Building in Energy Efficiency
To create sustainable buildings in both residential and commercial construction, it is important to consider how the structure is built and with what materials. We must begin to realise the impact our homes are having on the environment through energy wastage, and build energy efficient measures into our homes and offices.
For detailed information on energy efficiency and on energy grants in your area, contact the Energy Saving Trust or your local Energy Efficiency Advice Centre.
Here are a few energy saving tips which you can implement in your own home, or hire a contractor to do it for you:
Draught Proofing will prevent wasted heat and can save you £10 - £15 a year. Seal in the warm air and keep out the cold, and stop excessive use of your heating by installing draught proofing on windows and doors.
Your home can lose 20% of its heat through badly insulated frames and singe glazing. Create an insulating barrier by having double glazing installed.
Loft Insulation can protect against the loss of around 25% of your homes heat that occurs through heat rising. Installing 200mm of loft insulation can reduce this by 10%.
Cavity Wall Insulation can be fitted to reduce the loss of 35% heat. With the installation of cavity wall insulation, this is diminished to about 15%. Most homes built since the 1930s have a cavity between the inner and outer wall of the house which can be insulated.
New Technology:
Solar PV (photovoltaic) uses solar electric technology, as opposed to solar thermal technology. It generates electricity from daylight via advanced semi-conductor technology. It is now possible to have installed solar PV roofing, and with some areas there are grants available for energy efficient home renovations like this.
As having a solar roof means having your own power source, it is also a strong selling point and is low maintenance, functioning fully for 30 years plus. It is therefore a financially rewarding building renovation.
Solar PV roofing is available as bolt on or integrated:
- Bolt onThese bolt on to the current roof tiles
- Integrated – Replacing roofing material with PV tiles or Cladding
Planning Permission
Usually, solar panels are granted under ‘permitted development rights’. This means that if the solar roofing installation is virtually flush with the existing roof, you will not require a planning application. It should also be acceptable if your solar panelling will be facing away from roads and footpaths. You may need an application if it is:
- Larger than the current roof
- A flat/house divided into flats
- In a conservation area
- In a National Park
- A listed building
- In an Area of Outstanding Natural Beauty
- Covered by Article 4 by the local authority
It is advisable to always check with the local authorities before undertaking any major works on your home. Building Control will also need to be informed, and any visit they choose to make may incur a charge.
