55.4 Reducing demandIn recent years there havebeen significant developments inthe efficiency of energy consumingequipment available on the market,from computers, monitors and lightfittings, to heating and cooling plant.Conversely, the greater reliance on electronicmedia and controls in our working environmentcontributes to increased consumption.Managing energy demand and controlling consumptionis central to our energy strategy and understanding thefactors that drive demand is critical to increasing our energyefficiency. Key factors at Stansted include:• Our existing infrastructure and the requirements for heatand power• The fabric and design of our buildings: older buildings tendto be less efficient, whereas newer designs tend to be betterinsulated and make more use of natural cooling and lighting• The effectiveness of our controls e.g. time schedules,movement sensors etc• Occupancy and the intensity of use of areas and equipmente.g. some equipment is required 24 hours a day, whereasoffice equipment may only be required during office hours• Behaviour and energy awareness of users e.g. whetherequipment is switched off when not required• The weather and seasonal variations in energy demand.Very cold or very hot weather can lead to an increase inheating and cooling demand respectively.Stansted has control over around 55% of the airport’s energyconsumption with the other 45% being consumed bycompanies who own or occupy premises at the airport. We willfocus our efforts on achieving greater efficiencies in Stanstedcontrolled areas, whilst encouraging efficiencies from otherairport companies through raising awareness and leadingby example.We have already achieved significant energy savings in 2009and 2010 through staff engagement, investment in renewableheating supply (our Biomass Boiler), selecting energy efficientplant when we need to replace assets and improving ourcontrol systems.In order to meet our 2020 emission reduction target we needto accelerate our efforts on energy savings and take an evenmore proactive approach to managing energy demand aspassenger numbers increase. This will require a combinationof investment in new equipment, continuing to improve ourcontrol systems and encouraging energy efficient behaviourson the part of staff and other airport workers.Energy Working Group: In 2009, we convened ourinternal Energy Working Group comprising representativesfrom our environment, engineering, finance and operationsteams. This group is tasked with coordinating our approachto technical and behavioural improvements and trackingour performance against our consumption, emissions andfinancial objectives. The group agrees an annual energymanagement plan designed to drive progress towards thelonger term energy targets and implementation of this strategy.Energy efficient behaviours: The way people use energyconsuming assets such as IT, lighting and other equipment mayhave a small impact on energy consumption individually, butthe cumulative impact across the airport is significant.As part of our on-going energy efficiency awareness campaignwe engage staff and encourage more energy efficientbehaviours such as:• Switching off equipment such as computers, monitors andlights when not required and where local control is available• Encouraging colleagues and third parties to be moreenergy efficient• Reporting faults with equipment promptly• Identifying and reporting wasteful areas• Supporting improvement programmes.18
