The requirement for an Energy Performance Certificate has been set by a European Directive which all member states have to implement. The EU found that a significant proportion of energy was being used by commercial and residential properties.
Small increases to the energy efficiency in the millions of properties across Europe will result in a significant overall reduction in energy usage.
When at the property the Energy assessor will collect key information that affects the energy efficiency of a property. For example, the depth of insulation in the roof will be measured as will the efficiency of the boiler. All this data is entered into EPC software which calculates the energy efficiency and produces a result on an easy to read A-G scale.
The energy report includes energy saving recommendations that can reduce household bills. These recommendations are easy to understand and set are out showing an estimated saving through the year.
The overall efficiency is shown on a colour bar chart similar to that used on white goods (shown below) along with the potential rating if the recommended measures are implemented.
The Certificate also tells you, on a scale of A-G, about the impact the home has on the environment. Better-rated homes should have less impact through carbon dioxide (CO2) emissions.
From 1st October 2008 marks the final roll-out of Energy Performance Certificates (EPCs) to all building sectors with the introduction of EPCs to rented homes and the extension and Landlords will have to provide Energy Performance Certificates for every property that they let.
The Energy Performance of Buildings Directive has introduced new certification requirements for all commercial buildings across Europe. An Energy Performance Certificate (EPC) is intended to inform potential buyers or tenants about the energy performance of a building, so they can consider energy efficiency as part of their investment or business decision to buy or occupy that building.
Non-dwellings are responsible for almost 20 per cent of the UK's energy consumption and carbon emissions. This guide provides an introduction to the Regulations for Energy Performance Certificates for non-dwellings on construction, sale or let in England and Wales. Energy Performance Certificates (EPCs) promote the improvement of the energy performance of buildings and form part of the final implementation in England and Wales of the European Directive 2002/91/EC on the Energy Performance of Buildings.
Property owners and landlords will not be able to complete any property transactions without having an EPC. Implementation dates and the level of certificate needed are being phased in based on building size and complexity
From 6th April 2008 all Commercial buildings greater than 10,000m sq
From 1st July 2008 all Commercial buildings greater than 2,500m sq
From 1st October all Commercial buildings greater than 50m sq
All buildings - 4th January 2009
An EPC is valid for ten years, or until a newer EPC is prepared
Operational Ratings Assessor (Production of Display Energy Certificates)
By 1st October 2008, all public buildings will require a display energy certificate (DEC) which shows its operation rating (OR) and an associated Advisory Report (AR).
DECs are valid for one year and the advisory report is valid for up to 7 years. DECs may only be produced by an accredited Operational Ratings Assessor (ORA). In order to become accredited, assessors must meet the relevant national occupational standard (NOS) in full, which includes full knowledge of operational rating methodology and the ability to use the approved Operational Rating.
Public authorities, and institutions providing public services to a large number of persons, who occupy space in a building with a total useful floor area greater than 1000m2, must display a valid display energy certificate ("DEC") at all times and have a valid advisory report in their possession.
