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...

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...
