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.

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.

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.

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.

The purpose of this paper is to demonstrate that the result of an optimisation via life cycle costs (LCC) depends on the assumptions made throughout the process of calculating LCC.

A framework is used to structure the assumptions made in the process of calculating LCC. These include the following three pairs: technical versus economic life‐span, static versus dynamic calculation method or costs only versus income minus costs. In a broader sense, these LCC are referred to as the life cycle economy (LCE). Two case studies form the basis for the LCC calculations. Using different assumptions, the LCC of virtual design variations of these buildings are compared to each other.

The rankings drawn from the calculations differ according to the chosen calculation method, i.e. the chosen variation for the optimisation of a building is not consistent.

This is essentially an exploratory study and the prognosis of future cash flow in relation to certain design variations requires further research.

The credibility of life cycle costing should improve with a greater transparency of assumptions in the context of the outlined framework.

All players in facilities management who support their decisions with LCC will benefit from this quantification of the impact of different calculation methods. The extension of LCC to LCE will help planners, investors and owners of real estate in evaluating building options with respect to quality, image, flexibility or comfort.

The purpose of this paper is to focus on the ongoing discourse centred on enhancing building performance to provide an interpretation of life cycle cost (LCC) analysis, directly applicable to building construction in coastal areas located in tropical wet–humid settings.

A survey of 50 buildings based on physical observation is carried out to identify typical failure patterns in wet‒humid environment. Further, a comparative initial construction cost and LCC analysis is computed for two alternative building schemes with identical floor plans: Scheme A using sound construction and detailing to guard against future maintenance problems and Scheme B adopting the typical designs evident in the study area.

The result of the analysis shows that in the long-run scheme, A is an economically more viable option than B, as the increased initial costs are entirely offset by the reduced running cost.

The contextual nature of LCC analysis poses difficulties in applying the evidence provided in this study to provide a generalisable financial justification to buildings clients.

The outcome of the study provides analytical validation to overcome resistances and enables informed decision making by clients, which is necessary to promote transition from conventional to environmentally responsive design choices suitable to wet–humid conditions.

The study provides an interpretation of LCC analysis, directly applicable to building construction in the tropical wet–humid setting of coastal areas against the backdrop of inconsistencies in the practical application of the theory of LCC.

Airports are booming in China, to enlarge their capacities and stimulate economic development. Large-span spatial steel structures are commonly used in the terminal buildings of airport projects. Their advantages include prefabrication, strength, usability, adaptability and aesthetic quality. To manage large-span spatial steel structure projects, building information modeling (BIM) is recommended. Although there are plenty of studies on BIM application in steel structure projects, it is still rare to apply BIM to optimize the schedule and cost of steel structures, especially for airport projects.

This paper aims to develop a framework in which BIM and a time-cost optimization model are integrated to optimize construction costs and the duration of large-span spatial steel structure projects. A real case study was conducted to verify the feasibility of the BIM-based time-cost optimization model in an airport terminal building, which was built with a large-span spatial steel structure.

The results preliminarily support the reliability of the proposed BIM-based time-cost optimization model. The BIM-based time-cost optimization model will benefit construction planning for professionals and enrich relevant research on the application of BIM in large-span spatial steel structure projects.

The steel structure is difficult to control budgets and progress. This paper is expected to be adopted for optimizing the time and cost plans for projects involving steel structures in airport terminal buildings.

In order to establish sustainable development, there is a need to focus on solutions effectively improving environmental performance. Effectiveness is the product of significance and improvement potential. For buildings, the supporting structure is the predominant environmental load by materials, hence significant. The purpose of the studies presented in this paper is to determine the improvement potential of the supporting structure of buildings and explore other sustainable solutions effectively enhancing environmental performance.

For the same office layout, various combinations of structural components at different spans were studied. The environmental load of these variants was determined by means of an life cycle analysis (LCA)‐based model.

The studies presented in the paper demonstrated an environmental difference by a factor of 5 between the solutions performing worst and best. The optimal combination is the uncommon solution of TT‐slabs with timber beams and columns, expecting to establish an improvement factor of 4 with respect to common practice.

The findings of the studies presented suggest another way of building, with common structural components but whose combination is not common at present.

So far, sustainable building has not focused enough on effective solutions and has had little means to do so. Approaching the supporting structure of buildings rather than small, ineffective adaptations will significantly improve environmental building performance. An elaborate LCA of supporting structures had never been done before. The paper, on the one hand, rationalises sustainable building and, on the other hand, supports effective sustainable design.

A striking feature of Jaques' work is his “no nonsense” attitude to the “manager‐subordinate” relationship. His blunt account of the origins of this relationship seems at first sight to place him in the legalistic “principles of management” camp rather than in the ranks of the subtler “people centred” schools. We shall see before long how misleading such first impressions can be, for Jaques is not making simplistic assumptions about the human psyche. But he certainly sees no point in agonising over the mechanism of association which brings organisations and work‐groups into being when the facts of life are perfectly straightforward and there is no need to be squeamish about them.

The purpose of this review is to integrate and organize past research findings on affective, normative and continuance occupational commitment (OC) within an integrative framework based on central life span concepts.

The authors identified and systematically analyzed 125 empirical articles (including 138 cases) that examined OC with a content valid measure to the here applied definition of OC. These articles provided information on the relationship between OC and four distinct life span concepts: chronological age, career stages, occupational and other life events, and occupational and other life roles. Furthermore, developmental characteristics of OC in terms of construct stability and malleability were reviewed.

The reviewed literature allowed to draw conclusions about the mentioned life span concepts as antecedents and outcomes of OC. For example, age and tenure is more strongly positively related to continuance OC than to affective and normative OC, nonlinear and moderating influences seem to be relevant in the case of the latter OC types. The authors describe several other findings within the results sections.

OC represents a developmental construct that is influenced by employees’ work- and life-related progress, associated roles, as well as opportunities and demands over their career. Analyzing OC from such a life span perspective provides a new angle on the research topic, explaining inconsistencies in past research and giving recommendation for future studies in terms of dynamic career developmental thinking.

The aims and objectives of this research are to establish whether or not the transition into green building in high-rise construction is practical. This is after considering several perspectives including financial, economic, environmental, and social. This subsequently leads to an evaluation on whether or not the continuation with a standard conventional build of high-rise buildings remains to be the most feasible option. Such objectives, therefore, aim to allow for validation of how and why high-rise construction designs are impacted through green buildings effects.

Through six defined steps, the methodology commences with an introductory section of what it means to build green. This section is further broken down to evaluate what factors are involved in constructing a green building. Furthermore, the life cycle energy (LCE) is used as a framework to evaluate the knock-on effects of green buildings and subsequent high-rise construction design implications.

Through defining the ongoing relationship of green materials and sustainable design, various implications for high-rise constructions were discovered. First and foremost, it was determined that the LCE is the central consideration for any high-rise building design. In evaluating the LCE, and overall operating energy of the 50-year cycle of a building was carried out. As the results showed, the operating energy represents around 85% of the total energy that is consumed at the end of the 50 years cycle of the building. Precise LCE calculation can lead to a more efficient design for high-rise buildings. As a result, an increased understanding of the current status of green buildings within the construction industry is paramount. This understanding leads to a better insight into the contributing factors to green building in high-rise construction and the construction industry in general.

The potential contribution that can be gained from this research is the awareness that is raised in the research and development of green buildings in high-rise construction. This can be achieved by using certain materials such as new energy-efficient building materials, recycled materials and so on. This research will contribute to defining a new way of sustainable buildings, particularly for high-rise construction. The outcome of the research will be beneficial for practitioners such as design engineers and other related professions.

The purpose of this paper is to identify the sustainability conditions of primary schools in Turkey within the scope of the life cycle assessment (LCA). It is aimed to develop optimum alternatives to reduce the environmental impact of primary schools and reach environmental sustainability targets of the sustainable development goals in Turkey.

From the construction project of 103 buildings located in Istanbul, 10 case buildings with various typical plans were chosen for analysis. The results regarding their life cycle energy and carbon emission for material production, operation and maintenance stages were calculated for a lifespan of 50 years. Results were evaluated and compared within the scope of environmental sustainability. Optimum alternatives for improving the environmental sustainability and performances of selected case buildings’ facades were developed, and the life cycle energy and carbon emission for proposed conditions were calculated. The obtained results were evaluated for current and proposed conditions.

Results showed that reinforced concrete material contributes the most to the life cycle-embodied energy and CO₂ emission of buildings. Cooling load increases the life cycle operational energy (LCOE) and CO₂ emission of buildings. Using high-performance glazing significantly reduces LCOE and CO₂ emission. Recycled and fiber-based materials have significant potential for reducing life cycle-embodied energy and CO₂ emission.

This study has been developed in response to achieving sustainable development targets on public buildings in Turkey. In this regard, external walls of primary schools were analyzed within the scope of LCA and recommendations were made to contribute to the policies and regulations requested by the Government of Turkey. This study proves that alternative and novel materials have great potential for achieving sustainable public buildings. The study answers to questions about reducing the environmental impact of primary school buildings by using LCA approach with a holistic point of view.

During the 1960s, thousands of high‐ and medium‐rise single sided corridor blocks were designed and constructed using prefabricated concrete cladding systems. Most were characterised by inferior quality material and poor workmanship, poor supervision and inadequate environmental services which subsequently deteriorated to a state of disrepair. The main culprits were condensation, water ingress and cold bridging effects owing to low energy efficiency standards and lack of thermal insulation. It was initially contemplated that at the end of their life span these problems would be remedied by adopting “high‐tech” components involving composite cladding methods and highly automated environmental services to improve the operational efficiency and optimise their long‐term durability and life cost cycle. However, the cost has proved to be beyond client affordability. Meeting the requirements of today’s users and the current building regulations necessitated rethinking of the whole process; and alternative cost‐effective maintenance and energy efficient approaches had to be developed. This paper critically evaluates the approach to low‐cost maintenance and refurbishment of high‐rise buildings in parts of Birmingham, UK.
