PurposeThe purpose of this study is to develop a condition assessment (CA) model for a building's indoor 21 environments and to improve the building's asset management process.Design/methodology/approachThe methodology is based on dividing the building into spaces, which are the principal evaluated elements based on the building's indoor environmental quality (IEQ). An evaluation scheme was prepared for the identified factors and the analytical hierarchy process (AHP) technique was used to calculate the relative weight of each space inside the building as well as the contribution of each IEQ factors (IEQFs) in the overall environmental condition of each space inside the building. The multi-attribute utility theory (MAUT) was then applied to assess the environmental conditions of the building as a whole and its spaces. An educational building in Canada was evaluated using the developed model.FindingsEach space type was found to have its own IEQFs weights, which confirms the hypothesis that the importance and allocation of each IEQF are dependent on the function and tasks carried out in each space. A similar indoor environmental assessment score was calculated using the developed model and the building CA conducted by the facility management team; “89%” was calculated, using K-mean clustering, for the physical and environmental conditions.Originality/valueIEQ affects occupants' assessment of their quality of life (QOL). Despite the existence of IEQ evaluation models that correlate the building's IEQ and the occupants' perceived indoor assessments, some limitations have led to the necessity of developing a comprehensive model that integrates all factors and their sub-criteria in an assessment scheme that converts all the indoor environmental factors into objective metrics.

Heritage Buildings

PurposeThe purpose of this research is to focus on the evaluation of heritage buildings' sustainability. BIM modeling was necessary for the design of the sustainability assessment model for Heritage Buildings (SAHB). Using ArchiCAD®, energy simulations were performed for two case studies (Murabba Palace, Saudi Arabia, and Grey Nuns Building, Canada), and the developed model was validated through sensitivity analysis.Design/methodology/approachHeritage buildings (HBs) are unique and must be preserved for future generations. This article focuses on a sustainability assessment model and rating scale for heritage buildings in light of the need for their conservation. Regional variations were considered in the model development to identify critical attributes whose corresponding weights were then determined by fuzzy logic. Data was collected via questionnaires completed by Saudi Arabian and Canadian experts, and Fuzzy TOPSIS was also applied to eliminate the uncertainties present when human opinions are involved.FindingsResults showed that regional variations were sufficiently addressed through the multi-level weight consideration in the proposed model. Comparing the nine identified factors that affect the sustainability of HBs, energy and indoor environmental quality were of equal weight in both case studies.Originality/valueThis study will be helpful for the design of a globally applicable sustainability assessment model for HBs. It will also enable decision-makers to prepare maintenance plans for HBs.

Purpose Rapid changes in the environment escalate the requirement of environmental sustainability assessment within built environment. The purpose of this paper is to model the environmental sustainability of facilities management (FM) functions in apparel industry in Sri Lanka. Design/methodology/approach A comprehensive literature review was carried out in order to identify the importance of sustainability assessment for FM, sustainable FM functions and their environmental sustainability indicators. Subsequently, a questionnaire survey was carried out to determine a relative weight of the sustainable FM functions and environmental sustainability indicators through the analytical hierarchy process analysis. Findings Energy management was identified as the most significant FM function in terms of environmental sustainability in apparel industry with a relative performance of 49.12 per cent. Subsequently, the functions of water management (29.39 per cent), maintenance management (11.98 per cent) and waste management (9.64 per cent) obtained the second, third and fourth ranks while asset management (7.85 per cent) was the function which had the least performance score. Relative weights for the environmental sustainability indicators were also determined. Research limitations/implications In respect of the apparel industry, the developed model can be utilised for assessing the environmental sustainability of FM in broader term. Originality/value No proper mechanism was found to assess the sustainability of FM in apparel sector since very fewer research studies were focussed on achieving environmental sustainability in different industries. Hence, the assessment of environmental sustainability of FM in apparel industry is an emerging necessity in the present day, which was addressed in this research.

Purpose This paper sets out to understand the impact of the ambient environment on perceived comfort, health, wellbeing and by extension productivity in the workplace. Design/methodology/approach The research combined an occupant survey considering satisfaction with the ambient environment, health and wellbeing and workplace behaviour with the monitoring of ambient environmental conditions. Findings The paper demonstrates that the ambient environment can have a significant impact on occupant comfort, health and wellbeing, which in turn has implications for built asset performance. Within the ambient environmental factors considered, a hierarchy may exist with noise being of particular importance. Occupant behaviour within the workplace was also found to be influential. Research limitations/implications The research was limited to a single commercial office building, and a wider range of case studies would therefore be of benefit. The research was also limited to the summer months. Practical implications The findings show that an active approach to asset management is required, by continuously monitoring internal environment and engaging with occupants. This must carefully consider how ambient environmental factors and workplace behaviour impact upon occupants’ comfort, health and wellbeing to ensure the performance of the built asset is maximised. Originality/value This paper demonstrates that both occupiers’ workplace behaviour and ambient environmental conditions can have an impact on occupant comfort, health, wellbeing and productivity. The paper strengthens the case for the active management of the workplace environment through environmental monitoring and behaviour change campaigns supported by corresponding changes to workplace culture.

Information Modelling

Purpose – The purpose of this paper is to provide a unique conceptual framework for integrated asset management strategy that includes making use of available facility assessment methods and tools such as BREEAM In-Use, and Leadership in Energy and Environmental Design (LEED); and highlights proposes areas of commonality between these and the use of as-built Building Information Modelling, that ultimately becomes the Asset Information Model (AIM). This framework will consider the emerging requirements for the capture of Building Performance Attribute Data (BPAD), and how these can be managed in order to assist with effective post-construction building performance evaluation. Design/methodology/approach – A review of the current process relevant to the development of as-built BIMs and AIMs was undertaken which included a discussion of BIM standards and of the COBie process. This was combined with data provided by industry practitioners. This led to the concept of BPADs being developed, to be used within existing green building tool, BREEAM In-Use, COBIE and FM/Asset management methods. In turn these methodologies were used to identify possible synergies and areas of integration in AIM-enabled environments. Findings – Recognising the cyclical nature of asset management and BIM, a conceptual model was generated. It was found that BPADs could be aggregated within an AIM model which could influence the delivery of effective facilities and asset management. The model considers the use of existing Building Management Systems (BMS) and Computer Aided Facility Management Systems (CAFMs) and identifies issues associated with the overall sustainability strategy. Originality/value – A conceptual framework is generated that proposes the use of effective information management and aggregation of BPAD within an AIM.

Purpose This paper aims to respond to the high cost of facility management-enabled building information model (FM-BIM) creation and maintenance, a significant and under-researched barrier to adoption for existing buildings. The resultant approach focuses on only value-adding content (“Lean”) developed flexibly and iteratively in collaboration with end-users (“Agile”). Design/methodology/approach Five case studies were developed for university and hospital buildings in collaboration with end-users, guided by the process presented. These informed the refinement of a robust and flexible approach to increase BIM functionality with minimal geometry, focusing instead on the development of specific parameters to map semantic information necessary for each desired FM use. Findings The resulting BIM provided a breadth of model functionality with minimal modeling effort: 15 hours average implementation time per supported FM use. This low level of effort was achieved by limiting geometry to where it is necessary for the FM use implementation. Instead, the model incorporated the majority of geometry by reference and focused on semantic and topological parameters to house FM information. Research limitations/implications This study provides the basis for a new ontology structure focused on defining the rules for hosting asset management data (host entity, parameter type and characteristics) to reduce the reliance on complex geometric model development. Practical implications By prioritizing highly beneficial applications, early investment is minimized, providing quick returns at low risk, demonstrating the value of FM-BIM to end-users. Originality/value The Lean-Agile approach addresses the known research gap of low-effort, flexible approaches to FM-BIM model creation and maintenance and its effectiveness is analyzed through five case studies.

Purpose – 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. Design/methodology/approach – 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. Findings – 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. Research limitations/implications – 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. Practical implications – 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. Originality/value – This paper provides equations and variables to measure a facility's physical, functional and financial performance using both quantitative and qualitative performance assessments.

Purpose The purpose of this paper is to improve the existing model developed by Hsu and Sabherwal (2012) by developing a new dimension of the relationships between a group of constructs (knowledge elements, mediating constructs and facility management [FM] organisational performance) in the model of FM organisational performance. Design/methodology/approach The paper reviews the theoretical studies empirically to all of the knowledge elements (learning culture, intellectual capital and knowledge management) literature, mediating constructs (customer performance, efficiency, innovation and dynamic capabilities) and the organisational performance that relates to FM. Findings The paper identifies the relationships between the knowledge elements, mediating constructs and the FM organisational performance. Subsequently, a proposal of relationships was made to develop the FM organisational performance model. Research limitations/implications The model provides a possible explanation of relationships between the knowledge elements, mediating constructs and the FM organisational performance. Thus, the understanding of the identified relationships will provide a new direction in improving the FM organisational performance. Originality/value Addressing lack of research in identifying the importance of relationships between knowledge and the FM organisational performance, the paper conceptualises the potential relationships into a proposed model. The proposed model integrates with a new mediating construct into the existing research model, which is customer performance. Moreover, knowing that the nature of FM organisation is more towards the non-financial aspects, the paper investigates the nature of the efficiency and organisational performance that is not based on the financial performance, but rather the ability to optimise organisational resources, to achieve organisational goals and customer needs.
