Abstract

Dampness in properties has been a long-standing problem since Victorian times and although it is more prevalent in older properties, it still poses a relevant threat to modern buildings. Dampness in buildings is a major problem with serious implications for both the fabric of the building and the health of its occupants. The aim of this study is to provide practical recommendations for preventing and solving the problem of dampness in buildings in order to improve the safety and health of buildings, extend their service life and promote sustainable development. The objectives of the study are to identify the factors affecting the occurrence of dampness in buildings, to investigate the effects of dampness, and to propose solutions to prevent dampness in buildings. There are many factors that contribute to building dampness, such as poor building quality, water leakage, inadequate ventilation and excessive humidity. Dampness in buildings can lead to various health problems, such as respiratory problems and allergic reactions, and can also cause damage to the building structure. Therefore, it is important to understand the causes and effects of building dampness and to identify effective ways to prevent this problem. In this study, simple random sampling was chosen and questionnaires were distributed to the residents living in Klang Valley and a total of 394 respondents responded to the questionnaire. The results of the questionnaire were analysed through Cronbach's alpha analysis, descriptive analysis and cross-tabulation analysis. Most of the respondents strongly agreed with the questions in the questionnaire. This shows that most of the respondents living in the Klang Valley have faced dampness problems and they are aware of the factors, effects and solutions to prevent dampness.
