RICS – eco-harmful claims?

Recent research and claims from the RICS that some energy measures recommended in EPC’s may take up to 208 years to recoup costs has been widely commented on – in Saturdays Telegraph,(solar heating saves energy, wastes money) in Building but with more astute comment from Phil at SustainabilityBlog and at CarbonLimited.

This approach obviously damaging to the homeowners motivation in improving existing housing stock, or indeed other environmental initiatives, and maybe another eco-harmful shot in the foot from the RICS
There is also the underlying debate about the method of calculation of energy savings, and indeed energy costs.  Following the debate through CarbonLimited and the Grist article that argues electricity costs are political and not economic

Solar building design

One of the fascinating things behind the statistics to running a blog is the search items people use to end up here at isite.

Still by a large margin is the search for a good construction carbon calculator.  However coming up fast on the inside, is the search of things solar relating to energy and building design.  This has led to me to brush up on my knowledge – and found this fascinating wikipedia entry. Passive solar building design

 Passive solar building design involves the modeling, selection and use of appropriate passive solar technologies to maintain the building environment at a desired temperature range (usually based around human thermal comfort) throughout the sun’s daily and annual cycles. As a result it generally minimizes the use of active solar, renewable energy and especially fossil fuel technologies.

I would add into this the passive solar lighting concepts of sun-pipes, light tubes and wind pipes which we use to great effect here.  Having daylight and fresh air into the middle of the house is wonderful – and saves on lighting energy and costs, even on overcast days.

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…)

Merton Rule – why is it important

One of the key themes emerging at the Conservative conference fringe events attended yesterday and today was the future and the importance of the Merton Rule.  Cutting through the rhetoric found at any political party event, there were interesting and important comments from the Micropower Council. citing the current political football being played as possible serious consequences for the industry

The Merton Rule, also known as PPS 22, requiring a proportion of any development to source energy from alternative means, is driving the devlopment, capacity and skills of the mircopower companies, that in time will become essential in meeting targets such as the 2016 zero carbon homes.

Take this in conjunction with the recent Mind the Skills Gap skills report , and we could be heading for a problem of skills and knowledge to achieve targets and milestones.

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.”

(BBC)

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

zero carbon Britain ??

Following on from yesterdays post on the Lib Dem’s vision for a zero carbon Britain… one with no fossil fuel cars and a zero carbon built environment by 2050 -Leo Hickman considers the implications in today’s Guardian and rightly points out that the Lib Dems may have stolen the clothes from the other parties, albeit temporarily.

Are we seeing a rising in the ante of carbon  politics? along with a new zeitgeist of green taxes and green mortgages?

The fight is has commenced for the greenest party.  One wonders where the Green Party will position itself, or has it achieved its aim of bringing green issues to the top of the political and corporate agendas?

Lib Dems view on low carbon housing

In what will most likely be the first of many reports, papers and manifestos as we approach conference season and elections, the Lib Dems have set out their vision of a zero-carbon Britain by 2050 when it published the most ambitious blueprint for climate change reform ever produced by a mainstream political party. (Guardian article here)

On housing the blueprint covers

Introducing ‘green mortgages’ to enable people to make their homes more energy efficient. (see previous isite post)

Cut carbon emissions from new buildings by 95 per cent compared with our existing housing stock by ensuring that all new homes have to  be built to the GreenHouse standard no later than 2011

Ensure that the housing stock is completely updated by the year 2050.

Ambitious maybe but the pattern has been set for the other political parties to follow or address.

Certificates don’t cut carbon emissions, people do
