London Stansted Airport benefits from Asset Optimisation Service Contract with Honeywell. 

Reduced energy consumption and Honeywell management of multi- disciplinary services aid airport cost-efficiency.

BRACKNELL, UK, 7 MAY 2001 – London Stansted Airport is reducing its energy consumption, whilst ensuring passengers' and airport workers' comfort, through an asset optimisation service contract with Honeywell's Enterprise Service Solutions (ESS) business.

London Stansted is Britain's third largest Airport, handling over 10.5 million passengers a year. With a year on year growth of 30 per cent, it is one of Europe's fastest growing airports. A £200 million project to develop Stansted to a capacity of 15 million/year began this year.

Honeywell's resident site team maintains Stansted's heating, chilling, air handling and ventilation plant, lighting systems, hot and cold water services, drainage and sewage systems, UPS (uninterruptible power supplies) and building management systems throughout the airport complex.

Honeywell was awarded the five-year contract in August 1998 after Stansted Airport had been attracted by Honeywell's innovative Optimum Maintenance Strategy (OMS™). "The Honeywell strategy provided a solution to our search for a better way of managing our planned maintenance – one that is designed to reduced our overall costs," explained Alvar Digby, BAA Engineering Contract Manager at Stansted. The strategy is intended to provide a tailor-made service programme that will have a positive impact on an organisation. OMS objectives are to support an organisation's business objectives and processes, to achieve best practice in the management, implementation and performance of its resources, and to provide measurable results.

A positive indicator of the success of the partnership between BAA and Honeywell ESS is that the contract value has increased by 45% since it started.

Plant Rooms
The airport terminal has two huge plant rooms, located under the concourse area and running the full length of the building. All the terminal's heating and ventilating services are delivered through ducts emerging at the 24 "trees" that support the concourse's award winning roof design. There are 24 air handling units – one per "tree".

The trees are the conduits for most of the central services within the terminal, in addition to the air conditioning systems: lighting, fire hoses, telephones and information displays. Supply air is delivered via diffusers at low level while air is extracted through the core of each tree. To reduce energy consumption this air passes around the high power up-lighters, taking this heat energy back to the air handling units.

Cost efficiency
"Everything we do for Stansted Airport has its root in cost-efficiency, whilst ensuring passengers' comfort," explained Matthew Eastwood, Honeywell Service Manager at Stansted. "The services are based on the OMS programme, which is a unique mix of knowledge, process and technology which maximises asset performance through efficient use of resources and provides the management process to measure results. Our commitment to deliver and continually improve against agreed criteria is borne out by the long-term relationships we have built with Stansted Airport and many others in our customer base.

"Honeywell's management approach towards providing best value to the airport is to train and develop its engineering team to be able to service and repair the majority of assets. This includes gas boilers and refrigeration plant. The maintenance of certain plant items is subcontracted to specialists, where it is not viable to provide training."

After Honeywell took over from five previous contractors, Stansted management decided to implement its own optimisation program called AMA (Acquire and Maintain Assets). "AMA follows the thinking of Honeywell's OMS," observed Alvar Digby. "Under AMA, we will look at every asset together with the maintenance requirements to determine criticality. We will then set the service levels accordingly; this will reduce overall running costs. We may find that it is more cost- effective not to maintain certain non-critical plant items, because it would be cheaper to let them run to fail, and then replace with new."

Stansted Airport concedes that, although Honeywell was asked at the outset to be proactive in seeking more cost-effective plant and maintenance solutions, these initiatives were put on hold pending the airport's adoption of AMA. "We are yet to see the full benefits of what the Honeywell strategy can achieve," said Alvar Digby. "We continue to see our relationship with Honeywell as a long-term partnership working to reduce operating costs."

"In a recent partnership project, we modified the passenger terminal's lighting controls. We estimate this will reduce annual energy costs by £14,000. The partnership has now been asked to look at the heating and ventilating services at Enterprise House, where we believe we can provide additional energy savings. This can be achieved by increasing the airport's utilisation of 'free cooling', that is, selectively recirculating air or taking air in from outside, whichever is the more energy-efficient at that time."

Central responsibility
The maintenance work now carried out by Honeywell combines five contacts previously managed by Stansted, so there have been cost benefits through the greater efficiency of dealing with one contractor. "Although we have always employed our own maintenance personnel to carry out first-line response duties and specialist tasks, we employ contractors to carry out a large proportion of our work," said Alvar Digby. "Contractors have a management structure in place, they take care of Health and Safety, training and holiday coverage, whilst also making budgeting easier because we know in advance what the total cost will be."

Project work at Stansted above a certain cost level is put out for competitive tender. This process is managed by the airport's project group, which is separate from the engineering and maintenance department. While Honeywell's contracted responsibility is to maintain existing equipment, it can tender for project work, if it desires. Honeywell's largest recent additional engineering project was the removal and replacement of large calorifiers.
