Energy Efficiency Reports


 
Energy Efficiency Reports

Since 1st October 2008 any building built, sold or rented has required an Energy Performance Certificate by Law.

The need for Energy Performance Certificates has been brought about by Legislation introduced by the Government in an attempt to slow down Global Warming.  Global Warming has accelerated at a speed which has alarmed Scientists and Governments alike.  The biggest contributor to this climate change is CO2 gas emissions.

As stewards of our planet, it is our duty to act now and make the changes necessary to reduce these emissions and make our world a safer place for the generations to come.  Housing equates to 29% of energy use in the UK, which is more than the combined total of transport including cars, trains and planes.

The Purpose

Energy Performance Certificates (EPC) are being introduced to help improve the energy efficiency of buildings.  The certificate provides ‘A’ to ‘G’ ratings for the building, ‘A’ being the most efficient and ‘G’ being the least, with the average, being ‘D’.

Energy Performance Rating

The Energy Performance Rating is based on a visual inspection only.  It will not be necessary to clear cupboards, remove furniture or roll back carpets but it will be necessary to view meters and enter any loft space. The report will reflect the visible condition of the property on the day it is inspected. Photography will form a part of the inspection process.

When looking at the ratings; the higher the number: the better the performance, which should mean lower fuel bills. The ratings and improvements suggested in energy advice reports will help to prioritise the different ways of saving energy.

Some improvements make obvious economic sense, and others are really only realistic considerations when a particular item requires replacing.

Houses and flats can vary widely in size, therefore an allowance is made for the size of the property. So the basis of the energy rating is to try and predict the fuel cost of the property, divide this cost by the floor area, and fit the results onto a simple scale – as noted on the scale (fig 1) the higher the number, the better.

Ratings are calculated on the basis of ‘standard occupancy’. This is essential because the way that occupants use a property can increase or decrease energy use by very large factors. The use of standard occupancy allows a level playing field for comparison between dwellings, regardless of how the current occupants use it. 

Standard Assessment Procedure (SAP)

The SAP has been adopted by the Government as the UK methodology for calculating the energy performance of a dwelling. 

The calculation is based on a range of factors which contribute to energy efficiency:

1.   Materials used for the construction of the dwelling

2.   Thermal insulation of the building fabric

3.   Ventilation equipment and its characteristics

4.   Solar

5.   The fuel used to provide space and water heating

6.   Renewable energy technologies
