1.7.3 Conceptual Design of Building Automation System by Applying Systems Engineering Approach

Abstract

AbstractAs the 21st century signifies an information‐oriented society, the computer integration takes place in all walks of human presence. Needs for computer and network‐integrated building present new challenges in building industry. After the first intelligent building appeared in USA in 1984, it gradually became an essential capability for the building industry requirement these days. Intelligent Building System(IBS) is very complex because there are many subsystems such as telecommunication(TC), office automation(OA), building automation(BA), construction environments, etc. During the planing phase of IBS development, therefore, systems engineering must be performed to analyze stakeholder's requirements to build an optimized system while minimizing trial‐and‐error expenses and risks. This paper presents a conceptual design of BAS by applying systems engineering methods. That is, we developed an IBS subsystem specification for building automation subsystem, which is a part of IBS, using the methodology of requirement analysis, functional analysis, synthesis, and verification where we used a computer‐aided systems engineering tool, RDD‐100, as an example s/w for system design efficiency and product design knowledge management.
