Halcrow Group Ltd, Bristol, saved a major university £180K p.a. on energy (= 2,816 tonnes of CO2) and £100K p.a. on water through automated monitoring & targeting, low
energy lighting, control systems, water leak management etc. (2004)
Knauf Insulation, Torfaen, South Wales (Avon & Somerset EEMG member), installed Fluoresave's microprocessor-control system into their discharge lighting circuits for metal halide, sox and fluorescent lighting and achieved energy savings ranging from 22% to 41% on those circuits. (2005)
Nationwide Building Society. The installation of improved over-door air curtain controls in 50 branches has given a 30% reduction in energy consumption per unit. This is saving 62,315 kWh of electricity p.a. whilst reducing CO2 emissions by 26.8 tonnes. Enhanced controls on air-conditioning
units are also saving 15% on electricity (= 214 tonnes of CO2). (2004)
Natural Environment Research Council (NERC), HQ in Swindon, are investing a dedicated £176K budget within the group for several energy and CO2 saving projects. These include new video conferencing systems across six sites to minimise unnecessary travel and CO2 emissions, two 1.5 kW wind turbines saving 38 tonnes of CO2 p.a., an all electric car to be charged with solar panels or green
electricity, and secure on-site bicycle sheds to reduce commuting car mileage for staff. (2006)
North Somerset Council fitted variable speed drives to the water filtration pumps at Hutton Moor swimming pool at a cost of £2,000 resulting in energy savings of £5,500 and a 4 month payback on investment. (2004)
Precision Disc Castings, Poole, met their Climate Change Levy Agreement target by reducing CO2 emissions by 1,466 tonnes in 2001/2 whilst producing 1,500 tonnes of molten metal per week at their automated foundry. (2004)
The 5 Research Councils, Swindon, implemented a major energy efficiency programme. This included the replacement of water-cooled chiller systems with high efficiency air-cooled chillers. They also removed out-dated ventilation and boiler systems, and installed VSDs (for fans and pumps) and high efficiency boilers. Evacuated solar water panels were installed for DHW. The resulting energy and CO2 savings exceeded 10%. (2008)
Rolls-Royce, Filton. Raising staff awareness, lighting upgrades, controlling motors, water leak detection, improved boiler efficiency and BMS upgrade has enabled savings of 15% on electricity, 50% on water and 30% on heating fuel - worth over £1M. (2004)
Shaw E & I, Europe, helped a major international hotel chain save over £60K p.a (= over 800 tonnes of CO2) though implementation of M&T, low energy aesthetic lighting and more proactive use of BMS. (2004)
Somerset County Council won four National Green Apple Awards in November 2006. The awards recognise best environmental practice, and the council won two gold and two silver awards for various environmental projects including waste partnership, farming and agriculture, transport, freight and highways and commerce and industry. One of the projects selected was the Somerset Biofuel Project. (2006)
South West Water's CHP plant at Countess Wear is saving £275K p.a. and the micro gas turbines at Kilmington and Totnes are together saving £35K p.a. These systems are reducing CO2 emissions by over 2,000 tonnes a year. (2008)
South West Water is "totally committed to energy management and energy efficiency and the energy management team has been reinforced since the initial accreditation [in 2001] and deliver real savings" - quote from assessor's report under the Carbon Trust's Energy Efficiency Accreditation Scheme. (2006)
Spirax Sarco, Cheltenham. Research for DETR's EEBPP into improved efficiency of steam generation/distribution identified average energy savings of: Steam distribution 8% + Steam generation 7% = 15% + resultant savings of reduced water, effluent and water treatment chemicals. (2004)
Total Lighting & Controls Ltd, Gloucester, replaced sodium lighting in a local authority’s court rooms with Inductance Luminaires. This saved over £1,000 and 15 tonnes of CO2 emissions p.a. whilst overcoming problems of poor colour rendering and slow strike-times that reduced control flexibility. The improved working
conditions also reduced staff sickness levels. (2005)
Wessex EEMG's Chairman, working under the Government's Business Resource Efficiency & Waste (BREW) scheme, identified 80% energy and CO2 savings on lighting for a retail HQ in Dorset achievable though the simple re-design of lighting controls. (2007)
Workplace Sense, Poole, assisted Bowlplex (with 16 bowling centres in the UK) to improve their 7 days a week and 16 hours/day lighting. Diachroic halogens have been replaced by 7 watt compact fluorescent lamps of the same shape (from Powertech Solar of Ferndown), hence no change to the 'atmosphere' and generating an annual saving of over £40,000 and payback in under 4 months. There are also additional
reductions in heat / aircon load. Note: Workplace Sense was one of three consultant/mentors, under the Envirowise funded Resource Efficiency Club (REC) scheme, managed by Dorset Business and supported by the South Wessex Waste Minimisation Club. The Dorset REC helped generate over £261,000 of savings for Dorset based companies in the implementation year ended November 2007. (2008)
