Abstract

Claims (29)

1. A method in a building management system (BMS) performed by one or more processors, the method comprising:

receiving health risk data from a health agency, the health risk data indicating new cases of an infectious disease in a geographic area of a building and comprising an identification of the infectious disease in the geographic area of the building;

determining a building-specific health risk level comprising a probability of infection for at least one space in the building based on both (i) the health risk data for the geographic area of the building, a quanta generation rate for the infectious disease, and (ii) building-specific information comprising occupancy data for the building and a control strategy for the at least one space in the building comprising an outdoor air ventilation rate; and

controlling equipment to perform at least one of an air handling action or a disinfection action in the building based on the building-specific health risk level.

2. The method of claim 1 , wherein performing the air handling action comprises increasing an outdoor air ventilation rate in the space in the building.

3. The method of claim 1 , wherein performing the disinfection action comprises using disinfectant light to sanitize air circulated through the space in the building.

4. The method of claim 1 , wherein performing the disinfection action comprises performing air filtration at an air handling unit of the BMS.

5. The method of claim 1 , further comprising receiving a user input, wherein the user input comprises weightings indicating importance of health risk reduction relative to energy consumption.

6. The method of claim 1 , wherein the health agency is a national or international organization.

7. A building management system (BMS), the system comprising:

one or more processors; and

one or more computer-readable storage media having instructions stored thereon that, upon execution by the one or more processors, cause the one or more processors to implement operations comprising:

receiving health risk data from a health agency, the health risk data indicating new cases of an infectious disease in a geographic area of the building and comprising an identification of the infectious disease in the geographic area of the building;

determining a health risk level comprising a probability of infection for at least one space in the building based on both the health risk data, a quanta generation rate for the infectious disease, occupancy data for the building, and a control strategy for the at least one space in the building comprising an outdoor air ventilation rate; and

controlling equipment to perform at least one of an air handling action or a disinfection action in the building based on the health risk level.

8. The system of claim 7 , wherein the operations further comprise receiving a user input, wherein the user input comprises weightings indicating importance of health risk reduction relative to energy consumption.

9. The system of claim 7 , wherein performing the air handling action comprises increasing an outdoor air ventilation rate in the space in the building.

10. The system of claim 7 , wherein performing the disinfection action comprises at least one of using disinfectant light to sanitize air circulated through the space in the building, performing air filtration at an air handling unit of the BMS, providing ozone in the space in the building, or using a humidifier to add disinfectant to air in the space in the building.

11. The system of claim 7 , wherein the health agency is a national or international organization.

12. The system of claim 7 , wherein determining the health risk level comprises determining whether any individuals in the building have been infected with the infectious disease.

13. A method in a building management system (BMS) performed by one or more processors, the method comprising:

receiving health risk data from a health agency, the health risk data indicating new cases of an infectious disease in a geographic area of a building and comprising an identification of the infectious disease in the geographic area of the building;

receiving occupant data for one or more individuals in the building;

determining a health risk level comprising a probability of infection for at least one space in the building based on the health risk data, a quanta generation rate for the infectious disease, the occupant data comprising occupancy data for the building, and a control strategy for the at least one space in the building comprising an outdoor air ventilation rate; and

controlling equipment to perform at least one of an air handling action or a disinfection action in the building based on the health risk level.

14. The method of claim 13 , wherein receiving the occupant data comprises receiving biometric data from one or more wearable devices associated with the one or more individuals in the building and receiving health record data regarding the infectious disease for the one or more individuals in the building.

15. The method of claim 13 , wherein performing the air handling action comprises increasing an outdoor air ventilation rate in the space in the building, and wherein performing the disinfection action comprises at least one of using disinfectant light to sanitize air circulated through the space in the building or performing air filtration at an air handling unit of the BMS.

16. The method of claim 13 , wherein the health agency is a national or international organization.

17. The method of claim 13 , further comprising receiving a user input, wherein the user input comprises a first weight indicating an importance to reduce health risks, and a second weight indicating an importance to reduce energy cost.
