This work presents a robust and computationally efficient algorithm for both whole-building and component-level energy fault detection and diagnosis (FDD). The algorithm is able to provide reliable estimation of multiple and simultaneous fault conditions, even in the presence of noisy and...

From a systems perspective, energy-efficient design should strive to minimize the energy and money required to provide the desired quantity and quality of illumination. A wide spectrum of technologies, design practices, and control strategies exists to increase lighting energy efficiency. We...

In spite of the recent explosive growth in the use of office and network equipment, there has been no recent study (until this one) that estimates in detail how much electricity is consumed by that equipment in the United States.

Energy edge (EE) was a research-oriented demonstration project that began in 1985; 28 buildings were constructed to use 30% less electricity than a hypothetical simulated baseline building. Average energy savings for 18 buildings evaluated with post-occupancy tuned simulation models were less at...
