What is sustainability?
‘Sustainability is the OPTIMISATION of financial, human and environmental capital.
Financial Capital – Cost savings, life-cycle-cost, productivity
Human Capital – Users, customers, shareholders, staff, community
Environmental Capital – Natural resource use, air quality, waste, water, recycling, energy.

Ways to Win with Sustainable Development
Why ? - The Drivers
Legislation – renewables targets, carbon taxes, efficiency requirements
Competition – Keeping up with enhanced building specifications and client demands
Volatility in utility prices
Economic slow-down – Producing an attractive product in a shrinking economy to maintain sales and rental returns.
Planning Requirements – The planning authorities are more often looking for a sustainable strategy to enhance the longer term value and viability of the development.
Ways to Win with Sustainable Development
Sustainability Initiatives…
35% green electricity by 2010 Reduce CO2 emissions by 35% per $m sales by 2007
World's first carbon neutral bank 1st 'zero carbon' branch in New York (Foster Tower)
Target of halving energy use in all buildings by 2010 Reduce emissions > 50% by 2020 3 No. model 'environmental' stores in the UK Water use reduction in the UK by 15% by 2008/09
Target of > 25% energy savings from today’s levels Powering building stock with green energy Scheme for stores to keep 10% of any energy savings

Costs and Benefits
Ways to Win with Sustainable Development
Where do sustainability costs lie….
Site specific
Upgrading of building fabric to reduce heating and cooling costs…..
0% to 5%.....
But it is possible to do this without significant cost increases…..
District heating/cooling – 2-3% of capital costs….
But does not have to hit your budget! AND can become a revenue stream
Construction cost increases…. The great unknown – practices will need to evolve to meet new demands
Other initiatives generally are not significant costs and are usually considered good design practice…..
