Urban Green Infrastructure

15 November 2013: The Parliamentary Office of Science & Technology has just produced a short briefing note on ‘Urban Green Infrastructure’ which “summarises research evidence of the effectiveness of green infrastructure, and challenges to its implementation.” It includes reference to ‘cooling  the urban heat islands‘ stating:

“Urban areas often experience elevated temperatures compared with the surrounding countryside, because of extensive heat absorbing surfaces, such as concrete and tarmac, concentrated heat production and impeded air flow. For example, the centre of London is on average 5°C warmer than surrounding rural areas.

Barking & Dagenham most energy efficient local authority in UK

November 2013: A news release from Imperial College highlights a recent study examining the energy consumption of all 198 urban local authorities in the UK, including 33 boroughs in London.  Dr James Keirstead has developed a “new method that draws on three different measures of energy efficiency, currently used by city planners, to create the ranking. The aim was to find the fairest methodology for determining energy efficiency that could give planners an improved way of spotting best practice, leading to more energy efficient and sustainable policies in the future.”

“The London boroughs of Barking and Dagenham and Hackney topped the league table of all UK urban areas analysed in the study…This may be because both are low income areas, equating to lower energy usage. Residents of those areas are also more reliant on public transport and these boroughs lack energy-intensive manufacturing and commerce, which may also be other factors that explain why consumption is lower.”

The news report is a very short summary of a detailed research paper published by Dr Keirstead in technical journal Energy Policy (which unfortunately has a price tag associated with downloading the paper). The table from the paper providing a ranking of UK local authorities by average energy efficiency score is reproduced below:

Other London boroughs within the top 10 are Hackney, Merton, Redbridge and Kingston. Oddly, the top two ranked London councils are both within inner London, however, the remaining three in the 10 are all suburban local authorities.

Local authorities in England have now reported to Government on energy efficiency activities in their area in HECA update reports – for more of which, see here.

DECC HECA Research

November 2013: All English local authorities were required to submit an updated Home Energy Conservation study report to DECC by 31 March 2013. An earlier post goes into these requirements in more detail and provides links to the report from those London boroughs who had posted them online on their website.

DECC have now published research summarising around 245 of these reports (see the Excel spreadsheet on the following link) as well as a document providing links to all reports published online. See both here. Only 20 London boroughs reports are however summarised on the spreadsheet. The HECA list states that some London boroughs have still not submitted reports: these appear to be Barking & Dagenham, Brent, Lambeth and Southwark.

It’s unclear if Bexley, Islington and Merton have submitted reports, as no links are listed – though the list does not say explicitly set out that these reports have not been provided: however, their actions are also not summarised on the spreadsheet.

GLA district energy research commissioned

November 2013: The GLA have commissioned research into how district heating systems can work successfully in new developments as energy efficiency requirements continue to increase. The approval document sets out that:

“With the improving standards for insulation and air tightness to retain heat within developments, it is important that communal heating systems within buildings are designed so that they do not contribute towards buildings overheating.

“It is therefore proposed to procure consultants to carry out a study into how communal heating systems, specifically in residential schemes, implemented as a result of policy can be designed to avoid overheating.”

This issue of district heating and overheating was briefly touched upon in research undertaken by AECOM for the Department of Communities in 2012.

Innovative Kingston heat pump scheme

November 2013: Local MP and Secretary of State for Energy, Ed Davey, recently opened a novel heat source pump scheme providing heating to a residential scheme in Kingston drawn from the Thames.   An article in Renewable Energy Installer sets out that “Just 200 metres from the river bank, its 2.3MW community heating system draws up to 13 million litres of water each day through high efficiency heat exchangers. The low grade heat is carried to a plant room in the building via a closed loop where Mitsubishi Ecodan heat pumps delivers it as usable heat to meet all heating and hot water demands in the complex.”

A huge amount of background detail to this novel scheme can be read in trade journal Modern Building Systems here. Mitsibushi have described the scheme as “one of the most impressive in Europe if not the world. This is a pioneering installation and hugely innovative.”

Fuel Cells in London

November 2013: The Guardian highlighted in a recent story that the London HQ of Al Gore’s business is to be based in a new office development on Regent Street which has included a wide array of onsite energy measures installed including a gas-powered fuel cell.

“Climate campaigner and former US vice-president Gore said the £400m Quadrant 3 redevelopment showed a “sophisticated commitment to sustainability”. The headquarters of his sustainable investment company, Generation Investment Management, will be sited in the new buildings.

“The cell was developed by US company FuelCell Energy. It will emit 38% less carbon dioxide than using electricity from the grid and heat from gas-fired boilers, according to the crown estate, which says 350 tonnes of carbon dioxide emissions will be saved per year. Unlike fossil-fuel-burning power plants, the fuel cell produces power with virtually no nitrogen oxide (NOx), sulphur dioxide (SOx) or particulate matter (PM) pollution.
The new plant forms part of the central energy system that serves 500,000 sq ft of offices, shops, flats, restaurants and hotels in the Quadrant development.” Read the full Guardian story here.

Further detail on the installation of the fuel cell can be read here – which has been undertaken by Edinburgh based Logan Energy. The Quadrant 3 development has a number of other onsite energy measures installed (including a Combined Cooling Heat & Power plant, thermal stores and photovoltaics – see diagram below), as set out in the property brochure.

Another new London development to include fuel cell technology is that on 20 Fenchurch Street (more commonly known as the ‘Walkie Talkie’ building) which has installed a 300 kWe fuel cell, details of which can be read here and here.

Transport for London installed a fuel cell CHP in their Palestra building in Southwark back in 2010, details of which – including a video presentation – can be seen here and here.

Brixton Energy on the Beeb

November 2013: The recent BBC London coverage of the Brixton Energy solar schemes can now be viewed on Youtube here.  The new piece includes interviews with Brixton Energy and Repowering London Director Agamemnon Otero and Labour Council Leader of Lambeth, Lib Peck.

Cllr Peck states in her interview that local authorites should be looking to work on similar projects in their own areas but it will be about the will of councils to say they want to make these projects happen and get rid of the challenges and obstacles.

Reducing building CO2 emissions through better design

November 2013: The GLA have commissioned research to determine the “most effective way for buildings to reduce their carbon dioxide emissions through the design and fabric, based on the Building Regulations modelling tools.” This study will support the GLA’s recent Supplementary Planning Guidance on Sustainable Design & Construction guidance (for more of which here) and London Plan targets which requires all major planning applications from 1 October 2013 will need to provide CO2 emission savings 40% beyond the 2010 building regulation requirements.

Potential for biodiesel from use cooking oil and FOGs in London

November 2013: The Mayor announced today that TfL will be deploying 12o buses from the Barking depot which will run on a blend of 80 per cent regular diesel and 20 per cent biodiesel. The press release states that “Biodiesel is a renewable, clean-burning fuel made from used cooking oil from the catering industry and tallow which is a residue from the meat processing trade. It is estimated that buses running on biodiesel produce 15 per cent less ‘well to wheel’ carbon emissions than an ordinary diesel-powered bus…No mechanical change is needed to allow a bus to run on a 20% blend of biofuel. The biodiesel in this trial is being supplied by Argent Energy with the standard diesel supplied by Prax Petroleum.”

The GLA also commissioned consultants LRS to produce a report on the market opportunity for a biodiesel market in London using used cooking oil (UCOs), fats oils and grease (FOGs) from commercial and domestic sources in the capital. The report can be downloaded here and sets out to “evaluate the potential to reduce the emissions and carbon footprint of the bus fleet in London by using up to B30 biodiesel instead of petrodiesel. Additional sustainability benefits would be achieved by using biodiesel made from used cooking oil (UCO) and fats, oils and greases (FOGs) instead of virgin oils.”

The report references recent disputes in London over UCO (see Daily Telegraph story here) stating “only 3-4 years ago illegal disposal of UCO down drains was recognised to be a significant issue, recently the demand for UCO has soared and led to ‘Cooking Oil Wars’, whereby collectors pay increasingly escalating prices to commercial organisations for UCO.”

In terms of London’s potential to produce biodiesel, on the basis of national estimates, the report suggests that using the “ratio of London’s population to the national population and uplifting to reflect the greater concentration of catering establishments in London gives an estimate of 32-44 million litres of UCO waste arisings in the London area. There are nearly 24,000 food and beverage service activities in London, along with a further 835 businesses in London working in the food manufacturing sector, most of which contribute to the production of UCOs. In particular London has over 8,000 fast food outlets, with some of the highest concentrations of such food outlets in the country.”
Lot of interesting findings in this comprehensive report. More on biodiesel use in London here.
