Rework in Building Information Modelling (BIM)-based construction projects have considerable implications for project timelines, costs, and efficiency. Despite the acknowledged potential of BIM, rework remains a significant and persistent issue, necessitating urgent attention. This study aims to model the relationship between BIM's key effect on re...

The adoption of smart technology in Building Information Modelling (BIM)-based construction projects faces significant challenges and opportunities. Concerns about job displacement and privacy invasion contrast with the potential for enhanced environmental and societal benefits. This study aims to identify the relationship between the key challenge...

As global energy consumption, climate change, and environmental degradation continue to escalate, the need for sustainable solutions has become more critical than ever. Passive cooling is emerging as a promising approach to improve energy efficiency in the built environment. This research investigates the potential of passive cooling in new buildin...

The role of technology in education is becoming increasingly important, and the introduction of advanced technology and AI is transforming the way we learn. Virtual reality (VR) is an effective technology that enhances student engagement and improves learning outcomes. However, the cost of implementing VR is a significant concern for educational in...

Small commercial buildings, or those comprising less than 50,000 square feet of floor area, represent 94% of U.S commercial buildings by count and consume approximately 8% of the nation’s primary energy; as such, they represent a largely unexploited opportunity for energy savings. Small commercial buildings also represent a large economic market—th...

Engineering schools have been unable to recruit and retain Native American students at the same rate as other students. Consequently, the Native American representation in engineering has been declining over the years in Arizona, even though the state ranks third in the number of degrees earned in the US by Native Americans. To understand the barri...

Building energy assessment is essential to accomplish the sustainable energy targets of new and present buildings. Retrofitting of the existing buildings by assessing them through energy models is the most prominent method. Studies revealed that there is still blank information about the building stocks, and these affect the valuation of building e...

Transportation sustainability is centered on being the linchpin to cultivate innovations and enhance safer environmental standards. The public and private agencies adopt sustainable practices integrating their policies in order to elevate sustainability performances. There is an advent need of developing a tool for quantifying the transportation po...

Geotagging is the process of labeling data and information with geographical identification metadata, and text mining refers to the process of deriving information from text through data analytics. Geotagging and text mining are used to mine rich sources of social media data, such as video, website, text, and Quick Response (QR) code. They have bee...

Buildings are the largest consumer of energy in the United States from various sectors that includes transportation, industry, commercial, and residential buildings. Leadership in Energy and Environmental Design (LEED) certification program, home energy rating system (HERS), and American Society of Heating, Refrigerating and Airconditioning Enginee...

Transportation systems facilitate the flow of goods and services globally, creating jobs and encouraging economic growth while generating negative impacts on the environment and society. Federal and state transportation agencies rely on sustainable practices to alleviate these impacts. While these practices are critical to lessen these negative imp...

The intimate relationship between energy consumption and climate change demands attention. More energy will be needed to run cooling systems if the annual global temperature continues to rise. The urban heat island would also increase the demand for cooling. As global energy demand continues to grow, the utility sector would face a continuous incre...

Commercial buildings’ consumption is driven by multiple factors that include occupancy, system and equipment efficiency, thermal heat transfer, equipment plug loads, maintenance and operational procedures, and outdoor and indoor temperatures. A modern building energy system can be viewed as a complex dynamical system that is interconnected and infl...

Wildfires are a major environmental hazard that causes fatalities greater than structural fire and other disasters. Computerized models have increased the possibilities of predictions that enhanced the firefighting capabilities in U.S. While predictive models are faster and accurate, it is still important to identify the right model for the data ty...

Purpose The purpose of this paper is to understand the corporate sustainability culture of contracting firms, particularly in the Midwest. Many of the local firms operate nationally. The local corporate culture influences their regional offices. Other than convenience, the firms are selected from Midwest since their headquarters are situated in Mid...

Energy efficiency is a critical element of building energy conservation. Energy Information Administration (EIA) and International Electrotechnical Commission (IEC) estimated that over 6% of electrical energy was lost during transmission and distribution. Sensing and tracking technologies, and data-mining offer new windows to better understanding t...

As the construction continue to be a leading industry in the number of injuries and fatalities annually, several organizations and agencies are working avidly to ensure the number of injuries and fatalities is minimized. The Occupational Safety and Health Administration (OSHA) is one such effort to assure safe and healthful working conditions for w...

There are many data mining and machine learning techniques to manage large sets of complex energy supply and demand data for building, organization and city. As the amount of data continues to grow, new data analysis methods are needed to address the increasing complexity. Using data from the energy loss between the supply (energy production source...

Previous studies in building energy assessment clearly state that to meet sustainable energy goals, existing buildings, as well as new buildings, will need to improve their energy efficiency. Thus, meeting energy goals relies on retrofitting existing buildings. Most building energy models are bottom-up engineering models, meaning these models calcu...

The estimation of energy demand (by power plants) has traditionally relied on historical energy use data for the region(s) that a plant produces for. Regression analysis, artificial neural network and Bayesian theory are the most common approaches for analysing these data. Such data and techniques do not generate reliable results. Consequently, exc...

Sustainable practices have become the cornerstone of the transportation sector and widely adopted by many states' transportation agencies. Sustainable practices have now become the edifice of the transportation sectors, but the adoption of such practices is not fast enough to overcome the ever-increasing global demand for resources. There are numer...

Sustainable practices have become the cornerstone of the transportation sector, and widely adopted by many states’ transportation agencies. The nerve center of the economic development today circles around resource utilization and energy use. The transportation sector is the bloodline of the U.S economy and sustainability of this sector affects the...

Climate change will affect the basic elements of life for people around the world, access to water, food production, health and the environment. Hundred of millions of people could suffer water shortages, hunger and coastal flooding as the world warms. A changing climate will have increasingly grave consequences for the world’s poorest, most vulner...
