Occupant behaviours in the buildings are not only random and uncertain but also related to each occupant’s habitual preference. This leads performance gap between actual expected energy consumption buildings. Therefore, accurate information modelling with regard occupant behaviour important for reliable simulation energy-saving optimization design. Existing studies on models office space usuall...

Global competitiveness and increasing performance requirements have placed facilities management (FM) under constraints of limited resources, particularly in non-core aspects of facilities, such as maintenance and operations. The hypothesis applied in this research is that the actual service life of buildings, their occupancy and their ambient environmental conditions affect the required mainte...

Contemporary office buildings commonly experience changes in occupancy patterns and needs due to changes in business practice and personal churns. Hence, it is important to understand and accurately capture the information of such trends for applications in building design and subsequent building operations. Detection of occupant presence has been used extensively in built environments for appl...

In this paper, we describe and compare three different uncertainty calculi techniques to build occupancy grids of an unknown environment using sensory information provided by a ring of ultrasonic range-finders. These techniques are based on Bayesian theory, Dempster–Shafer theory of evidence, and fuzzy set theory. Several sensor models are presented to handle uncertainty according to the select...

The infringements and suits of patents have been increased in many technological fields. Since a patent is an intellectual property to protect inventors’ exclusive rights of developed technologies, technological pre-occupancy is very important to the development of companies. For the technological pre-occupancy a patent registration time is surely important. In this paper we propose a predictiv...
