Current state and future challenges in building management: Practitioner interviews and a literature review

Building management tools, such as building automation systems (BASs) and computerized maintenance management systems (CMMSs), are intended to support the efficient operation of building systems while maintaining occupants' comfort. However, observing current building management practices in commercial and institutional buildings demonstrates several challenges that compromise the core objectives of building management tools. To this end, this paper aims to provide recommendations to commercial and institutional building management stakeholders for improving current building management practices in North America. The recommendations are based on interviews with thirty building management professionals, examples and evidence from relevant literature, and the authors' involvement in resolving building management-related issues. The paper first documents current building management practices including professionals' backgrounds and qualifications, approaches and tools used, coordination, and building occupants’ involvement. Then, barriers to improving current building management practices are outlined including knowledge, technology, and organizational challenges. Finally, short- and long-term goals to improve current building management practices are outlined. This paper is intended to serve as a roadmap for improving building energy management practices for both researchers and industry.
