Counting construction carbons with ConstructCO2

This blog has reported on numerous occasions (eg here and here) on the need to measure and improve carbon emissions from construction activities separately from that of the building itself or the facility in use. And the need for an easy, simple to use tool.

As noted many of the available applications for calculating carbons were linked dubiously to carbon offsetting schemes.  Of note for use in construction were the Google Carbon tool (but not construction specific enough) and the Environment Agency tool (but is proving to be too detailed and cumbersome for most projects)

Measuring and improving carbons on site is increasingly important as more and more projects seek higher standards to BREEAM and Code for Sustainable Homes (and soon Non Dom Buildings).  One recent project set ‘damages’ for the contractor not achieving the ‘management points’ (for waste, CO2 and considerate constructor standard) for CSH at £40k per point. (See the CSH Technical Manual for more on this)

Recently at EcoBuild Paul Morrell, Construction Tsar commented  that focus on carbon emissions should be a number one site priority as it is measurable and addresses other areas of ‘waste’ in the industry

And yet the majority of contracts just do not know their project carbon footprint, whether its close to 1tonne or over 100tonne. We do not have a feel for the magnitude of emissions, or indeed what 1kg of CO2 actually looks like.

So it is good news to see the release of ConstructCO2, developed through Evolution-ip, by construction people for construction use.

ConstructCO2 is a simple carbon calculator based on the premise of keeping it simple and easy to use on site. It makes use of existing site approaches for data collection (induction sheets, daily log-ins, plant sheets, utility invoices etc). Carbon emissions through transport are calculated through use of google mapping API .

Construction (people) travel miles are recorded for management, operatives and visitors. (With a dispersed project management team you will be surprised at the carbon footprint of a project site meeting and probably think of alternative arrangements) Material transport miles are derived from delivery notes or goods received sheets.

Where the power of ConstructCO2 lies however is in its reporting. Construction carbons can be measured in terms of co2/£project value, co2/dwelling, c02/m2, co2/bed or other, enabling benchmarking with other projects and generically through KPI’s such as those from Construction Excellence.

But simply knowing the project footprint, the construction company’s total project footprint, and where the biggest areas for carbon emission are enables action for real improvement.

ConstructCO2 is currently being used by a number of different projects in what I guess would be called a beta stage. Current projects include a large new build hotel project, a small industrial refurb project, school extension and an architect’s office.

Currently the use of ConstructCO2 as a tool is free, with a (currently optional) fee based support and training package to help contractors understand carbon issues, carbon standards requirements, measuring, benchmarking and improving carbon footprints.  So it makes sense to take the opportunity now, measure and understand the carbon footprint of one of your projects. At the moment sign up is through request via email contacts on the ConstructCO2 front page

Future developments include the option for live energy feeds from site power meters to ConstructCO2 and live exporting from ConstructCO2 to Google and Pachube for example.

ConstructCO2 is on twitter at @constructco2 and has a ning forum in development for discussion and benchmarking of project carbon issues.

CBI low-carbon economy roadmap to 2020

For the first time the UK’s leading business group has set out its vision for a low-carbon economy in a series of climate change roadmaps.  The roadmaps, called ‘Going the Distance’, set out a timetable of action to ensure carbon emissions targets are met, and the measures that will be needed to put the UK in pole position in the development of low-carbon technologies.

Comment: the roadmap could appear to be protecting industry (only a 6% reduction) and focuses heavily on nuclear and carbon capture (but not until 2013), sees the Severn Barrage as the way forward and wants a government led, rather than industry led  initiative.  (what happened to market led economies?)

CBI are proposing the following contributions per sector from 2006 

Industry 6%

Buildings 43%

Transport 29%

Energy 39%

(not sure how much the roadmap avoids double counting, particularly with energy reductions) 

 

In the buildings roadmap the CBI wants to see:
• Smart meters fitted in homes and businesses so users can see how much power they are using.
• Incentives to encourage consumers to buy more efficient washing machines, fridges and freezers.
• Loft insulation installed in three million homes.
• Agreement on a realistic definition of ‘zero-carbon’ for new homes and business premises.

  Download: Going the distance: the low-carbon buildings roadmap 

Forty percent of the UK’s carbon emissions come from energy consumed in buildings.1 To meet the UK’s 2020 CO₂ target, the CBI believes carbon savings of 43MtCO₂ should come from buildings, equivalent to a 20%reduction from 2006 levels.

Nearly two thirds of these savings can come from energy efficiency measures that will save money as well as carbon, while remaining savings will need to come from renewable and low carbon heat and micro-generation and zero-carbon new buildings. Progress made in decarbonising the UK’s electricity supply will also drive emissions reduction

zero carbon definition

Climate Change and Sustainable Development Team at the Department for Communities and Local Government have launched the consultation on the definition of zero carbon homes and non-domestic buildings.

see the press notice at http://www.communities.gov.uk/news/corporate/1101131.

They are interested in views on the definition of zero carbon homes and non-domestic buildings – consultation closes on Wednesday 18 March 2009.

You will see from the press notice that the Zero Carbon Hub will be organising workshops in February.  For more information about the workshops, please contact the Hub at info@zerocarbonhub.org.

code for sustainable buildings

A while ago  I posted on the UKGBC task force UKGBC task group too important to be so narrow? and how it should embrace an open collaborative wiki style approach to the development of the Code for Sustainable Buildings.
This code will be so influential and far reaching that it cannot be developed behind closed doors, behind closed servers etc

Now the good news is that the UKGBC have started a consultation on the development of the Code.

Closing date back to the UKGBC is on the 12 December. A very short window compared to the months given to the same process for the Construction Sustainability Strategy.

The document can be downloaded from here, and a discussion area has been set up on the be2camp forum.

sustainability and the crunch

The UKGBC released results of a survey earlier this week, which should be seen as important reminder that sustainability is here to stay despite the economic situation.

Results released today from a poll held during a webinar hosted by the UK Green Building Council have revealed that British companies see sustainability as a growth area over the next 3 years, despite the current financial crisis. More than 92% of respondents felt that sustainability would either grow as an issue or stay at the same level despite the credit crunch.

27% said that the financial crisis has had no adverse effect on their organisation’s efforts to tackle sustainability and more than half (55.54%) said it had caused it to become an even bigger focus for them over the past 6 months.

The general consensus from respondents was that during these times of uncertainty, it is important for government to stick to ambitious green targets, maintaining the direction of travel for policy and regulation. More than 96% either agreed or strongly agreed with this statement.

This was supported recently via colleague Pam Broviak, who recently sent live tweets and comments (via Twitter) from the US GreenBuild08 conference:

Me: whats the buzz re green v credit crunch ?

Pam:  everyone says it really hasn’t affected it a lot

Of course if we consider the triple bottom line, of environmental, social AND economic sustainability this makes sense. But as has been commented here before the survivors of this financial crisis will be those who have resilient practices and approaches in place – and that this must include social and environmental

government to focus on 50% construction waste reduction

Waste and recycling minister Jane Kennedy has revealed that tackling business waste is to be a “top priority”

as reported on www.letsrecycle.com

Ms Kennedy explained that the Government would now develop proposals aimed at supporting businesses to look at ways they could reduce, reuse and recycle their waste, with a particular focus falling on small businesses. She added that the government hoped to offer support in light of Envirowise research which claimed businesses spend 4% of their annual turnover on waste disposal.

One area that the minister said that she hoped to make some real headway with regards to waste reduction and recycling was the construction and demolition sectors, with Ms Kennedy keen to build on targets to halve the amount of waste generated in these sectors by 2012.

Identifying work already done in this area, the minister said she believed the 2007 Waste Strategy for England had “rightly identified” construction and demolition waste as in need of action, leading to the Sustainable Construction Strategy launched in June and the legal requirement for each business to have a Site Waste Management Plans, which the minister believed would play a part in keeping focus on waste at this time of economic instability.

——

All good news, but reliance on Site Waste Management Plans to acheive 50% reduction in waste is not the way forward and more empahsis should be on eliminating waste, not simply finding better ways to mange waste after it has been created.

In addition one of the biggest moans from site contractors I hear at the moment, across the country, is the lack of real engagement from clients in driving Site Waste Management Plans

And as to spending 4% of their annual turnover on waste disposal this seems very low for the built environment sector when the real cost of skips is estimated at £1500, not the £100 costed for, and the estimated waste in the sector is at 30%, and DEFRA suggesting that one third of solid materials delivered to a project is wasted.
