Suffolk County Council Biomass Wizard, Feasibility Wizard and Payback Wizard

These tools have been developed by Gary Battell of Suffolk County Council. Many of the spreadsheets have been designed to address specific problems encountered while specifying and designing woodfired heating installations in Suffolk County council owned buildings. Some of these spreadsheets have been reviewed by commercial boiler installers and heating engineers and all represent many years of practical experience of designing, procuring and using woodfuel boilers and woodfuel supply chains.

Subject areas covered include:

  • Data conversion tables
  • Calorific values or different fuel types
  • Summaries of pollution control regimes and legislation
  • District heating
  • Boiler sizing
  • Fuel storage costs
  • Project management and responsibilities
  • Fuels costs
  • Heat sale tariffs
  • Wood densities
  • Wood chip production costs
  • Regional and county forestry statistics

Suffolk County Council have generously made these tools publicly available and free of charge but encourage users to make a donation to the Ashden Awards.

Please note that these tools have been designed to run on Excel 2007 (or newer) and are not compatible with earlier versions.
