Post-Occupancy Evaluation of Sustainable Education Development Projects

1. Post Occupancy Evaluation of Sustainable Development Projects in the Education SectorLeanne McMillan, Senior Consultant, BRE Scotland

2. Presentation Overview • Strategic Drivers for POE • POE – Why? What? How? • POE Methodology • Case Studies • Summary and recommendations

3. POE Strategic Drivers in Education Sector Core Strategic Drivers Material Choices Space Utilisation Value for Money? Community Whole Life Cost Economic Renewable Technologies Environmental Outputs Reduction CO2 Social Responsibility

4. POE – Why? What? How? • Identify any areas of improvement in terms of project delivery and performance with focus on the potential for increased efficiencies • Provide lessons that can be used to improve design of future projects • Highlight any gaps in communication and understanding between the designers, users and building managers that will impact on the building in operation • Produce benchmarking data to compare across projects and to demonstrate progress and continuous improvement over time

5. POE Methodology • Operational Review – 3 - 6 months post project handover • Post project review of design and procurement stage • Initial feedback from occupants on building performance • Functional Performance Review -12-18 months post project handover • Sustainability Audit of Functions • Design Quality Matrix • Architecture • Environmental Engineering • User Comfort • WLC • Detail Design • User Satisfaction • Occupant Consultation • Strategic Review – 3-5 years post project handover • Has building met original business case drivers – i.e. has Value for Money been derived? • Feedback for future projects

6. Sustainable Design Drivers in Education • Key business drivers for many Further and Higher Education establishments include: • The desire to enhance the learning experience • The provision of fit-for-purpose teaching spaces • Improved learning facilities • Ultimately achieving a low energy, high performing building • The quality of any building design not only greatly determines the impact that the building will have on the environment throughout its lifetime, it also has a significant impact on the occupants: • Overall health and wellbeing • Performance • Productivity of the building occupants

7. Sustainable Design Drivers in Education • Optimising the learning environment • An improvement in learning ability through increased natural daylighting • Daylighting factors of 4% - 6% can result in an improvement in learning ability of between 14 and 23% • An improvement in occupant health and wellbeing through efficient and effective lighting strategies • A healthier internal environment and 20-40% reduction in operational costs as a result of intelligent lighting systems • An improvement in occupant performance (as a result of thermal comfort modelling) • For every degree over 27oC, there can be a 10% reduction in occupant performance • An improvement on health and wellbeing due to the reduction of VOCs • Exposure to high VOC emissions can negatively impact on the health of occupants, particularly those with respiratory problems • An improvement in occupant response due to an increase in natural ventilation • Poor air quality levels of 2,700ppm CO2 can result in up to a 14% reduction in cognitive function
