Carrying out air conditioning inspections at one of the UK’s biggest and busiest airports is no easy task – but we did it! Find out how.
A site spanning over 200,000m2, Stansted Airport comprises of multiple buildings using a mix of Air Conditioning (AC) units with an installed cooling duty of over 15.6GW. The majority of buildings comfortably exceed 12kW combined cooling capacity and require regular AC Inspections under the Energy Performance of Buildings Regulations. The Airport has invested heavily in its approach to energy management and know the importance of efficient AC. Based on our experience with similar complex systems used by the Airport, Utilitywise were selected to undertake the initial AC Inspections in 2011 and the subsequent renewals in 2016.
About Stansted Airport
After an initial meeting to discuss security and the airport’s objectives, we examined the site documentation and inspected the AC and AHUs in seven core and peripheral buildings. We also interrogated the central BMS controls. We used the information gathered to produce seven dedicated reports within the 30-day contract period.
Following the success of the initial AC Inspection project in 2011, with 195 recommendations provided over 8 reports, we were chosen to complete the 5 yearly AC Inspection renewals at the Airport and in 2016 completed the 18 required inspections.
The priority for the Airport was security and a workable timeframe. In order to ensure these needs were met, an initial project review
meeting was held and a feasible timetable established with the airport facilities and escort teams for the inspections. We adopted a
flexible approach in order to accommodate the sensitive security measures required for site visits. Regular meetings ensured full project transparency throughout.
In addition to the building specific AC Inspection Reports, we also provided a top-level spreadsheet comprising asset lists and a summary of report recommendations across the Airport. There were 308 in total, broken down by priority and type to support the Airport with analysis and further action. Driven to enhance efficiency further, Stansted Airport are also looking to explore additional opportunities with Utilitywise, such as our innovative ‘Internet of Things (IoT)’ Building Automation solutions.
