Defining the Color Weight of Residential Building Façade, Using Q-Factor Analysis

Designing the facade's color based on user evaluation is necessary due to the effect of color on people's evaluation. To evaluate the facade's color, its combination should be categorized. The emotional dimensions of color evaluation should be assessed due to the variety of emotional scales of color evaluation. Thus, the question arises: What are the emotional scales describing the facade's color and components. During a study, temperature, harmony, and weight were considered to describe the color in facades. This study used a combination of qualitative and quantitative methods to examine the components related to defining the color composition's weight scale. First, some components were identified to determine the weight of the color combination through a semi-structured interview. Based on the results, a questionnaire was prepared. The final results were obtained using the Q method analysis with the help of color strips and HSL codes. Therefore, to describe the combination color of the facade as light and heavy, the facade with a light color combination has at least ۳۰% openings. At least ۷۰% of facade areas and openings have a hue with more than ۹۰% lightness. In addition, the saturation of at least ۷۰% of the area is less than ۳۰% and ۵% with warm and cool hues, respectively. At least ۷۰% of facade areas and openings have a hue with less than ۶۵% lightness and a heavy color combination.
