Green Schools

green school /grEn skül / n. a school building or facility that creates a healthy environment that is conducive to learning while saving energy, resources and money

To help educate and encourage construction firms and others about the benefits of sustainable schools the US Green Building Council have recently launched a site dedicated to Green Schools  According to the site, green schools, on average, save $100,000 a year, use 33% less energy, and reduce solid waste by 74%. They also increase learning potential, reduce teacher absenteeism and turnover, and provide opportunities for hands-on learning.

The site contains a number of resources, but listening to the 9min video of students talking about environmnetal stewardship as a result of their green building is very strong.  “the new building had no new smells – which is good because those smells are only chemicals” 

With criticism of the green aspects of our Building Schools for the Future it would be good to hear of similar ‘awareness‘ resources in the UK.

Webinar – Code for Sustainable Homes

Further to the last post on carbon neutral and Code for Sustainable Homes, I am reminded from Phil’s blog over at Sustainability Blog that Building are running an on line semiar– a webinar on Code for Sustainable Homes.

Register and details here. 

(Unfortunately I am running a real life event at UCLAN, otherwise I would be there, or here, in front of wood stove fire with laptop!)

Carbon neutral or zero – defined?

Another excellent report from the Centre for Integrated Sustainability Analysis, Carbon Sense and Sensibility offers a definition of carbon neutral by looking at 11 websites that offer carbon neutrality calculators and services (offsets).

The definition is based around the idea of concept of measuring a carbon footprint and then seeking to cancel out that footprints with some kind of equal but opposite behaviour or consequence.

A must read for any organisation considering offsets to achieve neutrality or any carbon offset

.. you need to ask questions about just what carbon you are responsible for, how it is being measured and then exactly where the carbon credits have come from, how reductions have been verified and how you will know that once you have paid for those reductions they are retired so that nobody else can buy them …

gulp…

This then is very different from zero carbon -where activities are not neutralised but reduced to zero through ‘improvement’ activities and just doing things differently, and certainly not through offsetting.   (and the Code for Sustainable Homes calls for Zero Carbon – not carbon neutral ?)

A zero energy building (ZEB) or net zero energy building is a general term applied to a building with a net energy consumption of zero over a typical year.In October 2007, The Uk Green Building Council warned that few zero carbon homes were actually being built as as the criteria for carbon neutral stamp relief was so stringent. However, although “It’s not a legal obligation that zero carbon homes are built now”, “building regulations are being increased in line with the Code for Sustainable Homes over the next nine years”

Unravelling carbon footprints in supply chains

We hear allot about supply chain management within our industry, and until recently mainly in the context of improving value, relationships, reducing costs, waste and all the nice performance improvement stuuf.

What if we add reducing the carbon or ecological footprint into the supply chain management debate.

An excellent paper from the Centre for Integrated Sustainability Analysis – Unravelling the Impacts of Supply Chains – A new Triple Bottom Line accounting approach looks at just this issue.

It also raises the fundamental question on calculating carbon footprints – we are concerned in the main, at the moment, with direct or primary emissions – ie those we, or an organisation are directly responsible for,  How about those (secondary) emissions upstream, through the supply chain activities, raw material production etc, which in the context of a construction footprint surely must be taken into account.
We have seen this exercise start and stop within other sectors. for example the large supermarket organisation – but will it only be a matter of time before a wider view on the construction carbon emissions and contribution is expected within the built environment?

Get Sus! promotion…

Melanie over at Get Sus is having currently holding a promotion drive to attract more subscribers to her excellent (and free!) Get Sus e-mail newsletter service that offers sustainable construction news for undergraduates, post-grads and professionals with an interest in sustainability and the built environment

It covers good practice case studies, new books and websites, sources of funding, and work experience, placements and permanent vacancies.

neutral, zero or offset?

With the proliferation of websites and services offering to calcuate your footprint and allow you to offset, it is good to come across one site that offers a very different approach to get the offset message across.

About CheatNeutral

Cheatneutral is about offsetting infidelity. We’re the only people doing it, and Cheatneutral is a joke.

Carbon offsetting is about paying for the right to carry on emitting carbon. The Carbon offset industry sold £60 million of offsets last year, and is rapidly growing. Carbon offsetting is also a joke.

It is also very encouraging to see that the people behind Cheat Neutral support, recommend and provide links to Contraction and Convergance.  Again from their site:

  • Learn about Contraction and Convergence. C&C is a framework for agreeing a global cap on carbon emissions. We believe that to make our individual sacrifices count, we need a global framework that caps the amount of carbon emitted, creates a timeframe for reducing emissions to a safe level, and distributes carbon credits equitably. C&C satisfies all of these, and would make carbon trading fair and effective. Good resources are at  www.gci.org.uk

RICS – eco-harmful claims?

Recent research and claims from the RICS that some energy measures recommended in EPC’s may take up to 208 years to recoup costs has been widely commented on – in Saturdays Telegraph,(solar heating saves energy, wastes money) in Building but with more astute comment from Phil at SustainabilityBlog and at CarbonLimited.

This approach obviously damaging to the homeowners motivation in improving existing housing stock, or indeed other environmental initiatives, and maybe another eco-harmful shot in the foot from the RICS
There is also the underlying debate about the method of calculation of energy savings, and indeed energy costs.  Following the debate through CarbonLimited and the Grist article that argues electricity costs are political and not economic

Coal – safe cigarettes for the built environment?

 

isite Friday comment:

Coal has certainly been in the news, in comment columns and across the blogosphere just lately, upsetting environmentalists, campaigners and activitists. Here is a round up of coal – built environment related news and comments:

The recently commenced open cast site Ffos-y-fran in South Wales has received a scathing comment from George Monbiot in his Guardian column. As Zero Champion pointed out on the SustainabilityBlog, at the coal face, the organisations behind this project, Miller Argent, appear to be acting at odds to their environmental and or CSR visions and claims:

“We are trying to deliver lower energy, greener buildings in the right locations,” says Argent on its carbon dating page. And Miller released a CSR report this Spring which stressed its attempts to reduce the environmental impacts of its projects. “Corporate social responsibility, whether in terms of staff development… sustainable development or environmental management is at the core of our thinking,” says Keith Miller, group chief executive, at the back of the report.

The Myrthyr project is hardly sustainable, and as Monbiot states in his column, damaging to the good work in reducing carbons elsewhere.

This means that the coal in Ffos-y-fran will be responsible for almost 30 million tonnes of CO2: equivalent to the annual sustainable emissions of 25 million people (sustainable emissions are the quantity the planet’s living systems can absorb).

So in other words 25 million people need to reduce their carbon footprint to a sustainable level to balance the effects of the one coal project. How, MillerArgent, is this sustainable development.? How is this in the context of the Brundtland definition going to help future generations?

Greenpeace brought the proposed new coal power station at Kingsnorth into the news by protesting at the site. The Greenpeace film Convenient Solution, receiving warm praise at political fringe events recently, demonstrates the harm of coal power, and the wasted heat from the production:

The single biggest use of fossil fuels in the UK isn’t for electricity or for transport, but for creating heat to warm our buildings and power our industrial processes. So any solution to climate change needs to contribute to heating, as well as to electricity generation.

Only a week or so ago the American Acrtitetcure 2030 group placed a full page advert in the New York Times warning against the impact coal fired power stations will have on environmnetal, sustainability and carbon reducing actions, making the connection between coal and the built environment:

Buildings use 76% of all the electrical energy produced at coal plants. Buildings are the single largest contributor to global warming, accounting for almost half (48%) of total annual US energy consumption and CO2 emissions.

Wal-Mart is investing a half billion dollars to reduce the energy consumption and CO2 emissions of their existing buildings by 20% over the next seven years. The CO2 emissions from only one medium-sized coal-fired power plant, in just one month of operation each year, would negate this entire effort.

Over in Australia, the increasingly influential Australian Institute – ‘Clean coal’ and other greenhouse myths paper, availble from the UK Government policy hub website, busts the myths of coal:

Myth: Coal can be part of the solution.Busted: In reality, coal is the main problem, and curtailing its use is essential. There is no such thing as ‘clean coal’ at present, and there is a chance there will never be. There is no such thing as ‘clean coal’ for climate change. The description is a marketing triumph for the coal industry, like ‘safe cigarettes’ for the tobacco industry.

As many seek to achieve carbon reduction to neutral or zero through carbon offsetting, it appears the coal industry is pining hopes on the concept of carbon capture and storage, or carbon sequestration. This gives enough confidence for npower, as reported in the Guardian “coal continues to be an important source of energy for the UK and whilst this is the case, we believe CO2 capture and storage offers significant potential.”

The balancing, myth busting response from Oz?

Myth:Carbon sequestration can be the centerpiece of policy.Busted: This technology is unproven and expensive. There are several demonstration projects under way, but there is no immediate prospect of commercialisation.

So why is this important to everyday life in the built environment?

Well, coal illustrates just how very complex sustainability and carbon issue is, being personal, local, regional, national and global. The built environment demands the greater proportion of power from coal fired power stations.

The cement industry manufacturing process depends on burning vast amounts of cheap coal and contributes 5% of all global emmissions (It also relies on the decomposition of limestone, a chemical change which frees carbon dioxide as a byproduct.) So as demand for cement grows, for sewers, schools and hospitals as well as for luxury hotels and car parks, so will greenhouse gas emissions. Cement plants and factories across the world are projected to churn out almost 5bn tonnes of carbon dioxide annually by 2050 – 20 times as much as the government has pledged the entire UK will produce by that time. And like aviation the expected rapid growth in cement production is at severe odds with calls to cut carbon emissions to tackle global warming. (source, Guardian today Cement Industry comes clean)

Real reductions (not off-set reductions) in the design, construction and use of buildings will greatly reduce this demand. (This is one of the more important reasons why off-setting is bad for the built environment)

Whilst the everyday efforts on sites, in design, during construction and in existing facilities to reduce carbon and ecological impacts are so very vital, so is the awareness of the inter connections between so many of the wider social political, industrial and technological activities.

And of course there is something about the built environments claims and sustainability policies being watched by the media, pressure groups and bloggers, and all the publicity that may generate. Increasingly there are calls for some kind of watch dog to verify green claims, along the lines of the advertising standards commission, preventing misleading greenwash (a term that is used to describe the actions of a company, government, or other organisation which advertises positive environmental practices while acting in the opposite way (wikipedia)). At least no giraffes have been harmed so far…

Greenhouse myths, folklore and lies

Phil, zero-champion over at Sustainability blog alerted me to a great paper from the Australian Institute – ‘Clean coal’ and other greenhouse myths – in no nonsense , tell it as it is speak, available as pdf from the UK policy hub site
from the intro:

there is no longer any doubt that rising concentrations of greenhouse gases are leading to dangerous change in the global climate. In Australia, public and political opinion finally shifted in late 2006, with record droughts and an early start to the bushfire season. The Stern Review in October 2006 and the Fourth Assessment Report of the Intergovernmental Panel on Climate Change in February 2007 reinforced fears about global warming.

The debate has now shifted to the best means of reducing greenhouse gas emissions, and to the need for adapting to the level of climate change that now appears inevitable. Not surprisingly, the confusion and deliberate misinformation which formerly surrounded the debate on climate change has now shifted to the debate on how to tackle it. If there is to be an effective response (and the odds do not look good at present) very large changes are required in the global economy, and especially the global energy system. There will be both winners and losers among industries and companies. The potential losers are fighting to retain their advantages and privileges. Others are positioning themselves to profit, in some cases from ineffective or even counterproductive ‘solutions’.

Part of the strategy of potential losers and winners is to influence the public debate through myths and half-truths. Governments and oppositions are also attracted to convenient half-truths to mask inaction or lack of effective policy. Even among the many who sincerely support a reduction in emissions, there is much confusion.

My favourite myth?… no 8….

Buying carbon offsets is the same as actually reducing emissions.
  In fact, buying offsets is too often just a smokescreen for large emitters who intend to operate on a ‘business as usual’ basis. A reduction in emissions requires a reduction in emissions, plain and simple.

Green buildings on a mass scale?

An interesting article over at worldchanging, looking at a progamme being piloted by USGBC (US Gren Building Council) to … allow large companies to design, build and certify a green prototype facility–and then replicate that design all over the country.

It’s ideal for large retail operators with buildings that are more or less the same from city to city–companies like Starbucks, Lowe’s and Best Buy, all of whom happen to be participating in the pilot program

said Brenda Mathison, Best Buy’s director of environmental affairs. “The reality is that 60 percent of all energy use in the United States comes from commercial buildings, and we decided to take action on that.”
