Abstract
This paper tries to show that microenvironment defines the precise conditions of solid materials and the immediate layers of liquid or gas prevailing at the site where chemical of physical processes of deterioration are taking place. It aruges that the microenvironment depends on many factors, including weather, design and material characteristics, and that it is not likely that this system will yield easily to analysis and prediction. Thus, it emphasizes the importance of measuring the conditions of the microenvironment as a guide to the direction of future studies and investigations. It argues also that the use of individual weather elements may be limited because the sequence in which events occur, including simultaneous occurrences of various elements is important. This paper suggests that the following parameters of the microenvironment should be measured or monitored; surface temperature, surface moisture as time-of- wetness; occurrence of near-saturated state of porous materials during freezing conditions; total deposition of pollutanta on exposed surfaces; and UV radiation dose.
