Abstract
:1. Introduction
2. Materials and Methods
2.1. Criteria forEevaluating the Quality of Housing
2.2. Evaluation of the Comfort Performance of Hanok
- Absolute Humidity Difference= 0.33 − 0.239 × Summer Season Survey Average Score (p-value < 0.001)
- Absolute Humidity Difference= 1.128 − 1.215 × Survey Average Score (p-value < 0.001)
- Thermal Resistance Satisfaction Rate by Region (%)= 69.7 + 2.154 × Survey Average Score (p-value < 0.001)
2.3. Questionnaire Composition
- Short and concise questions;
- Avoiding the use of academic jargon or difficult words;
- Avoiding duplicate responses;
- Preventing respondents from being bored;
- Arranging questions logically and probably;
- Intuitive response induction;
- Quantification of data that could be used statistically.
