Inomhusmiljöproblem i fuktiga byggnader : En utredning av åtgärder vid fuktrelaterade inomhusmiljöproblem
Dampness in the indoor environment have been a major issue of discussion the last decades since more and more people complain about their indoor environment. In the present situation there are difficulties to find what causes people’s discomfort in a damp environment even though there is a strong connection between dampness and human health.
The aim of the thesis was to contribute to the work done today to achieve a better indoor environment in damp buildings. The purpose of the work was to evaluate whether the measures issued for dampness in the indoor environment contributes to the improvement of health and environment for those who are living or working in that space. Through a literature review, interview and survey the following three questions were answered to achieve the aim and purpose:
- How are people affected by the indoor environment in damp buildings?
- Which are the measures issued to prevent dampness in the indoor environment?
- Do these interventions contribute to a better indoor environment?
How people are affected by the indoor environment in damp buildings and how these problems are prevented were the foundation for the continued work with the survey. The discomforts that are often related to dampness and mould are respiratory symptoms and asthma. In addition symptoms such as fatigue, headaches, nausea and reduced lung capacity are also connected to these problems. The measures that are recommended in prevalence of dampness and mould growth have either the intention to prevent dampness and mould growth in buildings or remove unpleasant odour from the indoor environment. The measures used are cleaning, dehumidification, underpressure, improved ventilation and deconstruction and reconstruction.
Furthermore, a survey was conducted where 9 different projects participated where the employees experienced these problems. The result was then divided in two groups where they either had implemented all the measures proposed by specialists or had only implemented some of them.
The result of the survey showed that the applied measures contributed to the improvement of the employees health since less people felt the symptoms such as irritation of eyes, nose or throat, dryness of the throat or skin and fatigue, headache or nausea. It was especially noticeable for those who were working at a project were all the measures had been implemented.
Recommendations for future investigations in the subject are to study how different measures improve different health problem. Even though the measures appliance are known it is still unknown how they are related to different health problems.
