Services - Renewable Energy Systems Feasibility

Renewable energy systems are becoming an increasingly attractive option in the light of rising fossil fuel costs and European commitments to reducing environmental pollution. A combination of best practice building thermal design, renewable energy systems and good control can lower fuel costs, reduce environmental pollution, create local employment, increase security of supply and provide a more sustainable energy future.

Carbon Twelve can offer bespoke independent feasibility assessment packages for the the commercial, industrial, public and domestic sectors where renewable solutions are being considered. Independent renewable feasibility assessment packages can include:

  • Heat load calculations for the purposes of sizing renewable systems.
  • Estimation of annual heat consumption and costs.
  • Consideration of improved thermal design for reduced annual heat requirements / installed renewable system capacity.
  • Assessment and recommendations regarding the practical design of renewable systems.
  • Technical possibilities, practical considerations, capital cost implications.
  • Running cost implications and comparison to conventional fossil fuelapproaches.
  • Consideration of integrated solutions using combinations of renewable technology.
  • Assessment and guidance on appropriate typesof heat distribution system and controls.
  • Summary of advantages and disadvantages for the systems under consideration.
  • Options currently available for obtaining grants for the installation of renewable systems.
  • Assistance with identifying suitable equipment suppliers and obtaining quotes.
  • Simple payback analysis.
  • Life cycle costing analysis.


Renewable systems considered include:

  • Solar Thermal
  • Heat Pumps
  • Wood Chip / Wood Pellet Boilers & Stoves
  • Photo Voltaic (PV)
  • Small Scale Wind



  • Domestic Houses
  • Hotels
  • Hospitals
  • Offices
  • Factories
  • Industrial facilities
