“…An obvious solution would be to replace older stock with newer, greener office buildings. Of course, however, construction generates significant GHG emissions, consumes energy and generates large amounts of waste in their own right (Banihashemi et al, 2018). Consequently, the benefit of constructing a 5-star NABERS-rated building over that of merely upgrading an existing building to a 4.5-star rating would only materialise some 290 years into the future (Marquez et al, 2012) -far beyond the current life of buildings.…”

Purpose The built environment is a major source of carbon emissions. However, 80 per cent of the damage arises through the operational phase of a building’s life. Office buildings are the most significant building type in terms of emission-reduction potential. Yet, little research has been undertaken to examine the barriers faced by building operators in transitioning to a green operation of the office buildings in their care. This study aims to identify those barriers. Design/methodology/approach Building facilities managers with between 7 and 25 years’ experience in operating primarily Melbourne high-rise office buildings were interviewed. The sample was taken from LinkedIn connections, with ten agreeing to participate in semi-structured interviews – out of the 17 invitations sent out. Interview comments were recorded, coded and categorised to identify the barriers sought by this study. Findings Seven categories of barriers to effecting green operation of office buildings were extracted. These were financial, owner-related, tenant-related, technological, regulatory, architectural and stakeholder interest conflicts. Difficulties identifying green operation strategies that improved cost performance or return on investment of buildings was the major barrier. Practical implications Government, policymakers and facilities managers themselves have been struggling with how to catalyse a green transition in the operation of office buildings. By identifying the barriers standing in the way, this study provides a concrete point of departure from which remedial strategies and policies may be formulated and put into effect. Originality/value The uptake of green operation of office buildings has been extremely slow. Though barriers have been hypothesised in earlier works, this is the first study, to the best of the authors’ knowledge, that categorically identifies and tabulates the barriers that stand in the way of improving the green operational performance of office buildings, drawing on the direct knowledge of facilities experts.

PurposeIntegrated project delivery (IPD) is highly recommended to be utilised with building information management (BIM), specifically with BIM level-3 implementation process. Extant literature highlights the financial management challenges facing the proposed integration. These challenges are mainly related to the IPD compensation and the conventional cost control approaches that are not consistent with IPD principles. As such, this paper presents an integration of several methods to support automating risk/reward sharing amongst project parties thus enhancing IPD core team members’ relationship.Design/methodology/approachThe literature review was used to highlight the challenges that face the IPD-based cost management practices such as the risk sharing/reward sharing amongst IPD core team members and potential methods to bridge the revealed IPD gap. A framework was developed by integrating the activity-based costing (ABC) – as a method to analyse the cost structure – and earned value management (EVM) to develop mathematical models that can determine the three main IPD financial transactions (i.e. …) fairly. To demonstrate the applicability of the developed system, a real-life case study was used, in which, promising results were collected in regard to visualising the cost control data and understanding of the accumulative status of the project cost and schedule for team members.FindingsA centralised cost management system (CCMS) for IPD is developed to enable the IPD cost structure as well as automating the risk-sharing/reward-sharing calculations. This system is linked with a web-based management system to display the output of proposed risk-sharing/reward-sharing models. Moreover, a novel grid is developed to show the project status graphically and to respect the diversity in core team members backgrounds. In addition, the case study showed that the proposed integration of different methods (ABC, EVM, BIM and web-based management system) is interoperable and applicable.Originality/valueThis research presents a comprehensive solution to the most revealed challenges in cost management practices in IPD implementation. The outcome of this research contributes to the body of knowledge through presenting new extensions of the EVM to be used with the IPD approach to calculate risk/reward. Moreover, the implementation of the proposed tools such as centralised cost management system (CCMS) and CCMS for IPD web system will enhance/foster the implementation of the IPD in conjunction with BIM process.

The Integrated Project Delivery (IPD) in integration with Building Information Modelling/Management (BIM) is an optimal approach for delivering construction projects. This is, however fraught with complications, due to the inability of current cost management practices to determine fair risk/reward ratio in IPD arrangements. Previous research has established the advantages of Earned Value Management-based (EVM) method for risk/reward sharing, as well as, how Activity Based Costing (ABC) method can facilitate automating the sharing process. This study proposes an innovative approach to exploit the capabilities of these techniques coupled with BIM in automating/optimising the process of IPD risk/reward sharing. This includes providing mathematical equations for risk/reward sharing and developing a model that strengthens IPD parties' relationships. The process is enhanced through developing an EVM-Web grid that enables the participants to easily track their costs on computers and mobile devices. To demonstrate the applicability and validity of the proposed model, it is applied on a real-life case and displays promising results in terms of flexibility in allocating risk/reward for varying scenarios.
