This report reviews research into the release of volatile organic compounds (VOCs) from paints and coatings from two perspectives: (a) drying and film formation, and (b) voc emission into indoor air. The former has been investigated by the paint industry for some decades, especially in relation to understanding drying mechanisms to assist product formulation and development. The latter is of more recent interest and is directed to predicting and controlling the impact of VOC emissions from paints and coatings on indoor air quality.

This materials odour emission project was conducted for the Task Force on Materials Emissions and four industry sponsors. The objectives of the project were to review material odour test methods, conduct comparative tests of various materials by the most applicable methods and to recommend test methods for materials odour emission characterization. The review identified six test methods which were then compared in a program of odour testing of 1 0 materials. Two test methods were quantitative odour intensity methods and four methods used perceived intensity and hedonic scales.

Heating ventilating and air conditioning (HV AC) duct insulation in a county government facility in south Florida USA was removed because of heavy fungal infestation of the building. Samples of these materials were examined by direct microscopy and enrichment culture. Additional insulation samples were desiccated for three weeks over silica drying gel, weighed, then placed over saturated salt in water solutions at known relative humidities. At relative humidities approaching 95%, some insulation samples on an average gained 6% of their dry weight in water.

The existing literature contains strong evidence that characteristics of buildings and indoor environments significantly influence rates of respiratory disease, allergy and asthma symptoms, sick building symptoms, and worker performance. Theoretical considerations, and limited empirical data, suggest that existing technologies and procedures can improve indoor environments in a manner that significantly increases health and productivity.

Surely, nobody has anything against the idea of a sustainable society. But how is it to be achieved? And what can we ourselves do when everybody else insists on taking their car to work? This is how people usually argue. People do not see any direct relationship between their own way of life and the way nature reacts. This has been tackled in Seattle on the western seaboard of the US. This is where the concept of sustainability factors was first tested within the built environment.
