eco towns or eco slums?

Lengthy and informative article by Charlotte Hunt-Grubbe on the Sunday Times website provides a good overview of the background, current status and future of the eco town initaive.

Starting with a dream:

Across the fair face of Albion, to the ringing of bells and the soft murmur of doves, appears a leafy flush of eco-towns. They are sun-dappled utopias, urban dreamworlds in which no human need is unfulfilled. Wildlife romps through bird-loud glades. People work at home or in business parks to which they can stroll or cycle. Public transport is swift, efficient and free, so cars are not needed. Community sports hubs, leisure and cultural facilities are so abundant that nobody wants to leave the town anyway. Children walk safely to schools in which the most popular subject is environmentalism. There are superstores for convenience, and farmers’ markets for friends of the planet. Allotments, too, for those who want to grow their own. Energy is renewable, insulation total and the carbon footprint zero.

Or a perception of what eco towns will be:

Sir Simon Milton, chair of the Local Government Association, spelt it out: “It’s no use building carbon-neutral, environmentally friendly houses if they are in the middle of nowhere with no facilities, so that people have to drive miles to buy a loaf of bread or take their kids to school.” If there were no local jobs or training, he said, the emphasis on social housing would serve only to create “eco-slums”.

and a comparison to overseas eco towns:

If only the UK’s new rash of eco-towns was as exciting as the high-profile eco-cities being planned abroad by British designers. “In Masdar,” says Lord Foster, “the pedestrian is king.” Masdar, the distinguished British architect’s scheme for a site near Abu Dhabi, will be a pioneering zero-carbon, zero-waste city. At first sight, its narrow streets, palm-tree-lined walkways, mosaic floors, low-rise buildings and sunlit open spaces are redolent of a modern Middle Eastern city. But there’s something profoundly otherworldly about Masdar. Sky rails meander overhead, solar-panelled awnings shade the streets, and there are no cars above ground. “We’re designing a new kind of transportation system,” explains Foster, “with driverless electric vehicles below street level that you can operate using your mobile phone.” When you dial them up, they take you straight to your destination.

eco … build, homes, villages and towns – pah… greenwash?

on zero carbon and routes to get there …

There have been some very worthwhile and considered articles and comments on the definition of and feasibility of zero carbon recently – take a look at Mels post .. and Phils post for excellent round ups and for good technical comment take a look at CarbonLimited from Casey

The difference in opinions and views is healthy – maybe there is no ‘one’ definition, maybe we should not waste (mental) energy on defining – but as per the zero accidents, zero waste and zero defects debates of recent years accept it as a worthwhile, Utopian goal and work how how to best get there. I recall from my TQM days the concept of zero waste drives lean management approaches, but absolute zero waste is not ‘defined’ – it is a philosophy.

From the supply, contractors, perspective the very confusing debate on what is zero carbon just encourages the ‘keep heads down until it blows over approach’. Understandable, but a strategy that will return to haunt those not prepared to address the changes we will have to make. Most do not have a strategy or vision for moving to a low carbon future, content to be led by circumstances.

Within the Route to Zero programme I run, we start to understand, from industry intelligence, what an organisations customers, shareholders, people and even suppliers are expecting in the context of zero carbon over the next 10 – 20 years. From this intellenge we can develop a maturity matrix of strategies and objectives that would be necessary, ie a Route to Zero. A matrix that would be reviewed regulaly as ‘requirements’ will unfold and change and most likely toughen up. Armed with such a route-map, organisations may not achieve zero , but have the evidence that they are thinking of a zero future.

And as to the general public, those who will buy the zero carbon homes, Mel is correct in pointing out the confusion we as an industry may be giving, a damaging message maybe? What home owners would like to know is the balance between capital purchase and the running costs per month, and what savings per month would a code 6 or zero carbon home give me over a traditional home? Take a look at the house sale literature in the states – this is exactly what green homes are sold on – a reduction in energy bills, making the purchase of green homes desirable, a no brainer and making non green homes nearly unsaleable.

Ad then there is the existing housing stock issue …. which is where effort must be put, not on new build, eco challenges, eco home etc etc ….

egan: four out of ten for effort

As reported on Building today, Sir John Egan Author of Rethinking Construction speaking at a reception at the House of Commons to mark 10 years since the publication of his report said he would rate the construction industry’s performance since as “four out of 10”.

Egan particularly criticised housebuilders for failing to follow the guidelines laid down in his report. “[Housebuilders] have made no cost improvements at all. Absolutely nothing. Also, their productivity processes actually generated much less than half of the demonstration projects.”

“I just don’t think they were trying. In this ‘nice decade’, as the Bank of England called it, they really didn’t try. And now they’ve got their comeuppance. It’s very, very sad.”

Egan said that housebuilders could have made progress with simple productivity and design improvements and more off-site building. “the houses could be costing a great deal less than they do, and there would still be a market.”

Egan went on to say that the government was partly to blame for “not trying” to be a good client in its construction projects.

Summing up the lasting impact of the report, Egan said: “We have to say we’ve got pretty patchy results. And certainly nowhere near the improvement we could have achieved, or that I expected to achieve.”

I would concur with Egan on this one, with some very successful exceptions, the principles and targets set by the Rethinking Construction report have not been understood or adopted let alone met. Many in the industry are not even aware of these targets. It continues to amaze me the lack of knowledge, in some cases of the existence, of the Egan report, across the industry and in education.

With a score of four, questions must surely be asked of the effectiveness of the organisations established, with government funds, to deliver Rethinking Construction.

eco towns and zero carbon – chalk and cheese?

What caught my eye browsing in coffee shop this evening:

on the zero carbon house

Barratt Developments has unveiled what it calls the first zero-carbon house developed by a volume housebuilder, built at the Buildings Research Establishment in Watford, packed with the latest technology, including solar panels, rainwater harvesting and an air source heat pump.

Its new kind of concrete walls and floors, combined with super insulation and triple-glazed windows, means its heat requirement will be minimal as it is airtight. Fresh air is brought into the building through a heat exchanger, which extracts the heat from outgoing stale air and puts it back into the house.

Mark Clare, chief executive of Barratt, said it would not be easy to reduce the cost of the prototype to commercial levels but he was confident it could be done. The important thing, he added, was to build houses that people would buy.

The public and builders still need to be convinced, according to the NHBC Foundation report, and it would seem todays kids – who will buy the homes – Kids dream homes – whose dream homes aren’t high on eco features.

The UK Green Building Council released a report this week defining what a zero-carbon house should be in practice. This is likely to form the basis of the legislation that the government is soon going to work on.

Housebuilders had been unhappy at the costs of going zero carbon and had wanted to be able to invest in off-site renewable energy such as wind turbines that would be cheaper for them. But the government is likely to endorse the GBC proposals that a zero-carbon house should produce almost all its energy on site or very near by in, say, a communal heat and power system.

Barratt plans rolling out its zero-carbon homes on the site of Hanham Hall hospital near Bristol. It will build 200 of them, a third of which will be affordable to lower-income buyers. All will be code level six and will completed in 2011, five years ahead of the deadline.

a guide to zero carbon homes

Zero carbon homes in 100 words.

The UK Green Building Council released a report this week defining what a zero-carbon house should be in practice. Download from here

Still to read in detail but on first read appears to be a welcomed, considered and helpful guide, with a time-line to help organisations on a route to zero.

There would however appear to be little focus on the construction process, the actual building of zero carbon homes, (an estimated 3-4 years or 11% of the total carbons in the homes life cycle). This is the one issue we desperately need to address, to get buy in from builders. Many of whom may look at this and conclude it has nothing to do with them – other than install or assemble different bits of eco kit and / or materials. For example, construction waste, construction site impacts and considerate contractors scheme – all part of the Code 6 requirements isnt mentioned within the guide. (Site waste management planning is mandatory)

Others, and I know fellow bloggers will, soon comment on the renewable energy and technology aspect of the guide… watch this space…

Finally (for now) I hope that this definition is the same in the soon to be released UK Construction Strategy for Sustainability !!

can data centers power all homes …

How green is your data center? Stumbled upon an amazing post and comments over at The It Sanctuary

According to figures from IT market research company Forrester Research, a data centre with 2,500 servers – relatively small compared to many out there – will devour enough electricity over the course of one month to power 420,000 homes for a year. *

That’s bad news for the environment – and it also takes its toll on a company’s bottom line. Analysts at IT market analyst firm Gartner calculate that energy expenditure typically accounts for about 10 per cent of the IT budget, and is likely to rise to as much as 50 per cent over the next few years, as energy prices continue to soar.

As the comments on the post hint at – how well is IT covered within an organisations ISO 14001 scope, impact and assessment exercises? Or even within their CSR, Corporate Social Responsibility remits? With something like 60% of a buildings / organisations energy requirement being IT related, it needs to be a central theme.

But its the ability of data center energy to power homes that needs urgent investigation. If these numbers are correct thats a staggeringly high, unbelievably high, number of homes and would resolve the domestic electricity demand at a stroke. I will check the research and invite Forrester Research to comment here,
