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

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 EUs
  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
EPDs in the Building Sector

• Environmental Product Declaration
• Many initiatives from industry, government
  programs, commercial interests, etc.
• Based on various, similar, sometimes comparable
  schemes
• EPDs 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 EPDs already available

• In the Netherlands
• gt 200 manufacturers
• gt 30 product groups metals, bricks, roofs,
  insulation, etc.
• In Germany
• gt 30 manufacturers
• 9 product groups
• In France
• 40 EPDs
• 20 product groups

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 buildings
  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

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 RD work and to establish a dialogue
  for research-oriented partnerships within the
  sector.
