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

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

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

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

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.
