Abstract

The level of moisture a construction is exposed to may have an adverse effect on health and structure. Using straw, an organic material, as the construction medium, introduces concerns about biodegradability and spore germination, highlighting the uncertainties surround the level at which straw is susceptible to decay. A physical model is presented in this thesis offering a method by which to quantify and evaluate the risk posed to straw bale constructions from moisture. The model, utilising the development of an innovative Risk Assessment System based on fuzzy logic, is supported by empirical research conducted in static and dynamic environments. The model relies upon the interpretation of data provided by monitoring devices, and an understanding as to the complexities of vapour transition through a straw bale and the interaction of moisture within. Using commonly descriptive terminology to describe the risk posed to the straw, the model, is capable of providing a greater understanding of straw bale construction and advising interested parties on potential weaknesses, taking into account: moisture, temperature, historic and predicted environmental conditions, limitations of analytical techniques, and the effect of direct sunlight. The concept of the model is to provide an early response mechanism to warn of the potential of adverse effects and thereby averting the need for destructive investigation and remedial action.
