This mode is suited for pattern classification. The advantage of a back-propagation learning algorithm is that it is simple to implement and computationally efficient due to the fact that its complexity is linear in the synaptic weights of the network. However, a major limitation of this algorithm is that the convergence is not always guaranteed and can be excruciatingly slow, particularly when the network topology is large. There are many ways that feed forward neural networks can be constructed.

They found that general regression neural networks and SVMs were more applicable to this problem compared to other models. Furthermore, SVM showed the best performance among all prediction models. The models were trained on the data of 59 buildings and tested on nine buildings. Liang and Du [LIA 07] presented a cost-effective fault detection and diagnosis method for HVAC systems by combining the physical model and a SVM. By using a four-layer SVM classifier, the normal condition and three possible faults can be recognized quickly and accurately with a small number of training samples.

Energy auditing evaluates the efficiency of all building components and systems that impact energy use. The audit process begins at the utility meters where the sources of energy coming into a building or facility are measured. Energy flow inputs and outputs for each fuel are then identified. These flows are measured and quantified into distinct functions or specific uses, then the function and performance of all building components and systems are evaluated. The efficiency of each of the functions is assessed, and energy and cost-saving opportunities are identified.
