INDUSTRY NEWS Olympic green legacy takes root
With less than one year to go until the Olympic flame is lit, the environmental improvements in the Olympic Park and surrounding areas have already delivered impressive results, according to Environment Agency Chairman, Lord Smith. He highlighted five projects as key indicators of the green legacy pledge of the London 2012 Olympic & Paralympic Games, and paid tribute to those from the Environment Agency, the Olympic Delivery Authority (ODA) and other partners who have worked together to deliver on this promise.
The projects, which help to set a new
environmental precedent, include habitat creation in the form of 256 hectares (the equivalent of 276 football pitches) of land that has been transformed from a largely polluted industrial area to create areas of new green space and a haven for wildlife. In the Lower Lea Valley regeneration, the replacement of concrete walls and metal sheeting with natural banks and the removal of invasive species, such as Japanese Knotweed, is giving native plants and animals the best possible chance to flourish. Work to improve river management has also reduced the flood risk for nearly 3000 properties, virtually taking Canning Town out of the flood plain and in addition 45 hectares of the Olympic Park have been designated as species rich habitat, with reedbeds, wet woodland, grassland and ponds created to attract roosting and breeding birds, otters, water voles and amphibians.
Recycling is key
Waste management is also a key area with more than 95% of demolition material being recycled in construction on the site and more than 1.5 million tonnes of contaminated soil being treated and about 90% being reused on the site. Key to the creation of this has been the
improvement of the river banks and cleaning up the River Lea which flows right through
the site. With the help and advice of the Environment Agency, more than one kilometre of concrete walls and metal sheeting have been removed and replaced with natural banks, and 300,000 new wetland plants have been planted by the ODA with the creation of backwaters, reed beds, frog ponds and wildlife refuges. Upstream of the Olympic Park, a metre- deep layer of sediment has been removed from the River Lea, improving water quality and flow and encouraging breeding habitats for aquatic life. Through the improvements it is hoped the area will attract species including eels, grey heron, kingfisher, sand martin, bats, water voles and otters.
Different challenges
The North and South Parks have posed very different challenges in terms of delivering on the green legacy. With the focus in the North Park on creating a natural environment and habitats for wildlife, and the South Park, which is home to the Olympic stadium, needing advice and action on sustainable buildings, waste minimisation and flood risk management. This work hasn’t been limited to the main Olympic site. The Environment Agency has also carried out work at venues for rowing, canoeing and sailing to manage the water quality, and access for competitors, whilst maintaining the public right of access. Lord Chris Smith, Chairman of the Environment Agency, said:
“The
Environment Agency has worked with the ODA over the past five years to create an outstanding green legacy for the London 2012 Games.
“With less than a year to go, we have already made huge improvements to the local environment and are beginning to see wildlife thrive. Once completed, more than five miles of river and hundreds of hectares will have been created or rejuvenated, providing a refuge for wildlife for years to come.”
Life is about more than solar shading controls
Give people the tools to make savings
The National Audit Office’s judgement that smart meters may not result in a change in energy use by consumers over a sustained period has been challenged by the Energy Services and Technology Association. ESTA represents providers of energy efficiency products and services primarily to the non-domestic sector. “The experience of our members has shown time and again that once consumers can see how much energy they are using and when, they take steps to cut out waste and save money,” said Alan Aldridge, the association’s Executive Director. “Up till now the majority of energy users in the UK have not had the opportunity to make those informed decisions. Amazingly, in this day and age, most people still have to put up with estimated bills. How can anyone be expected to make rational decisions based on what is essentially guesswork?”
Major challenges
According to Alan Aldridge, the time for delay has passed: “The UK is facing major challenges in terms of ensuring security of energy supply and in containing the ever rising energy cost for business and households. The Government often states that everyone has a part to play but to engage effectively people have to be given the right information. That means accurate, real-time information which is exactly what smart metering offers.”
He argues though that the NAO’s prediction could come true if people are not told
how to use the equipment properly. “In industry and commerce, training is a key element in all energy efficiency programmes,” he says. “Without it, expensive technology can become just a box on the wall, a complete waste of money. I would hope the Government has plans in place to ensure that consumers are given help to make the most of the opportunities from this programme. Installers need to show people how to use the smart meter when they fit the units – just leaving written instructions behind will not get the job done!”
