Carbon Zero Builders Wanted – 2

Just announced through Building – Galliford Try and Affinity Sutton Group housing association have been selected by English Partnerships to jointly pioneer one of the first major carbon neutral developments in the UK. named as the preferred bidder on the planned redevelopment of the former Graylingwell hospital site in Chichester, Sussex, creating 800 carbon neutral homes.

See previous post on isite here

An interesting project to watch to see how much of the carbon reduction to neutral is achieved through offsetting and that achieved through real action in design, construction and technology

Conservatives, Blackpool and the built environment

Attending a number of fringe events hosted by Climate Clinic at the conservative conference in Blackpool (because of the location not any political alliance) looking for hints as to the future treatment of the built environment left me slightly worried. Cutting through the rhetoric, I found very little conviction that politicians or advisors have a handle on dealing with our sector. There appears to be a blinkered approach with no joined up thinking.

Key themes I took away include

More political focus will be placed on the built environment sector as a tool to reduce overall carbon emissions. However this would seem to lead to more confusion as Merton Rules, Building Regulations, grants and subsides, etc get tampered with.

Mircopower, decentralised power suppliers and feed in tariffs are very popular. Interesting question though is how large scale green power schemes – such as wind and Severn barrier become environmental problems associated with centralised power

The Quality of Life group group paper Blueprint for a Green Economy from authors Goldsmith and Gummer is the mantra of the conservatives, with praise upon praise being heaped on to Zac Goldsmith every time the document was mentioned. Yet, this is a market driven approach, very close to Tory values that may well have contributed to where we are today, (for example ‘Construction companies must take the lead in ensuring new buildings are as green as possible,) and has a few striking omissions, such as biodiversity. Still worth reading …just in case. The highlights relating to buildings include:

  • Stamp duty should be abolished on homes which have a very low carbon footprint.
  • Local authorities would have the power to reduce council tax bills on low-carbon properties, and homes which reused water efficiently, as incentives to occupants to be greener.
  • Public buildings should be forced to adopt the highest possible energy performance standards.
  • There should be greater incentives to construct eco-friendly homes.
  • Construction companies must take the lead in ensuring new buildings are as green as possible, and to prioritise the environment when considering ways to revamp existing buildings.
  • Home Information Packs (Hips) should be abolished by any incoming Conservative government and replaced with National Building Standards, which would ensure all properties reached required standards.
  • Walking, cycling and using public transport should be prioritised as part of the planning process for any new neighbourhoods. (source BBC)

Two non political comments I took away, which sums up the problems we face:

From Michael McCarthy, Environmental Editor of the Independent“be clear: this is the ultimate political issue”

and from Sunand Prasad, President of the RIBA, who queried in the Quality of Life question time session whether this issue was too big to be political and requires some form of non, or a – political body to drive, to collect green taxes and make the ‘polluter pay’.

Listening and reading between the lines, and indeed one of the questions at the Quality of Life question time,was the difference between he Goldsmith-Gummer approach and those who feel the environment agenda has gone to far, notably the Redwood degulation camp.  The question to the panel was for how long can both remain within a conservative party.

Leaving the event the most striking moment however was the fantastic sunset, in contrast to the high energy usage Blackpool Illuminations, just a reminder that the earth and nature is far superior and will out survive our messing it up, and how important nature and biodiversity etc are in the balance of our approaches. (Ok, a Gaia moment but hey…)

End of back to backs

Pleased to note the greenhouse project in Beeston Leeds as reported in Building today. (Work starts on UK’s first carbon negative project) Having had an office on the fringe of Beeston for about 10 years, it was an area that fascinated me, a built environment from another era, with most of the housing of 19th century stock, including what must be some of the last remaining small back-to-back terraces

The greenhouse project is billed as being carbon negative – rather than just carbon neutral. It is hoped this includes the construction processes as well as the use of the new homes, and NOT achieved through carbon offsetting but through real improvements in process, management and technology.  I searched for a definition of carbon negative – but unable to find anything useful that was not linked to carbon off-putting, but for an excellent overview see this Worldchanging link 

It is fascinating to see how far we have come from back to back housing

 The rows of houses were literally built ‘back to back’ one room deep.   The typical back to back house has three rooms, one above the other. The housing became renowned for squalor, disease and poverty due to its cramped design and poor sanitation.

“Our house is a three storey terrace with a common yard, a privy and wash house which we share with fifteen other families.”

New housing to fund energy improvements to old stock through 106?

Interesting post on today’s Building website – exploring the use of Section 106 on new developments to improve existing housing stock in the area

Carbon Accounting for the Construction Industry

Noticed this (free) Envirowise event in Loughborough on 30th Oct.   Delighted to see David Hampton (Carbon Coach) is one of the speakers. I plan to attend and report back through here, and hopefully track down that elusive Construction Carbon Calculator.

For Lancashire Best Practice Club members – this is the type of event we need to host here in Lancs.  I will investigate.

How much coal is required…

…. to run a 100-watt light bulb 24 hours a day for a year?

Came across the useful – and frightening – link on How Stuff Works.  Take a look – the answer is a lot and a lot of carbon emissions as a by product.

Timely as news from the government to phase out traditional light bulbs.  But why wait till 2012 –  they are already yesterdays news in Australia and elsewhere.

Greenpeace director John Sauven, reported in the Guardian, said: “For every year of delay in getting rid of these bulbs, 5m tonnes of CO2 are emitted into the atmosphere unnecessarily.”

Want to stop global warming? – New York Times

I have mentioned the Architecture 2030 programme here before. (An American programme to reduce carbon levels in construction and use of ALL buildings by 2030, 5 years ahead of the predicted point of irreversible damage when carbon emissions are predicted to hit 450ppm – they are currently at 380 something.)

Architecture 2030 is very focused on removing existing and halting planned coal power plants in the states ( and elsewhere) as the single biggest contribution we can make.

Today they placed a full page ad in the New York Times. Although obviously focusing on the states the ad carries some strong messages for the built environment generally.

Have we, here in the UK , stopped to think of the relationship between coal power stations, our built environment, and the use of energy within buildings that continues to ‘justify’ the continuation of these power stations to generate electricity. Just think of our typical night time cityscapes – illumination from empty buildings, lighting and other unnecessary illuminations, nearly all pulling power from coal power stations, and thereby needlessly increasing carbon emissions.

According to the BAA Campaign for dark skies – the amount of additional carbon dioxide pumped into the atmosphere due to inefficient UK street-lights in the last 12 month is 540,271 tonnes. (That’s the British Astronomical Association . not the other BAA). (and that’s just street lights?)

Asbestos in system buildings

Noted on the HSE website…

This Sector Information Minute provides inspectors with background information on the issue of potential asbestos fibre release in CLASP and other ‘system’ buildings built between 1945 and 1980.

Measuring carbon savings in existing buildings

It has long been recognised within the blogosphere at least that the biggest contribution the built environment can make to national and global carbon reductions is through existing building stock, not only through the drive for zero carbon homes by 2016 for example.

And in case we need reminding why existing buildings are key, Cyril Sweett estimate that by 2050, 60% of UK buildings will still predate 2006 Building Regs, with corresponding high fuel consumption and carbon emissions. Barring a massive technological improvement in electricity generation at source, our only option is to address existing stock. (Elemental)

Today is the start of the CIBSE 100 days of carbon clean up.

It is good to see programmes like this that address the existing building stock. Signing up to this programme will give you the guidance and tools to reduce energy and carbons within your buildings, including TM22 – the CIBSE guide to measuring carbon savings. For example are you aware of the following carbon emission factors?

  • Natural Gas: 0.194kg CO2/kWh
  • LPG: 0.235kg CO2/kWh
  • Oil: 0.265kg CO2/kWh
  • Biomass: 0.025kg CO2/kWh
  • Electricity: 0.422kg CO2/kWh

Bit of a difference there between electricity and biomass!
Check out the CIBSE programme and make a saving and contribution today.

Making refurbishment a green opportunity

In addition CIBSE are hosting the Great Refurbishment Event

or refurbishment of commercial buildings both on client or consultancy side, then the Great Refurbishment Event held at The Royal Society, London on the 24 October 2007 is a must attend event for you. Experts throughout the building services world will share with you their strategies and techniques to take you from the planning stage through to integrating your refurbishment into improving your energy performance.

carbon offsetting ignorance?

A recent Guardian article revealed a survey showing that

Some 55% of survey respondents had either never heard of carbon offsetting, or had heard the name but didn’t know anything about it. When asked which term best described carbon offsetting, 66% were unable to give an accurate definition.

One in five said it was “the release of carbon dioxide into the atmosphere” while 19% selected “a chemical process which neutralises carbon dioxide gas before it is released into the atmosphere”. Some 2% of respondents thought carbon offsetting was a “new technique that eases trapped wind caused by carbonated/fizzy drinks”.

it may be good news though that:

Only 1% of Britons told researchers they had ever paid into a carbon offsetting programme.

With more and more use of carbon off putting schemes being used in the built environment to archive zero carbon status, one wonders what the level of understanding really is. (Maybe a survey in Building, Phil)
