Zero Energy Buildings
Part of the programme involved the construction of a new key worker housing development including 12 “zed” housing units (zero energy) which went on to win Low Energy Building of the Year Award in 2006.
The energy bills (around £100 per annum per household) are the result of adopting a super-insulated and airtight building with zero carbon space heating standards. All living rooms face due south and have large windows and direct access to attractive south-facing winter gardens and balconies.
To achieve zero energy in these new build properties the ingredients needed to be exact, so as well as super efficient heating systems, insulation needed to play an important part in the build and one of the key factors in this was obviously the windows.
The products chosen were Tilt and Turn timber windows and timber Sliding Patio Doors and were designed with top specification 24mm glazing systems to give optimal energy performance, without which, the zero energy rating would not have been achieved.
With housing associations looking to provide more and more energy efficient housing, using less carbon in the running of the homes is still important but it is equally important to choose materials to build these properties which are environmentally friendly and offer sustainability. FSC Chain of Custody timber. A+ rating in BRE's Green Guide to Specification. Triple-glazed windows down to Passivhaus, 0.8 whole window u-values.
