Abstract

A method for monitoring and controlling an environment of an internal space including: providing conditioned air to the internal space using a heating, ventilation, and air conditioning (HVAC) system; detecting one or more environmental parameters within the internal space using at least one sensor; receiving a report request from an individual through a computer application of a computing device, the report request includes a focus area selection that selects one or more focus areas, wherein the one or more focus areas include at least one of an indoor air quality, a thermal comfort, or an airborne transmission; generating a performance report for the focus area based on at least the environmental parameters and specifications of the HVAC system, the performance report evaluating at least a performance of the HVAC system; and displaying the performance report on the computing device.

Claims (68)

1. A method for monitoring and controlling an environment of an internal space, the method comprising:

providing conditioned air to the internal space using a heating, ventilation, and air conditioning (HVAC) system;

detecting one or more environmental parameters within the internal space using at least one sensor;

receiving a report request from an individual through a computer application of a computing device, the report request including a focus area selection that selects one or more focus areas, wherein the one or more focus areas include at least one of an indoor air quality, a thermal comfort, or an airborne transmission;

generating a performance report for the focus area based on at least the environmental parameters and specifications of the HVAC system, the performance report evaluating at least a performance of the HVAC system; and

displaying the performance report on the computing device;

wherein generating the performance report for the focus area further comprises:

determining a performance score for each of the one or more focus areas based on at least the environmental parameters and the specifications of the HVAC system, wherein the performance score indicates how successful the HVAC system is at maintaining indoor air quality, thermal comfort and airborne transmission;

comparing the performance score to a threshold performance score; and

adjusting the HVAC system if the performance score is below the threshold performance score.

2. The method of claim 1 , further comprising:

cleaning air within the internal space using one or more portable air-cleaners,

wherein the performance report evaluates at least a performance of the HVAC system and a performance of the one or more portable air-cleaners.

3. The method of claim 1 , further comprising:

disinfecting air within the internal space using one or more disinfection and purification devices,

wherein the performance report evaluates at least a performance of the HVAC system and a performance of the one or more disinfection and purification devices.

4. The method of claim 1 , wherein adjusting the HVAC system comprises:

increasing outdoor air flow into the internal space through an external vent.

5. The method of claim 1 , wherein adjusting the HVAC system comprises:

increasing a detection frequency of the at least one sensor.

6. The method of claim 1 , wherein adjusting the HVAC system comprises:

activating or adjusting portable air-cleaners.

7. The method of claim 1 , wherein adjusting the HVAC system comprises:

activating or adjusting disinfection and purification devices.

8. The method of claim 1 , wherein adjusting the HVAC system comprises:

adjusting or changing a filter of the HVAC system.

9. The method of claim 1 , wherein adjusting the HVAC system comprises:

adjusting or activating a damper of the HVAC system.

10. The method of claim 1 , wherein adjusting the HVAC system comprises:

adjusting or activating a biological management device of the HVAC system.

11. The method of claim 1 , wherein adjusting the HVAC system comprises:

adjusting or activating an odor and chemical pollution management device of the HVAC system.

12. The method of claim 1 , wherein generating the performance report for the focus area further comprises:

transmitting instructions to the individual via the computer application to perform a maintenance action if the performance score is below the threshold performance score.

13. The method of claim 1 , wherein generating the performance report for the focus area further comprises:

determining a performance score for indoor air quality based on at least the environmental parameters and the specifications of the HVAC system,

wherein the environmental parameters include at least one of carbon dioxide concentration (CO 2 ), volatile organic compounds (VOC), particulate matter, and outside air flow level, and

wherein the specifications of the HVAC system include at least one of a type of outdoor air and return air filters, filter maintenance and management details, portable air-cleaner details, air cleaning technology, disinfection and purification devices, and maintenance practices for the HVAC system and associated components.

14. The method of claim 1 , wherein generating a performance report for the focus area further comprises:

determining a performance score for thermal comfort based on at least the environmental parameters and the specifications of the HVAC system,

wherein the environmental parameters include at least one of average temperature, relative humidity, and temperature control, and

wherein the specifications of the HVAC system include at least one of a number of thermostats per zone, a temperature control, and temperature and humidity monitoring and displays.

15. The method of claim 1 , wherein generating the performance report for the focus area further comprises:

determining a performance score for airborne transmission based on at least the environmental parameters and the specifications of the HVAC system,

wherein the environmental parameters include at least one of a room occupancy, a building occupancy, and air change rate in the internal space, and

wherein the specifications of the HVAC system include at least one of a room size, a room usage, a building size, and a building usage.

16. An environmental monitoring and control system for monitoring and controlling an environment of an internal space, the environmental monitoring and control system comprising:

a processor; and

a memory comprising computer-executable instructions that, when executed by the processor, cause the processor to perform operations, the operations comprising:

providing conditioned air to the internal space using a heating, ventilation, and air conditioning (HVAC) system;

detecting one or more environmental parameters within the internal space using at least one sensor;

receiving a report request from an individual through a computer application of a computing device, the report request including a focus area selection that selects one or more focus areas, wherein the one or more focus areas include at least one of an indoor air quality, a thermal comfort, or an airborne transmission;

generating a performance report for the focus area based on at least the environmental parameters and specifications of the HVAC system, the performance report evaluating at least a performance of the HVAC system; and

displaying the performance report on the computing device;

wherein generating the performance report for the focus area further comprises:

determining a performance score for each of the one or more focus areas based on at least the environmental parameters and the specifications of the HVAC system, wherein the performance score indicates how successful the HVAC system is at maintaining indoor air quality, thermal comfort and airborne transmission;

comparing the performance score to a threshold performance score; and

adjusting the HVAC system if the performance score is below the threshold performance score.

17. A computer program product tangibly embodied on a non-transitory computer readable medium, the computer program product including instructions that, when executed by a processor, cause the processor to perform operations comprising:

providing conditioned air to the internal space using a heating, ventilation, and air conditioning (HVAC) system;

detecting one or more environmental parameters within the internal space using at least one sensor;

receiving a report request from an individual through a computer application of a computing device, the report request including a focus area selection that selects one or more focus areas, wherein the one or more focus areas include at least one of an indoor air quality, a thermal comfort, or an airborne transmission;

generating a performance report for the focus area based on at least the environmental parameters and specifications of the HVAC system, the performance report evaluating at least a performance of the HVAC system; and
