Abstract: A current load on the AHU used to maintain one or more comfort conditions in the building space is determined, along with a remaining load capacity. A maximum additional fresh air ventilation air flow that could be admitted and conditioned using the remaining load capacity of the AHU such that the AHU could still maintain the one or more comfort conditions in the building space is determined. A fresh air intake damper position for the fresh air intake damper that increases the fresh air ventilation air flow through the fresh air intake damper by a fraction of the maximum additional fresh air ventilation air flow is determined. The fraction may be based at least in part on one or more of a temperature factor and an air quality factor. The fresh air intake damper is set to the determined fresh air intake damper position.

Abstract: Gas meter data validation for a Meter Data Management (MDM) system including a communications network connecting gas data downloading device(s) receiving gas meter data including corrected gas volume data (CGVD) and state variable(s) data from primary gas meter(s) to the system, and a server implementing gas data validation (GDV) software. The GDV software performs data validation checks on the gas meter data including the CGVD to identify erroneous CGVD, and if a data validation check fails, performs a root cause analysis to diagnose a root cause involved in the erroneous CGVD using the data validation check and additional information regarding the communications network and primary gas meter, and error resolution depending on the root cause during the time interval including (i) calculating a revised CGVD after refetching uncorrected GVD and the state variable data or (ii) estimating the state variable data and calculating the revised CGVD therefrom.

Abstract: A method for controlling an Air Handling Unit (AHU) of an HVAC (Heating, Ventilating and Air Conditioning) system servicing a building space of a building includes determining when there is an elevated pathogen transmission risk in the building space. In response to determining that there is an elevated pathogen transmission risk in the building space, the AHU is controlled to adjust operation of the AHU to alleviate the elevated pathogen transmission risk.
