Residential or Domestic Energy Performance Certficates |
Example Energy Ratings |
|
| The EPC is generally a five or six page document which contains:- •'A' to 'G' ratings for the building, with 'A' being the most energy efficient and 'G' being the least, with the average being 'D'. • A calculation of the carbon footprint of the dwelling. • A summary of the efficiency of the main parts of the property. • Specific recommendations to reduce the carbon footprint with an indication of cost savings if undertaken.

So what does the Energy Assessor do at the property? |
||
| The energy assessor will survey the following aspects of the property: The original build date and presence of any extensions The floor area of property The construction of the walls, floors and roofs The glazing The type of heating and hot water system The presence of loft or wall insulation The presence of any solar panels or wind turbines. Utilising all the information collected, the data will be input into the approved software which will then generate the certificate. |

| The certificate that is produced will make some recommendations to improve the energy efficiency of the property. These are dependant on the type of property that has been assessed and may include: Loft insulation Loft insulation laid in the loft space or between roof rafters to a depth of at least 270 mm will significantly reduce heat loss through the roof; this will improve levels of comfort, reduce energy use and lower fuel bills. Insulation should not be placed below any cold water storage tank, any such tank should also be insulated on its sides and top, and there should be boarding on battens over the insulation to provide safe access between the loft hatch and the cold water tank. The insulation can be installed by professional contractors but also by a capable DIY enthusiast. Loose granules may be used instead of insulation quilt; this form of loft insulation can be blown into place and can be useful where access is difficult. The loft space must have adequate ventilation to prevent dampness; seek advice about this if unsure. Further information about loft insulation and details of local contractors can be obtained from the National Insulation Association. Cavity wall insulation Cavity wall insulation, to fill the gap between the inner and outer layers of external walls with an insulating material, reduces heat loss; this will improve levels of comfort, reduce energy use and lower fuel bills. The insulation material is pumped into the gap through small holes that are drilled into the outer walls, and the holes are made good afterwards. As specialist machinery is used to fill the cavity, a professional installation company should carry out this work, and they should carry out a thorough survey before commencing work to ensure that this type of insulation is suitable for this home. They should also provide a guarantee for the work and handle any building control issues. Further information about cavity wall insulation and details of local installers can be obtained from the National Insulation Association. (link above). New condensing boiler A condensing boiler is capable of much higher efficiencies than other types of boiler, meaning it will burn less fuel to heat this property. This improvement is most appropriate when the existing central heating boiler needs repair or replacement, but there may be exceptional circumstances making this impractical. Condensing boilers need a drain for the condensate which limits their location; remember this when considering remodelling the room containing the existing boiler even if the latter is to be retained for the time being (for example a kitchen makeover). Building Regulations apply to this work, so your local authority building control department should be informed, unless the installer is registered with a competent persons scheme¹, and can therefore selfcertify the work for Building Regulation compliance. Ask a qualified heating engineer to explain the options. ecoEPCs Home Page Internal or external wall insulation Solid wall insulation involves adding a layer of insulation to either the inside or the outside surface of the external walls, which reduces heat loss and lowers fuel bills. As it is more expensive than cavity wall insulation it is only recommended for walls without a cavity, or where for technical reasons a cavity cannot be filled. Internal insulation, known as drylining, is where a layer of insulation is fixed to the inside surface of external walls; this type of insulation is best applied when rooms require redecorating and can be installed by a competent DIY enthusiast. External solid wall insulation is the application of an insulant and a weatherprotective finish to the outside of the wall. This may improve the look of the home, particularly where existing brickwork or rendering is poor, and will provide longlasting weather protection. Further information can be obtained from the National Insulation Association. It should be noted that planning permission might be required. Solar photovoltaic (PV) panels A solar PV system is one which converts light directly into electricity via panels placed on the roof with no waste and no emissions. This electricity is used throughout the home in the same way as the electricity purchased from an energy supplier. The British Photovoltaic Association has up-to-date information on local installers who are qualified electricians and on any grant that may be available. Planning restrictions may apply in certain neighbourhoods and you should check this with the local authority. Building Regulations apply to this work, so your local authority building control department should be informed, unless the installer is appropriately qualified and registered as such with a competent persons scheme¹, and can therefore self-certify the work for Building Regulation compliance. The assessment does not include the effect of any feed-in tariff, which could appreciably increase the savings that are shown on this EPC for solar photovoltaic panels. |
