Data-Driven Benchmarking of Building Energy Efficiency Utilizing Statistical Frontier Models
(American Society of Civil Engineers, 2014)Frontier methods quantify the energy efficiency of buildings by forming an efficient frontier (best-practice technology) and by comparing all buildings against that frontier. Because energy consumption fluctuates over time, ... -
Demonstrating the Impact of the Occupant on Building Performance
(American Society of Civil Engineers, 2014)Designers often cite uncertain occupant behavior as a potential obstacle to high performing buildings. However, little research has been done to characterize the nature and extent of the potential impact of the occupant ... -
Shuffled Frog-Leaping Model for Solving Time-Cost-Resource Optimization Problems in Construction Project Planning
(American Society of Civil Engineers, 2015)Time-cost-resources usage variation trade-off analysis is one of the most challenging tasks of construction project planners. Project planners face complicated multivariate, time-cost-resource optimization (TCRO) problems, ... -
Framework to Evaluate Energy-Saving Potential from Occupancy Interventions in Typical Commercial Buildings in the United States
(American Society of Civil Engineers, 2014)Occupancy-focused interventions to reduce building energy use have been shown to be effective but often result in unsustained energy reductions. In addition, these interventions have rarely been applied to commercial ... -
Short-Term Traffic Volume Prediction for Sustainable Transportation in an Urban Area
(American Society of Civil Engineers, 2015)Accurate short-term traffic volume prediction is essential for the realization of sustainable transportation as providing traffic information is widely known as an effective way to alleviate congestion. In practice, ... -
GIS-Based System for Sight Distance Analysis of Highways
(American Society of Civil Engineers, 2014)Analyzing the distance visible to a driver on a highway is important for traffic safety, especially in manoeuvres such as emergency stops, when passing another vehicle, or when vehicles cross at intersections. Software ... -
Impact of Social Network Type and Structure on Modeling Normative Energy Use Behavior Interventions
(American Society of Civil Engineers, 2014)Occupant behavior has a substantial impact on the total energy consumption in buildings. To reduce consumption much work has been done investigating behavioral energy-use interventions (e.g., feedback). Being able to ... -
Backcalculation of Flexible Pavement Structural Properties Using a Restart Covariance Matrix Adaptation Evolution Strategy
(American Society of Civil Engineers, 2015)Monitoring structural integrity of pavements is a central task of pavement management systems toward needs analysis and the subsequent design, prioritization, and optimization of pavement maintenance and rehabilitation ... -
Real-Time Traffic Density Estimation without Reliable Side Road Data
(American Society of Civil Engineers, 2015)One of the most popular intelligent transportation systems (ITS) applications is to provide real-time road traffic congestion information to the users. Traffic density is a major congestion indicator, and because its ... -
Potential of Time-of-Flight Range Imaging for Object Identification and Manipulation in Construction
(American Society of Civil Engineers, 2014)In this paper, we examine the potential of a range camera in construction material sorting applications. By utilizing the depth information from a time-of-flight (TOF) camera, we identify and classify objects placed on a ... -
Process and Future of Data Integration within the European Earthquake Engineering Laboratories
(American Society of Civil Engineers, 2014)In common with many scientific disciplines, earthquake engineering research is increasingly focusing on large international collaborations to address complex problems. Data integration is a key requirement to facilitate ... -
