Construction Carbon Calculator – a challenge?

By far the highest number of searches that end up at this blog are related to the words Construction Carbon Calculator, and pages in this blog that talk about carbon calculators receive the highest visits.

This leads me to think that there is not a suitable carbon calculator for our industry – for the construction process – not the building or facility

A challenge then – is anyone out there aware of or using a calculator, or is anyone developing one.?

It could well be that we just do not know what the carbon footprints of construction activities really are, and that is worrying.

Comments, views and links to those construction carbon calculators please…

Offsite2007

I have a meeting planned down at the BRE in a week or so and hope, as part of the visit to view the buildings erected as part of the Offsite 2007 event. (now closed, but the website contains much useful information)
As we lead up to the LCBPC Innovation event on the 5th July, its well worth looking at the modern methods of construction innovations from offsite 2007, both in off site  prefabrication, in innovative on site technology, and near-carbon-zero construction.  The photo diary blog  of the construction and event provides an fascinating insight.

Of particular interest is the Rethink School building from Wilmot Dixon – The school building itself is a teaching and learning tool, with every part of the school’s design, construction and operation an educational opportunity.

Slow Home Futures

In comparison to the news that the UK housing sector is to be invetsigated, and with the media quick to pick up on the numbers that only 3 in 4 (76%) of people buying new homes are satisfied with quality, I was intrigued to get news from the USA on the emerging Slow Homes Movement.

This movement is similar to the slow food movement that kicks back against the fast food industry, kicking back as it does against the fast home industry – as the worldchanging website states:

Brown (founder of SHM) makes the increasingly known correlation between suburban living and obesity, indicating that fast food and fast housing not only have comparable results within their respective industries, but literally the same result: a declining state of health across a huge swathe of the North American population.

The movement is based on an interesting, worthwhile and common sense set of 10 principles – which may ring a few bells in our own hosuing sustainability / carbon zero agendas – or maybe not :-

1. GO INDEPENDENT Avoid homes by big developers and large production builders. They are designed for profit not people. Work with independent designers and building contractors instead.

2. GO LOCAL Avoid home finishing products from big box retailers. The standardized solutions they provide cannot fit the unique conditions of your home. Use local retailers, craftspeople, and manufacturers to get a locally appropriate response and support your community.

3. GO GREEN Stop the conversion of nature into sprawl. Don’t buy in a new suburb. The environmental cost can no longer be justified. Re-invest in existing communities and use sustainable materials and technologies to reduce your environmental footprint.

4. GO NEAR  Reduce your commute. Driving is a waste of time and the new roads and services required to support low density development is a big contributor to climate change. Live close to where you work and play.

5. GO SMALL Avoid the real estate game of bigger is always better. A properly designed smaller home can feel larger AND work better than a poorly designed big one. Spend your money on quality instead of quantity.

6. GO OPEN Stop living in houses filled with little rooms. They are dark, inefficient, and don’t fit the complexity of our daily lives. Live in a flexible and adaptive open plan living space with great light and a connection to outdoors.

7. GO SIMPLE Don’t buy a home that has space you won’t use and things you don’t need. Good design can reduce the clutter and confusion in your life. Create a home that fits the way you really want to live.

8. GO MODERN Avoid fake materials and the re-creation of false historical styles. They are like advertising images and have little real depth. Create a home in which character comes from the quality of space, natural light and the careful use of good, sustainable materials.

9. GO HEALTHY Avoid living in a public health concern. Houses built with cheap materials off gas noxious chemicals. Suburbs promote obesity because driving is the only option. Use natural, healthy home materials and building techniques. Live where you can walk to shop, school and work.

10. GO FOR IT Stop procrastinating. The most important, and difficult, step in the slow home process is the first one that you take. Get informed and then get involved with your home. Every change, no matter how small, is important.

Low-Carbon Building Accelerator

Noticed this on the Carbon Trust website recently:

The Low-Carbon Building Accelerator seeks to demonstrate that major refurbishments of non-residential buildings can be completed in both a low-carbon and a cost-effective manner. It involves the Carbon Trust’s specialist consultants working with a range of building projects in the retail, hospitality, government and education sectors. The specialist consultants are working with developers and their advisors, providing input on how to ensure that refurbishment projects are carried out in a way that minimises the carbon emissions from the building. Case studies backed up by robust data will be published at the end of each project

 It will be interesting to review the case studies on this one, but it is significant the Carbon Trust has identified building as one of …

…those technologies that offer the greatest UK carbon saving potential in the short to medium term and also where the Carbon Trust investments can be material in bringing forward these technologies.

Dr David Vincent, Technology Director of the Carbon Trust, explains, “The assessment enables the Carbon Trust to focus its resources effectively. By targeting those technologies which offer high carbon savings potential and where our resources can be material, we can take the lead on low carbon technologies innovation in the UK.”

 

 

Schools rebuild project ‘ignores green initiative’

The Sunday Times yesterday reported that the BSF programme is missing a big opportunity to promote sustainable building methods.

A report from the education and skills select committee, headed by Labour MP Barry Sheerman, will slam the programme for missing a big opportunity to promote sustainable building methods.

About £150m has been set aside to improve environmental standards on the Building Schools for the Future (BSF) scheme, but MPs believe this is a drop in the ocean in the context of the £45 billion BSF programme.

The Sustainable Development Commission told the MPs that it would add 15% to 20% to the cost of building schools to make them carbon neutral and more energy efficient. Schools account for about 15% of the public sector’s carbon footprint in the UK.

One committee source said: “There is no doubt the green stuff has just been tacked on as an afterthought in this programme � which is amazing given the government preaching about its green agenda.”

It would be interesting to hear comments from BSF programmes in the area….

Net Waste Method

As reported on today’s Contract Journal website, WRAP has published plans for a new standard to measure waste neutrality.  Further details and a pdf brochure can be downloaded from the WRAP web site Net Waste Method page.

In simple terms, WRAP considers ‘waste neutral’ to be where the value of construction materials wasted is matched by the value of additional reused and recycled content employed on a project. Adoption of this approach promotes consideration of all aspects of materials efficiency: reducing waste, recycling waste that does arise and using materials with recycled content. This is to be achieved with a reduction in overall environmental impact. By focusing on the commercial as well as the environmental costs of waste, it should deliver real benefits for the construction sector.

In particular, it highlights where companies can reduce costs and increase profits through greater efficiency. It also supports the demonstration of Corporate Social Responsibility.

Don Ward, chief executive at Constructing Excellence reported in Contract Journal said:

“We hope that contractors will look carefully at the real opportunity that the Net Waste Method can unlock in terms of improved profitability and reducing the impact on the environment.”

Comment:  But are we still missing the point here – real effort need to be applied upstream in the construction process, in the design, specification, procurement and planning stages to eliminate waste in the first place.  With recent reports from Defra that 1/3 of all solid materials  going to a site are not used on the project, and the UK Green Building Council that construction accounts for 20%  of all waste, we really need to focus on the first stage of the waste planning – elimination, then the other stages of Reduce, Reuse, Recycle and Dispose are not as much an issue, and reduction in costs along with increased profits will be easier to achieve.  Take a look at the pre-construction sections of the WRAP construction web pages

The WRAP website contains a wealth of information and should be on all construction / facilities management managers bookmark or favourite lists. (there is a section on Asset Management – within the construction section !)

It is possible to sign up for a construction wrap newsletter, but unfortunately I cannot see any RSS feed on the site, even for the news items

Rubble Trouble

The following was noticed from UK Green Building Council

50%
Percentage of UK greenhouse gas emissions from running buildings…

30%
…of those emissions could be cut by cheap and simple measures

10%
Percentage of UK emissions coming from producing building materials…

20% …of those materials on every new building ends up in a skip…

88
…producing in a year enough waste to build 88 Great Pyramids of Giza.

Hence the need for the Lancashire Best Practice Club Innovation Event on 5th July ( have you reserved your place yet?)

The inconvenient truth about the carbon offset industry

The Guardian on Saturday carried the concluding part of a major investigation, by Nick Davies showing how greenhouse gas credits do little or nothing to combat global warming. It is worrying how the offsetting industry has grown in this manner. Carbon offsetting has been referred to here and others as chocolate teapots, not at all addressing the carbon reduction. It has also been called carbon off-putting.

There is a growing trend in construction and property to address the required carbon reduction targets through offputting. This was illustrated within the recently published to internet construction (new housing) local plan from a local authority (down south!) which claims, and I guess this is typical:

Although carbon neutrality is possible by just using on-site measures, it is recognized that at least for the foreseeable future, it is challenging and expensive and therefore carbon offset is proposed as an alternative more cost effective option. On-site measures will be encouraged where possible to reduce carbon dioxide emissions, which will of course reduce the carbon offset payment.

(ie likely to result in a do nothing business as usual approach)

A one-off contribution will be required to the carbon offset fund, at a rate of £200 (index-linked)  for each tonne carbon dioxide by means of a Section 106 agreement or unilateral undertaking. Coupled with existing best practice in energy efficiency, carbon offset could provide carbon neutrality for a few hundred pounds per house.

(so .. for a few hundred pounds? – no problem then ?)

However – if as the Guardian article suggests that even ‘immediate‘ carbon offputting schemes may take 100 years to ‘offset’ -will we miss the window of time to act that scientists say we must address, (the reason for the urgency in all this carbon management) and of course miss the targets for zero carbon housing in 2016.

“I don’t think we’re going to make it…”

Dave over at the Carbon Coach brought my attention to an emotional shock response  video from TED.  Whilst you may not agree with all in the video, Venture Capitalist, John Doerr’s lucid presentation is indeed worth watching, it includes amongst other issues a view on what WalMart are planning for their stores globally, and the huge investments being made green innovation.

Comments I like from the video include  “There is a time when panic is the appropriate response!”
