New Technology

This page is intended to give a brief overview of low carbon and renewable energy technology. This is a rapidly changing field with greater efficiencies and improvements being achieved with every year that passes.

The attractiveness of renewables as an energy source in domestic buildings has been significantly enhanced by the introduction of substantial incentives in the form of Feedin Tariffs (FITS) and Renewable Heat Incentives (RHIs). These have reduced the payback period and can provide a healthy return on the money ‘invested’ in new technology.
Before investing in a new heating system or ‘green’ technology to generate electricity it is important to understand first how your building uses energy now and how energy consumption can be reduced. The first stage is to have a look at the energy performance certificate on the property. You will have seen the headline figures on the graph on the agent’s sales particulars but detailed information is provided in the full certificate that runs to five or six pages. The crucial information is the potential ratings. This is the performance that can be expected by adopting relatively low cost and cost-effective measures. The certificate will detail the savings that can be made from adopting the individual measures recommended.

In some houses, including Listed Buildings, improvements such as installing shutters or draught-proofing can make significant improvements. Reducing energy consumption by taking the simple steps is the most effective way of reducing your bills. The less energy that is needed means that a smaller, cheaper renewable energy source or low carbon heating system can be installed.
There are two basic types of technology. The first type is used to provide heating and/or hot water and the second is used to generate electricity. As new build housing becomes zero carbon and fuel costs rise an understanding of the available options has become more important.
