Abstract: Certain embodiments relate to systems and methods for monitoring and improving the efficiency by which systems maintain building environments. A building management system may analyze values observed by sensors and other devices and determine whether the observed values fall within a range. If the observed values do not fall within the range and the building's control system has not taken appropriate action to ensure that the observed values do fall within the range, the building may generate a floor plan specifying where the failure occurred. A building ranking system may rank a plurality of buildings based upon their relative efficiency. The building ranking system may determine each building's efficiency based on a set of parameters related to the building's energy usage that are normalized for weather, occupancy, and other external parameters.
