CARBON
• 34% cut by 2020; 80% by 2050• 5 year budgets; independent
Committee; annual report to Parliament
• Extensive enabling powers

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 non-domestic buildings to be zero carbon by 2019

“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”.

The Carbon Hierarchy

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

Elizabeth Fry Building
Constructed by Willmott Dixon 1993/4 and occupied in January 1995
The Probe Team measured energy performance and user satisfaction:

Value Engineering

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.

Air tightness < 1 m3/hr per m2
Heating requirement < 15 KWh/m2a
Primary energy demand < 120 KWh/m2a

In conclusion ………………….
"We cannot solve our problems with the same thinking we used when we created them."

The Journey – Leadership from Government
The Journey – Leadership from industry
Never Waste a Good Crisis
Develop a New Generation of LeadersWe 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 ChangeBusiness 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 ValueAll customers in the chain need to professionalise their procurement to achieve best value, rather than focusing on lowest price.

Lessons Learned - ZC Buildings Journey
1. Leadership2. Re-Thinking/sustainability workshops ……from ‘inception’3. Sustainable Procurement (decisions based on whole life costs)4. Partnership approach – inclusive from the start5. Integrated design team, contractor, client, user & supply chain6. Carbon Manager on every project………………with ‘clout’!7. Building to be part of the curriculum and engage users8. Transparency – learn from mistakes and publish, warts and all!9. Post Occupancy Evaluation & Soft Landings Framework10. Incentivise performance and celebrate success
