Prihatmanti, R and Bahauddin, A (2014) Indoor air quality in adaptively reused heritage buildings at a UNESCO world heritage site, Penang, Malaysia. Journal of Construction in Developing Countries, 19(1), pp. 69-91. ISSN 1823-6499
Abstract
This study investigated the Indoor Air Quality (IAQ) level in heritage buildings that have been adaptively reused as office buildings. These buildings are located within the vicinity of the UNESCO World Heritage Site in George Town, Penang. The aim of this study was to determine the IAQ level in the designated buildings using thermal monitoring and chemical and microbial tests. Mixed methods were used in this cross-sectional study to achieve the objectives. The IAQ tests variables were the temperature, relative humidity, air velocity, airborne pollutants (Particle Matter 10 [PM10], carbon monoxide, carbon dioxide and formaldehyde), total bacteria count and total fungal count. These variables were adopted from the Industry Code of Practice on Indoor Air Quality, Department of Occupational Health Malaysia and the Malaysian Green Building Index-Non Residential Existing Building (NREB) rating tool. The measurements show that the IAQ level in the identified buildings was unacceptable within the standards stipulated. Dampness stains and mould were present in all buildings due to high humidity and moisture levels. It can be concluded that the IAQ level was due to inappropriate adaptive reuse practices, the occupants' activities and maintenance irregularities.

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
