NEWS MILKING IT
NG Bailey says off-site manufacture has helped it knock seven weeks off the delivery of a project at a £150m dairy in Aylesbury. It delivered 17 services modules in only fi ve weeks; the fi rm said it would have been a 12-week job using traditional construction methods at the Arla dairy. The modules form a 204m run of main services distribution and contain piped services including chilled water, low temperature hot water heating, steam and condensate, process ice water and glycol circuits. It also includes high and low voltage distribution and separate containment runs for data and building management system control cabling.
Clarity needed over allowable solutions
Potential investors in future zero carbon homes demand more details on the role and cost of ‘allowable solutions’
A report from the Zero Carbon Hub, which explains how ‘allowable solutions’ would work, has received high-level support from clients, fi nanciers and engineers.
It considers the role of investment in six potential solutions that could keep the government’s policy on track to deliver zero carbon homes from 2016.
Allowable solutions is a way of accounting for
some of the carbon emissions reductions that are diffi cult to deliver on site. The Hub calculates that residual emissions per property could amount to 10 to 14 Kg CO2
/m2 /year, depending on the i0522-43 Condair GS Gas-Fired AW_CIBSE Magazine 190x66 11/07/2012 12:42 Page 1
type of home. For a typical home, an allowable solutions payment would be about £1,200, based on the proposal that they should cover a 30-year
period and be paid at £46 per tonne of carbon. Allowable solutions under consideration would require housing providers to invest in the Green Deal; district heating; social housing retrofi ts; renewable energy projects; embodied carbon initiatives; and low-carbon lighting. The new report, Allowable Solutions –
Evaluating Opportunities and Priorities, measures the potential solutions against a series of critical success factors. The report identifi ed a need for certainty from government and agreement on key operational aspects of the framework, including price, verifi cation and fund management. The report also recommends a programme of trials to test the proposals and examine the real-life practicalities. The report fi ndings were widely welcomed. John Slaughter, director of external affairs at the Home Builders Federation, said there was considerable concern among developers about
the current lack of certainty – particularly the cost of the allowable measures. He called for the government to take the report’s fi ndings on board and develop ‘a workable and credible system’.
E.ON’s Marco Marijewycz added that the report had ‘the potential to catalyse cross sector innovation and the economic rejuvenation of our communities’.
Guy Battle from Deliotte LLP claimed it was ‘an innovative mechanism that will permit developers to deliver this requirement cost effectively’.
Battle added that it could ‘harness the creativity of the industry to inspire innovation in materials and systems, to create new jobs, drive growth and establish the UK as a leading low carbon economy’.
