Some issues remain… • SAFETY in construction • HEALTH of site workers • DIVERSITY in professionals
Strategic decision making • Reviewing strategic investment decisions on the basis of carbon? • When would carbon intensityover-ride cost? • Can we guide capital investmentand operational budgets? • Capital premium for long-term lowenergy consumption? • Pay-back periods and discount rates?

20:20 hindsight would be great • What are the risks? • Climate change uncertainty means uncertaintyfor any design specification • Legal action if infrastructure fails? • Code evolvement • Zero new carbon homes by 2016 • Zero carbon new non-domestic buildings by 2019 • Can codes change fast enough? • Skills development, knowledge transfer, tools
Can we predict what will happen? • Shorter design life? • Infrastructure / buildings, e.g. London 2012 Games has 100+ non-permanent structures • Standards & materials will change? • Recyclable / reusable • Built Environment professionals need to be ≥3 years ahead of society • In old money that’s ≥6 years…
