Sustainable Estate Development
Graham Bell, Depute Director,Estates & Buildings Department
Sustainable Development
• Context
• Our Approach
• Project Example
• What’s next
Why adopt sustainability ?...External Drivers
• Climate Change (Scotland) Act 2009 (42% climate emissions reduction by 2020)
• Funding and Research Council pressure
• EU Emissions Trading Scheme
• UK Carbon Reduction Commitment (CRC) (tax costing nearly £1m per year)
• EU Energy Performance of Buildings Directive / EPCs
• Edinburgh Standards for Sustainable Building
…plus rising standards every 3 years as a result of EU legislation and the Sullivan Report
Why adopt sustainability ?...Internal Drivers
• Utilities Policy 2003 – adopted BREEAM
• Contain rising energy costs / reduce maintenance burden
• Universities & Colleges Climate Commitment /- promote ourselves as pro-active agents
• Universities that Count / Green League - benchmarking Student and Staff expectations
• Strategic Plan 2012-2016 – infrastructure enabler/social responsibility theme
• Social Responsibility and Sustainability Strategy 2010-2020
• Climate action plan 2010-2020
• Estates Strategy 2010 – 2020
• Keep well out of the Courts!
Project Management Process Map
AB13: Establish Sustainability Strategy
C3: Update Brief & Sustainability Strategy
Sustainability Strategy Template (T46)
Covers BREEAM sustainability criteria:
• Location and orientation of building
• Renewable energy; energy consumption; renewables; CO2;
• Whole Life Costing
• Ventilation; water usage
• Construction waste
• Transport
• Adapting to climate change
• Materials selection
• Pollution prevention
• Ecology and biodiversity
• Sustainable urban drainage systems (SUDS)
Construction based on:
• Sustainability principles• Selection of team / contractor• Workshop to start• Life time approach
– set best practice standards– Establish sustainability guidelines
for design team / contractor– Maximise efficient use of energy,
materials
Case Study
King’s Buildings Library - Approach
Case Study
King’s Buildings Library - workshop
Comparison and assessment of forms of construction to achieve most sustainable form of construction:
• Traditional masonry construction: not used (slow, inflexible)
• Timber kit construction: considered for ground floor use
• Engineered timber kit construction: considered for use at upper levels
• Solid wall construction: considered for areas requiring fire protection
• Lightweight cladding construction: not used (higher maintenance cost)
• Terracotta construction: not used (outwith budget)

The industry benchmark / one way we signal what we seek from Design Team and Contractor:
• Target Outstanding: 1
• Certified Excellent: 2
• Target Excellent: 3
• Certified Very Good: 5
• Target Very Good: 6

• Three Energy Centres
• 12% emissions reduction
• 8,500 tonnes CO2 less / yr
• Moved EPC score up by 2
• Generate £1m+ savings / yr
Complying with further expectations from Government / funders:
• Corporate Target
• Corporate Policy
• Measurement
• Procurement
• Supply Chain
• Reporting
… complementing our 67% Waste Recycling on campus
Environmental Sustainability
Zero Waste Scotland / WRAP
Emphasis on re-using existing buildings for new purposes:
Social and Cultural Sustainability
e.g. Old Royal High School becomes the Edinburgh Centre for Carbon Innovation
Sustainable Development
What’s next?
• BREEAM Education standard
• Challenging Carbon Targets – how far can we go? (scattered estate)
• Rising Energy Costs / consumption – business driven
• Carbon footprint – 2025 Estates Study
• Guidance on aspirations / expectations
