A system and a method are proposed for sanitizing air in premises. The system comprises an air compressor for sucking and then compressing the air supposedly comprising noxious and/or allergenic small items up to a denaturing pressure. The system is provided with a controllable pressure tank for denaturing there-inside the mentioned small items supplied with the compressed air. The tank controllably receives the compressed air from the compressor, heats and maintains the compressed air within a denaturing temperature range and discharges the compressed sanitized air to the premises, so that the discharged sanitized air cools down while expanding.

A heating, ventilation, or air conditioning (HVAC) system for one or more building zones includes airside HVAC equipment that provide air to the one or more building zones and a controller. The controller obtains predictive models to predict values of a first control objective and a second control objective for the one or more building zones as a function of control decision variables for the airside HVAC equipment. The controller performs a Pareto optimization for a time period using the one or more predictive models to determine multiple sets of Pareto optimal values of the control decision variables and corresponding sets of Pareto optimal values of the first control objective and the second control objective for the time period. The controller operates the airside HVAC equipment to provide the air to the one or more building zones in accordance with a selected set of the Pareto optimal values.

Systems for providing heating, ventilation, and air conditioning (HVAC) in transit vehicles include one or more sanitizers. Sanitizers can include a pre-filter installed upstream of a filter, a filter including or coated with an anti-pathogen material, or a treatment dispenser providing a treatment including an anti-pathogen material to reduce pathogen risk and/or improve air quality within the transit vehicle. Methods for operating a transit HVAC system can include reducing pathogens. Pathogens can be reduced by one or more of filtering air passing through the transit HVAC system using a pre-filter, filtering the air passing through the transit HVAC system using a filter that is coated with or includes an anti-pathogen material, or providing a treatment including the anti-pathogen material to the air passing through the transit HVAC system. Systems can further be configured to provide air first to a driver section of the transit vehicle.
