Story of the CSH so far 6) Six level rating system – a tool

requirement


1) Appoint an assessor - Design house and site to achieve necessary total points score
- Dont forget mandatory elements!
- Using 'pre-assessment estimator' 5) Assessment report compiled and submitted to BRE for verification -Assessor completes assessment of performance using online reporting tool
-Report submitted to BRE for rigorous quality assurance checks
-Credits found to be wrongly awarded or without sufficient evidence will be ‘redballed’ by BRE quality auditor
-Report sent back to assessor with errors flagged
-Assessor reassess/augments evidence base/removes credit and resubmits report The challenge...circa 2001 The average new-build home (Part L 2006):

- Takes 5.76m3 of timber, 5000 bricks, 75 litres of paint to build
- Produces 3.6 tonnes CO2 each year through the use of space
heating, hot water, lighting and appliances
- Produces 1.3 tonnes of waste each year
- Consumes 219,000 litres of water each year more for less? Government response
circa 2001 circa 2003 But what about environmental limits?
...circa 2007 Result? - “Twenty-nine per cent of new estates in our audits were so poor that they should not have received planning permission” CABE 2006 Market Audit

- “Housing growth is taking place in severely water-stressed areas. There are serious concerns about whether these areas will be able to cope with increased demand” Sustainable Development Commission 2007

- "We can therefore estimate two million new homes have been rubber stamped for delivery over a mere 10 years. Built in the unsustainable, sprawling, manner that current models espouse, these homes will have a deleterious effect on both the urban centres from which they feed and the countryside that they encroach"
The Prince's Foundation for the Built Environment, 2007

- "There is also something seriously wrong when new houses across the country form rootless estates and could just as well be in Beijing, Buenos Aires or Belfast. These are developments which have no regard for a community's sense of place, belonging or identity. I fear we are building the slums of the tomorrow but it shouldn't be.” Lord Rogers, 2008


‘Lenders won’t lend, borrowers can’t borrow, builders can’t build and buyers can’t buy’. STOP PRESS!
circa Sep 2007 'Never waste a good crisis!'
circa Dec 2008

- Launched four months early in December 2008
Brought together the functions of EP and Housing Corp into a single organisation.
- £13 billion to be invested up to March 2011 - about £7bn in this financial year but reducing to £6bn in 2010/11.
- Agency’s National Affordable Housing Programme (NAHP)
- Kickstart funding for stalled housing and regeneration schemes

Around half of the 260,000 new homes projected to be built in England during 2009 and 2010 will be directly funded by the Homes and Communities Agency
A green and soft landing for housebuilding industry
circa 2009 Likely effect
circa 2010 onwards “ As every hunted animal knows, it is not
how fast you run that counts, but whether
you are slower than everyone else.”

01923 664747 3 million new homes by 2020 “Our analysis has shown that for Code level 3, the most common level built, there has been reduction in additional costs of around 6 per cent since 2007 as builders gain experience and supply chains are established.” (CLG, Sustainable New Homes – The Road to Zero Carbon Consultation on the Code for Sustainable Homes and the Energy Efficiency standard for Zero Carbon Homes, December 2009)

Costs -Under current version of the CSH
-May need for validation of planning application
