The Order relates to obligations on certain suppliers in the period from 1 April 2005 until 31 March 2008 and forms part of the Government's Climate Change Program.
The Order sets an overall target for improvements in energy efficiency. Ofgem is required to apportion an overall target to gas and electricity supplies. At least 50% of the total improvements must be in relation to there domestic consumers.
Quantifying improvements in energy efficiency: - Ofgem will use 3 steps to determine the improvement in energy efficiency by firstly calculating the annual energy saving. Secondly the amount will be fuel-standardised. Thirdly, the resulting amount will be lifetime-discounted. One example is comparing the energy required to be consumed to heat a home to the same level before and after insulation has been installed.
Ofgem expects suppliers to most commonly promote the energy efficiency actions into insulation, lighting, heating, appliances and CHP
MANY PEOPLE DO NOT REALISE THAT GRANTS ARE AVAILABLE TO IMPLEMENT THESE MEASURES. UK HOME INSULATION are one company providing a central point of contact for the general public throughout the uk. They work with reputable insulation surveyors and installers who are already grant approved.
Energy savings for loft insulation actions have been calculated on a property type basis using The Building Research Establishment Domestic Energy Model (BREDEM). Energy savings for installations of, or up to 200mm, 250mm or 270mm of loft insulation are included and available on the EEC Scheme Spreadsheet.
The lifetime of loft insulation is estimated to be 30 years.
Loft insulation should be installed to a depth of 270mm. When insulation lofts the loft hatches must be insulated and draught sealed. There are two British Standards relevant to the installation of loft insulation. These are:
BS 5803 Part 1: and BS 5803 Part 5.
There are two Good Practice Guides relating to best practice when installing loft insulation. These are "Energy efficiency refurbishment of existing housing" and "Refurbishment site guidance for solid walled houses-roofs" The two Good Practice Guides also refer to best practice methods to avoid problems of damp and condensation. Cases of condensation in newly insulated lofts have been identified in previous monitoring exercises. There are several factors that can lead to condensation in lofts, such as failing to draught seal the loft hatch or the blocking of loft vents with insulation. Good practice suggests that all installations should include loft boarding in order to provide safe access to the cold water tank. In addition insulation on associated pipe work should also be included to the relevant British Standard BS5422: 2001
Energy savings for loft insulation actions have been calculated on a property type basis using The Building Research Establishment Domestic Energy Model (BREDEM).
The energy savings attributable to cavity wall insulation are included in the EEC Scheme Spreadsheet. The energy savings assume the average installation of insulation improves the u-value of the wall to0.48 W/m2K and 0.42 W/mk2 for pre 1976 and post 1976 properties respectively. Suitable cavity wall insulation products include mineral wool insulation, polystyrene beads or urea-rormaldehyde (uf) foam.
The lifetime of cavity wall insulation is estimated to be 40 years.
Insulation materials used must be certified by the British Board of Agreement (BBA) and must conform to the following British Standards.
For mineral wool insulation the relevant British Standard is BS EN 13162:2001.
For UF foam insulation, the relevant British Standard is BS 5617:1985
A 25 year guarantee must be provided to the customer when the insulation work has been completed.
