  1. Property Group - M&E Team Renewable Energy Technologies and the Building Schools for the Future Programme Michael J Rigby M & E Team Manager Mechanical & Electrical Engineering Team Property Group

  2. Drivers for Climate Change in Construction Kyoto Agreement 121/2% reduction in CO2 emissions by 2010 UK Voluntary 20% reduction by 2010 60% reduction by 2020 EU Energy Performance Of Buildings Directive National Calculation Method Energy Labelling - ABCDEFG • Raise Awareness • Grant Funding Availability • Legislation via Part L&F of the Building Regulations UK Climate Change Program

  3. BIO-FUEL HEATING Sustainable Heating - creating and protecting jobs in rural LancashireBSF Primary Heat Source –saving 80 tonnes CO2/annum/school Leyland Wellfield HS Grant Application

  4. GROUND SOURCE HEAT PUMP Vertical or Horizontal tubes below groundBSF - Cooling to IT Suites saving 7 tonnes CO2/annum/school Heating to Ashton High School Science Laboratory

  5. Combined Heat and Power Unit Requires a constant year round electrical load and hot water demandBSF - Used in 2No. Hydrotherapy poolsCounty Records Office over 20yrs,

  6. Wind Turbines • Potentially saves 1 Tonne of CO2/annum per kW of power rating • 6kW model incorporated into each BSF school • 15kW at Ashton HS and Longridge HS

  7. PHOTOVOLTAIC DAYLIGHT AND SUNLIGHT CONTROL Ideally South FacingPanels convert sun energy to electrical energyUsed on Site or Sold back to the grid

  8. PV IS EFFECTIVE AS SHADING AND DAYLIGHT DIFFUSER Aesthetically pleasing environmentSmall amount incorporated into BSF schoolsSaving ½ tonne CO2/annum/school

  9. Solar Hot water system Ideally south facing, BSF -4m2 panel incorporated into each school Saving ½ tonne CO2/annum/school

  10. Property Group Sustainable Design Heating and Ventilation • Use of high thermal mass and solar shading to absorb heat gains, flattening peak temperatures • Natural ventilation, supporting night cooling to reducing the effects of solar gains • Heating and ventilation systems are zoned to suit building orientation, curriculum use and out of hours use. • Use of building energy management system (bems) controls. • Use of heat recovery on mechanical ventilation systems. • Use of high efficiency gas-fired condensing boilers

  11. Property Group Sustainable Design Water • Rainwater harvesting for W.C flushing and grounds maintenance usage • SUDS – Sustainable Urban Drainage Systems • Infra red sensing taps to toilet washbasins • Urinal flush controls and dual flush / low flush W.C’s

  12. RAINWATER RECOVERY • Ormskirk School 55,000 litres below ground • Equal to 10,000 toilet flushes

  13. Property Group Sustainable Design Electrical • Automatic lighting controls in teaching areas and for external lighting. • Automatic speed control of fans and pumps to match load demand and minimise energy consumption • Minimised use of electric hand driers and point of use hot water heaters

  14. Opportunities for LCC and Property Group • To lead by example • Exemplar buildings utilising leading edge technology • Low Carbon design and Sustainable architecture • Aspiring to achieve an excellent BREEAM rating • Delivering award winning Green buildings • Educational legacy, enhancing the curriculum • Research and learning tool – a living case study • Website access to allow ongoing studies of green features • Potential on site demonstrations of sustainable design and operation
