Abstract
Purpose: During the COVID-19 pandemic in 2020–2021 in Indonesia, the indoor environmental quality (IEQ) of local houses occupied by infected occupants was adversely affected. This paper aims to appraise the IEQ of the affected Banda Aceh houses with insights into enabling them to be resilient against the negative impacts of the pandemic. Design/methodology/approach: Quantitative field measurement in the case study of five concrete houses located in urban areas which are affected by IEQ factors: (1) indoor air quality (IAQ), (2) thermal comfort and (3) visual comfort, compared against the Indonesian National standard (SNI). The case study involved measurement of the first two factors over 24 h, while the third factor was measured during sun hours. Considering the limitations of the measuring tools for logging available data in this research, air quality is measured from 8 am to 10 pm. Findings: Thermal comfort in the affected houses is generally regarded as warm, optimal and cool comfort, indicated by the effective temperatures of between 20.5 and 27.1°C. Frequently closed windows, limited land area and access had caused a lack of air circulation, with air velocity of dominantly 0 m/s in the houses. The illuminance of natural light received in three houses was insufficient – less than 120 lux as compared with the other two. This study found an uptrend of higher air temperature and relative humidity in the affected houses resulting in poorer IAQ; conversely, the higher the air velocity in the houses, the fewer the indoor air pollutants such as formaldehyde (HCHO), total volatile organic compounds (TVOC) and carbon dioxide (CO2). Originality/value: This study is a pioneer in evaluating IEQ in houses occupied by COVID-19 patients in Indonesia, especially in dwelling cases in Aceh Province. It also encompasses environmental and societal challenges to sustaining resilient buildings in pandemic hit regions.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
