The purpose of this paper is to synthesize the previously established list of key performance indicators (KPIs), to identify and categorize the core performance indicators that are measurable and quantifiable.

A literature-based qualitative approach is adopted for accumulating desired information on identifying and categorizing the core indicators. The list of KPIs established in an earlier paper is narrowed down considering the future research needs suggested by the literature.

The quantifiable and measurable core indicators are identified and categorized in the form of a list. The core indicators are defined and the variables required to quantify them are described by citing peer-reviewed literature.

This paper represents the first step toward establishing a relevant list of quantifiable and measurable core KPIs. Future research papers could emphasize derivation of mathematical expressions for determining the identified core KPIs and validating these KPIs using simulation of real building data.

The need to establish a concise and relevant list of quantifiable and measurable KPIs that could express more than one type of information about a facility's performance is identified in this paper. This paper presents and describes a narrowed down list of core KPIs, which could be utilized by facility management industry professionals while performing a holistic performance assessment.

This paper provides a list of core KPIs that could express more than one aspect of a facility's performance and that is measurable and quantifiable.

The purpose of this paper is to identify key variables that affect the quantifiable key performance indicators (KPIs) and to derive equations to measure these indicators. Qualitative KPIs are also discussed in terms of the aspects that need to be covered while carrying out qualitative performance assessment.

A combination of literature and an industry opinion-based qualitative approach is applied to develop equations to calculate the quantifiable KPIs. A facility asset management consulting firm is included in the process of deriving the equations. Key aspects of a facility's qualitative performance assessment are categorized and discussed by performing a literature review.

Mathematical expressions for core performance indicators are presented and discussed along with key variables. In addition, the information needed to quantify these core indicators is also discussed.

This paper represents the second step towards establishment of a relevant list of quantifiable and measurable core KPIs, which were identified and categorized in Part I of this paper. In Part II, the authors derive equations to quantify the core KPIs. Future research is needed to use relevant information from industry for validating these equations.

A need for a concise and relevant list of KPIs was identified in Part I of this paper. Part II provides an approach to quantify the core KPIs based on information that is available in the industry. This research will help facility management professionals in not only selecting the indicators of choice, but also quantifying them based on available information yielding enhanced facility management decisions with measurable facility performance outcomes.

This paper provides equations and variables to measure a facility's physical, functional and financial performance using both quantitative and qualitative performance assessments.

The recurrent embodied energy (REE) is the energy consumed in the maintenance, replacement and retrofit processes of a facility. The purpose of this paper was to analyze the relationship of REE with the service life and life cycle embodied energy. The amount of variation in the reported REE values is also determined and discussed.

A qualitative approach that is known as the literature based discovery (LBD) was adopted. Existing literature was surveyed to gather case studies and to analyze the reported values of REE.

The reported values of REE showed considerable variation across referred studies. It was also found that the reported REE values demonstrated a moderate positive correlation with the service life but a very strong positive correlation with the life cycle embodied energy of both the residential and commercial facilities.

This review paper pointed out the importance of the maintenance and replacement processes in reducing the life cycle energy use in a facility. Future research could focus on performing case studies to evaluate this relationship.

The findings highlight the significance of REE in reducing the life cycle energy impacts of a facility. As facility managers routinely deal with maintenance and replacement processes, they hold an important responsibility of reducing the life cycle energy.

The findings of the paper would motivate the facilities management professionals to prefer long service life materials and components during the postconstruction phases of a built facility.
