Predicted Energy Assessment F07 Dwelling type: Top floor Maisonette 80 Woodcote Valley Road Date of assessment: 27 August 2014 Purley Produced by: Mark Heptonstall Croydon Total floor area: 73.67 m² CR8 3BE This is a Predicted Energy Assessment for a property which is not yet complete. It includes a predicted energy rating which might not represent the final energy rating of the property on completion. Once the property is completed, an Energy Performance Certificate is required providing information about the energy performance of the completed property. Energy performance has been assessed using the SAP 2009 methodology and is rated in terms of the energy use per square metre of floor area, energy efficiency based on fuel costs and environmental impact based on carbon dioxide (CO2) emissions.
Energy Efficiency Rating
The energy efficiency rating is a measure of the overall efficiency of a home. The higher the rating the more energy efficient the home is and the lower the fuel bills are likely to be.
Environmental Impact (CO2) Rating
The environmental impact rating is a measure of a home’s impact on the environment in terms of carbonn dioxide (CO2) emissions. The higher the rating the less impact it has on the environment.
