1 Sustainability labelling An overview Dr Hywel Davies, CIBSE Technical Director ECTP Conference 2009 Energy Efficient Buildings 24th November 2009, Brussels

2 CIBSE - Engineering Excellence To demonstrate and promote the quality of engineering design innovation and effectiveness create world-class businesses; to provide a benchmark of excellence demonstrate the power of engineering design, innovation, leadership, entrepreneurship and our young engineers. To meet the needs of Society by the practice of the art and science of engineering INTRODUCTION Excellence is the state or quality of excelling. Particularly in the field of business and organizations, excellence is considered to be an important value, and a goal to be pursued 2

11 Purpose of Energy Labelling Information on the potential and actual energy use of buildings Feedback to building owners and operators on how their building is performing Insight into the value and potential longterm costs of a building Intent of Energy Labels

12 Fixed building services & fabric in the base building: Fixed building services covered by EPCs and building regs Part L2: Heating, hot water, cooling, ventilation and lighting Fixed building services added in occupier s fitout: Fixed building services added in fitout, covered by building regs Part L2: Extra cooling, ventilation and lighting Equipment and appliances added in occupier s fitout: Normal equipment and appliances: Office equipment, electronics, laundry, domestic catering etc MIND HE GAP! Services not covered by building energy regs: Lifts, communications, security, emergency and outdoor lighting etc Fixed building services added in fitout, not covered by building energy regs: Communications, security, machine room cooling etc. Special equipment and services: Process equipment, commercial catering, data centre and server rooms

17 Environmental Labelling

18 International Standards for Sustainable Buildings Under development in ISO TC59 SC17 and at a European Level within CEN TC350 Set out general principles Deliver an overall framework for sustainability in relation to buildings STANDARDS FOR BUILDINGS 18

19 ISO TC59 / SC17 General Principles, Terminology, Sustainability Indicators full scope of sustainability Declaration and Assessment Scope on environmental aspects ISO TC59 / SC14 Design Life, Service Life, Life Cycle Costing, Link of environmental assessment to Service Life Links performance-based building and life performance to sustainable building concerns CEN TC350 Takes ISO SC17 & SC14 standards to European context With thanks to Dr Wolfram Elaborates on three spheres of sustainability Trinius, BuroTrinius 19 INTERNATIONAL STANDARDS ON SUSTAINABILITY IN BUILDING CONSTRUCTION

20 Sustainability in Building Construction General Principles Equity Global Thinking and Local Action Holistic Approach Responsibility Involvement of Interested Parties Long-Term Concern Precaution and Risk Transparency ISO 15392:2008 With thanks to Dr Wolfram Trinius, BuroTrinius 20

21 Core Sentence and derived Core Concept Sustainable development of buildings brings about the required performance with minimum adverse environmental impact, while encouraging improvements in economic, social (and cultural) aspects at local, regional and global levels. Economic, environmental and social aspects embedded in performance context Parallel consideration of environmental, economic and social aspects at hand of functionality & performance ISO With thanks to Dr Wolfram Trinius, BuroTrinius 21

22 Methodologies are flexible to adapt to decision making context Standards define the methodologies, not the detailed scenarios, nor the target values or benchmarks Labeling schemes need further conventions, as goal to: Compare and communicate simplified information Assess different buildings on common scale Common set of parameters regardless target audience Highly standardized detailed approach to ensure comparability Important: Add-on to standards, without conflict! METHODOLOGIES, STANDARDS, LABELING SCHEMES With thanks to Dr Wolfram Trinius, BuroTrinius 22

23 Environmental Labelling BREEAM, LEED, HKBEAM Greenstar All assess environmental performance of a building Environmental Assessment Methods

24 Assessment methods Generally share common DNA Environmental assessment varies from one territory to another Multi-variate comparing eg. energy or water use with transport provision Not yet standardised, although it is moving that way the methods came first, before the standards! What are the differences?

25 European Ecolabel for Buildings How does it differ from existing schemes and initiatives? Do we really know enough about how to do it? How will it add value over existing activities? European Ecolabel Initiative overload?

26 Smart ECO a sustainable vision for the future

27 Smart ECO What will be a Sustainable Smart Eco Building in 2030? Based on sustainability principles of ISO 15392

28 A Smart Sustainable Eco (SSE) Building will: 1. Apply the general principles of sustainability; 2. Result from the involvement of all interested parties and be designed to meet its occupants needs individually and collectively; 3. Be completely integrated into the relevant local building, town-planning or environmental planning schemes and infrastructure; 4. Be designed or refurbished from a Life Cycle perspective; 5. Have its environmental impact minimized over the estimated or remaining service life; 6. Deliver economic value over time ; 7. Provide social and cultural value over time and for all; 8. Be healthy, comfortable, safe and accessible for all ; 9. Be designed or refurbished to be user-friendly, simple and cost effective in operation, with measurable technical and environmental performances over time; 10. Be designed or refurbished to be adaptable throughout its service life, with an end-of-life strategy;
