It is possible to find various definitions of sustainability in different disciplines, such as sustainable economy and sustainable agriculture. Sustainability in design is handled a little differently from these general concepts; it needs to be interpreted outside of the usual definitions. The aim of this study was to consider sustainability, which has a popular place in today's design concept, within the scope of the design of office interiors and to interpret its effect on the design of these spaces. The concept of sustainability, which we can interpret as a tangible effect of the Industrial Revolution, has caused mankind to face the fact that the necessary resources are not infinite, regardless of space or product design. Developing technologies have made migration from rural areas to cities attractive. This situation also caused unconscious consumption of energy resources and made mankind question the production and consumption process again. Especially in new building systems, energy conservation and minimizing environmental pollution through sustainable design approaches come into play at this point, allowing the user to reach comfort conditions of the living space. The main function of offices is to continue the act of working and doing business. However, the concept of office, which developed over time, has allowed additional functions to be added to these office areas, with working areas, resting, socializing, eating areas etc. The office has turned into places where needs are also met. With changing conditions, office interior designs must also adapt to these conditions. It is important for office interiors to be sustainable, to adapt to changing conditions and to meet more demands with differing function needs. Within the scope of the study, control systems that create physical environmental conditions such as heating, ventilation, lighting in office interiors and criteria that can make the space sustainable such as flexible furniture, correct space organization, selection of materials and reinforcement elements will be discussed in detail. Technologically equipped applications required to create sustainable office interiors will be explained through selected examples.
