Technology is the ultimate component for
more sustainable buildings and better quality of life.
Technology also changes our lifestyle and habits.
Retrofitting of old buildings transform the spaces we live
in; from a simple mixture from various construction
materials to sophisticated high- performance machines
thanks to the development and advancement in
technology. One of the research domains for retrofitting
is the building envelope and building facades as a subset
of it. Increasing awareness towards energy conservation
and reducing carbon emissions requires finding
appropriate technological solutions in terms of facades
which is a mediator for the ecological among external and.
This energy conservation performance of the building can
be drastically improved by contemporary façade
technologies. Various design strategies are available for
better façade performance which includes developments
in the field of smart materials, better thermal insulation,
power generation, vertical gardens and green
infrastructure, selecting optimum mixture of solid and
void areas, dynamic shading elements, biomimetic design
approaches, light shelves, etc. The impact of the external
environment is reduced by using static and mobile
systems with great savings for energy expenses as well, A
façade is providing appropriate natural ventilation,
shading, and openings in hot locations. Meanwhile, It also
allows the sun to shine as brightly as possible in colder
climates. This adjustment ensures a perfect environment;
The term "intelligent" facades refers to facades that
change their aesthetic appearance.
Three elements can be used to classify the
comprehensive performances of intelligent façade device,
energy consumption, visual comfort, and thermally
comfort are the three key system utilities.
Each of these utilities is defined as a function of the
system's can be observed situation while adhering to a set
of extra control variable requirements, The summation of
these three utilities evaluated by user preferences is then
used to create the cost function.
The restricted nonlinear optimization problem
arises when the cost function is minimized. The system's
dynamics are highly nonlinear, and there are extra
constraints on the control variables, Analytically solving
this optimal control problem is tough. On the contrary,
daylighting is frequently used to save electricity and may
also improve visibility, The primary benefits of
daylighting are untouchable the use of natural light in
construction is influenced by a number of variables. These
variables ae summarized in aesthetics, psychological
response, health, energy and cost.
In this research the detailing principles and the
identification measures for smart facades a well as their
main effects on office buildings, with reference to previous
case studies and past projects located mainly in Saudi
Arabia are elaborated.
