Venue details

Name of owners: Peak District National Park Authority
Who installed green technology:
  • Main M&E contractor: MJ Robinson ltd
  • Sub- contractor biomass: Rural Energy
  • Civils contractor (for fuel store): FACE Structures Ltd
Why they did it: Prior to investing in the biomass boiler, the Authority had already improved the efficiency of the heating system by utilising more efficient controls, insulating heating pipework and insulating the building as far as possible, alongside a number of initiatives to reduce electricity use.To achieve any further significant improvements to the performance of the building, a lower carbon heating fuel was required. Biomass was the most suitable option for moving away from a reliance on fossil fuels while providing a suitable, reliable heat source for the building.
Benefits: Significant reduction in carbon emissions. The capital investment made by the Authority is repaid by the savings made on gas use and Renewable Heat Incentive tariff payments within 12 years. The use of biomass is thought to be a more reliable long term solution than gas alone.
What they did to get approval from National Park for the work: The project to install the system was two years in the planning and involved gaining approval from the National Park Planning committee for the construction of the biomass fuel store. Approval was also required from the National Park Authority’s members for the significant financial expenditure and disruption that the project entailed.
What were the biggest problems faced: A key hurdle for the project managers to overcome was the perception of biomass as an unreliable method of heating the building. Authority members were convinced that the system would be reliable in the long term and, with the backup of gas boilers, would ensure that the building is never left without heat.The project also caused significant disruption to the occupiers of the building (namely National Park Authority staff) so managing expectations and the inconvenience caused was a significant challenge over the 4 months on site to complete the installation.
What did it cost, what savings are made: The project cost a total of £327,000. The total savings, running costs and income from the RHI make the total cost benefit £17,800 per annum for the next 20 years. The payback period without taking inflation or rising gas costs into account is 12 years.
