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.

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.


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


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…..

Sustainable Procurement

- NI Government example


Sustainable Construction Grouphttp://www.cpdni.gov.uk/index/guidance-for-purchasers/sustainable-construction.htm

December 2004

Chaired by CPD – includes centres of procurement expertise and government construction clients in NI

Set guidance for the implementation of the ‘Sustainability Action Plan’ and ‘Achieving Excellence in Construction Procurement Guide 11 : Sustainability’

6 no. Guidance Notes

- General

- Targets for recycling

- Waste (including SWMP’s)

- Bulk materials / aggregate re-use

- Considerate Constructors

- Demolition, Dismantling, Recovery, Re-Use


By March 2006……..

All new projects to carry out environmental assessment using BREEAM or equivalent, all new build projects to achieve an ‘excellent‘ rating. (Refurbishment projects to achieve at least

‘very good’ rating.)
