  1. CranbrookA zero carbon case study 10th July 2012 Mike Wood Centre for Energy and the Environment

  2. The Centre for Energy and the Environment E Energy, environmental and climate change policy Building performance modelling Sustainable and energy efficient buildings Sustainable transport Renewable energy systems Waste Research and knowledge transfer

  3. The Centre for Energy and Environment • Climate change and energy policy • Audits of local energy use • Audit of greenhouse gas emissions • Support for carbon reduction strategies • National carbon and energy policy drivers • Local evidence bases and wording • Sustainable buildings • Advice on sustainable design and policy • BREEAM assessments / advice • Building Energy Certification • Day lighting simulations and calculations • Energy auditing • Built environment performance monitoring • Monitoring of building services performance • Ventilation measurement and CFD prediction • Acoustic design advice for buildings • Measurement of the acoustic quality of buildings • Sustainable transport • Local air quality assessments and modelling • Low carbon transport technology and fuels • Carbon reduction strategies • Renewable and low carbon energy systems • Renewable energy feasibility studies • Technology evaluation • Low carbon development policy and advice • District heating and ESCos • Waste • Energy from waste • Waste studies • Research and knowledge transfer • Climate change and adaptation • Knowledge transfer partnerships (KTPs) • Bespoke research

  5. Heat and electricity demand in the UK

  6. Economies of scale – Cranbrook 2008 Bio-boiler District heating with gas CHP District heating with biomass CHP Source: Element Energy, July 2008

  7. Cranbrook DH & CHP breakthroughs 2010 • £4.1m HCA low carbon infrastructure grant • Private sector ESCo proposition • Renewable Heat Incentive (RHI) • Skypark commercial development included in scheme

  8. Cranbrook & Skypark Energy Solution Image courtesy of eon District heating Homes and commercial buildings connected by 75 km of heat pipes • Energy Centre • 1.4 MWe natural gas CHP units and five 4 MWth Natural Gas boilers • Two advanced thermal gasification units linked to two 1.4 MWe CHP engines • Thermal stores • Output Capacity when fully operational 4.2 MW electricity and 25.4 MW heat • c 13,000 t /year CO2 savings per year

  9. Cranbrook & Skypark scheme benefits • Reduce developers exposure to tightening CO2 standards at little extra cost • Demonstration of a private sector ESCo model • Biomass CHP using recycled wood • ~£45m low carbon investment Image courtesy of St Modwen
