Measuring energy efficiency to ensure robust energy investment decisions

One of the commonly cited barriers to the uptake of energy reduction projects is the lack of trust in the level of savings being claimed.

In order to gain stakeholder confidence and buy-in it is important to prove the success of any energy reduction project or energy performance contract. This requires that savings are made clearly visible and that the methods used to assess them are robust and transparent whilst maintaining a pragmatic balance between M&V cost and the need for certainty.

Before committing to a major investment programme across a large number of sites, Whitbread, the UK’s largest hotel, restaurant and coffee shop operator, wanted to gain an accurate understanding of the potential energy and cost saving for each technology across its estate and appointed JRP Solutions to establish the efficiency of some cellar management systems and the effectiveness of energy saving measures implemented.

JRP considered a range of technologies through pilot studies at sample sites to reduce energy in refrigeration of beer cellars which accounts for a significant proportion of electricity used in Whitbread’s restaurants. The pilot studies included potential improvements to refrigeration compressor efficiency, sophisticated building control system and measures to restrict air movement.

JRP Solutions used the International Performance Measurement & Verification Protocol (IPMVP) to determine the savings in each case, providing an independent and impartial quantified and evidenced report of energy savings achieved by improvement projects. All analysis was carried out by JRP Solutions analysts who are qualified in both IPMVP and ISO 50001 and who have many years of practical operational as well as energy expertise.

JRP Solutions report was invaluable in directing Whitbread’s energy efficiency investment programme as, in this case, the analysis found that some technologies did not offer any benefits, whilst others provided normalised savings of between 9% and 15%.
