  4. The feasibility of biomass heating for churches in the Diocese of Canterbury Summary of Findings by Matthew Morris Kent Downs AONB Unit (ADAFOR Interreg project)

  5. ‘From Anecdote to Evidence’ (2013) • Heating in churches helps improve comfort • “…Improving buildings can have a positive effect on church growth…”

  6. Delivering heat in churches • Expensive • Poor performance • Rural locations - oil, LPG and electricity • Age, maintenance, moisture, safety…

  7. Delivering heat in churches • Impact • Low internal temperatures • Comfort levels hard to maintain • Problems with damp and condensation • Damage to building fabric, furniture, paintings… • Impact on congregation growth

  8. What do we know? • Most churches have some form of heating • But nearly all are under-heated • Some systems not used • Rural churches – most expensive fuels • Maintenance costly • Visual impact • Oil theft • Re-ordering projects present opportunities

  9. What do we know? • Uptake of renewable energy is rare • Of >500 churches in Kent…~5 with systems? • St. Stephen Lympne: GSHP • St. Mary Ashford: Geothermal heat pump • St. Anthony Alkham: Solar PV • St. Nicholas Rochester: Biomass and solar PV • RE technologies are expensive • Fundraising required • But – The RHI subsidy is a game changer

  10. DioCan + AONB – collaborative project • ‘Initial feasibility and design principles for biomass heating in churches for the Diocese of Canterbury’ • £12k project total - funded by ADAFOR Interreg (EU ERDF) • Why? • Biomass per kWh is cheaper than gas, oil, LPG and electricity • Renewable Heat Incentive (RHI) - 20 yr subsidy • Significantly improved payback • High grade heat from biomass boilers • Improved heating regimes • Excellent secondary benefits • Sustainability + reduced carbon footprint • Redundant/unsafe heating systems can be discarded

  11. Is guidance available? • Eco Congregation • Shrinking the Footprint • English Heritage • Ecclesiastical • Diocese of Oxford • Churches Conservation Trust

  12. But… • Very general • Not specific to locations • Does not help with feasibility or business case (£££)

  13. Process • Around 20 PCCs expressed an interest to DioCan • From these 12 locations were selected Borden, Boxley, Detling, Hollingbourne, Kingston, Lyminge, Molash, Ospringe, Patrixbourne, Selling, Stalisfield, Wychling

  14. Phase I: Site visits • Building survey (approaches to heating, heritage) • Meetings with PCC members • Energy data collection • Six main criteria: • Existing energy use • Re-ordering opportunities • Practical aspects of installing renewable heating • Financial & technical issues • Potential planning issues • PCC resources (and enthusiasm)

  15. Reduced initial list of 12 to 5 churches • Borden, Boxley, Detling, Selling, Lyminge • Phase II • More detailed survey (SEWF) • Involving M&E engineer (MCA) • Review by Nick Lee Evans (DAC approved architect) • Report and presentation to DAC committee • Biomass heating received tacit approval from the DAC • It is a viable option…but needs careful study

  16. Phase III • Detailed architectural advice • Molash, Borden, Selling • Led by Lee Evans Partnership • Results by early 2015
