Conceptual framework for improved management of risks and uncertainties associated with the performance of the building enclosure

Abstract

The building enclosure has a substantial impact on the overall performance of a building, especially in relation to moisture safety, energy use, environmental footprint and economy. Although the introduction of novel building technology can increase the risk of failures in terms of reduced building performance, failures can also result from the recurrence of past mistakes while using well established building technologies. This indicates that the dissemination of existing knowledge, often documented in project reports, handbooks or experience databases, is not always carried out in an efficient way. One way of addressing the issue is by increasing awareness concerning potential risks and uncertainties in the building process. The current paper presents a conceptual framework which has the broader aim of promoting risk awareness, improving the treatment of uncertainties and ultimately facilitating risk informed decision making during the modern design and construction process. The framework incorporates risk treatment with BIM based design and construction and could be supported by existing failure/damage and/or experience databases or knowledge systems.
