Our knowledge of this subject grows daily and we are realising that with every direction we take, there are compromises that have to be considered. Issues such as embedded carbon, fuel conversion data, availability of feedstock and the building structure, amongst many other factors, have to be considered when selecting renewable/sustainable energy solutions.

As part of our studies, we have carried out a comprehensive assessment of the merits of air-to-water heat pumps, from two of the major manufacturers. We have considered their suitability as a replacement for condensing gas fired boilers to existing properties and as an alternative to direct burn fossil fuels in new build properties. Comparisons across the full energy supply spectrum eg Natural gas, Oil LPG and electricity have been carried out to assess the realities of payback.

Another commission included an in depth report on the subject of Anaerobic Digestion, which has questioned the logic that the future for renewables is an all-electric world. Whilst there is land on which to grow crops, a gas infrastructure features in the renewable framework.

As part of our ongoing training and commitment to Renewables, our proprietor has been accepted for an MSc course in Renewable Energy and the Built Environment at the Centre for Alternative Technology. This will include modules on Wind, Biomass, Hydro Electricity (already completed), Solar Thermal, Geo Thermal, Building Properties and PV.
