EnergyIQ v Portfolio Manager

EnergyIQ and Portfolio Manager have unique and complimentary use cases.

Portfolio Manager supports whole-building energy and water benchmarking, and provides a score that may lead to the attainment of an EnergyStar rating for high performance.  Portfolio Manager is targeted at existing non-residential and multifamily buildings.

EnergyIQ supports whole-building as well as end-use level benchmarking, with user-determined definition of peer groups.  These results are coupled with a detailed list of candidate energy efficiency upgrades. EnergyIQ is targeted at existing non-residential buildings, but is also used as a tool to inform the design process for new buildings

Thanks to Portfolio Manager's APIs, EnergyIQ users can import data they have previously entered in Portfolio Manager and conduct deeper benchmarking.
