for selecting the final scenario. This interactive approach brings together expert
intuition and rational systematic verification (Flourentzou and Roulet

As one can see, the above-mentioned research has enabled the authors to solve a
majority of problems in a complex way as far as energy-efficient built environ-
ment's MCDM is concerned. However, one of the weakest aspects of the above
research was the formation and multiple-criteria analysis of alternative variants of
the whole energy-efficient built environment. The authors of this chapter have
developed
methods
of
multi-variant
design
and
multiple-criteria

of
energy-efficient built environment to tackle these problems.
3 Model for a Complex Analysis of Life Cycle
of Energy-Efficient Built Environment
In order to develop a high-quality built environment, it is necessary to take care of
its efficiency from the brief to the end of service life. The entire process must be
planned and executed with consideration of goals aspired by participating stake-
holders and micro-, meso- and macro-level environment. In order to realize the
above purposes, an original model of a complex analysis of life cycle of energy-
efficient built environment (see Fig.
3
) was developed enabling to analyse life
cycle of energy-efficient built environment, the parties involved as well as its
micro- and macro-environment as one complete entity.
A model was being developed step by step as follows (see Fig.
3
): a compre-
hensive quantitative and conceptual description of a research object; multi-variant
design of life cycle of energy-efficient built environment; multiple-criteria analysis
of life cycle of energy-efficient built environment; selection of the most rational
version of life cycle of energy-efficient built environment; and development of
rational micro-, meso- and macro-level environment. The above model will be
now described in more detail.
For more comprehensive study of a research object and methods and ways of its
assessment, major constituent parts of the above object will be briefly analysed.
They are as follows: life cycle of energy-efficient built environment, the parties
involved and micro- and macro-environment having a particular impact on it.
Life cycle of energy-efficient built environment in turn consists of seven closely
interrelated stages, such as brief, design, construction, maintenance, facilities
management, demolition and utilization.
At the stage of brief, the stakeholders state major requirements and limitations
regarding the energy-efficient built environment in question.
Energy-efficient built environment is being designed with account of the
stakeholders' needs as well as the possibilities of designers, constructors, suppli-
ers, facilities managers, etc. At the design stage, life cycle of energy-efficient built
environment multi-variant design and multiple-criteria analysis should be carried
out taking into account the experience gained in realizing similar projects and
