Typical savings and payback.

The beauty of energy efficiency in buildings is that it not only reduces CO2 emissions, but also saves money by saving energy. A growing number of reports (e.g. from ECOFYS, Stern, McKinsey, CEPS and the UN’s IPCC) all point to the fact that better energy efficiency in buildings particularly by means of insulation is one of – if not the - most cost-effective measure to reduce CO2 emissions.

The IPCC says: “Energy efficiency options for new and existing buildings could considerably reduce CO2 emissions with net economic benefit.”

Societies all over the world are actually losing money by not taking initiatives to save CO2 and costly energy in their buildings.

The costs and paybacks shown in the table are approximate, are provided for illustrative purposes only and based on a gas heated semi-detached house with 3 bedrooms. Savings assume a gas price of 5.47c/kWh. Some of the savings made may be taken in increased comfort.

Installed Costs and paybacks assume that installation is undertaken by a professional installer and both loft and cavity wall insulation costs include a subsidy which can be obtained under the HES scheme.

The above table is intended as guide and is included for reference purposes only. Many other factors such as family size, energy source / provider, lifestyle, air tightness, glazing, aspect and other structural factors can affect the level of savings achieved. A detailed energy audit or BER assessment will give a more accurate analysis of the energy usage & potential savings possible in an individual dwelling.
