Heating, ventilation, and air conditioning (HVAC) systems can consume a large percentage of the energy used in a typical building. Intelligent building automation systems (BAS) are widely deployed to enable more efficient HVAC utilization, thus reducing the energy consumed. Enhanced data requires distributed sensing. We propose an instrumentation system for a low-cost, over-the-top efficiency monitor using the open-source hardware design to enable rapid deployment and live monitoring of temperature within zones such as rooms. This enables evaluation of HVAC system efficiency, and building parameter monitoring in that room. This paper presents our HVAC, thermal, and building parameter monitoring system design and considerations using an open-source hardware approach for fast customizations. We show results of monitoring two buildings including distributed sensing within rooms, and discuss intelligence gathered through use of this system as a precursor towards a fully automated efficiency evaluation and measurement.
