Summary of this home's energy performance related featuresElement Description Energy Efficiency

Walls Average thermal transmittance 0.25 W/m²K

Roof Average thermal transmittance 0.17 W/m²K

Floor Average thermal transmittance 0.12 W/m²K

Windows Fully double glazed

Main heating Boiler and radiators, oil

Main heating controls Time and temperature zone control

Secondary heating Room heaters, wood logs —

Hot water From main system, plus solar

Lighting Low energy lighting in 83% of fixed outlets

Air tightness Air permeability 8.0 m³/h.m² (as tested)

Thermal transmittance is a measure of the rate of heat loss through a building element; the lower the value the betterthe energy performance.Air permeability is a measure of the air tightness of a building; the lower the value the better the air tightness.

Current primary energy use per square metre of floor area: 67 kWh/m² per year

Low and zero carbon energy sourcesLow and zero carbon energy sources are sources of energy that release either very little or no carbon dioxideinto the atmosphere when they are used. Installing these sources may help reduce energy bills as well as cuttingcarbon. The following low or zero carbon energy sources are provided for this home:• Biofuel secondary heating• Solar water heating

RecommendationsThe measures below will improve the energy performance of your dwelling. The performance ratings afterimprovements listed below are cumulative; that is, they assume the improvements have been installed in the orderthat they appear in the table. Further information about the recommended measures and other simple actions youcould take today to save money is available at www.direct.gov.uk/savingenergy. Before installing measures,you should make sure you have secured the appropriate permissions, where necessary. Such permissions mightinclude permission from your landlord (if you are a tenant) or approval under Building Regulations for certain typesof work.
