  1. Seminar on Sustainable Buildings Nicosia, Cyprus – 16/17 May Prof. Dr. Ali Beba

  2. Sustainability in Building Significant improvements expected: • By reducing the environmental impacts • By anticipating and controlling long term costs • By more taking into account social goals and consequences of a construction SOCIAL ENVIRONMENT ECONOMIC

  3. Sustainability and the Build Environment Environmental • Huge long term storage of raw materials • Main responsible for the CO² emissions • Significant source of waste Economic • 2 digit % of the economic activity • The main part of the household budget • A favorite choice for long term investment Social • Creates social link or social discrimination • Protects or threatens inhabitants health • Transmits culture heritage to the future generations • Major employment offer

  4. Building materials are the basis for building performance CEPMC - Council of European Producers of Materials for Construction: • Buildings contribute for more than 40% on EU’s energy consumption and CO2-emission • 85% environmental load dwellings during the use phase: info technical & environmental information • Selection of building products on environmental performance should be done by assessment at building level • “Environmental Product Declerations” are the basis for the assessment: LCA-based

  5. EPD’s in the Building Sector Environmental Product Declaration – Many initiatives from industry, government programs, commercial interests, etc. – Based on various, similar, sometimes comparable schemes – EPD’s already available in many EU-countries: Germany, France, UK, The Netherlands, UK, Sweden, Denmark… – EPD data available; on-line. data base: Simapro; INIES, GABI, …..

  6. Many EPD’s already available • In the Netherlands: • > 200 manufacturers • > 30 product groups: metals, bricks, roofs, insulation, etc. • In Germany: • > 30 manufacturers • 9 product groups • In France: • 40 EPD’s • 20 product groups

  7. ISO/TS 21931-1: Sustainability in Building Construction – Framework for Methods of Assessment for Environmental Performance of Construction Works Based on the premise that sustainable construction brings about the required performance with the least unfavorable environmental impact, while encouraging economic, social and cultural improvement at a local, regional and global level. Aims: • Examine the ability of the building to contribute to sustainable development with regard to environmental dimension • Communicate and/or improve the building’s environmental performance of the building

  8. Aspects of Sustainable Buildings

  9. Minimum Requirements for the Assessment of the Environmental Performance of a Building Valid for; A) Newly built or refurbished buildings B) Existing buildings (in chapter 5 of the ISO 21931) • Documentation of the assessment method • Elements of the assessment method

  10. Issues for Environmental Assessment Environmental performance will be assessed according to environmental issues that are of concern to the various interested parties:

  11. Issues of Concern - Environmental Impacts of Buildings • Climate change, • destruction of ozone layer, • destruction of non-renewable sources, • formation of photochemical oxidants, • acidification of land and water and • eutrophication

  12. Issues of Concern - Environmental Aspects Issues related to energy and mass flow during the life cycle • Material use • Depletion of non-renwable resources • Use of renewable material resource • Use of substances classified as hazardous or toxic according to national / international regulation • Primary energy use • Depletion of non-renewable primary energy • Use of renewable primary energy • Water use • Land use • Waste production • Reuse / recycling or energy recovery • Waste production for disposal

  13. Issues of Concern - Environmental Aspects Issues related to local impacts • Soil • Ground water • Noise • Odours

  14. Issues of Concern - Environmental Aspects Issues dealing with impacts on local environment • Wind damage by the microclimate around building, including tunnel effect • Load on infrastructure • Sun shading and glare on the property in question and any neighbouring property

  15. Issues of Concern – Building Management • Limitation of waste production • Recovery of waste • Reduction of nuisances • Control / reduction of pollution • Water saving • Wastewater treatment • Maintenance • Rehabilitation of the environment to promote biodiversity • Environmental emergency management

  16. Issues of Concern – Indoor Environment • Indoor air quality • Quality of ventilation • Hygrothermal conditions (air temprature and humidity) • Noise and acoustics • Glare, access to daylight and extreior views • Quality of light • Odour conditions • Quality of water • Intensity of electromagnetic fields • Radon concentration • Hazardous substances • Existence of unwanted micro-organism

  17. Quantification of Environmental Performance • Data quality • Transparency • Traceability • Reference levels • Weighting • Information sources

  18. Examples of Environmental Aspects • Total CO2 emissions (environmental loadings) • Contribution to climate change in terms of total CO2 equivalents (environmental impacts) • Distance from the building to public transport services considering the route frequency (consequental indicator)

  19. Examples of Social Aspects • Quality of buildings as a place to live and work • Building-related effects on health and safety of users • Barrier-free use of buildings • Access to services needed by users of buildings • User satisfaction • Social cohesion and participation of users and other intrested parties in the building process • Architectural quality of buildings • Protection of cultural heritage

  20. Turkish Technology Platforms • Automotive Technology Platform • Textile Technology Platform • Metal Technology Platform • Electric and Electronic Technology Platform • Marine and Sea Technology Platform • Energy Technology Platform • Pharmaceuticals Technology Platform • Agriculture Technology Platform • Construction Technology Platform

  21. European Construction Technology Platform – ECTP (www.ectp.org)

  22. Turkish Construction Technology Platform (TCTP) TCTP was established in November 2006 after a series of national meetings Operating by a core-group of 4 institutions: • Turkish Ministry of Public Works and Settlement • Chamber of Architects of Turkey (CAT) • Middle East Technical University (METU) Department of Architecture • Building Information Centre

  23. TCTP (www.tctp.org)

  24. Aims and Targets of the Turkish Construction Technology Platform • Create a platform where all the actors of construction sector can come together for ideas exchange. • Draw a road-map for the sector with an aim to develop short/medium/long term strategies. • Encourage the sector members to have more active participation in the EU Framework Programs, as well as to search way for the more efficient use of national resources. • Coordinate research work operated separately in various fields of the sector. • Encourage R&D work and to establish a dialogue for research-oriented partnerships within the sector.
