Abstract
Purpose
The purpose of this research is to show that reliability analysis and its implementation will lead to an improved whole life performance of the building systems, and hence their life cycle costs (LCC).
Design/methodology/approach
This paper analyses reliability impacts on the whole life cycle of building systems, and reviews the up‐to‐date approaches adopted in UK construction, based on questionnaires designed to investigate the use of reliability within the industry.
Findings
Approaches to reliability design and maintainability design have been introduced from the operating environment level, system structural level and component level, and a scheduled maintenance logic tree is modified based on the model developed by Pride. Different stages of the whole life cycle of building services systems, reliability‐associated factors should be considered to ensure the system's whole life performance. It is suggested that data analysis should be applied in reliability design, maintainability design, and maintenance policy development.
Originality/value
The paper presents important factors in different stages of the whole life cycle of the systems, and reliability and maintainability design approaches which can be helpful for building services system designers. The survey from the questionnaires provides the designers with understanding of key impacting factors.

Abstract
Purpose
The purpose of this paper is to summarize the current applications of BIM, the integration of related technologies and the tendencies and challenges systematically.
Design/methodology/approach
Using quantitative and qualitative bibliometric statistical methods, the current mode of interaction between BIM and other related technologies is summarized.
Findings
This paper identified 24 different BIM applications in the life cycle. From two perspectives, the implementation status of BIM applications and integrated technologies are respectively studied. The future industry development framework is drawn comprehensively. We summarized the challenges of BIM applications from the perspectives of management, technology and promotion, and confirmed that most of the challenges come from the two driving factors of promotion and management.
Research limitations/implications
The technical challenges reviewed in this paper are from the collected literature we have extracted, which is only a part of the practical challenges and not comprehensive enough.
Practical implications
We summarized the current mode of interactive use of BIM and sorted out the challenges faced by BIM applications to provide reference for the risks and challenges faced by the future industry.
Originality/value
There is little literature to integrate BIM applications and to establish BIM related challenges and risk frameworks. In this paper, we provide a review of the current implementation level of BIM and the risks and challenges of stakeholders through three aspects of management, technology and promotion.

Abstract
Purpose
The calculation of buildings’ carbon footprint (CFP) is an important basis for formulating energy-saving and emission-reduction plans for building. As an important building type, there is currently no model that considers the time factor to accurately calculate the CFP of hospital building throughout their life cycle. This paper aims to establish a CFP calculation model that covers the life cycle of hospital building and considers time factor.
Design/methodology/approach
On the basis of field and literature research, the basic framework is built using dynamic life cycle assessment (DLCA), and the gray prediction model is used to predict the future value. Finally, a CFP model covering the whole life cycle has been constructed and applied to a hospital building in China.
Findings
The results applied to the case show that the CO2 emission in the operation stage of the hospital building is much higher than that in other stages, and the total CO2 emission in the dynamic and static analysis operation stage accounts for 83.66% and 79.03%, respectively; the difference of annual average emission of CO2 reached 28.33%. The research results show that DLCA is more accurate than traditional static life cycle assessment (LCA) when measuring long-term objects such as carbon emissions in the whole life cycle of hospital building.
Originality/value
This research established a carbon emission calculation model that covers the life cycle of hospital building and considered time factor, which enriches the research on carbon emission of hospital building, a special and extensive public building, and dynamically quantifies the resource consumption of hospital building in the life cycle. This paper provided a certain reference for the green design, energy saving, emission reduction and efficient use of hospital building, obviously, the limitation is that this model is only applicable to hospital building.

Abstract
Purpose
The purpose of this research is to address the existing gap in the study of construction and demolition waste (C&DW) by focusing on its impact on human health throughout the entire life cycle. And this research provides a comprehensive assessment model that incorporates the release of gaseous pollutants and particulate matter during the whole life cycle of C&DW, thereby contributing to a more holistic understanding of its impact on human health.
Design/methodology/approach
The research was conducted in two stages. Firstly, the quantitative model framework of pollutants emitted by C&DW was established. Three types of pollutants were considered, namely nitrogen dioxide (NO2), sulfur dioxide (SO2) and inhalable particulate matter (PM10). Second, disability-adjusted life year (DALY) and willingness to pay (WTP) assessments were used to provide a monetary quantified health impact for pollutants released by C&DW.
Findings
The results show that the WTP value of PM10 is the highest among all pollutants and 8.68E+07 dollars/a, while the WTP value in the disposal stage accounts for the largest proportion compared to the generation and transportation stage. These findings emphasize the importance of PM10 and C&DW treatment stage for pollutant treatment.
Originality/value
The results of this study are of great significance for the management department to optimize the construction management scheme to reduce the total amount of pollutants produced by C&DW and its harm to human health. Meanwhile, this study fills the gap in existing research on the impact assessment of C&DW on human health throughout the whole life cycle, and provides reference and basis for future research and policy formulation.

Abstract
Purpose
The purpose of this paper is to discuss life cycle cost management and highlight the practical challenges related to collecting adequate data and practicing long‐term cost management in an uncertain environment.
Design/methodology/approach
The paper reports a case study conducted in the Finnish Defence Forces. As part of the case study, a life cycle cost model for a case product was developed.
Findings
Activity‐based life cycle cost modeling can provide relevant information for varying product management needs at different stages in the life of a product. Quantification of uncertainty is one of the elements in the modeling that can improve the feasibility of LCC both for cost estimation and tracking purposes.
Originality/value
Only a few empirical studies on life cycle costing have been reported which focus on the defence sector. The paper contributes to our understanding of how LCC can be used in a continuous manner and depicts how LCC can produce a sharpened cost image of a particular product.

Abstract
Purpose
The purpose of this study is to describe life cycle cost (LCC) and life cycle assessment (LCA) evaluation for single story building house in Malaysia. Two objective functions, namely, LCA and LCC, were evaluated for each design and a total of 20 alternatives were analyzed. Two wall schemes that have been adopted from two different recent studies toward mitigation of climate change require clarification in both life cycle objectives.
Design/methodology/approach
For this strategic life cycle assessment, Simapro 8.3 tool has been chosen over a 50-year life span. LCC analysis was also used to determine not only the most energy-efficient strategy, but also the most economically feasible one. A present value (PV)-based economic analysis takes LCC into account.
Findings
The results will appear in present value and LC carbon footprint saving, both individually and in combination with each other. Result of life cycle management shows that timber wall−wooden post and beam covered by steel stud (W5) and wood truss with concrete roof tiles (R1) released less carbon emission to atmosphere and have lower life cycle cost over their life span. W5R1 releases 35 per cent less CO2 emission than the second best choice and costs 25 per cent less.
Originality/value
The indicator assessed was global warming, and as the focus was on GHG emissions, the focus of this study was mainly in the context of Malaysian construction, although the principles apply universally. The result would support the adoption of sustainable building for building sector.

Abstract
Purpose
The main purpose of this paper is the incorporation of life-cycle costs (LCC) and whole-life costing (WLC) method and the taxation environment into the investment appraisal procedure for commercial real property projects.
Design/methodology/approach
The paper initially presents the methodologies of LCC and WLC together with the NPV measure for the evaluation of real estate investments. These methods are incorporated into a decision-making model using mathematical approaches. The model is applied to a typical commercial property project (office building) in order to explore the significance of impacts from changes in structured variables and the taxation environment by introducing direct, indirect and property taxes in the evaluation of commercial real estate projects.
Findings
Testing of the methodology on the Greek economic environment revealed that time, cost, the tax regime, the financial variables of funding and the monetary and fiscal environment in a commercial real property project are the main variables of net present value (NPV) of the investment.
Practical implications
From the calibration of any impact from affected variables, decision-making aiding tools can be extracted for controlling the project throughout its entire life-cycle.
Originality/value
An integrated WLC mathematical model for the investment appraisal of commercial property projects is introduced. The herein proposed methodology contributes to taxation policy and real estate theory in general and assists industry professionals in effective commercial property management and decision-making.
