Why a special plan?
• Europe’s biggest city • 1,572 sq. km • 7.56 million people • Forecast to grow to 10 million by 2031 • Plan for integrated framework
Six key objectives 1) Meet the challenges of growth sustainably 2) Create a globally competitive city 3) Diverse and strong community 4) Great buildings and architecture 5) World leader in supporting the environment 6) City that is accessible via good public transport
About the plan • 121 policies • Over 300 pages • Updated end of 2013 • Ensures joined-up policy • All Boroughs must adhere to it
The plan and construction • Background to all planning • Sustainable development is central theme • Mitigating effects of climate change • Lifting people out of fuel poverty
London and climate change UK capital is vulnerable to climate change, through: • Flooding • Subsidence • Water shortages • Overheating All are more likely to happen….
The City – good and bad for the environment • 167 litres of water per person, per day • Energy demand growing • More public transport use • Lower carbon emissions
GLA targets • Reducing carbon and emissions • Improve energy efficiency of London’s homes • 60% reduction in CO 2 by 2025 • Deliver 25% energy from decentralised sources by 2025
Lean, clean and green Development Plan Documents (DPDs) 1. Does the proposal use less energy by adopting sustainable design and construction measures?
2. Does the proposal use an efficient energy supply, with particular emphasis on de-centralised energy generation?
3. Does the proposal use renewable energy?
Other important factors • Effective adaptation • Minimise overheating • Reduce heat island effect • Minimise solar gain and water use • Reduce flood risk
Energy in the Plan • Energy assessment • How CO 2 targets will be met?
• 40% improvement on Part L 2010 • 2019 – non-domestic zero carbon buildings
Existing stock – the main factor • RE-FIT scheme – Retrofitting existing public sector building stock • 40% refitted by 2025 • 11 million m 2 • Save 2.5 million tonnes of carbon per year
London homes • RE-NEW for homes • Maximise funding from the Green Deal • Maximise funding from ECO • Energy saving investments
New approaches to heating • No single solution to London’s challenges • Mayor supports innovative approaches • Renewables must be considered for projects • Heat pumps, photovoltaics, solar hot water
Decentralised energy and Secondary heat
Decentralised energy:
by 2030 almost 25% London’s heat could be locally generated
Secondary heat sources:
Waste heat from industrial and commercial activities. Naturally occurring heat in the air, ground & water
The potential of heat pumps • Waste heat not uniform • Need to lift temperatures • Heat pumps could achieve this • Heat pumps proven technology – 25,000 homes
A vision of low-carbon heating • London in 2050 • Move away from fossil fuels • Secondary heat sources in the city centre and outskirts • Heat pumps important technology • Variety of capacities to suit
Using a range of available heat • Heat pumps access heat from air, water and ground • Need to invest in building stock • Improve energy performance then use renewables • Heat pumps can do a lot to support the London Plan
Movement of heat • Movement of heat between buildings through low temperature heat loops • Opportunities for heating and cooling • Heat not lost – re-used • Higher temperature waste heat or loops can interact with low temperature loops • Vital to realising change
Case study for London • Kingston Heights • £70 million mixed use development • Former power station next to the River Thames • 56 affordable homes • 81 luxury apartments
Using Heat from the river • All homes benefit from cutting-edge heat pump system • Harvests naturally stored energy from the River Thames • Community heating scheme based on heat pump technology
