1. Introduction
Sustainable Development is the "development which meets the needs of the presentwithout compromising the ability of future generations to meet their own needs"(Brundtland Report: Our Common Future, 1987)
The 3 main pillars (dimensions) of sustainable development
ENVIRONMENT
Ecosystem integrity
Reproducibility of
natural resources
Biodiversity
ECONOMY Growth of employmentand income

The impact of construction sector on sustainability
The construction sector exercises a wide influence on the rest of society,having huge impacts on
. THE PLANET
The Construction Industry consumes 50% of
the raw material extracted from the Earths
Crust
The waste arising from the construction
related activities consists of a third of the
total waste, 970 million tones, produced in
EU
Constructions comprises the largest energy
consuming sector in Europe with almost
half of the primary energy used

The building sector has major economic
impact which has traditionally been the maineconomic background of the EU coutries
The majority of EU Countries buildings
constitute over half of the national wealth
Construction is the largest industrial sector in
EU, representing a quarter of the total output

COST Action C25
European COoperazion in the field ofScientific and Technical research
COST is an intergovernmental framework for European Cooperation in Science
and Technology, allowing the coordination of nationally-funded research on a
European level.
COST contributes to reducing the fragmentation in European research
investments and opening the European Research Area to cooperation worldwide.
COST supports mobility of researchers to create a scientific network and
stimulate innovative activities

LIFE CYCLE ENVIRONMENTALASSESSMENT ( LCA )
Process to valuate the environmental burdens
associated with a product process or activity by
identifying energy and materials used and wastes
released to the environment, and to evaluate and
implement opportunities to affect environmental
improvement

To identify energy and materials used and wastes released to the environment, and to
evaluate and implement opportunities to affect environmental improvement.OBJECTIVES

LIFE CYCLE COSTING( LCC )
ISO 15686-5: 2008
Calculation methodology concerned with the
estimation of the costs, in monetary terms, overthe whole life cycle : construction, operation,
maintenance and repair (and sometimes
demolition) of a building.
Minimising the sum of the life cycle costs, in current values, thus benefiting both owner and
end users. LCC aims at the optimization of the design granting better results in extended life,performance and sustainability, avoiding over design and excessive waste.
OBJECTIVES
BENEFITS
Compared to the current approach, which estimates only the direct costs for construction and
maintenance, LCC extends the analysis over the whole life of the project , showing the real
value of the investment.

WG3 attempted to provide an overview of the degradations models developed in

Deterioration models of structural materials are usually expressed as dose-response
functions which provide the deterioration rate of a given material over time as a
function of both material related factors and structure environment parameters.

Catastrophic events & Resilient urban environments
Constructions are subjected more and more to exceptional
actions, which were not taken into account at the design stage,
producing huge damages.
In line with that a growing attention has been put towards the
concept of resilience of urban environments. With the aim to
reduce both the produced damages and the repair time.
but resilience & Sustainability are related. Many of theessential principles of sustainability are strictly linked to the core
pillars of resilience. The next step is to take a step forward and
talk about sustainable resilience
