Why is Sustainable Construction necessary?
The carbon emissions from the production and
transport of construction materials are a
significant part of the construction industry

• Combined, materials production and transport make
  up 44 of all construction related emissions
• Improved extraction, manufacturing and sourcing
  processes
• Recycling of materials
• Local sourcing
• 72 of a buildings life cycle carbon is embedded
  into the physical asset

Material Resources

• The Construction Industry uses 420 million
  tonnes of materials a year
• At present 22.5 of the 90 million tonnes of
  waste that go to landfill from the construction
  industry produces a year is unused materials.
• The South East (excluding London) was found to
  be the biggest producer of construction and
  demolition waste, producing 18 of the overall
  total, of the nine English planning regions and
  Wales, according to the Environment Agency and
  DETRs study in 2000.

WDC - Sustainability Approach

• Responsive to brief, client and budget
• Inclusive design team and users
• Art and innovation as integral part of the
  project
• Whole environment and lifecycle considered
• Design starts and stays green
• Design led, people centred
• Outcome focused

• EMS - ISO 14001
• Monitoring eKPIs
• Capacity Building
• BREEAM Team
• Re-thinking

Hampshire Core Strategy Sustainability Policy

• The Core strategy focuses on
• Green Infrastructure
• Natural Habitats and Wildlife
• Renewable energy
• Environmental Impact of materials
• Water
• Waste

Utilising the Code for Sustainable Homes and
BREEAM as key tools in monitoring

Hampshire Core Strategy Sustainability Policy

• Sustainable Code for Homes
• Will require 10 renewables climbing to 15 from
  2016
• Continual improvement in use of A rated materials
  in major building elements
• Use of SUDS to attenuate hard surfaces roofs
• Household recycling facilities for at least 3
  waste streams, composting and SWMP for
  construction.

Hampshire Core Strategy Sustainability Policy

• BREEAM rating of Very Good increasing to
  Excellent by 2012
• Minimum score of 60 in Water
• e.g. Schools would require
• water consumption of 1.5-4.4m3/person/year
• pulsed water meter to each building
• proximity detection shut off for all urinals and
  WCs
• Water recycling for 50 predicted
  rainfall/predicted flush demand.
• Minimum 55 in Energy (60 retail)
• e.g. Schools would require to achieve all credits
  including free cooling and a 10 improvement over
  the Approved Document Part L2A 2006
• Minimum 55 in Materials (60 retail) increasing
  to 70 by 2012
• e.g. Requires use of A rated materials, recycled
  aggregates, responsibly sourced and re-use of
  façade and structure.

Hampshire Core Strategy Sustainability Policy

• Impacts
• Sustainability is often a desirable and not a
  core requirement
• The Hampshire Sustainability Policy is a welcome
  change
• Its a driver for change
• It will have a positive impact on the
  Construction Industry and our clients
• But it will come with capital cost
