Predicted Energy Assessment of 16

Bungalow, Undercliff,Cleadon,SR6 7UX

Dwelling type: Bungalow, DetachedDate of assessment: 08.Dec.2015Produced by: Frank Dixon AssociatesTotal floor area: 530.66 m2

This document is a Predicted Energy Assessment for properties marketed when they are incomplete. It includes a predicted energy rating which might not represent the final energy rating of the property on completion. Once the property is completed, this rating will be updated and an official Energy Performance Certificate will be created for the property. This will include more detailed information about the energy performance of the completed property.

The energy performance has been assessed using the Government approved SAP2012 methodology and is rated in terms of the energy use per square meter of floor area; the energy efficiency is based on fuel costs and the environmental impact is based on carbon dioxide (CO2) emissions.

Energy Efficiency Rating

Very energy efficient - lower running costs

A(92 plus)

B(81-91)

C(69-80)

D(55-68)

E(39-54)

F(21-38)

G(1-20)

Not energy efficient - higher running costs

England EU Directive2002/91/EC

94

Environmental Impact (CO2) Rating

Very environmentally friendly - lower CO2 emissions

A(92 plus)

B(81-91)

C(69-80)

D(55-68)

E(39-54)

F(21-38)

G(1-20)

Not environmentally friendly - higher CO2 emissions

England EU Directive2002/91/EC

95

The energy efficiency rating is a measure of theoverall efficiency of a home. The higher the ratingthe more energy efficient the home is and the lowerthe fuel bills are likely to be.

The environmental impact rating is a measure of ahome's impact on the environment in terms ofcarbon dioxide (CO2) emissions. The higher therating the less impact it has on the environment.
