Understanding the problems of 1960’s and 1970’s University Estate Buildings
Issues Facing University Estates• Attracting students - Recruitment• Retaining staff & students - Retention• Cutting edge research - Performance • Sustainability / Whole Life Costs
To demolish or refurbish?
‘The way people feel and behave while studying or working within buildings is linked to their overall satisfaction rates and level of happiness’
1960’s University Campus Buildings – Key IssuesBuilding Fabric•Glazing•Low Mass•Low Insulation•High Infiltration•Asbestos
1960’s University Campus Buildings – Key IssuesBuilding Services•Low efficiency lighting•Old heating plant•Highly Air Conditioned•No raised floor
1960’s University Campus Buildings – Key IssuesSpace Planning•can be deep floor plan•low floor to floor height•No raised floor – IT integration.•Internal divisions inflexible•Disabled access?
1960’s University Campus Buildings – Key IssuesExternal Factors• Heritage Listing• Masterplan/Estates Strategy• Statutory Compliance• Environmental Policy
1960’s University Campus Buildings – Key IssuesQuantitative characteristics•high glazing•can be deep floor planning•highly air conditioned •or totally naturally ventilated•low floor to floor height•No raised floor•Low mass – high mass can be revealed•Floor plan can be narrow•Poor insulation•High infiltration •Disabled access?•Contamination – possibility of asbestos•Defective “system” building•High Running and Maintenance Costs
Qualitative characteristics• Usability• Comfort• Delight• Future Vision• Affection from users• Listed/Heritage• CSR goals• Spatial aspects
Subjective Qualities / Strategy and Aspirations are also important drivers

1960’s University Campus Buildings – Review Criteria1. Physical Aspects• Gross/Net ratios• Plan Dimensions• Storey height• % Glazing (openable)• Construction System• Thermal Mass• Servicing• Air-tightness• Contamination – e.g. asbestos• Energy and Water Costs• Maintenance Costs• Obvious Problems
2. Functionality• Occupancy Evaluation• Comfort• Operation• New Education Methods• Technology Integration• Climate Change• Ongoing performance feedback
3. Future Vision• CSR• Master plan• Legislation• Estate Strategy• Budgets• Grants/funding• Operating costs

Our Approach
Our Approach1. Data Gathering•Questionnaire addresses• Physical Aspects• Functionality• Future Vision
•Selection of Long-List and Site Visits
Our Approach1. Data Gathering• Identification of Key Findings
• Energy Use & Maintenance• Environmental Comfort• Use of Space• External Cladding Performance• Capital vs Whole Life Cost Issues
Our Approach2. Production of draft Case Study Information based on Returns
Our Approach3. Data Evaluation•Assist in Consultation with other stakeholders – review of their methods e.g. MOD
•Develop Sustainability and Whole Life Cost Appraisal Models/ Draft Toolkit•Set Key Performance Indicatiors (KPI’s)
Our Approach3. Toolkit Assembly
• Toolkit Output (Report + spreadsheet form / could be web-base tool in the future).
• Presentation of Report and Demonstration of Toolkit Method
• What are the likely criteria on which the tool will be based?
A Successful Outcome4. Priorities
•A tool that enables decision making based on differing project priorities.
•Incorporates KPI’s and DQI’s
•Enables true ‘Sustainability Appraisals’ based on triple bottom line.
•Easy User Interface
•Product delivered to program
A Successful Outcome4. Time Frame
• May-June ‘07: Long List of projects• June-August ‘07: Site visits + Case Studies + Short List• Sept-October ‘07:Produce case studies• Oct-January ‘08: Produce Sustainability Appraisal Toolkit• March ’08: Launch & Presentation at the AUDE Conference
