“…The symbiosis between the microalgae culture system and the building can also be beneficial for medical purposes [21], human food [22] and animal feed production [23], wastewater treatment [24,25], and production of bio-products [26] as well as energy [27]. Yet, there have been few attempts to integrate algae bioreactors into building envelopes as a kind of green façades [28] for thermal regulation [29], despite there are numerous researches on green building envelopes in terms of thermal and energy performance [30][31][32][33]. Besides, this technology is still in its infancy stages [8] in both research and development, and numerous challenges remain to be addressed before the wider application of this technology.…”

“…In this study, horizontal windows in the central position have the lowest energy consumption compared with the square windows in the central position. This was proved in a similar study [59]. Another study showed that continuous horizontal windows on the west and east orientations are better than separate horizontal or other types of windows [60].…”

Nowadays, the use of renewable energies has increased due to the energy crisis and subsequent environmental issues. The window design significantly affects energy consumption and natural light absorption regarding preventing visual discomfort and improving indoor quality with effective external features. Hence, it should be carefully selected from the early stages of design. Thus, the present study investigated the optimal design of windows considering four components of the window-to-wall ratio (WWR), window shape, and positioning on each façade by separately considering the sill height of the window for a general office. The objective was to provide visual comfort and save energy. Applying constraints to the data set can yield an optimization method concerning the variables and their relationship as well as optimal solutions based on the stated goals. Therefore, the desired groups can be accepted as optimal solutions for improving the efficiency of the building. According to the results, the WWR of 30% with the square and horizontal shapes in the upper and central positions were optimal solutions for each window orientation, which had better performance in the north-facing WWR of 40%. Furthermore, several best design solutions were presented in each orientation in terms of energy consumption, daylighting, and visual comfort in the indoor environment. This method also allows the designer to visualize all the data while finding the clients’ desired option by improving the energy efficiency between the variables and choosing the appropriate solution.

“…In a study on the westand east-facing rooms, continuous horizontal windows performed better than other types of windows and separate windows with the same glazing ratio in a temperate-dry climate [47]. Similar studies show the benefit of windows that are stretched horizontally [48]. Horizontal windows are also considered effective in improving circadian rhythms [8].…”

This study aims to determine the optimum size of windows based on the window-to-floor ratio (WFR) for the main cardinal directions in Hot-summer Mediterranean (Csa) and Dry Summer Continental (Dsa) climates (Köppen–Geiger classification system) by carrying out a multi-objective optimization that relies on three dynamic metrics of Useful Daylight Illuminance (UDI-a (autonomous)), Daylight Autonomy (DA), and Annual Sunlight Exposure (ASE1000,250) in Radiance version 5.1. A validation against field measurements is conducted under an overcast sky with an illuminance of 11000 lux. The Pareto front is used to pick the best solutions for evaluating the most optimized solutions. Accordingly, the minimum standards for cardinal directions in each climate are defined. The minimum suggested WFR for the Dsa and Csa climates for the south-, east-, north-, and west-facing windows are 20%, 15%, 20%, and 15% (Dsa) and 20%, 20%, 25%, and 20% (Csa), respectively. Furthermore, the results show the shape and relative proportions of windows (vertical/horizontal) have a significant effect on the metrics. As a result, this paper introduces the “Proportion Ratio” as a new indicator for designing windows.
