“…Design decisions have the potential to significantly influence the future maintenance requirements of the facility, which, in turn, affects the total cost (Ali et al , 2013; Dunston and Williamson, 1999; Waziri, 2016; Ladinski, 2017; Jandali and Sweis, 2018a, b). Accordingly, consideration for the maintainability of the facility at the early design stages increases the likelihood of lowered levels of maintenance at the operational stage of the facility (Chew et al , 2004; Abeydeera et al , 2017; De Silva et al , 2012; Wang et al , 2013; Chew et al , 2017). Furthermore, given that contemporary facilities are expected to meet higher standards and users’ expectations, the influential role of the design stage has become even more pronounced compared to past years (Chew et al , 2004).…”

Purpose The purpose of this paper is to investigate the current practices of the early facilities management (FM) involvement during the design development and review stages (DDRS), and recommend activities aimed at achieving better integration. Design/methodology/approach A comprehensive literature review was conducted to ascertain the challenges faced by the integrated design team (IDT) in the absence of the facilities managers’ review of design solutions, and underscore the significance of the early involvement of facilities managers during the DDRS. A questionnaire survey was then developed for collecting data on eight aspects of the current practices of early FM involvement during the DDRS. The questionnaire survey was administered to the FM departments of 13 long established, public universities in Saudi Arabia. Ten responses were obtained and analyzed. Findings The findings suggest that the early involvement of the FM department enhances the operation and maintenance of facilities. This has been measured through reductions in the number of architectural, structural, electrical, plumbing, heating, ventilating and air conditioning defects. Practical implications Recommendations were provided to facilitate the process of integrating the practices of two influential stakeholders of building projects. These recommendations encompass the need for maintainability considerations at the early schematic stage, the necessity of direct contact between the two parties and the necessity of facility managers’ increased familiarity of the design stage activities, among other recommendations. In this way, the study promotes the awareness of the significance of integrating FM with the IDT at the DDRS. Originality/value This study contributes to the literature and practice by presenting a detailed analysis of the integration process between the FM department and the IDT. Furthermore, the outcomes of the integration between the parties were measured to assess the effectiveness of the collaboration and highlight the possible areas of improvement.

“…Research in this area has revealed that there is a basic level of understanding surrounding the benefits that may be reaped if a transition to the green building was made. The level of ignorance in this field has proven to be a large contributor to the effects on the environment from the construction industry (Zhang and Canning, 2011;Gharehbaghi, 2017;Chew and Conejos, 2017;Eckelman et al, 2018).…”

PurposeThe 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.Design/methodology/approachThrough 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.FindingsThrough 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.Originality/valueThe 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.

“…Nanostructured titanium dioxide façade coatings Nanostructured titanium dioxide particles are primarily in the 1-100 nanometers size range and are transparent and not inert (Bakker, 2008), which has self-cleaning function that washes away dirt through photocatalytic activity based on UV radiation and hydrophilicity (Chew et al, 2017a). Nano-facade coating is used as an anti-staining coating on building facades to allow ease in maintenance and less maintenance cost than ordinary façade coatings (Midtdal and Jelle, 2013).…”

“…The lack of maintainability consideration on green building technologies in the planning and design stage has led to the study on the maintainability of green building technologies (VGS, nano-façade coating, BIPV and LED Media Wall) in tropical conditions (Chew et al, 2017a(Chew et al, , 2018aChew and Conejos, 2016). This is primarily due to the issue of incorporating these green features in the effort to be "fashionable" rather than serving its purpose (Snyder, 2008).…”

PurposeThe self-cleaning properties of nanostructured titanium dioxide facade coatings are useful in Singapore's tropical climate. However, its potential maintenance issues need to be determined right at the design stage. The purpose of this paper is to highlight the development of the design for maintainability tool which is a multicriteria design decision score sheet that evaluates the maintainability potential of nano-facade coating applications on high-rise façades with concrete and stonemasonry finishes and curtain walls.Design/methodology/approachQuantitative methods (expert and practitioner surveys) are conducted in this research study. Analytic hierarchy process (AHP) and sensitivity analysis were used to develop a robust Design for Maintainability tool.FindingsSafety measures indicator received the highest weighted score by experts, while the maximizing performance, minimizing risk, minimizing negative environmental impact and minimizing consumption of matter and energy were the top ranking main criteria by both experts and practitioners. The top ranked design for maintainability sub-criteria identified by practitioners and experts were risk management, maintenance considerations, climatic conditions, safety measures, lifecycle cost and maintenance access, sun's path, rainfall intensity, biological growth measures and building age profile.Originality/valueMost researches on the maintainability of nano-façade coatings uses experimentation to test the durability of nano-façade coatings, while this study focuses on design based empirical data such as establishing and ranking the list of design for maintainability criteria or indicators to minimize future defects and maintenance issues. The design for maintainability tool contributes to the maintainability of nano-façade coatings leading to maximizing its performance while minimizing cost, risks, resource consumption and negative environmental impact.
