Journey to zero carbon education buildings George Martin Head of Sustainable Development Willmott Dixon Member Zero Carbon Task Force

The elephant in the Boardroom ! CARBON

Climate Change Act • 34% cut by 2020; 80% by 2050 • 5 year budgets; independent Committee; annual report to Parliament • Extensive enabling powers Climate Change Act November 2008

2008 Budget Already have all new homes to be zero carbon by 2016 All new schools to be zero carbon by 2016 Ambition for all new public sector buildings to be zero carbon by 2018 Ambition for all new nondomestic buildings to be zero carbon by 2019

Sustainable Procurement…? “Sustainable Procurement is a process whereby organisations meet their needs for goods, services, works and utilities in a way that achieves value for money on a whole life basis in terms of generating benefits to society and the economy, whilst minimising damage to the environment”. Definition from the Sustainable Procurement Task Force Procuring the Future – June 2006

Sustainable Procurement Challenge – Flexible Framework y e urn o nt j e m Pr e cur o Benchmarking how well you are addressing your sustainability issues against how well others are addressing theirs

The Carbon Hierarchy Source: HEFCE January 2010/01 adapted from the DCSF Zero Carbon Task Force and Parkin

Carbon Hierarchy Halve the demand, double the efficiency and halve the carbon in the supplies and you are down to one -eighth of the emissions Bill Bordass – Member of the DCSF Zero Carbon Task Force

Value Engineering or do you mean Cost Cutting? In particular be wary of cost cutting on: • Fenestration and rooflights: Especially where rooflights are central to the daylighting and/or ventilation strategy. St Francis of Assisi Liverpool

In conclusion ………………….

Re-Thinking…………………. "We cannot solve our problems with the same thinking we used when we created them. " Albert Einstein

The Journey – Leadership from Government

The Journey – Leadership from industry

Never Waste a Good Crisis Develop a New Generation of Leaders We must develop a new generation of leaders who can communicate their vision and drive change in culture and behaviour Adopt New Business Models that Promote Change Business models are fundamental to changing behaviour. We must move away from models that encourage short term thinking and find ways to incentivise long term value creation Procure for Value All customers in the chain need to professionalise their procurement to achieve best value, rather than focusing on lowest price. Andrew Wolstenholme October 2009
