Energy Efficient Whitehall

The Energy Efficient Whitehall programme saw the Technology Strategy Board and DECC jointly invest £2 million in the nine pilot projects, which range from phase- change ceiling tiles to address local overheating in meeting rooms, to a natural cooling system that will be demonstrated over a couple of floors. Other solutions harness user engagement and behaviour changes, and another tackles reducing desktop power consumption.

Four major government departments are to install innovative energy efficient technology and user behaviour approaches in a series of pilot projects that will demonstrate how both government and private offices can dramatically improve their energy performance, cut energy bills and reduce carbon emissions.

The Department of Energy and Climate Change (DECC), the Department for Business, Innovation and Skills (BIS), the Department of Communities and Local Government (CLG) and the Foreign and Commonwealth Office (FCO) will install nine technologies between them.

The funded projects are as follows:

Project Title: People Power: Energy saving through engagement and behaviour change
Department: Communities and Local Government
Company: AMA - Alexi Marmot Associates Limited
Project description: Changing user behaviour is a vital, though sometimes unacknowledged, part of achieving energy efficiency. AMA have developed an innovative toolkit - WorkWareSUSTAIN - designed to reduce work related energy and carbon emissions by gathering data and delivering tailored behavioural change programmes. We will implement a low-cost, non-disruptive, pilot study that will yield estimated energy savings of around 15% from already existing office equipment.
Project Title: Energy and Carbon Reduction through Tri-Generation
Department: Foreign and Commonwealth Office
Company: British Gas Business
Project Description: The installation of a tri-generation solution, which combines CHP and absorption cooling technology, to reduce energy and carbon use at the Foreign and Commonwealth Office King Charles Street building. The initial solution is expected to deliver a 3.5% annual saving in primary carbon emissions, with the potential for further carbon and energy savings if the tri-generation was linked to the buildings hot water or heating in the future.
Project Title: Desktop Power Control Integrated to Energy Monitoring and Display
Department: Department of Energy and Climate Change
Company: Building Sustainability Ltd
Project Description: We have developed an innovative solution to accurately measure the energy use from desktop equipment and other office equipment in real time 24/7. This will show the extent to which energy is being wasted through office equipment being left on when not in use. By configuring power strips supplied by CMD to schedule power supply to the equipment and set power thresholds to ensure that energy use is linked to demand, at least 10% reductions in carbon emissions can be achieved.
Project Title: Energy Efficiency Benefits of Spectrally Rich Lighting
Department: Department for Business, Innovation and Skills
Company: Envido Ltd
Project Description: We will address poor lighting management within the BIS building, restoring the visual performance of the occupants to what would be expected of a normal level of office illumination with no additional energy consumption. This project is based on lamp replacement and control system optimisation. The lamp colour has been specifically chosen for its high colour temperature in order that the benefits of enhanced Mesopic vision can be exploited.
Project Title: SHAPER – Sustainable Habits and Actions with Personalised Experience and Reward
Department: Department for Business, Innovation and Skills
Company: GloboSense Ltd
Project Description: While staff in offices are usually keen to reduce energy consumption, one main obstacle is their perceived inability to measure and control their energy usage. Through the use of personal feedback and control technology, SHAPER is a novel concept of bringing awareness, giving ownership of the energy challenge to the building users and rewarding them for sustainable behaviour change to achieve energy savings. The estimated carbon savings in BIS are 12.1 tonnes (demonstration area) and 404 tonnes (whole building), accounting for a 12% carbon reduction.
Project Title: Visible Energy Reduction Trials
Department: Foreign and Commonwealth Office
Company: Real-Status Limited (formerly Intergence Optimisation Limited) and Green Energy Options Limited (Partner)
Project Description: The project will focus on materially reducing power consumption within the FCO's King Charles Street building. The project will present a monitoring framework that will measure and display power consumption in a way that will encourage staff to be energy-wise. The visual displays will help FCO staff target energy wastage and gain rewards where they meet or improve upon the energy budgets they have been given. The project will support the FCO with their existing sustainability programme by establishing and monitoring a behavioural change campaign that will utilise this visual approach to understanding where energy is being wasted.
Project Title: Design and Installation of new innovative LED lighting in the DECC Building
Department: Department of Energy and Climate Change
Company: Novah Limited
Project Description: We propose to convert traditional lighting fixtures to LED luminaires. We will upgrade the current light fittings with replacement LED lamps to improve the existing mix of low output, high power lamps. The test area will focus on 750 LED lamps within the building, to provide a large enough area for statistical sampling. By changing from existing fluorescent lamps to LED, the light level can be improved in terms of quality, by introducing daylight light quality, and the power and carbon consumption can be reduced by 60 to 70%.
Project Title: Naturally Cooled and Daylit Whitehall
Department: Communities and Local Government
Company: SolaVeil Limited
Project Description: Our vision is to drastically reduce building energy needs and a building's carbon emissions by using two complementary energy efficiency approaches. SolaVeil Light redirection and natural daylight enhancement technology will reduce solar heat gain whilst projecting cool, glare free, natural daylight into the building's interior without sacrificing privacy or visual security and create a more comfortable and healthier working environment. A Thermal Energy Store will enhance the cooling process, dramatically reducing energy required to operate air conditioning within the building.
Project Title: Utilising a Passive Ceiling System to reduce Energy and Carbon Emissions
Department: Department of Energy and Climate Change
Company: Willmott Dixon
Project Description: Our project is based around Phase Change Material that absorbs and stores latent heat, releasing it when the temperature of the space drops. By reducing the need for mechanical cooling, energy and carbon emission savings are estimated to be in the order of 55% (a carbon saving of 466kg of CO2 each year and an energy saving of 868kWh each year for the rooms modelled) and are based on predicted room cooling demands.
