How we can help with Display Energy Certificates, Energy Performance Certificates and energy audits
As part of our commitment to energy efficiency we can provide you with a range of services or certificates.
A DEC shows the energy performance of a building based on its actual annual energy consumption and the carbon dioxide emissions that result from that energy use. This is shown as a rating from A to G, where A has the lowest carbon dioxide emissions (best) and G the highest carbon dioxide emissions (worst).
The rating is also shown as a number. A typical building of its type would have a rating of 100. A building with twice the typical carbon dioxide emissions would have a rating of 200 (or G).
A DEC must be accompanied by an advisory report containing recommendations for improvement of the energy performance of the building. The DEC must be renewed every year. The advisory report is valid for seven years.
Much like the multi-coloured sticker on new appliances, EPCs tell you how energy efficient a building is and give it a rating from A (very efficient) to G (inefficient). They let the person who will use the building know how costly it will be to heat and light, and what its carbon dioxide emissions are likely to be.
The EPC will also state what the energy efficiency rating could be if improvements are made, and highlights cost-effective ways to achieve a better rating. Even if you rent your home, some improvements noted on the EPC might be worth your while – such as switching to more energy-efficient light bulbs.
Once produced, EPCs are valid for ten years.
Your energy audit will show you which improvements can be made to save energy and water consumption, reduce greenhouse gas emissions, and save money on utility bills.
You will be provided with an Audit Report, which will cover areas from the audit for example – lighting, heating, insulation, energy and water saving advice, improvements to the fabric of the building to reduce energy costs.
