## Abstract

A building management system for monitoring and controlling HVAC parameters in a building includes one or more processing circuits configured to initialize a predictive model for predicting temperature, pressure, and humidity within a target area and an adjacent area of the building, receive target area data from a target area sensor array configured to measure temperature, pressure, and humidity of the target area, receive adjacent area data from an adjacent area sensor array configured to measure temperature, pressure, and humidity of the adjacent area, execute the predictive model based on the target area data and the adjacent area data to generate a prediction of future temperature, pressure, and humidity within the target area, and control operation of HVAC equipment to maintain the temperature, pressure, and humidity of the target area within a compliance standard.

## Claims

one or more processing circuits comprising one or more memory devices coupled to one or more processors, the one or more memory devices configured to store instructions thereon that, when executed by the one or more processors, cause the one or more processors to:
initialize one or more predictive models for predicting temperature and pressure within a target area and an adjacent area of the building,
receive target area data from a target area sensor configured to measure temperature and/or pressure of the target area,
receive adjacent area data from an adjacent area sensor configured to measure temperature and/or pressure of the adjacent area,
execute the one or more predictive models, based on the adjacent area data, to generate a prediction of future temperature and pressure within the adjacent area,
execute the one or more predictive models, based on the target area data and the prediction of future temperature and pressure within the adjacent area, to generate a prediction of future temperature and pressure within the target area, and
control operation of HVAC equipment, based on the prediction of future temperature and pressure within the target area, to maintain the temperature and/or pressure of the target area within a compliance standard.

### Claim 2 (depends on 1)

receive updated target area data from the target area sensor,
receive updated adjacent area data from the adjacent area sensor, and
prior to executing the one or more predictive models, update the one or more predictive models based on the updated target area data and the updated adjacent area data.

### Claim 3 (depends on 1)

The BMS of claim 1, wherein the one or more memory devices are further configured to store instructions thereon that, when executed by the one or more processors, cause the one or more processors to:
