8 The Lower Lea Valley

9 The Olympic Park 246 hectares 220 buildings demolished 2 million tonnes of soil cleaned 30 new bridges Wetland bowl creation Sustainable drainage systems Protection of 4,000 local homes from 1 in 100 year flood event

10 One Planet Living

11 Sustainability Objectives ODA Sustainable Development Strategy Carbon Water Waste Materials Biodiversity Environmental impacts Supporting Communities Transport and Mobility Access Employment and Business Health and Well-being Inclusion

12 ODA Sustainable Development Strategy Selection of results 2 million tonnes of soil cleaned 99% demolition waste to be reused or recycled (target 90%) 60% reduction in potable water consumption (target 40%) 42% recycled aggregates (by weight) 34% recycled content of all key building materials (by value) 100% legal and sustainable timber (FSC, PEFC) 64% of materials delivered by rail or water (target 50%) 45ha of biodiverse habitat

13 LOCOG: Carbon Footprint of the Games First full mapping of carbon footprint of Olympic and Paralympic Games Forward looking impact assessment Informed carbon management strategy Focus on avoiding embodied impacts Actual footprint to be reported post-games 34% 55% ODA LOCOG Shared /Associated 11%

14 Why Legacy Is Important? Preparation Olympic and Paralympic Games Legacy 2005 One Hundred Years 2105

15 ODA Carbon & Renewable Targets Planning Obligations a reduction in carbon emissions (against 2006 Building Regulation standards) for the built aspects of the development of 50 percent by 2013 (Section 106, Schedule 11) sufficient on-site renewable energy generation capacity shall be installed to meet at least 20% of the annual carbon emissions in the Legacy phase (OD.0.21 & LTD1.3) Green Lean Mean / kg CO 2 Saved

16 Implementation Guidance for Project Teams

17 Energy Strategy Design Principles Mean: Energy efficient buildings Target: 15% Better than Part L 2006 (before low carbon heat and power)

18 Energy efficient venues Reduce primary energy demand: High performance envelope design Passive ventilation & conditioning Controls & sensors to minimise energy waste Efficient distribution of air coupled to energy recovery systems Variable speed pumping & low energy fan systems Learning Legacy: In Use Energy

19 Energy Strategy Design Principles Mean: Energy efficient buildings Target: 15% Better than Part L 2006 (before low carbon heat and power)

20 Energy Strategy Design Principles LEAN: Low carbon energy Deliver energy via low carbon technologies (CCHP) Design heating and cooling networks to minimise losses Designed with the future in mind with capacity for up to 20,000 homes in Legacy 29% reduction in carbon from CCHP Target: 20% reduction in carbon footprint using low carbon heat and power

21 Energy Centre Learning Legacy: In Use Energy

22 Energy Strategy Design Principles GREEN: Renewable Energy Park wide target (rather than venues) 2MW Wind turbine Biomass and some micro wind and PV 2 x large scale PV installations 11% renewable energy Community retrofit with the GLA - 1,300 tonnes of carbon savings per annum Target: 20% on-site renewable energy supply Target: 9% on-site renewable energy supply

23 Community Retrofit What s being delivered and where? Olympic Park Waltham Forest Home Energy Efficiency School Energy Efficiency

24 Summary Carbon Emissions Reduction 21.1% 1300 Tonnes Off Park retrofit Baseline 41.0% 4871 Tonnes Overall Saving 59% Tonnes GREEN 11.3% LEAN MEAN 29.0% 787 Tonnes 17.4% 2842 Tonnes 2071 Tonnes text goes here

25 Energy Strategy Results Comparison to 2010 Part L Building Regulations

26 Energy Strategy Athletes Village High levels of efficiency, Code for Sustainable Homes Level 4 Connection to the district heating scheme On average 80% better than 2006 Part L Building regulations

27 Other carbon targets? 40% reduction in potable water 50% of materials by rail or water 90% of waste reused or recycled Designing Out Waste Recycled Content Green Guide BREEAM Excellent, Code for Sustainable Homes L4 HFC Policy Using legal and sustainable timber Wetlands & 20ha of Green roof space

30 What about embodied carbon? 5 Key Strategies: 1. Use temporary and hired venues 2. Design for legacy and deconstruction 3. Designing out waste 4. Design optimisation / Lean construction 5. Low carbon concrete Source: WellMet Learning Legacy Paper: a breakdown of embodied carbon in construction materials
