4.3 The challenges
The result of the challenges ranging between (strongly agree) and (moderately agree) .62% of the
total choices are (strongly agree) that in developing countries the lack of sustainability knowledge lead to the absence of sustainable design.49% of the total participants (strongly agree) that
the initial cost of sustainability might turn people away from it without consider the saving during the project’s operating, while 38% (moderately agree)
Meanwhile, 34% of the total choices (strongly agree) with the lack of skilled professionals lead to
reduce the sustainability practices while 24% (moderately agree). 9% (strongly agree) about the
rapid rhythm of constructions in U.A.E minimize the ability of evaluated the building performance
.24% (strongly agree) and 23% (strongly disagree) that the lifestyle of U.A.E limited the ability of
used recycling or reused materials, 20% (strongly agree) 43% (moderately agree) about the preferring the profit from the building rather that the building performance. 48% (strongly agree)
and 42% (moderately agree) about the significant important of public involvement in sustainable
projects in order to create sense of responsibility towards their environment. 20% (strongly agree)
and 43% (moderately agree) about the lack of local manufactured materials in the market reduces
the use of materials that suitable for U.A.E climate. 29% (strongly agree) while 38% (moderately
agree) about the missing data from the monitoring and reporting for occupied buildings lead
to absence of rating system for constructions in U.A.E .According to the result above, it’s very
clear that most of the participants recognize the challenges and considered the constraints which
facing the sustainability achievement. This awareness about the obstacles can be accounted as
advantage because the first step in finding solutions is to recognize the problems first. It seems
that the next period of time will witness many improvements in adopting sustainability as a consequence of the knowledge improvements.
4.4 The impact on the sustainability and performance of building
The efficient design is the main component to measure sustainability, while energy used, population growth, resources efficiency and the waste are the others components. The improved in
building performance leads automatically to achieve sustainability. The failure in building performance will lead to change the direction away from the sustainability achievement. One of the
important factor to increase the ability of improving building performance is the site analysis
whether by software analysis or by simulation methods to recognize the best orientation and
how can be used to reduce energy or harness the site conditions to provide energy for instance
the use of solar panels or photovoltaic in order to reduce energy consumption .It shows from
the survey that 52% of the vote going to sometime while 5% choose never and 33% choose almost always as shown in Figure 6 normally this will affect the building performance in terms of
ignore the indoor air quality which depend on natural ventilation. In the other hand it affects
the achievement of sustainability by increasing the energy consumption and used of electricity
though the cooling system.
