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

1 Reply

James Meikle’s article in yesterdays guardian paints a picture of growing concerns and gaps in the thinking behind the current push towards ‘eco‘ villages and towns.

As a flagship for the huge number of homes to be built and eco towns to be created, Northstowe, if the Guardian report is correct has problems:

As the town takes shape, en route to at least a 20% – and hopefully higher – supply of renewable energy, combined heat and power plants could prove more efficient and cost effective than solar gadgets and micro generation on separate houses.

Sounds great, but the debate is our on micro generation – but only 20% renewable? !!!

More recently, Cooper decided that Northstowe must not be delayed by having to meet zero-carbon standards subsequently imposed for all new houses from 2016.

Ah ha – explains the 20% but if we can do it as an eco-challenge at Hanham Hall in Bristol – why not here?

James too makes the point on the level expected on the homes:

To start with, … private homes will only be at level 3 on the code for sustainable homes, producing 25% lower emissions than legally required so far, but no more revolutionary than homes already being built on some smaller developments. The requirement for affordable homes will be slightly higher at code level 4 – a 44% improvement on minimum standards, but again not as tough as might have been expected, given the experimentation already under way elsewhere.

In my opinion this is not flagship or even eco…

David Bard, a senior councillor on South Cambridgeshire council, which, with the county council, will consider the Northstowe plans in the next few months, says: ” I am not sure that anyone actually knows what is meant by an ‘ecotown’, let alone a ‘prototype ecotown’.

Time to rethink? Time to get back to basics?

Time to recall where Eco comes from – as it is a prefix used in most ‘sustainable ‘ iniatives at the present. Eco-this eco-that and eco-other is indeed the zetigeist of the moment. Eco is of course an abreviation of ecological – and as a prefix used to describe things realted to ecological issues. Except it isnt today, at least in its use for eco homes and villages etc.

Eco villages stem back to 1960’s community living, alternative technologies, living off grid with alternative lifestyles. Are todays eco villages just a clever greenwashing of of that ideal? (A greenwash that probably covers all 6 of the greenwash sins!)

Where is the community, social enterprise, regeneration, ecological diversity protection thinking in these developments?

It would be very interesting to see calculations for the ecological footprint of eco-developments such as Hanham Hall and Northstowe and how they would compare to other or non eco developments. There is much focus on carbon footprints, understandably as its tangible and easy to understand – but if we use the prefix eco – lets focus on the ecological footprint as well.

I have posted on the LEED ND (neighbourhood development) scheme here a few times – it would be fascinating to assess Hanham Hall or Northstowe against this standard. Just looking at the evidence required for submission for this standard would (hopefully) cause a rethink, or dropping of the prefix Eco ! for example:

  • Smart Location and Linkage, (smart location means ecological consideration!)
  • Neighborhood Pattern and Design,
  • Green Construction and Technology and
  • Innovative Design

Any BREEAM assessors, any LEED ND assessors out there looking for a challenge? Anyone out there willing to fund a project to ‘test’ the claims being made? These projects underway now will shape our future housing construction, living, and social well being.

Why do I hear the Pete Seger song when I think of eco-towns

Little boxes on the hill side, little boxes made of ticky-tacky.
Little boxes, little boxes, little boxes all the same.
There’s a green one and a pink one and a blue one and a yellow one,
… more

So time for a rethink and real innovation – as Henry Ford famously said “If I asked people what they really wanted they would have asked for faster horses” Will we still get little boxes ?

And quietly the transition-towns movement gains pace …. but thats another post !

An excellent, must read post from Mark Brinkley  – Is the prince igniting a civil war?  – guest blogging on Phils Zero Champion blog  – sets the scene for a roundhead v cavaliers schism on zero carbon homes, code level 6 and all that …..

Code level 6 too easy ? – go to level 7 or beyond

Leave a reply

Following on from earlier posts (whats wrong) on this site where I raised the question that Level 6 of the Code for Sustainable homes was seemingly too low a standard – as Barratts and Eddie Shah, and others, already claim they can achieve it , apparently without doing to much different, it is encouraging to see Bill Dunster pushing the goal posts further.

‘Anybody can build to Level Six,’ says Bill

Bill Dunster claims his RuralZED house, which will be shown at the Ecobuild exhibition (26-28 February at Earls Court), meets the unprecedented (and non-existent – he invented the term) Level Seven of the Code for Sustainable Homes, with a wind turbine producing energy to make up for the embodied energy in the materials and construction of the structure. more info at AJ

Level 6 and now Level 7 must remain stretch targets – targets to stretch our rethinking, our innovations and our urgency in addressing sustainability issues. To say we can achieve them today is plain greenwash. (Greenwash sin number 1, 2 3, or 6? )

And, on a similar issue will we see a higher level BREEAM assessment to continue to stretch our sector? After all if BREEAM Excellent doesn’t achieve the targets we need to reach nationally or globally then indeed we do need higher, tougher standards.

As Dr Jo Williams, in the latest edition of Journal of Environmental Planning and Management shows, the current government strategy is unlikely to drive the required increase in technological, infrastructural, service and knowledge capacity needed to deliver zero-carbon homes. If it is going to meet its carbon targets the government should make the current “code 6-star rating” (ie zero-carbon standard) mandatory for all new housing, and invest in the technology, infrastructure and knowledge needed to support its delivery… Without which we will head to an environmental disaster. (Guardian report – where are the green houses)

Or – the will (hearts and minds) and motivation to do so without legislation and standards – ie just getting on and doing it as in the spirit of Contraction and Convergence for example – but thats another post.

Whats wrong with Code level 6 – a more informed view…

CarbonLimited have posted a more informed and detailed view on whats wrong with the Code:

The requirement for all homes to be zero carbon by 2016 is going to fail unless we take action now. In particular, a set of interim requirements under the Code for Sustainable Homes must be imposed on private house builders. In addition, the Code must allow more flexibility in how zero carbon is achieved … continues

Is code level 6 enough?

Am I missing something here.

I was encouraged by the inclusion of what I took to be a stretch target – level 6 in the Sustainability Code. Yes a stretch target for 2016, one that would drive innovation and improvement in construction, design, micro generation, energy suppliers and all the other necessary components. And one that would drive the real collaboration of all these sectors. To deliver by 2016.
And yet here, some 8 years away from that date, we are already letting contracts for level 6 (Hanham Hall) saying we can deliver (Barratts). Even failed newspaper baron Eddie Shah is reportedly building low cost homes that meet level 5.

So maybe we need something more stretching that will make us rethink our approach to sustainability.

We also have a fair amount of doomsaying – that it is not feasible, not practical, not necessary or will cost far to much.  Isn’t this to be proven or dis-proven by working towards level 6?

I see a similar reaction to the Code as we did to Egan’s Rethinking Construction – we didn’t need it, we couldn’t do it – it will cost too much and then suddenly with a great coat of whitewash everyone was Egan compliant. (Strangely linked to funding!) And now looking back nearly 10 years after Egan we see what a significant catalyst that was.

So, a thought for the holiday period – Standing in the future of 2016, in a carbon zero built environment, what message would you send back to todays industry leaders, influencer’s and politicians. (A nice seasonal Dr Who link). Would it be strive for level 6, do something beyond level 6 – or give up on it all together?

Carbon off setting not permissable on zero carbon projects

Been looking at site that mention Hanham Hall – the first Zero Carbon Challenge project recently let to Barratts.  The local BBC Bristol  site contains these wonderful comments from English Partnerships:

Unlike carbon neutral developments, there can be no conscience-clearing carbon off-setting on a zero-carbon project. 

No carbon footprint must be left at the site whatsoever and other developers will watch the Hanham Hall winner hawkishly as from 2016 all new homes must be zero-carbon.

The South West Director of the agency, David Warbuton, said a new eco-friendly chapter was beginning in the history of housebuilding: 

“I think humankind has always evolved according to local and environmental conditions and, as slate replaced thatch 400 years ago, that’s all we’re talking about here.  We’re at the next stage of building and community evolution.

Now it starts to sound more like a challenge.  Making the construction process itself zero carbon would be challenge enough considering the high carbon emissions of transportation and cement products.  We will learn allot from this project

Code level 6 builder announced for eco village number one

Leave a reply

From the Communities and Local Governmnet website:

Housing and Planning Minister Yvette Cooper today announced details of the housebuilder who will build England’s first eco-village.  Barratt Developments PLC has been selected by English Partnerships, the Government’s National Regeneration Agency, as the preferred developer to create a new community at the site of the former Hanham Hall Hospital near Bristol. Homes on the site will meet the Government’s most exacting eco standard – Level 6 of the Code for Sustainable Homes.

This is a site and location I know very well … being close to the area I grew up in and cut my teeth in the industry as a site engineer a few years ago (!) …  aware of the campaigns by local residents not happy with plans to turn a former farming and greenbelt area into housing … so a project I will watch with interest.

And therefore also of interest on a wider sustainability issue:

… this ground-breaking project will create eco lifestyles. It will hand over a listed building to community use, capture rainwater and include sustainable drainage, farmers’ shops, a car club and bicycle storage.

One of the excellent articles on the new Building Sustainability site is The Year to Zero.  putting many of the important targets and objectives being set for our industry in a chronoligical count down to carbon zero, neutral or ‘sustainability’. (or wherever its is deemed we need to be)
The article, in conjunction with Fulcron Consultaing will be updated as and when more targets are set, so definelty one to watch.

I use a similar approach, looking into the ‘planned future’ for our sector, helping organisations set their own strategies and targets, on green and other related topics.  How do your business or improvement plans map onto this timeline?  Will you be ahead of the game, prepared, or lagging and playing catchup? Do you even have a route-map to get you there?

the Code …from denial to despair?

The cost of achieving carbon neutral or zero homes to the Code keeps raising its head, as Phil over at Sustainability Blog points out.

I didnt catch the UCT speakers name on the US Greenbuild365 live webcast testerday, I was listening rather than watching, but a sound bite delivered with typical American style caught my ear…“The building sector is over-estimating the cost and under-estimating the impact of climate change issues”

How true, when we think about the moaning around the cost of the new Code for Sustainable Housing, which will be seen as a smokescreen for reluctance in doing anything at all.

Jonathan Porrit writing in his blog and in BD… makes the point well… why put a price on the importance of carbon free homes?

Government policy is being applied to decarbonising both new and existing housing, with Building Regulations and the Code driving that transformation. An industry that has lived for far too long in a feather-bed world, where nobody gave a tinker’s cuss about energy and resource efficiency, is being incentivised to change, and is marketing to rapidly rising consumer expectations. So why would anybody suppose that the combined genius of architects, designers, engineers, builders, surveyors and planners isn’t going to be able to come up with the zero-carbon goods?

I live in weird world these days. Having spent most of my life described as a prophet of doom, I now find myself having to shake people out of a fatalistic “can’t be done” mind-set! We seem to have moved from denial to despair in one effortless leap. So let’s get our creative act together here. After all, we don’t have a choice about this. Either we rise to this challenge, or the mealy-mouthed, risk-averse mediocrity that dominates this particular industry will take us all down with it.

The costs arising from inefficiencies through waste, poor project management, incorrect procurement, lack of working together, poor design, legal fees to check contract documentation and all the well documented historical ills of our sector etc far far outweighs the cost of achieving the Code… surely?

Acheiving the code needs a different mindset, as Einstein said… we cannot solve todays issues with the same mind set that created them in the first place...

By rearranging the debate towards opportunity we can can move from despair to exciting.
