Principles and Strategies of Daylighting in Office Buildings

Most of the offices in the world are in operation all day. They usually start working at 7 AM and end at 4 AM or 5 AM. Daylight is an essential resource for everyone to use - and may be used in the near future. It also has very special features that change the interior space from a boring uniformity to a vibrant and pleasant experience. Being able to brighten up and make it attractive is one of the main reasons architects try to incorporate sunlight into buildings wherever possible.

Because business hours are mainly during the daytime hours, there is a big advantage in maximizing the use of sunlight in office buildings. The main difficulty in achieving this goal is a nonuniform distribution of sunlight levels. As the depth of the room grows farther away from the window, my brightness dramatically drops, the backside of the office gets less bright and the front of the office near the window becomes very bright and glare. Nikkyo is a medium in which human eyes adapt biologically. Although the artificial lighting used in the office occupies 50% of the primary energy consumption, due to the close relationship between the opening hours and the availability during the day, when using it according to the outdoor lighting level, the effective use of sunlight will increase from 35% It will be reduced by 75%. The proportion of the amount of lighting power consumed by the control that automatically dims the lighting

Before the 1950s, sunlight was the main light source of the interior lighting of the building. Building planning and architectural shapes are designed to make the most of sunlight, for example.

Considering environmental and cost reduction problems, windows and lighting have been considered in various ways in the history of architectural design. Daylight lighting has been used for the main purpose of lighting since it is estimated that 30 to 50% of the energy cost of office buildings will be used for lighting to achieve energy efficiency.

Sustainable development in the 21st century For example, lighting and ventilation strategies have been consciously considered in architectural design, regardless of cheap artificial lighting and HVAC systems for centuries. The difficulty of updating these buildings to the required standard of living and sustainability is causing problems here. And you will not be able to continue making such design choices. Whether we update the building of the century built in the 20th century or the renewal of the architecture of the 20th century, our lesson is the same. As demand is unknown or even unknown, does the building built today have the longest useful life?
