“…The assessment is based upon scores awarded according to a set of performance criteria such as energy consumption, and indoor environmental quality. To evaluate environmental impacts of the refurbishment alternatives, LCA is commonly used (Ghose et al, 2017). From the economic perspectives, sustainable refurbishment offers a reduction of energy use; thus the lowering of investment and operating costs during the building's lifetime can lead to lower life-cycle cost.…”

Purpose Any building refurbishment is challenging and school buildings offer no exception. They are increasingly in need of refurbishment due to their age and evolving teaching and learning. The purpose of this paper is to present an overview of literature on sustainable refurbishment so as to identify key lessons from selected successful refurbishment projects. The review findings are expected to contribute to the development of refurbishment plans in an effective and innovative manner that should extend building’s service life, focus on resource efficiency, and comfort their users. It will also contribute to knowledge base of refurbishment and suggest future directions for research. Design/methodology/approach The paper has undertaken a literature review on the sustainability assessment of buildings and frameworks for sustainable refurbishment. Besides, the work also provides a review of recent successful refurbishment projects to collect and structure systems experiences which can be adopted in developing a sustainable refurbishment strategy for school buildings. Findings Findings include three groups of lessons in terms of reasons, process and barriers in the selected refurbishment projects that assist stakeholders to prepare a suitable refurbishment plan for their school buildings. The potential of 3D scanners and BIM applications in the refurbishment process will also be reviewed in order to develop a proposed framework of 3D scanner vs BIM for the refurbishment process. Recommendations highlight the role of a national strategy as a driving factor for applying the advantages of information technology to enhance optimal solution selection processes to get better and more sustainable results. Originality/value The conceptual framework for 3D scanner and BIM applications within sustainable refurbishment for school buildings is currently under researched, and the findings aimed to address such a gap when considering 3D scanners and BIM applications in the refurbishment process.

“…For example, in NZ, the incentive of warming up the existing houses led to insulation retrofits [18]. The insulation has been typically installed to some elements of the house only, like walls, floors, or ceilings but rarely to the whole building envelope [19]. As a result of these enhancements, the energy balance has been improved.…”

Many New Zealand houses are energy-inefficient, unhealthy, cold, mouldy, and damp. Therefore, a new approach to building design is imminent. This article proposes a framework for the transformation of housing that integrates construction planning and design, optimization, and control tools at strategic, tactical, and operational levels. The introduced Complex Integral Design New Zealand (CIDNZ) represents a comprehensive and balanced system-based design and delivery process that facilitates and accelerates cross-disciplinary and trans-disciplinary expertise and knowledge. CIDNZ delineates a new way of designing the process based on integral, complex, and systems thinking. The emerging novel understanding of sustainability, which guides the transformation process, might lead to a balance between individuals, groups, society, and existing ecosystems. CIDNZ comprises all stages in the life cycle of buildings and all significant factors in the architecture, engineering, and construction industry, particularly, people, processes, technology, and the environment. Therefore, the entire construction process that implements a system approach to buildings as a vital part of environmental systems, goes from the environment to humans and vice versa and offers unlimited possibilities. The consequent practical application of these principles might eliminate or reduce the design defects and lead accordingly to the reduction of costs involved in their rectification.

“…A study about the major refurbishment of an office in Auckland, New Zealand with changing the building envelope with additional insulation, modified wall-window ratio, solar shading as well as technical replacement of the lighting and HVAC system showed that deep energy refurbishment is associated with significant environmental impacts mainly due to the use of energy-intensive construction materials (Ghose et al, 2017).…”

Energy consumption by occupants during utilization phase concerns the increase of global warming potential and a shortage of energy resources. Energy consumption in an effective way decreases the risk of global warming. Use of materials with high embodied energy and embodied carbon in building components may improve the energy performance of the building, but it can ameliorate global warming. The issue of Life Cycle is quite new in the Middle East, so is it effective or does it work in developing countries. One of the goals of this study is to use three different wall types in a two-story office with close embodied energy and U-value (overall heat transfer coefficient) and compare the performance of each wall in the building from the Life Cycle point of view. Subsequently, analyzing the importance of other factors such as embodied carbon and transportation in choosing appropriate material in the construction sector. According to this study, even in countries like Iran (''which holds the world's fourth-largest proved crude oil reserves and the world's second-largest natural gas reserves'') with very low amount of database about the embodied energy, the right material should be chosen to reduce the fuel consumption and CO 2 emission.
