  Conventional buildings consume large amounts of energy and are the source of greenhouse gas emissions contributing to climate change. The shortage of green buildings in Pakistan have been said to be due to shortage of knowledge of the benefits of essential green building materials and the absence of  a regulatory framework. The study is qualitative and quantitative and is divided into two parts. This review paper focuses on awareness in the Pakistan's local construction market concerning green buildings through a survey questionnaire. Data collection procedure consists of 60 questionnaires related to green building construction awareness and priorities within Karachi's construction sector. Also, a focus group and personal interviews conducted with at least 5 professionals working in local construction projects are analyzed. The research questions formed from detailed literature review were analyzed and found that energy conservation, environmental/resource conservation and improving indoor environmental quality are major driving factors for green building development. Similarly, there is a lack of knowledge of green construction methods and regulations and lack of support from the government. This has been found as the major barrier in going towards green construction. We recommend policy directions towards this end and elaborate points of concern to the authorities.

Purpose Green building is a promising approach to improve resource efficiency and achieving sustainable development. The success of green construction projects is closely associated with the performance of project managers (PMs), while job satisfaction plays a major role in the performance of PMs. However, the emphasis placed on the job satisfaction of PMs in green construction projects remains minimal. The purpose of this paper is to identify the relationships between the job satisfaction of PMs and its key influencing factors in green construction projects, and to propose feasible strategies to improve the job satisfaction of PMs. Design/methodology/approach A questionnaire survey is conducted, data collected from 105 construction PMs are analysed using structural equation modelling. Interviews with five industry experts are further conducted to substantiate the results. Findings The results identified four major components of job satisfaction, namely, “job content”, “resource adequacy”, “work context” and “the personality and competence of jobholders”. The analysis also found that “technical requirement” and “split incentive” condition of green construction projects, “the expertise and awareness of PMs” and “demand and support from stakeholders” has significant impacts on PMs’ job satisfaction. Furthermore, this study developed eight strategies to improve PMs’ job satisfaction, including “increase recognition opportunities for PMs”, “government incentives and financial support” and “introductory and training courses on green construction legislation and processes”. Originality/value The findings assist construction companies in formulating measures to improve the job satisfaction and performance of PMs in green construction projects.

Green Construction

To respond to continuing global warming and rising environmental awareness, owners in the construction industry, a leading industry worldwide, must possess a greater awareness of energy- saving and carbon reduction construction products and their corporate social responsibilities. Construction industry owners are frequently required to focus on profit as the primary goal of projects for corporate sustainability. This study examined the effects on energy saving and carbon reduction efforts on the use of green construction elements in existing construction projects. The analysis results revealed that applying energy-saving and carbon reduction construction elements improves sales prices and rates substantially, even though it raises construction costs. In response to the evolution of green technology and the increase in consumer environmental awareness, future construction projects should increase the application of new energy-saving and carbon reduction construction materials. The results of this study provide a reference to construction industry owners implementing green construction materials.

And Performance

Over the last few years, the green building movement in Singapore has leaped bountifully. While environmental sustainability for greener construction has been emphasized, rare research has been conducted to analyze performance of green construction projects. As a result, this study aims to address schedule performance of green building construction projects and to provide some recommendations that may improve the targeted performance. To achieve this objective, a questionnaire was developed and the responses from 30 companies were analysed, and interviews with 6 project managers were conducted to further supplement and substantiate the survey results. The analysis reported that green building projects required an average of 8% more time than traditional building projects of similar size and characteristics. In addition, on average, these projects were delayed by 4.8% when compared with their as-planned schedules. Lastly, a list of recommendations was also introduced, aiming to ameliorate the schedule performance. This study will offer a benchmark for the industry to gauge the overall duration and performance of green building construction projects.

Green Construction

There are growing calls for construction site activities to be carried out in a sustainable manner. The reason for these calls is not far-fetched in view of the enormous impact such construction activities have on the natural environment. The objective of this study is to examine the effects of green construction site practices on environmental performance of construction projects in Nigeria. The effects of three green construction site practices namely waste management, materials management and energy management on environmental performance were analysed. 168 questionnaires were administered to site managers and project managers from “class A” contractors. The data were analysed using partial least squares-structural equation modelling. The results indicate that waste management has an insignificant impact on environmental performance, while materials management and energy management have positive effects on environmental performance. The results imply that not all sustainable construction site practices lead towards the attainment of environmental performance. The study has both theoretical and practical implication that helps policy makers and contractors to better understand the relationships that exists between these variables of sustainable construction site practices as well as environmental performance. This is essential in order to come out with a better plan for their projects and formulation of appropriate policies.
