The arpa-e SENSOR [1] program is working on several technologies for people counting for sake of doing Demand Controlled Ventilation (DCV)[2]. People counting is part of the ASHRAE 62.1 calculation [3] for demand controlled ventilation. Also, simple N>0 occupancy counting is useful for home HVAC system setbacks.
I sat in an ASHRAE technical session presentation the other day about the program. All of the technology goals intend for the people count results to be anonymous, and for the technology to be "open source."
Cost goals are <$0.06/ft^2 for residential and <0.08$/ft^2 for commercial systems.
