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

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.

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
