A Methdology for Baselining the Energy Use at Large Campus Utility Plants for the Purpose of Measuring Energy Savings from Energy Conservation Retrofits
(Texas A&M University, 1999)
The development of the energy services industry and the implementation of energy savings retrofits by energy services companies has increased the focus on the performance of energy saving retrofits. Energy savings measurement, ...
Whole-Building Commercial HVAC System Simulation for Use in Energy Consumption Fault Detection
(Energy Systems Laboratory, 2007-05)
Numerous fault detection and diagnostic system techniques
have been developed for HVAC systems, but most focus
on detecting faults at the component level, for example, air handling
units or variable air volume boxes. ...
The Effect of a 90 Degree Elbow on the Accuracy of Liquid Flow Measurement with an Insertion Flowmeter
(Energy Systems Laboratory, 2000-08)
To quantify the measurement error of slow meters in the developing length, simulation model development, local velocity measurements, flowmeters test, and regression model development were carried out for 10.2 cm, 15.2 cm, ...
Development and Validation of a Computer Model for Energy-Efficient Shaded Fenestration Design
(Texas A&M University, 2000-05)
The goal of this study is to develop and validate a computerized model for an energy efficient fenestration system that can easily be incorporated into the architectural design process. This model is for the thermal ...
Monitoring the Performance of a Residential Central Air Conditioner under Reduced Evaporator Air Flow on a Test Bench
(Texas A&M University, 1992-11)
This report presents results from degraded performance measurements of a residential air conditioning system operating under reduced evaporator air flow. Experiments were conducted using a R-22 three-ton split-type cooling ...
Aerosol Deposition in Transport Lines
(Texas A&M University, 1995-12)
Particle deposition in contraction fittings with half-angles of 12 degrees, 45 degrees, and 90 degrees; expansion fittings with half-angles of 3 degrees, 6 degrees, 12 degrees, 45 degrees, and 90 degrees; and ...
Development of Fourier Series and Artificial Neural Network Approaches to Model Hourly Energy Use in Commercial Buildings
(Texas A&M University, 1995-05)
This dissertation develops Fourier series and Artificial Neural Network (ANN) approaches to model hourly energy use in commercial buildings and illustrates application to data-screening.
The procedure for modeling hourly ...
An Expert System for the Analysis of Building Energy Consumption, Doctoral Disseration
(University of Colorado, 1986-07)
This work concludes six years of energy conservation studies performed for the University of Colorado Student Recreation Center.
The studies began late in 1980 when the University of Colorado Student Administrators asked ...
An Analysis of Grocery Store Energy Use
(Texas A&M University, 1993-12)
Approximately 3% of the United States' commercial building energy consumption is attributable to food sales facilities. Although this is one of the smallest consumption percentages, it is still significant, amounting to ...
A Methodology for In-Situ Calibration of Steam Boiler Instrumentation
(Texas A&M University, 1997)
This thesis presents a broadly useful diagnostic methodology to engineers and plant managers for finding the in-situ operating characteristics of power plant boilers when metered data is either missing or obviously erroneous. ...
