Systems-theoretic process analysis (STPA) in building energy risk management

Abstract

As building energy management becomes a complicated process, traditional risk analysis is not adequate to address the management needs and advanced complex modelling techniques are required to handle the multi-dimensional synthesis of risks in the electricity systems. STPA (System-Theoretic Process Analysis) is a new hazard analysis technique using concepts of system and control theory. In this paper, the development of a risk management structure in the field of building energy management is presented. The hazard analysis process based on SafetyHAT information tool is applied for building operation 'accident' prevention, by illustrating the usage of the proposed tool. For this purpose, a case study considering a holistic energy management system in the tertiary building sector is examined.
