selecting a proper daylighting system can help minimize artificial lighting, control energy consumption and,
consequently downsize air-conditioning systems. This issue becomes more critical when building facades are mainly
glazed. In fully glazed facade, daylighting systems perform sufficiently enough in terms of solar protection, daylighting
harvesting, and interior heat gain. Simultaneously, they can block the daylight entity, cause the need for artificial light
and prevent the winter solar radiation. Increasing the number of influential factors in louvre design will complicate
their design processes. Louvres are made up of numerous horizontal, vertical or sloping slats. Louvre properties with
complex features and several parameters, such as tilt angle and solar angle of incidence rotation angle, shape, size,
configuration, and color of slats, all impact glare and visibility and build energy efficiency Not only several parameters
of the louvre device but also the variety of analyzing factors such as energy performance and visual comfort affect the
design process. Overlooking each setting has a significant effect on optimization results. Due to this complexity, most
research in this domain narrowed to a limited range of variables. Besides, since the focus of most research in this field
has been on multi optimization, the final step of them has been the attainment of optimizing results. Optimization is
the procedure of finding the minimum or maximum value of a function by choosing a number of variables subject to
a number of constraints. The optimization function is called cost or fitness or objective function and is usually
calculated using simulation tools Yet, the further level, which is proposing proper design alternatives for each climate,
has been neglected. This research not only proposed a workflow to optimize building louvres by considering the most
promising influential factors but also proposed design alternatives in understudied climate zones. These alternatives
will be proposed by categorizing the results form Pareto Front GA optimization. We will come up with specific louvre
features which compatible with a specific climate. These design alternatives assessed by energy performance, visual
and thermal comfort in the mentioned climates. The research will be carried on by a mixed-method research
approach. We will evaluate energy, visual, and thermal comfort based on the quantitative methods, and then try to
categorize obtained cases by climate based on the quantitative method. To do that, Firstly, we define variable
parameters of louvre forms and their position on building façades. Secondly, we set three different climate zones
based on the Koppen classification. We will analyze energy performance, thermal and visual comfort of incorporating
louvres in these climates. Thirdly, since several possible solutions will be gained, we employ Pareto chart to reach
optimized outcomes. Furthermore, Finally, based on the achieved design alternative, we will use qualitative research
on categorizing results in each climate zone. The results show significant change between louver parameters in Bandar
