Natural lighting in commercial interior space & techniques for using it as a sustainable element.

​Abstract:  Space lighting aims to adequately illuminate visual tasks, create an attractive visual environment, and save electrical energy, as the building design scheme and application of systems all play roles in achieving these goals. The performance of the daylight strategy for the space depends on the availability of daylight on the building envelope which determines the potential for daylighting in the space (the physical and geometric properties of a window and how it is used to exploit and respond to available daylight; the physical and geometric properties of space).

Passive solar strategies use building components to collect, store, distribute and control solar heat gain. It includes the implementation of large windows facing the south, the provision of building materials that absorb and release heat slowly, the treatment of the shape of the building to affect ventilation, and the reduction of unwanted heat gain through the appropriate selection of windows and glazing, or the use of shading devices such as roof columns or landscaping, to reduce the solar load.

The use of natural light does not only include the use of positive effects or direct use of lighting and heating, but rather the focus is on effective responses to its negative effects. In the specific design process, the pros and cons are weighed according to cross-cutting factors such as the nature of the building, function, environment and economy. This is because natural light is an issue that must be paid attention to, and it is wrong to copy other forms of buildings in architecture and design even if they are successful.

Many buildings designed in hot climates in recent years use shading to take advantage of solar energy rather than direct daylight; Reducing cooling loads was the driving force in these designs. Solar shading glass was used to exclude solar radiation, and the function of the window was limited to providing a view outside; The transparency of daylighting systems is a major issue, and building materials for a daylighting system need not necessarily be transparent in themselves in order to provide an outside view; The subjective impression of visual contact outside is most important, as the function of an anti-glare system inevitably affects visibility outside, and both sun shading and daylight redirection affect the view as well.

Interior design can get very wasteful in commercial areas. These places/spaces require preserving the place's image and importance, and clarifying the idea that it is trending, up-to-date and advanced when compared to competing buildings. And with updated themes comes a high turnover of waste.
