Applicability of Assessment Indices for Hanok-User Sensory Comfort Based on Visual and Tactile Comfort Evaluation Indicators

Abstract

This study aimed to present an evaluation system to assess comfort that reflects the unique value of vernacular architecture. For this purpose, the background, purpose, evaluation items, and evaluation methods of Korean Standard-Basic Part: 6300-1, 2 (KS A 6300) were analyzed. As a result, the weakness was found in the KS system that there was no method to evaluate the user’s human sensory comfort. To overcome this problem, the contents of KS A 6300-1, 2 were analyzed, and evaluation indices were categorized to assess the comfort of human sensory experience. A comfort assessment index was then derived to evaluate the visual and tactile comfort of the Korean traditional house by analyzing previous research and systems. To assess the possibility of using the Hanok evaluation system for the derived comfort indices, the actual building environmental and user data were collected for one year. Based on the previous step, Predicted Mean Vote (PMV) and Daylight Glare Probability (DGP) were calculated, and at the same time, a comparative analysis was conducted with the collected user data. As a result, DGP showed a tendency of changing user comfort and an error of 7 to 8% regardless of region, while PMV showed a tendency similar to the change in user discomfort response rate. Accordingly, it was concluded that each evaluation index could be used for the comfort evaluation of Hanok.

Utilization of the Evaluation System for Spatial Comfort toward Multi-Layered Public Hanok Facilities

“…Choe and Han also insisted, in a paper titled 'Applicability of Assessment Indices for Hanok-User Sensory Comfort Based on Visual and Tactile Comfort Evaluation Indicators', that a combined PMV and daylight glare probability (DGP) would be applicable to fix the limitations caused from irregular human environment especially with the sensory factors in a comprehensive thermal and daylighting conditions. This means that an individual comfort factor like PMV would be widely challenged due to its inaccuracy, and a qualitative method like a field survey from people could adjust the problem as suggested by Korean Standard (KS) 6300-1, Examination method for Hanok-Part 1: Comfort [19]. Therefore, it would be necessary to compare the calculation results from the standard and the actual sensations of users and/or residents in target spaces.…”
