CRed carbon reduction HSBC Sustainability Audit Report • General Information and background theory • Methods to analyse data and present results. • Cambridge • Norwich • Great Yarmouth • UEA • Kings Lynn • Comparisons • The Toolkit & Recommendations
CRed carbon reduction HSBC Sustainability Audit Report • General Information • Background Data is problematic • not clear which readings are estimates • not clear on which day of month readings were taken
CRed carbon reduction HSBC Sustainability Audit Report Thermal Comfort • Thermal Comfort is an Individual Perception • Depends on: • Air Temperature • Mean Radiation Temperature • Wind Speed (usually not an issue for indoor environment except where there are draughts) • Humidity • Clothing Level • Activity • If Working Environment is either too hot or too cold then productivity is affected. • For every 1 deg C change in temperature ~ 8% change in energy and carbon emissions
CRed carbon reduction HSBC Sustainability Audit Report Thermal Comfort Temperatures were often 23oC higher than legal thermostat level Short sleeved shirts were common This branch had no temperatures above 22oC No short sleeved shirts were seen
CRed carbon reduction HSBC Sustainability Audit Report Thermal Comfort +3 very hot +2 hot +1 warm 0 neutral -1 cool -2 cold -3 very cold Thermal Comfort is measured on ASHRAE Scale Perception can also be predicted 25% of Staff at Cambridge Office were surveyed four times a day for one week
+3 very hot +2 hot +1 warm 0 neutral -1 cool -2 cold -3 very cold CRed carbon reduction HSBC Sustainability Audit Report Thermal Comfort • Clothing Levels were low at Cambridge • Mean Temperature was 23oC • Survey Mean Vote of ~ -0.04 is almost optimum for that level of clothing • If clothing level were increased – equivalent to moving from short sleeve to long sleeve shirt – temperature could be reduced by 1oC for same level of comfort • 1oC temperature drop >> 8% saving • Mean Temperature at King’s Lynn was 220C and staff were not wearing short sleeve shirts
CRed carbon reduction HSBC Sustainability Audit Report Monitoring Performance – Gas • Norwich Branch • Identify when consumption deviates significantly from trend line
HSBC Sustainability Audit Report Monitoring Performance – Gas CRed carbon reduction Kings Lynn Branch Upper and Lower bands can be used to identify problems and aspects of good practice
Target Day CRed carbon reduction HSBC Sustainability Audit ReportRaising Awareness • General Lack of Awareness of what energy consumption is or what could be done. • Some staff would welcome feedback UEA Switch off Campaign April 2005
CRed carbon reduction HSBC Sustainability Audit ReportRaising Awareness • Some staff mentioned difficulty in turning off appliances • Crawling under Desks • PowerGenie could help C A B
X22 CRed carbon reduction HSBC Sustainability Audit ReportCambridge Area Office • Recently moved into office • No Data available • Estimate of Lighting and IT use
A B C CRed carbon reduction HSBC Sustainability Audit ReportCambridge Area Office • Some staff commented on lack of day-light – blinds were drawn. • Survey indicated lighting was slightly on bright side • Little opportunity for control • Three tubes in each fittment • Opportunity exists for rewire • Group A & C together and B separately • Three levels of lighting • B • A & C • A, B & C
CRed carbon reduction HSBC Sustainability Audit ReportCambridge Area Office • Waste: Recyling Bin was locked – minimising contamination • Coffee machine on first floor casing was quite hot – unlike those at other branches
X137 CRed carbon reduction HSBC Sustainability Audit Report Norwich Branch Summary • Gas consumption is less than electricity consumption • Electricity consumption is high for an office building
CRed carbon reduction HSBC Sustainability Audit ReportNorwich Branch and Office • Most lights in foyer had two bulbs • Many not working • Better wiring system could save energy Located in Pedestrian Precinct
CRed carbon reduction HSBC Sustainability Audit ReportNorwich Branch and Office Three of the offices at Norwich Similar lighting to Cambridge is evident Groups of 4 tubes
overnight weekend overnight CRed carbon reduction HSBC Sustainability Audit ReportNorwich Branch and Office • Cost Plug monitoring computer use • Not always switched off
CRed carbon reduction HSBC Sustainability Audit ReportNorwich Branch and Office - Electricty Nearly double early 2005 level 33% higher than historic level Cost increase ~ £10000 - £12000 pa CO2 increase ~ 100 tonne pa Appears to be associated with malfunction of air conditioner Electricity Consumption improves in 2004 ? Implementation of conservation measures Sudden jump in consumption
CRed carbon reduction HSBC Sustainability Audit ReportNorwich Branch and Office - Gas Gas Consumption is relatively low Extensive use of fixed and free standing electrical heaters Double carbon dioxide emission when heating with electricity
CRed carbon reduction HSBC Sustainability Audit ReportNorwich Branch and Office • Several rooms which were not in use had lights on • Air-conditioning unit was fully on in training room even though no one was there on one occasion • Floor 3 and 4 offices could make better use of natural daylight • Better awareness could lead to a saving of 20 – 25 kWh per day from lighting or a saving of up to 2.5 tonnes of CO2 per year. • Switching to flat screens could save up to a further 7.5 tonnes CO2 • Greater savings would be achieved by attending to malfunction of heating and air-conditioning units. However, many functions of Branch may be moving to a new location within the year.
X35 CRed carbon reduction HSBC Sustainability Audit ReportGreat Yarmouth Branch
CRed carbon reduction HSBC Sustainability Audit ReportGreat Yarmouth Branch Building is in poor state of repair Dampness evident in many places
CRed carbon reduction HSBC Sustainability Audit ReportGreat Yarmouth Branch Dampness is affecting many rooms Power leads for Training Room have to be brought in from corridor for equipment.
CRed carbon reduction HSBC Sustainability Audit ReportGreat Yarmouth Branch Blinds are a problem. The blue colour matches furniture but absorbs heat. Glare occurs if blinds are opened
CRed carbon reduction HSBC Sustainability Audit ReportGreat Yarmouth Branch Electricity Consumption Limits suggested at +/- 2000 kWh Lighting and IT accounts for ~ 60% of electricity use No seasonal trend – lights on all the day Variation due to estimated readings or readings not on same day of month
CRed carbon reduction HSBC Sustainability Audit ReportGreat Yarmouth Branch - Gas Values in Red appear spurious – probably estimates or values over short months Spurious points plot way outside normal trend line Bandwidth is +/- 4000 kWh / month
CRed carbon reduction HSBC Sustainability Audit ReportGreat Yarmouth Branch • The major problem with this building is its general physical condition and this may be responsible for part of the energy use. • The coloured blinds are increasing solar gain in summer and thus increased use of air-conditioning. • There are Health and Safety issues associated with the dampness and use of trailing leads when the Training Room is used
X28 CRed carbon reduction HSBC Sustainability Audit ReportKings Lynn Branch
CRed carbon reduction HSBC Sustainability Audit ReportKings Lynn Branch • The Kings Lynn Branch is in the Pedestrian Precinct • A few spot lights are unnecessary
CRed carbon reduction HSBC Sustainability Audit ReportKings Lynn Branch • The downstairs office • Unlike other offices some unused computers were switched off. • Thermostatic radiator valves were at different levels suggesting staff were adjusting them to suit needs • Control of air-conditioning etc in main office is confusing and few staff know how to operate it
CRed carbon reduction HSBC Sustainability Audit ReportKings Lynn Branch • Upstairs office • No short sleeve shirts: Temperature ~ 1oC cooler than other branches • Conference Room – not in use at time • Lights off • Temperature 3 oC cooler than rest of building • Prominent Thermometer near door and temperature control
CRed carbon reduction HSBC Sustainability Audit ReportKings Lynn BranchElectricity Consumption Proactive response to switching off unnecessary lights. No unoccupied room had lights on Store rooms Conference room Kitchen / rest area Lowest consumption per employee
CRed carbon reduction HSBC Sustainability Audit ReportKings Lynn Branch - Gas Note: Spurious readings again Bandwidth is +/- 4000 kWh / month
CRed carbon reduction HSBC Sustainability Audit ReportKings Lynn Branch • Good control of lighting and heating at this Branch • Proactive approach by manager to check unnecessary lights etc are off. • Saves around 3500 kWh per annum • 1.9 tonnes of carbon dioxide • £200 – 250 per annum
CRed carbon reduction HSBC Sustainability Audit ReportQuality of Data Kings Lynn Great Yarmouth Note Spurious data occurs in exactly same months and by same order of error.
CRed carbon reduction HSBC Sustainability Audit ReportElectricity Consumption (kWh/m2) Annual Household consumption of Electricity in Norwich 3720 kWh
