Abstract
Disclosed is a system and method for managing the comfort of building occupants. The system utilizes a model-based approach for targeting occupant comfort levels. The system allows for voting input from building occupants regarding their respective comfort. Additionally, the system provides a user interface to gather occupant input and use said input as a parameter in a comfort model.
Claims19
An environmental control system, comprising:
- a plurality of occupant proxies, one or more non-human asset proxies, a comfort model, a meta-proxy, and an output function, wherein:
- the comfort model comprises a mathematical equation of human comfort, the mathematical equation comprising or derived from predicted mean vote (“PMV”) and predicted percentage of dissatisfied (“PPD”);
- the plurality of occupant proxies each comprise a comfort state of an individual occupant;
- the one or more non-human asset proxies each comprise a comfort model for a non-human asset in or proximate to a building, the comfort model for the non-human asset comprising a mathematical equation of building asset comfort for the building, the mathematical equation of building asset comfort comprising one or more of an equipment environmental operation model, a metallic rust model, a building material moisture capacity model, a building material mold potential model, an animal comfort model, a plant health model, and a water freeze model;
- the comfort state comprises a function of the comfort model;
- the meta-proxy comprises a combined function of the plurality of occupant proxies and the one or more non-human asset proxies;
- the output function comprises a building system control path for the building as a function of the meta-proxy;
- and
- the output function receives the meta-proxy as an input and provides the building system control path as a path-based control output to control a building system for the building based on a combination of both the plurality of occupant proxies and the one or more non-human asset proxies.
An electronic device or network of electronic devices comprising:
- a motion sensor component;
- at least one memory;
- and
- one or more processors operatively coupled to the motion sensor component and one or more processors operatively coupled to the at least one memory, where the processors are configured to execute program code stored in the at least one memory to:
- receive motion measurements obtained with the motion sensor component;
- analyze the motion measurements to identify a degree of metabolic energy generated at least in part by the measured motion;
- compute a comfort of a mobile user via a human comfort model, the human comfort model comprising a mathematical equation of human comfort, the mathematical equation comprising or derived from predicted mean vote (“PMV”) and predicted percentage of dissatisfied (“PPD”);
- compute, using an output function that receives a meta-proxy as an input, the meta-proxy comprising an occupant proxy for the mobile user based on the computed comfort and a non-human asset proxy for a non-human asset, a control offset between a combination of the comfort of the mobile user and a comfort for the non-human asset, and current environmental conditions, thus generating a control path as a path-based control output to control an environmental control system, the non-human asset proxy comprising a comfort model for a non-human asset in or proximate to a building, the comfort model for the non-human asset comprising a mathematical equation of building asset comfort, the mathematical equation of building asset comfort comprising one or more of an equipment environmental operation model, a metallic rust model, a building material moisture capacity model, a building material mold potential model, an animal comfort model, a plant health model, and a water freeze model;
- and
- transmit the control path to the environmental control system.
A system for a user interface representation of human comfort preferences in a human comfort model proxy driven environmental control system, the system comprising:
- a computing device with a display;
- an application interface;
- objects in a graphical user interface, of the type in which representations of objects stored in a memory are displayed to a user on the display, wherein the objects comprise abstractions of comfort model parameters representing one or more human factors in the human comfort model proxy and one or more non-human factors in a non-human asset proxy for a non-human asset in or proximate to a building associated with the environmental control system;
- and
- whereby:
- the comfort model parameters, in conjunction with environmental parameters, are used to calculate the human comfort model proxy, the human comfort model proxy comprising a mathematical equation of human comfort, the mathematical equation comprising or derived from predicted mean vote (“PMV”) and predicted percentage of dissatisfied (“PPD”);
- and
- the human comfort model proxy and the non-human asset proxy are used as input into an output function to compute a control path as a path-based control output of the output function to control the environmental control system, the non-human asset proxy comprising a comfort model for the non-human asset in or proximate to the building, the comfort model for the non-human asset comprising a mathematical equation of building asset comfort, the mathematical equation of building asset comfort comprising one or more of an equipment environmental operation model, a metallic rust model, a building material moisture capacity model, a building material mold potential model, an animal comfort model, a plant health model, and a water freeze model.
