Energy Saving Audit

Benefits achieved

In total, the 8 costed opportunities identified had an estimated capital cost of £188,890, a simple payback of 1.3 years and a reduction in carbon emissions of 170.5 tonnes of carbon dioxide equivalent per year. The potential savings identified in these 8 opportunities was 919,000kWh.  The report enabled the school to gain a better understanding of their challenges with the building’s mechanical, electrical and plumbing aspects and to prioritise the necessary repairs/replacement works.

Further potential savings could be made through the 30 uncosted opportunities identified as part of JRP’s audit. 

Summary

Ark Academy offers learning from nursery through to further education. The school consists of A Block (Nursery & Primary), B & C Blocks (Secondary), D Block (Sports Facilities) and the 6th Form block. The buildings were constructed between 2008 and 2017. In total there are some 1,700 students and 250 staff. The school also has several outside, flood lit sports pitches.
JRP was appointed by Ark (a multi-academy trust) to audit Ark Academy's site at Wembley. The objective was to identify opportunities to reduce energy consumption, save utility costs and reduce carbon emissions.

Results

Following JRP’s thorough analysis of energy cost/usage and energy/carbon balance.
The school had some very good equipment installed to help manage and optimise energy consumption. Unfortunately, much of this equipment was either malfunctioning, not being correctly used or required further investment in time, money and training to realise the full benefits, which would include cost, kWh and carbon savings.

Recommendations for significant potential savings were identified in 8 areas:
•    Energy management and awareness training
•    Fix heating and air conditioning controls, recommission the BMS and conduct training
•    Upgrade outside sports pitch flood lighting to LED
•    Automated energy monitoring and targeting
•    Upgrade pumps to IE3 efficiency
•    Repair or replace the ground source heat pump (GSHP) 
•    Turn off borehole pump whilst GSHP not working
•    Install further solar PV arrays

A further 30 uncosted savings opportunities were identified, including recommendations for changes to out of hours use of buildings, timers on laptops, updates to light sensors, changes to cooker hobs, specific staff training.
