Virtual Surface Temperature Sensor For Multi-Zone Commercial Buildings, Yuebin Yu, Denchai Woradechjumroen, Daihong Yu

Architectural Engineering -- Faculty Publications

Multi-zone structure is commonly used in small commercial office buildings, retail stores and supermarket. While there is no adjacent wall between the zones, the impact of a neighbor zone on the current zone can be approximated and analyzed through the application of virtual walls. It is critical to accurately estimate the virtual wall surface temperature in order to evaluate the model uncertainty and apply improved supervisory control on multiple rooftop air-conditioning units (RTUs). We propose an innovative virtual surface temperature sensor based on system-identification to solve this challenge. The validation of the virtual temperature model is processed by the three ...

The Influence Of National Culture On Effectiveness Of Safety Trainings During Postdisaster Reconstruction, Behzad Esmaeili, Kevin Grosskopf, Amy Javernick-Will 2014 University of Nebraska - Lincoln

The Influence Of National Culture On Effectiveness Of Safety Trainings During Postdisaster Reconstruction, Behzad Esmaeili, Kevin Grosskopf, Amy Javernick-Will

Architectural Engineering -- Faculty Publications

Non-English speaking workers constitute a disproportionately high number of workers involved in postdisaster reconstruction. Additionally, the rate of fatality among these workers is higher than the industry average. Research shows this population is more prone to unsafe behaviors in the working environment, conceivably because many of these workers are sent into the field prior to any formalized training. Recent studies show that the native culture of construction workers can impact risk-taking behavior. While numerous researchers have attempted to develop training materials for Hispanic workers, the number of studies that consider the impact of native culture on safety behavior is minimal ...

Group-Work: Does It Have To Be That Bad?, Anthony Williams, L Henry, R Tucker, N Abassi

Administration and Research Conference Papers

Many accreditation bodies and universities require the graduate attribute of “an ability to work in teams” or to “effectively collaborate”. Students invariably dislike working in groups maintaining that “malingerers ride on the back” of those students who work hard and contribute effectively to the outcomes of the group or team. This is the context in which an ALTC/OLT project was established, the project is to consider ways of enhancing group-work in Architecture and design related disciplines. The project has identified the issues associated with group-work, from the perspective of student and lecturer, and has begun to develop strategies to ...


Linking Effective Whole Life Cycle Cost Data To Parametric Building Information Models Using Bim Technologies, Dermot Kehily, Trevor Woods, Fiacra P. McDonnell 2013 Technological University Dublin

Linking Effective Whole Life Cycle Cost Data To Parametric Building Information Models Using Bim Technologies, Dermot Kehily, Trevor Woods, Fiacra P. Mcdonnell

Conference papers

Abstract ̶ This paper demonstrates the capabilities of BIM (Building Information Modeling) in leveraging Whole Life Cycle Cost (WLCC) data requirements to perform WLCC calculations and produce WLLC estimates. The research determines the extent to which WLCC data, such as time, interest rates, escalation rates and real costs can be attached to parametric BIM data to be used effectively to create speedier and more accurate real-time WLLC analysis. Without incorporating WLCC data in the BIM, a complete picture of a construction project’s WLCC cannot be formed from the default outputs of the model. BIM 5D applications such as CostX utilise ...
