Ecobuild - Tuesday 02 March

Simplifying standards, guides & tools

Never before have those working in construction and the built environment had to respond to so many new and revised standards. This stream dealt with the more understood as well as the emerging standards. It also explained the connections between them, and some of the tools and guides which are starting to become available to help designers and specifiers.

All sessions took place in the RICS Theatre

10.30 – 12.00

There’s no haus like Passivhaus: exploring the standard, doing the sums

Sustainability tools for building procurers

Procuring sustainable buildings is a new notion. And whilst there are an ever increasing number of regulations, standards and codes, bringing them together and underpinning them with a reliable commercial assessment is challenging. This session explores a toolkit designed specifically to make this processes understandable and achievable, and looks also at the guides most helpful to procurers.

chair: Tony Nuttall, Associate, Cole Thompson Anders

12.30 – 13.00	Green guide on a construction materials rating
	Jane Anderson, Principal Consultant, BRE

13.00 – 13.30	Case study: East Midlands Development Association's Sustainable Procurement Toolkit
	Tony Nuttall, Associate, Cole Thompson Anders

13.30 – 14.00	Towards Zero website demo which shows how to best reduce the carbon impact of an existing home
	Ian Byrne, Deputy Director, National Energy Foundation

Understanding revisions to SAP

SAP - 'Standard Assessment Procedure' - for energy rating of dwellings provides a simple means of reliably estimating their energy efficiency performance. The next edition of SAP (due in the latter part of 2009), will come into effect for Building Regulation purposes, when the 2010 amendment to Part L comes into force. The 2009 edition will incorporate several changes aimed at improving the accuracy of SAP assessments of very low energy dwellings that will become the norm for all new homes built to low and zero carbon targets. This session examines the revised SAP and impact of those changes.

chair: John Tebbit, Industry Affairs Director, Construction Products Association

14.30 – 14.50	What are the key technical changes to SAP?
	Dyfrig Hughes, Principal Consultant, National Homes Energy Rating, National Energy Services

14.50 – 15.30	SAP, the new Part L and what it means for housing specification
	Nick Jones, Associate Director, Inbuilt Ltd

15.30 – 16.00	The future of SAP and the role of industry in its development and funding
	John Tebbit, Industry Affairs Director, Construction Products Association

4D cost modeling - an holistic approach to whole life costing

Achieving an economic justification for sustainable design and construction remains challenging. But is that because the case is being based on the wrong criteria? This session look at an holistic way of assessment – the four dimensional cost model (4DCM) - a dynamic life cycle model measuring capital cost, replacement cash flow, SAP, CO2 emissions, embodied energy, and running costs.
