Buildings over one hundred years old account for about 5% of the UK's total greenhouse gas emissions, but how do you reduce their carbon footprint without undermining their historical value? Heritage Counts 2008 is the seventh annual survey of the state of England’s historic environment. This year there is a focus on climate change and its impact on the historic environment.
This is the question that has been plaguing English Heritage, the National Trust and others involved in the preservation of ageing buildings.
In their annual report, Heritage Counts, the organisations have turned their attention to sustainability, recognising that older building might be less resilient to the ravages of climate change than those built in more recent years when the risks are known from the design stage.
The report calls on the Government and local authorities to recognise that the historic environment is part of the solution to tackling climate change and that its share of carbon emissions can be reduced by sensitive improvements.
Statistics shows that houses in England built before 1919 account for approximately 5% of all the country's carbon emissions.
Speaking at the launch at the London Transport Museum, Sir Barry Cunliffe, interim chairman of English Heritage, said: "The nation's built heritage is a finite and precious resource and we must recognise that the re-use and recycling of older buildings is both responsible and sustainable.
"Although some older homes are currently less energy efficient than some newer ones, solutions do exist to make them more energy efficient. Rising to this challenge, however, demands care.
"We need to develop and share approaches that avoid unnecessary damage to the special value and qualities of the historic environment.
"More Government policies that work towards changing human behaviour in energy use are also necessary because that is the area that will make the crucial difference."
Fiona Reynolds, director-general of The National Trust said: "The historic environment is often amongst the first to experience problems associated with climate change and, just like any other home, work or meeting place, older buildings can be an important part of the solution.
"Every little contribution we can make to cutting carbon use can make a real difference.
"From renewable energy generation through to improving energy efficiency, Heritage Counts gives a compelling picture of how older buildings can be sensitively adapted to make a positive contribution.
"Moreover, they can inspire millions of people who visit historic properties to take action themselves. We call on the government to recognise the valuable role the heritage sector can play, and is playing, in tackling this urgent problem."
Heritage Counts 2008 (click for full report) emphasises the active role heritage organisations can play to help society pursue a low carbon economy - from mitigating the share of carbon emissions produced by historic buildings through advocating measures to improve energy efficiency of older buildings, championing and experimenting with new technologies on historic properties they manage to inspiring the public to change their behaviour on energy consumption.
Conwy County Borough Council has backed plans for a pilot tidal energy scheme off the North Wales Coast.
The £150 million scheme at Llanddulas in North Wales would provide a testing facility for turbine designers and manufacturers, and assess the environmental impact of turbines.
The project was given approval by the council as part of a strategic regeneration strategy for the Conwy coast, prepared by consultant Capita Symonds.
Paul Terry, Capita Symonds, said: "Tidal power will play a key role in providing a sustainable energy source for future generations. The North Wales coast is an ideal place for such a scheme as it’s blessed with a good tidal range and suitable ocean depth." He added that the project could also help protect the coast from rising sea levels, storm surges and coastal erosion.
The regeneration strategy also calls for seven new visitor centres costing £30m should be built at key locations stretching from Conwy to Rhuddlan. But North Wales Tourism chairman Chris Jackson raised doubts over whether the proposals could realistically be funded in the current economic climate. The council’s approval now means that Capita Symonds will seek funding for feasibility studies and investigations to develop a business case for the scheme.
Climate Change Minister, Greg Barker, has launched a consultation on the Government's strategy to boost energy self-sufficiency in communities.
The public debate about microgeneration will look at ways to ensure the quality of generating technology and its installation, how to improve available products, and how to develop the microgeneration supply chain while providing more accessible advice.
The consultation follows last week's news that the Government is to overturn a ban on councils selling "green" electricity back to the national grid by the end of the year.
Mr Barker said“I want to see more homes, communities and businesses generating their own energy. We can literally bring power back to the people.Microgeneration is a key part of this vision.
“By becoming more self sufficient we can create sustainable local energy economies. People and communities can save money on their fuel bills at the same time as generating an income and cutting carbon. I want to work with industry to overcome the challenges it is facing. Together we will create a marketplace for jobs and prosperity alongside products and advice which people trust.”

A report from the think-tank Civitas warns that the increasing cost of energy, which has been driven up as a result of green policies could hit the UK's manufacturing sector - just as the country needs industry to help boost the economy.
The report said efforts to tackle climate change through cutting greenhouse gas emissions and increasing renewable energy generation could significantly push up energy bills for business.Extra costs are put on energy from policies including the EU's emission trading scheme, the renewables obligation to boost investment in technology such as wind power, and the climate change levy which taxes energy use in businesses and the public sector. Also, the Labour Government's climate change strategy had already added an extra 14% on homeowners' electricity bills and 21% on business bills.
Last year's renewable energy strategy could have created "surcharges" of up to 70% for businesses, and 33% for domestic customers by 2020, the report from Civitas claimed. The study warns the new coalition Government's energy policy could be as damaging to manufacturing industry as the previous administration.
The review by economist Ruth Lea and Jeremy Nicholson, director of lobbyists the Energy Intensive Users Group, said the UK was badly placed to meet its commitments to boost renewables as it was starting from such a low base. Even without the extra costs imposed to pay for climate change policies, Britain has high industrial electricity prices, which threaten its competitiveness.
Ms Lea said: "The economy desperately needs a competitive and thriving manufacturing sector if it is to prosper. Competitive energy prices are vital to the success of manufacturers, especially energy intensive users.Government energy policies are, however, remorselessly driving up energy costs thus risking the 'migration' of manufacturing plants to economies where the costs are lower."
