zero carbon Britain ??

Following on from yesterdays post on the Lib Dem’s vision for a zero carbon Britain… one with no fossil fuel cars and a zero carbon built environment by 2050 -Leo Hickman considers the implications in today’s Guardian and rightly points out that the Lib Dems may have stolen the clothes from the other parties, albeit temporarily.

Are we seeing a rising in the ante of carbon  politics? along with a new zeitgeist of green taxes and green mortgages?

The fight is has commenced for the greenest party.  One wonders where the Green Party will position itself, or has it achieved its aim of bringing green issues to the top of the political and corporate agendas?

the real cost of green building?

A recent report identified high levels of awareness of the issue of sustainable building but low levels of specific knowledge and involvement. It identified three key barriers to addressing energy efficiency in buildings

Lack of information about building energy use and costs
Lack of leadership from professionals and business people in the industry
Lack of know-how and experience as too few professionals have been involved in sustainable building work.

Phil Clarke reported in Building earlier this week:

Study finds professionals misjudging sustainable budgets and underestimating carbon footprint of buildings

Construction and property professionals are overestimating green construction costs by 300%, a new survey has found.

From their press release:

Survey finds green costs overestimated by 300% and a need to foster zero net energy construction. Key players in real estate and construction misjudge the costs and benefits of “green” buildings, creating a major barrier to more energy efficiency in the building sector, a new study by the World Business Council for Sustainable Development (WBCSD) reports.

Respondents to a 1400 person global survey estimated the additional cost of building green at 17 percent above conventional construction, more than triple the true cost difference of about 5 percent. At the same time, survey respondents put greenhouse gas emissions by buildings at 19 percent of world total, while the actual number of 40 percent is double this.

Comment

Of interest within the report, after a quick scan are:

The EEB vision is a world in which buildings consume zero net energy

Use less, make more, share There are three key elements to achieving zero net energy:
• Use less energy
• Make more energy (locally)
• Share surplus energy (through an intelligent grid)

An Integrated Design Process (IDP) involving all participants in the early design phase of the project.

Behavioral, organizational and financial approaches to overcome barriers:

Encourage interdependence by adopting holistic, integrated approaches among the stakeholders that assure a shared responsibility and accountability toward improved energy performance in buildings and their communitiesMake energy more valued by those involved in the development, operation and use of buildings

Transform behavior by educating and motivating the professionals involved in building transactions to alter their course toward improved energy efficiency in buildings.

Understanding the Merton rule…

There has been a lot of coverage on the Merton Rule this week, with zero champion over at sustainability blog covering events.  here  and here  now, a further article in today’s Guardian attempts to clarify … or not.

Why is this important?

The so called Merton Rule wa introduced by Merton Borough and requires, as a planning requirement, that all new projects to obtain at least 10% of a building’s energy from sustainable sources such as solar or wind power.  The rule is now used by 150 councils across the UK, many using the 10% figure others, like GLA attempting to push for 20%.

A recent and current campaign by the British Property Federation and Home Builders Federation to overturn this ruling led to leaks of a draft planning policy statement which local authorities said would undermine their ability to insist that developers use green technologies.

Meanwhile – an epetition has been started… We the undersigned petition the Prime Minister to Not allow the abolition of the Merton Rule. There are 51 signatories so far.

Construction work prices to soar 34% over next five years

From today’s Building daily news :

Rise in PFI and Olympic works will see tender prices grow 2.5 times faster than inflation says report

The price of construction work is expected to surge ahead of inflation over the next five years.

Tender prices are forecast to rise 34% compared to an expected inflation rate of 13%, according to a report published by BCIS.

climate change? … dont worry we have a cunning plan … the moon

If we carry on, business as usual, not making the carbon and environmental targets within the timespan  scientists tell us we must act withi, then all is not lost.  There is another nearby planet we can start all over again on according to the National Geographic Website

 ‘Lunar Ark’ Proposed  August 14, 2007

The moon should be developed as a sanctuary for civilization in case of a cataclysmic cosmic impact, according to an international team of experts.

NASA already has blueprints to create a permanent lunar outpost by the 2020s

Only local labour and material resources to be used?

Expressions of interest for the design, construction and facilities management are invited.

carbon offsetting targeted … again

Interesting to see that the Climate Change Camp at Heathrow targeted carbon off setting companies in their recent protests. And quite rightly so, useful as chocolate teapots, carbon offsetting schemes distract from real actions to address environmental and carbon issues, and foster a ‘do nothing different’ attitude.  (Even for  LA trying to achieve zero carbon homes by paying £200 a home to a carbon offset scheme)

From today’s Guardian  

Two carbon offset firms staffed by committed environmentalists also found themselves targeted. Climate Care in Oxford was invaded by people dressed as red herrings and the CarbonNeutral Company in London was leafleted. Both offer to “neutralise” the emissions of consumers and companies by investing in projects which lower emissions elsewhere.

“Carbon offsets are ineffective, based on dubious science and lead people to believe they are helping when they are not,” said Sophie Nathan, who took part in the CarbonNeutral Company action.

Builders attack green homes rule

Reported on Guardian Unlimited today:

Housebuilders are trying to persuade the government to ditch a key policy designed to cut carbon emissions through constructing green homes.

Britain’s renewables industry and many local authorities are concerned that intense lobbying may have persuaded the government to rethink.

It is assumed the housebuilders in question do not include those commiteed to the 2016 Commitment to zero carbon housing (see Communities and Local Government website)

Time to commit

2016 Commitment

Housing minister Yvette Cooper has urged house-builders, councils, and others to sign the 2016 Commitment to zero carbon housing.

More details on the Communities and Local Government website

List of signatories can be downloaded from here. A quick scan shows some 100 plus signatories to date – but none from the north west??

Time to make that commitment to working together and addressing the 2016 target challenge

at last … low cost solar power that works in the (Welsh) rain…

Excellent article in today’s Guardian reports on the innovative approaches being taken by G24 Innovations in Cardiff to revolutionise solar power panels.

This is just the innovation that the drive towards green, self generated energy for the built environment needs.

… those behind the Welsh operation think they may have made a crucial breakthrough. Their solar cell works in a different way from most, and is not based on silicon – the expensive raw material for conventional solar cells. G24 Innovations (G24i), the company making the new cells, says it can produce and sell them for about a fifth of the price of silicon-based versions. At present, it makes only small-scale chargers for equipment such as mobile phones and MP3 players. But it says larger panels could follow – large enough to replace polluting fossil fuels by generating electricity for large buildings.

and the applications could be wide ranging, with many safety related uses on building sites…

Design students have also been involved with the development process. Earlier this year, the company ran a competition with 45 product design students at St Martin’s college of art and design in London, who were asked to think up new uses for the Cardiff solar cells. The winning entries include portable safety lights mounted on life buoys, and lamps to mark scaffolding and hoardings around roadworks and on building sites. They also featured solar-powered security lights, fire exit signs, and window blinds, which could cut electricity use.

and addresses the social, global need for energy

The first commercial uses are likely to be in the developing world, where access to electricity is difficult. The firm is working with mobile phone companies including Nokia and Motorola to test whether the G24i cells could charge handsets in rural Africa. For £6-£8, he says, the company can supply a flexible strip of solar cells that can produce 0.4 to 0.5W of power. It’s a relatively meagre output, but more than enough for at least 10 minutes of phone calls a day. And that, says Betzel, can make a big difference. “Over two billion people live without access to energy. This isn’t about providing expensive, Rolls Royce- quality solutions. It’s about improving their quality of life.” Similar solar chargers made of silicon cost about £30.

Affordable Zero Carbon Homes…

The Cooperative Bank has teamed up with Living Space 21 to provide a new green solution to housing.  From the press release (7th August):

Co-operative Bank sponsors ground breaking green housing initiative

Tackling climate change and providing affordable housing for first time buyers are the biggest challenges facing the British housing market today. With this is mind; the Cooperative Bank has teamed up with Living Space 21, a new housing developer, to offer homes that are not only eco-friendly but, also within reach of those starting out on the property ladder.

This exciting new partnership directly addresses the Government’s promise to increase the UK’s house-building programme by 20%, which would provide an additional 3 million homes by 2020. Furthermore, with the Housing Green Paper 2007 setting targets to reduce property carbon emissions by 25% by 2010, these new homes, which have inbuilt eco features will be well placed to help meet this objective.

The eco benefits of these homes include timber frames, sourced from sustainable forests, rain water capture and recycling, plus sloped roofs which maximise solar efficiency. However, these features do not in any way comprise the quality or design of the build. The contemporary apartments have been designed by Living Space 21 and their pioneering building techniques enable them to be tailored to almost any location, leaving the lightest environmental footprint possible for the price.
