London Low Carbon Buildings: video case studies

May 2012: Regeneration and construction experts Wilmott Dixon have posted videos on Youtube of two developments that they have been working on in London with a specific brief to reduce energy and carbon emissions. These are:

Retrofit Case Study of a London Victorian Property – a good example of the type of activity that will need to go ahead under the Green Deal in London, with extensive use of IWI (internal wall insulation) resulting in a reduction of 50% in the energy baseline of the dwelling.

Building the zero carbon ‘in use’ Crouch Hill Community Park, Islington – An update on the Crouch Hill Community Park project, developed with Islington Borough Council, which is to be the UK’s first zero carbon ‘in use’ school with a community energy centre that will also provide heat to an adjacent housing estate.

Olympics2012-Energy and Carbon Lessons Learned

May 2012: The ODA have established a learning legacy website which “has the aim to ” sharing the knowledge and the lessons learned from the construction of the Olympic Park, to help raise the bar within the sector “. Included amongst the material posted there is a number of documents relating to the energy initiatives undertaken on site at the Olympics:

The Olympic Park Energy Strategy Case Study

Energy In Use Implementation Guidance for Project Teams sets out the ODA’s requirements and the standard tools, templates and methodologies for demonstrating compliance with the carbon objectives detailed in the ODA’s Sustainable Development Strategy.

The environmental impact of the thermal insulation used at the Olympic Park, where several contractors sourced and installed insulation materials which were considered to be healthier for the operative installing the product (and potentially future maintainers) and which came from natural sources, such as plant matter or recycled material.

Reducing embodied carbon through efficient design – As the operational carbon emissions from buildings are reduced through energy efficiency measures, the embodied carbon emissions in construction materials become more significant. Two key strategies were used at the Park to reduce the embodied carbon of venues and infrastructure.

Achieving the Part L target at the Aquatics Centrethe ODA target to exceed 2006 Part L Building Regulations by 15 per cent was not included in the Aquatics Centre’s original design brief, but was instructed by RIBA – the design team successfully incorporated the requirements by focusing on the building systems and fabric improvements.

The Velodrome, the most energy efficient venue on the Olympic Park – which has a designed energy efficiency improvement of 31 per cent over 2006 building regulations.

Carbon reduction in transport management– reviews the Olympic Delivery Authority’s (ODA’s) approach to reducing the carbon impact of its transport arrangements and associated lessons learned.

All homes built on Olympic park to be zero-carbon

May 2012: The London Legacy Development Corporation has recently published a new sustainability guide for the Queen Elizabeth Olympic Park which sets out priorities against seven environment objectives which including requirements for:

  • Zero carbon homes
  • 15 per cent reduction in emissions from actual energy use by Park occupants over five years by promoting energy efficient home appliances
  • 25 per cent reduction in operational emissions over five years in venues and parklands
  • 100 per cent of homes will have smart meters to help people monitor their energy use
  • Ensure 95 per cent of visitors to events and attractions arrive by public transport, cycle or foot
  • 20 per cent of car parking spaces to have access to electric charging
  • By 2020 60 per cent of household waste should be recycled or composted compared to a London average today of 32 per cent
  • Energy efficient lighting throughout the Park

After the Games the Development Corporation will create a 225 hectare park with 102 hectares of open space, up to 8,000 homes, five permanent sporting venues, event spaces, 45 hectares of bio diverse habitat and a network of pathways, cycle routes and waterways. The document ‘Your Sustainability Guide to Queen Elizabeth Olympic Park’ can be downloaded via the following page or directly here.

Free London Mapping Tool

May 2012: From the London Datastore website:

‘Have you ever wanted to create a quick thematic map of London but lacked the GIS skills or software to do it yourself?
There is a free mapping tool from the GLA Intelligence Unit that allows the user to input their own borough data to create an instant map that can be copied over into Word or another application of their choice. More information and the tool itself can be found here.’

May 2012: The first of  three 2 MW Combined Heat and Power (CHP) engines  for the 67 acre King’s Cross Central development has been installed at the on-site energy centre. In total the CHP capacity when finally installed will supply 100% of the development’s heat and offset almost 80% of its electrical power demand. The news release sets out that “Once commissioned, the CHP engine will not only generate electricity, which will be fed into the grid network, but will also provide heat for the development wide District Heating System (DHS). All of the 70 buildings at King’s Cross, from the University of Arts to the Camden Council building, BNP Paribas Real Estate’s new offices and the Great Northern Hotel, will be connected to the DHS When complete carbon emissions are expected to be a third less than ‘business as usual’ and up to 60% less than 2001 levels.”

Further information on the energy strategy for Kings Cross central here and main energy assessment (as set out for the planning application in 2005) can be downloaded here.

‘Councils can lead green deal’

May 2012: Article highlighting work undertaken by the Association for Public Service Excellence setting out that “central government must unlock local authorities’ potential to develop the green economy as a matter of urgency…Local authorities should also have greater financial freedom to boost the green economy. For example, they could offer council tax rebates to households that reduce carbon usage. This could be complemented by a tax exemption on low-carbon regeneration projects that are financed through municipal bonds. The exemption would be a temporary measure to stimulate green growth until the UK economy fully recovers.

Other measures outlined in the report include requiring the electricity industry to work on district energy planning and making Feed-In Tariffs viable for large-scale social housing schemes.”

‘London to test ‘smart city’ operating system’

May 2012: BBC News story reporting that “An operating system designed to power the smart cities of the future will be put through its paces in London. With partners including Hitachi, Phillips and Greenwich council, it aims to use the Greenwich peninsula as a testbed for new technologies running on the system. The OS aims to connect key services such as water, transport, and energy.”

Further information is available on Living Plan IT’s website which states “The Urban Operating System (UOS™) is the core technology platform that will manage vast amounts of data across cities and urban spaces and thereby facilitate smarter, sustainable and intelligent-living. This, in turn, will lead to more efficient use of energy and other resources, providing the basis for innovative services for residents, businesses and governments as well as new jobs and exports.”

How London compares to other leading cities on carbon/energy

May 2012: The World Bank have just published a report which focuses on Chinese cities and the need for these areas of growth to respond to the challenges of climate change. The report however also provides a comparison of London against a number of other world cities, looking at a range of low-carbon metrics (emissions per capita, CO2 intensity, energy consumption per capita and so on – see Tabl3 3.1 – pg 85) which may be of interest. The World Bank news story around the release of the report is available here, and the report itself – Sustainable low-carbon city development in China – can be downloaded here.
