Abstract
Problem related with indoor air quality (IAQ), is rapidly becoming a major health issue as people spend almost 90% of their time indoors. Museums were established in Malaysia more than hundred years ago. Since the year 2005, Malaysia has been moving away from constructing new buildings in favour of refurbishing historic and old ones. A healthy environment at the museum building has been identified as one of the important element that must been considered, but it is not sure either IAQ in the museum building provide a good air quality or not. The purpose of this study is to determine the actual indoor environment of the museum building in Melaka. In this study, the IAQ measurement were conduct for six days at the Melaka Sultanate Palace Museum and at the History and Ethnography Museum. During the measurement, IAQ parameters of gaseous pollutant of nitrogen dioxide, sulfur dioxide and carbon dioxide, and particulate matter of fine particles were recorded by using specific IAQ equipment. The finding of this study indicates that the distance of buildings from roadways appears to have an impact on indoor environmental levels, especially for nitrogen dioxide, sulfur dioxide and particulate matter. Based on the results, only gaseous pollutant of sulfur dioxide had not exceeding the acceptable TLV compared to the other IAQ pollutants.
Highlights
Air is the most important element that supports human life on earth [1]
Case Study 1 and Case Study 2 are located at urban area and based on Figure 6, it shown that NO2 concentration for Case Study 2 are higher and more pollute compared to indoor levels of NO2 for Case Study 1, because there was heavy traffic occurred, especially on weekends (Day 1, Day 2 and Day 3)
In Melaka, tourism is a popular destination among tourist and as a state which is associated with history, museum such as the Melaka Sultanate Palace Museum and the History and Ethnography Museum are among the most popular museums that received quite a huge number of visitors annually [35]. It shown that CO2 concentration for Case Study 1 are higher and more pollute compared to indoor levels of CO2 for Case Study 2, because Case Study 1 received higher visitors compared to Case Study 2
Summary
Air is the most important element that supports human life on earth [1]. For an example, in breathing people need to inhale air, especially clean air in order to live a better life. Problem related with indoor air quality (IAQ) is rapidly becoming a major health issue as people spend almost 90% of their time indoors, which they might be exposed to hazardous and unhealthy concentrations of pollutants due to the improper air circulation turnover within and outside the building [4]. Aged, ill people and youngsters who spend longer time inside the buildings have a tendency exposure of indoor hazardous pollution. These indoor environments are including homes, offices, stores, restaurants, warehouses, factories, public buildings and vehicles. In these environments, people are exposed to pollutants emanating from a wide array of sources that creates indoor environmental problems which could affect their health
