing,
doors and loft space. Also installed
are NIBE Heat Pumps to convert air
usually expelled in normal
ventilation, into energy for
domestic hot water and heating.
The NIBE Fighter 360P units take
air at ceiling level – warmed by the
heating system, home appliances
and residents' body heat– and
extract the energy via a heat
exchanger, expelling it into the
outside atmosphere close to 0°C.
The recovered heat is passed by an
indirect heating surface to a hot
water tank, double-jacketed so that
domestic hot water and radiators
can be heated at the same time. More articles from NIBE Energy Systems Ltd: |
