The computing system is programmed to record a warning when the sensor measurements are out of compliance relative to a compliance standard for longer than a warning delay time, generate an alert in response to a combination of recording the warning and a non-improving trend of the sensor measurements, and in response a combination of recording the warning and an improving trend of the sensor measurements, suppress the alert until the improving trend continues with the sensor measurements out of compliance for greater than an alert delay time. ## Claims ### Claim 1 A compliance system for a critical environment comprising: at least one sensor configured to output sensor measurements relating to at least one environmental condition of the critical environment; a computing system programmed to: record a warning when the sensor measurements are out of compliance relative to a compliance standard for longer than a warning delay time; in response to a combination of recording the warning and a non-improving trend of the sensor measurements, generate an alert; in response a combination of recording the warning and an improving trend of the sensor measurements: suppress the alert until the improving trend continues with the sensor measurements out of compliance for greater than an alert delay time; and generate the alert upon the improving trend continuing with the sensor measurements out of compliance for greater than the alert delay time. ### Claim 2 (depends on 1) The compliance system of claim 1, wherein the computing system is programmed to classify the sensor measurements as having the improving trend or the non-improving trend by calculating a derivative of the sensor measurements. ### Claim 3 (depends on 1) The compliance system of claim 1, wherein the computing system is programmed to classify the sensor measurements as having the improving trend or the non-improving trend by calculating an integral of a difference between the sensor measurements and the compliance standard. ### Claim 4 (depends on 1) The compliance system of claim 1, wherein the computing system is programmed to classify the sensor measurements as having the improving trend or the non-improving trend by: determining a direction of change of the sensor measurements over time; identifying the improving trend when the direction of change is toward the compliance standard; and identifying the non-improving trend when the direction of change is away from the compliance standard or when the sensor measurements are not changing over time. ### Claim 5 (depends on 1) The compliance system of claim 1, wherein the computing system is programmed to adjust the warning delay time or the alert delay time based on a magnitude of a deviation of the sensor measurements from the compliance standard. ### Claim 6 (depends on 1) The compliance system of claim 1, further comprising a display, wherein the computing system is configured to generate the alert by causing a notification to be presented on the display, wherein the computing system is programmed to abstain from causing the notification to be presented in response to the warning until the alert is generated. ### Claim 7 (depends on 6) The compliance system of claim 6, wherein the computing system is configured to automatically populate a compliance report with the warning. ### Claim 8 (depends on 1) The compliance system of claim 1, wherein the critical environment is an operating room of a healthcare facility and the sensor measurements represent temperature, pressure, and humidity of the operating room. ### Claim 9 (depends on 1) The compliance system of claim 1, wherein the critical environment is a laboratory. ### Claim 10 (depends on 1) The compliance system of claim 1, wherein the computing system is programmed to automatically determine a root cause in response to the alert and automatically generate a work order to resolve the root cause. ### Claim 11 (depends on 1) The compliance system of claim 1, wherein the computing system is programmed to automatically determine a root cause in response to the alert and cause a unit of building equipment to change operations to resolve the root cause. ### Claim 12 (depends on 1) The compliance system of claim 1, wherein the computing system is programmed to record the warning when the sensor measurements are out of compliance relative to the compliance standard for longer than the warning delay time by: incrementing a timer in response to the sensor measurements being out of compliance; decrementing the timer in response to the sensor measurements being in compliance; and comparing the timer to the warning delay time. ### Claim 13 A method for reducing alarm noise in a monitoring system for compliance standards for temperature, pressure, or humidity of a healthcare facility, comprising: collecting, by at least one sensor, sensor measurements relating to at least one of the temperature, pressure, and humidity of the healthcare facility; recording a warning when the sensor measurements are out of compliance relative to a compliance standard for longer than a warning delay time; in response to a combination of recording the warning and a non-improving trend of the sensor measurements, generating an alert; in response a combination of recording the warning and an improving trend of the sensor measurements: suppressing the alert until the improving trend continues with the sensor measurements out of compliance for greater than an alert delay time; and generating the alert upon the improving trend continuing with the sensor measurements out of compliance for greater than the alert delay time. ### Claim 14 (depends on 13) The method of claim 13, comprising classifying the sensor measurements as having the improving trend or the non-improving trend by calculating an integral of a difference between the sensor measurements and the compliance standard or by calculating a derivative of the difference. ### Claim 15 (depends on 13) The method of claim 13, comprising classifying the sensor measurements as having the improving trend or the non-improving trend by: determining a direction of change of the sensor measurements over time; identifying the improving trend when the direction of change is toward the compliance standard; and identifying the non-improving trend when the direction of change is away from the compliance standard or when the sensor measurements are not changing over time. ### Claim 16 (depends on 13) The method of claim 13, comprising: abstaining from causing a notification be pushed to a user in response to the warning until the alert is generated; and causing the notification to be pushed to the user in response to generating the alert. ### Claim 17 (depends on 16) The method of claim 16, comprising automatically populating a compliance report with the warning. ### Claim 18 One or more non-transitory computer-readable media storing program instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising: recording a warning when sensor measurements relating to at least one environmental condition of a critical environment are out of compliance relative to a compliance standard for longer than a warning delay time; in response to a combination of recording the warning and a non-improving trend of the sensor measurements, generating an alert; in response a combination of recording the warning and an improving trend of the sensor measurements: suppressing the alert until the improving trend continues with the sensor measurements out of compliance for greater than an alert delay time; and generating the alert upon the improving trend continuing with the sensor measurements out of compliance for greater than the alert delay time. ### Claim 19 (depends on 18) The one or more non-transitory computer-readable media of claim 18, wherein the operations further comprise: abstaining from causing a notification be pushed to a display device in response to the warning until the alert is generated; causing the notification to be pushed to the display device in response to generating the alert; and automatically populating a compliance report with the warning. ### Claim 20 (depends on 18) The one or more non-transitory computer-readable media of claim 18, wherein the critical environment is an operating room of a healthcare facility and the sensor measurements represent temperature, pressure, and humidity of the operating room.
