Methods of Statistical Analysis in Social Research as Criteria for Assessing Visual Comfort of the Architectural Environment in Green Standards

Contemporary architectural theory and practice increasingly acknowledge that true sustainability extends beyond quantifiable metrics of energy efficiency and material science. A singular focus on purely engineering aspects often leads to the neglect of the human factor, particularly the visual and aesthetic qualities of a building and their profound impact on occupant health, productivity, and overall well-being. This creates a significant methodological gap, as existing green building certification systems like BREEAM, LEED, WELL, DGNB, Green Globes, CASBEE, HQE, and Minergie, while leading in their field, are predominantly focused on quantitative measurements. They demonstrate a certain deficiency, or complete absence, in the consideration of aesthetic criteria, which in turn questions the comprehensiveness of their assessments. This necessitates the development of a methodology capable of integrating the subjective perception of aesthetics into an objective system of green certification. This article, as a part of a comprehensive dissertation on the topic, is focused on analyzing current practices within these leading green standards. The primary goal is to substantiate that surveys, public involvement, and statistical methods can form a reliable foundation for creating an objective assessment methodology. While some standards recognize the importance of engaging stakeholders, their application is often fragmented and insufficient for a holistic aesthetic evaluation. For instance, the LEED v4.1 prerequisite "Integrative Planning and Design" for healthcare facilities mandates the involvement of a wide array of specialists, yet these measures do not form a unified mechanism for aesthetic evaluation. The clear methodology proposed here will bridge the gap between subjective perception and objective criteria. The use of user surveys at various project stages, from initial design to post-occupancy evaluation, provides a key tool for data collection. These data, upon statistical processing, become objective indicators of resident satisfaction and comfort, transforming emotional and visual reactions into a quantifiable expression. The relevance of this research is underscored by the need to prove that these methods are not merely a supplement but a vital path to objectivizing subjective perception. Without such an approach, the assessment of aesthetic qualities will always remain a matter of individual opinion and potential manipulation. The findings from this analysis, which examined eight green standards and found a total of 15 criteria across six of them, with none found in HQE and Minergie, confirm the existing methodological deficit. This research serves to argue for the role of these tools as a fundamental element in the methodology for assessing the aesthetic qualities of a project. The ultimate goal of this research is to create a criterion for aesthetic properties that will be incorporated into a future national green rating system.
