Conserving a sustainable urban environment through energy security and project management practices.

Construction has been highlighted as one sector that could reduce its effect on the environment by implementing more sustainable methodologies. However, there are many different challenges preventing sustainable construction practice, and despite existing research providing advice for carbon emission reduction, these practices are being somewhat neglected. The purpose of this research is to investigate the challenges surrounding sustainable construction practice and the current knowledge on energy security and project management practices that can aid climate change mitigation. The design methodology of this study involves a thorough literature review of existing knowledge on the subject matter followed by primary research. The survey conducted collected quantitative data of 160 valid responses via an online closed ended questionnaire using snowball sampling methods from the construction and engineering professionals working in the UK construction industry. The study found that most participants agree with the encouragement of sustainable construction practices, but are generally unsure about what they can do. Factors such as government involvement and organisation culture have some significance but will rely on further research in order to assess specific influencing variables. The study contributes to existing research on factors surrounding project management and identifies and plethora of areas of improvement, that can be formed into a holistic approach to the current construction industry practice.

Emerging industry 4.0 and Internet of Things (IoT) technologies in the Ghanaian construction industry: sustainability, implementation challenges, and benefits.

Future construction projects will need the implementation of industry 4.0 and Internet-of-Things (IoT) technologies. The construction sector has, however, falling behind other industries in the application of these technologies and is currently facing considerable challenges. One of the industries that lag behind in the use of new innovative technological tools is the construction industry. This study reviews the research work in industry 4.0 and the Internet of Things as they relate to construction and examines key Ghana-based construction professionals and firms to ascertain their level of understanding of these emerging innovative technologies, including the challenges and benefits associated with their implementation. An extensive review of pertinent literature was done to help identify the important paradigms and variables which were cautiously tested. Adopting a quantitative research approach, the attained variables were used to design into a close-ended questionnaire. The sample frame was a survey of people from 154 construction experts and researchers with good standing by using the purposive sampling. Relative importance index (RII) analysis was used to analyzed the data. It was discovered from the findings that smart construction was the most popular industry 4.0 technology in the Ghanaian construction industry. The most important benefit of these technologies is that they will add sustainable policy requirements to tendering, with the most pressing technology being the lack of talent and skills in using industry 4.0 and IoT technologies. The scope of this research is based on the questionnaire survey, proving a sustainable pathway to the construction industry community, which creates its own significance by including key stakeholders and those affected by these technologies.

A systematic managerial perspective on the environmentally sustainable construction practices of UK.

Construction industry, though is the backbone of any economy, still add a significant portion of emissions, utilising energy supplies, and reasoning in bulk of waste production. The sustainable construction practices are the only solution considering the global climatic challenges. Owing its enormous benefits, a lot of sustainable constructions projects are built around the world, both in developed and developing countries. However, considering the innovative material and technological involvement, and lack of knowledge and expertise, such sustainable construction projects are not always successful. This research aims to investigate the barriers and factors impacting sustainability in the construction projects. More specifically, its primary purpose is to have the perspective of managers on the actors and barriers of sustainable construction in the UK. A mixed method was used to collect the data, one in the mean of questionnaire survey, and the second through the case study. To acquire quantitative data, a snowball sampling was applied to collect the questionnaire survey based data from 128 UK construction managerial positions, such as system managers, sustainability managers, project managers and construction managers, etc. The quantitative acquired data was analysed using mean analysis, relevant importance index (RII), correlation and multiple hierarchical regression. The RII analysis discovered that sustainable construction designs is a top drivers of sustainable construction practices, whereas excessive concentration on price is found as the top impediment of sustainable construction practices. It was also shown by the hierarchical regression analysis that stakeholders factors, project management factors and technological factors significantly impact to sustainable construction practice. However, surprisingly the role of barriers was not observed in the sustainable construction practices of the UK. The same findings were also confirmed with the case study analysis of the Kier Group plc, which believes in the sustainable construction practices. Hence, it is needful for the positive sides of these factors be considered and duly exploited. The research findings provide interesting industrial insights towards sustainable construction projects, while providing useful directions to the industrialists, policymakers and construction professionals, not only by reducing the unfavourable effects, but also by proposing the intention of restoring factors of the environment, economic and social sustainability.

Containing a sustainable urbanized environment through SuDS devices in management trains.

Generating an effective and efficient sustainable drainage philosophy is imperative in alleviating the risk of flooding in a complex UK climate that is categorised by excessive rainfall. The Sustainable Drainage Systems (SuDS) approach offers a revolutionary change in using heightened flow rates and large capacities of water to our advantage, while also disguising the attenuated water into the urbanized environment. This research explores the result of integrating several SuDS devices in management trains with the sole purpose of significantly reducing overall water quantity. It will compare and contrast and prove how SuDS is more dependable than the conventional pipe-based drainage system that is characterized by its ability to remove water to the outflow quickly. Furthermore, in order to determine how a SuDS device is implemented into the natural environment, a case study was conducted at a residential area in Gibside View, Winlaton in Gateshead. The research exhibits how the newly implemented Detention basin had to be retrofitted into the already inadequate drainage system that once lived there; all in thought of alleviating the significant flooding events that were once reported to have occurred prior. As a verification method in terms of effectiveness, a questionnaire was conducted through convenient and purposive sampling at the Case Study location; data was accumulated door-to-door inside a 300 m radius of the detention basin and received about 180 valid responses. The results showed persistence of respondents who detailed flooding events prior to installing the Detention basin, who then recognised a fundamental change in the minimization of water quantity and flooding issues. The results of this research showed why Detention Basins continue to be identified as one of the most successful water reduction-based SuDS devices available for development nationwide implementation.

A risky output of variation orders in renewable energy projects: Identification, assessment and validation.

Renewable energy projects (REPs) are constructed to contribute to the eradication of global warming and supporting a sustainable aspect of economies. However, due to their entrepreneurial nature, such REPs are quite prone to severe project variations. Mostly, REPs deviate from their allocated plans, which lead them to the time and cost overrun outcomes alongside numerous other hindering impacts. The current research was intended to understand the critical impacts of project variations during the building activities of REPs. Utilizing a sample of 253 field experts engaged with such REPs at Pakistan, we employed structural equation modeling (SEM) to analyze and confirm our propositions. It was found that cost-related effects were the most significant outcomes in the REPs and their severity was higher than other variation consequences of time-overrun effects, productivity-related effects, risk-related effects, and reputation related effects. Nevertheless, an unexpected outcome was observed regarding the variations, which do not show their negative effects on reputation related aspects in the REPs of Pakistan. Considering its critical findings, this research is a useful tool for project executives that they can formulate certain techniques to tackle such variations and their consequences in REPs. This research likewise aimed to add and extend pertinent literature for REPs by following the outcomes of the current research concerning the impacts of project variations.

Daily dataset of oil prices and stock prices for the top oil exporting and importing countries from the region of Asia.

This data presented in this article is specifically employed from the Asian region based on the top position in the list of oil exporting and oil-importing countries around the world. Asia as the biggest continent on the earth had high consumption of energy [1]. Here we employed the daily prices of crude oil and seven oil trading countries, out of which three are oil exporting (Saudi Arabia, United Arab Emirates, Iraq) and four are oil-importing countries (China, Japan, South Korea, India), from the time period of 1-09-2009 to 31-08-2018. The data is collected from an authentic database Bloomberg. This data is related to the research paper "Volatility spillover impact of world oil prices on leading Asian energy exporting and importing economies' stock returns. Energy, 188 (2019), 116002, https://doi.org/10.1016/j.energy.2019.116002 [2]". This data is useful to compare the oil prices impact on the leading oil trading countries and also compare a set of countries affected most by oil prices' fluctuations, oil-exporting countries or oil-importing countries. Since this data covers the period of latest oil-crisis, so the impact of oil-crisis could also be analysed.
