In particular be wary of cost cutting on:
• Fenestration and rooflights: Especially where rooflights are central to the daylighting and/or ventilation strategy.

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.
