Interiors' users feel more satisfied and content in healthy environments that respond to their individual preferences and needs. Therefore, occupants' satisfaction in an interior space is the target goal of any interior designer. Many studies focus on and investigate users' satisfaction with indoor environmental quality, including thermal, visual, and acoustic qualities. The indoor environmental factors involve more than these subjective characteristics. According to the Well Building Institute, the seven contextual concepts of a healthy interior should care about the air, the water, the nourishment, the fitness, the light, the comfort, and the mind of its users. Indoor environmental design factors should include more contextual criteria. The topic leads to the factors affecting people's satisfaction being standardized based on the type of interiors. Educational spaces have specific regulations, but once the place is a college of design, the criteria are more complex to discuss and apply since the end users are designers.

The paper's main point is to explore the environmental design factors that lead to the occupant's satisfaction within the colleges' interiors, especially in the design and art colleges. The occupants, in this case are the future designers and artists – the students – and the professionals in the field – the instructors of architecture, interior design, and art fields. Their cultural background – their cognitive responses – affects their perceptions and preferences, making them notice different things and appreciate different things, making it almost impossible to satisfy designers.

The paper methodology will follow a theoretical, analytical approach to reach the guidelines outcomes for reaching a satisfactory interior layout. Analyzing the Well Institute's seven concepts and exploring the psychological effects on users based on these concepts will permit an appropriate background to the study. These criteria are the air, the light, and comfort, directly related to the interior design elements, and they have physical and psychological facets. The map between physical and psychological aspects is part of the theoretical study to reach study design guidelines. It is crucial to design interior spaces that care about the human and teach our future designers to follow developed guidelines.

These studies enable interior designers and educators to have basic grounded guidelines and help apply their designs according to the users' preferences. Cultural context is a criterion to be added following the case, and the design problem for a specific project's location is selected, then the design development follows these concepts. As life gets complex, it is crucial to get updated guidelines and improve them and simplify these guidelines to achieve more successful interior designs that respond to its users' needs. Such guidelines are the essential tools to develop the educational sector in an interior design program.
