The purpose of this study was to apply health performance indicators to actual apartments in order to evaluate the health performance of high-rise and highdensity Korean apartments and their environment. In addition, this study analysed factors that are perceived as affecting the residents' satisfaction. To this end, two apartment complexes that are in a similar location and environment, but with a 10-year difference in their age, were examined and evaluated. Both apartment complexes were assessed as healthy in all dimensions, but unhealthy in the attribute of information management in the managerial dimension. The study also identified that residents were positive and enthusiastic about the performance evaluation. Both groups of residents responded positively and showed satisfaction with their housing environment with no significant differences between the two groups. However, using different evaluation dimensions and attributes could affect their observed satisfaction levels based on residence duration. Therefore, in order for these apartments to be recorded as healthy environments, evaluation indicators would need to be validated and illustrate a healthy housing quality, which reflects the characteristics and current status. The evaluation results can then be utilised to develop guidelines to manage and maintain healthy housing environments for apartments.
This study evaluates the health performance of high-density, high-rise public housing in Korea to seek ways to improve their performance for the health and wellbeing of occupants. To do this, the existing 'Health Performance Indicator for the Public Housing' developed by a previous study in 2010 was utilized to compare and analyse the characteristic differences as evaluated by experts and the residents. The survey tool was developed to allow evaluation by the experts using pairwise comparison between components; while the residents were asked to evaluate the relative importance of the components in the survey tool. Furthermore, Analytic Hierarchy Process was applied to the evaluation given by experts and PASW statistical package was used to analyse the survey results given by the residents. The results showed that the residents do have a high awareness of the impacts of the various components in their apartments that could be seen visually, revealing a partial difference in their awareness in comparison to that given by the experts. It is therefore necessary to utilize this understanding of the experts and residents in order to meet the actual demands of the residents in accordance with their awareness. It is expected that the evaluation results of this study would be used in the construction plan of new apartments to promote healthy housing and to incorporate not just the experts' view but also the demand of the residents.Furthermore, a series of studies have been conducted with a focus on evaluation of the physical performance such as environmental factors (e.g. thermal, noise, air) and indoor pollution as well as
Summary
Knowledge about the heat release rate (HRR) is essential for studying tunnel fires. The standard method in ISO 9705 is widely applied to calculate the HRR of combustion by measuring the consumption of oxygen in a fire. However, the studies of HRR measurement in full‐scale tunnel fires are rare because of the complication and costs of large experiments. This paper presents a system based on the principle of oxygen consumption calorimetry for the measurement of HRR and total heat release (THR) of full‐scale fires in tunnels. A total of 22 fire experiments are performed in a large‐scale ventilated testing metro tunnel with dimension of 100.0 m × 5.5 m × 5.5 m to validate the reliability and effectiveness of this system. Firstly, four oil spray fire tests are conducted with nozzle flow of 106 L/h at (1 ± 0.1) MW HRR to calibrate the instrumentation. Then, 18 full‐scale fire tests using square diesel pools at five sizes (0.5, 1.0, 2.5, and 5.0 m2) and wood cribs as fire sources are carried out for the measurement of HRR and THR. Results provided by the comparison between the measured HRR and THR values of the fire tests and the theoretically calculated ones show that our system works effectively in the HRR measurement of full‐scale fires in tunnels.
