Milton Keynes Parks Trust - energy efficiency audits

Milton Keynes Parks Trust required energy efficiency audits, an onsite renewable energy feasibility study and a lifecycle cost analysis for three commercial properties in Milton Keynes.

Our energy efficiency audits covered three buildings:

  • Campbell Park Pavilion.
  • Shenley Pavilions.
  • ​Linford Forum.

We conducted an energy audit covering existing building services and fabric and building use and management to identify energy efficiency and carbon emission savings. The work also included a detailed Lifecycle Cost Analysis (LCA) for those energy technologies that were deemed appropriate and suitable.  Where the LCA was calculated, this information was presented as a financial ‘Net Present Value’ (NPV). The LCA followed the methodology as defined in part five of the ISO BS 15686:2008 standard on life cycle costing.

The scope of our energy efficiency audit work included:

  • Onsite energy efficiency and renewable survey.
  • Benchmark and energy data analysis.
  • Renewable technology feasibility study.
  • ​Detailed lifecycle cost analysis.

Improvement opportunities

The surveys identified a range of quantified energy efficiency improvement opportunities to reduce energy costs and carbon emissions. These included:

  • Correction of utility metering errors (half hour metering).
  • Operational changes to the building management system.
  • Gas boiler control and settings.
  • ​Key staff engagement and training.

Identifying the best investment opportunities

The result of the lifecycle cost analysis helped the organisation identify the best investment options including:

  • A potential photovoltaic array development providing an NPV of £110,000 over the next 25years.
  • ​A potential large, onsite wind turbine with a projected NPV of £370,000 over 25 years.

Our work also identified a number of technologies that were not financially viable (ie those with limited funding opportunities including solar thermal hot water, biomass heating and heat pump heating and cooling).

The risk assessment associated with our analysis ensured that the client had a full view of the technical considerations, potential policy change impacts, future funding opportunities and any impact of fuel price variations.

Energy Surveys & Audits

Our comprehensive energy surveys and audits provide advice on where the main energy management opportunities lie, and identify the need for more detailed investigations, if required. We also assess the feasibility of energy efficiency measures and renewable energy technologies, in order to reduce a building's energy consumption and carbon footprint.

Renewable Energy Feasibility Studies

We have wide-ranging experience of feasibility studies for both domestic and non-domestic clients. As an independent, not-for-profit organisation with over 25 years' experience in the sector, we're ideally placed to give you unbiased advice about renewable energy.


Many ‘low-energy buildings’ are found to use more energy than the designers thought they would. Benchmarking is key to evaluating a building's likely energy costs, and we can provide a service that does this for you.
