The present disclosure relates to commissioning buildings. More specifically, to setting up sensors in a building and understanding the relationships between devices in the building such that the building can commission itself.
Building commissioning is the process of turning on a new building and determining that all the systems work as designed. Commissioning is complex enough that there are a great deal of resources devoted to it—seminars, conferences, whole careers. Typically, heating, ventilation, and air conditioning (HVAC) systems of a building are tested to see if they are wired correctly. These systems may also be balanced, to check that they run as expected within the building structure. This can be a very time-consuming process, as different areas of the building influence each other. For example, if two sensors in two close zones have been mistakenly flipped, the sensor readings may be close enough to what is assumed to be correct that it is not until the building has already been moved into that the error is noticed, at which point it is very difficult to fix; as the fix may involve tearing out walls to get to underlying wiring. Generally, there have been studies exploring the concept of automatic commissioning, however, the methods used to date have typically required an occupancy-free training period, during which the building is subjected to an artificial test regime, which limits the potential for retro-commissioning, or continuous commissioning. Being able to prove that a building is commissioned correctly is important in getting owners to sign off on construction, can lead to energy savings, and, if done with enough provability, can lead to energy and other sorts of discounts from local and state governments, and power companies.
This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description section. This summary does not identify required or essential features of the claimed subject matter. The innovation is defined with claims, and to the extent this Summary conflicts with the claims, the claims should prevail.

Disclosed below are representative embodiments of methods, computer-readable media, and systems having particular applicability to automated commissioning. Described embodiments implement one or more of the described technologies.
Various alternatives to the implementations described herein are possible. For example, embodiments described with reference to flowchart diagrams can be altered, such as, for example, by changing the ordering of stages shown in the flowcharts, or by repeating or omitting certain stages.
When originally building a structure, the creation process can include designing the structure and designing and implementing the controllers; teaching the controllers about the devices that will be attached to them; and attaching the building devices to the controllers, such that the building itself understands what is necessary for the commission process. The commissioning process then can be done automatically and systematically. As the process is largely automatic, a full history of the commissioning can be created, including a history of each individual device. Once a building has been commissioned, it can be validated such that the quality of commissioning can be shown to outside entities, such as power companies and governmental entities. Such structures can then prove that they can qualify for various incentives.
The technical character of embodiments described herein will be apparent to one of ordinary skill in the art, and will also be apparent in several ways to a wide range of attentive readers. Some embodiments address technical activities that are rooted in computing technology, such as more quickly and efficiently running automated commissioning systems. This is useful as the commissioning process takes much less time; there is a record of what devices have been commissioned, when they were last commissioned, and what the results were. This historical information is invaluable when recommissioning a building, as the previously used pieces of paper may have been lost, the engineers who previously commissioned the space may have changed jobs, etc. Further, when a single device is added and must be commissioned, it can easily be done without closing down the entire building. Other advantages based on the technical characteristics of the teachings will also be apparent to one of skill from the description provided.
The memory 120 can be any appropriate volatile or non-volatile storage subsystem. For example, the memory may be partially or wholly external, may be volatile memory, e.g., static memory cells, as in FPGAs and some CPLDs; or non-volatile memory, e.g., FLASH memory, as in some CPLDs, or in any other appropriate type of memory cell. The memory itself may have within it a model of the physical space 130. This physical space model may be a digital twin, in that the model understands the physical space at a deep level; understanding, for example, the physics of the structure itself, so that it understands how state, such as temperature, diffuses through the structure. It may also understand the location within the physical structure of devices that change state (such as HVAC equipment, lighting, security equipment, etc.) and the nature of the devices at a physics level, such that the projected interaction between the physical space and devices is understood. For example, when a heater is turned on, the physical space model may understand how quickly the heater should heat up, how the heat moves through the building, how the heat from the heater should affect sensors in the physical space, etc.
Storage 165 may also be included. The storage 165 may be removable or non-removable, and includes magnetic disks, magnetic tapes or cassettes, CD-ROMs, CD-RWs, DVDs, flash drives, or any other medium which can be used to store information and which can be accessed within the computing environment 100. The storage 165 stores instructions for the software 185 to implement methods used for automatic commissioning.
At least one of the controller(s) has an input/output device 155. The input/output device 155 is any sort known to those of skill in the art that allows human/computer interaction to occur, such as some combination of a computer screen, a printer, a touchscreen, a mouse, a screen, a keyboard, a printer, etc. The computer controller may also have one or more communication connections 160. These communication connections may be wired networks, wireless networks, and other types of communication connections as known by those of skill in the art.
A controller also has a number of devices 135, 150 associated with it. These devices may be any sort of device that can connect to a controller in a building, as known to those of skill in the art. These may include HVAC equipment, security equipment, entertainment equipment, irrigation equipment, printers, and so on. These devices may pass information from a specific device to the controller and may pass information from the controller to the device. For example, a controller could tell a device to turn on, the device could send the controller error messages, etc. Some devices pass controllers complex information sets about their internal state, etc.
The controller also has a number of sensors associated with it, such as device sensors 140, which may pass information from a specific device to the controller and may pass information from the controller to the device. For example, a controller could tell a device sensor to turn on, the sensor device could send the controller messages about the state of the sensor associated with the device, etc. Some device sensors pass controllers complex information sets about their internal state, etc. Space sensors 145 may also be associated with the controller. These, generally, give information about state of the physical space, or some portion of the physical space. They may also accept information from the controller, and pass information to the controller. In some embodiments, the controller can tell whether the space sensor is working as expected by reading the information the space sensor is sending. In some embodiments, the controller can look at the sensors around a specific sensor and see if the values being sent by a sensor are in line with other sensors. In some embodiments, the controller can tell if the space sensor can turn on and off correctly, send information signals correctly etc. Example of state that state sensors may read include temperature, humidity, noise levels, air flow noise levels, lighting levels, entertainment noise levels, CO2, VOC, and so on. Some of these devices and sensors may be connected by being physically wired to the controller 110, others may be connected by an interface network connection, e.g., 160. This network connection may be a wired connection, such as an ethernet connection, or may be a wireless connection. The controller may be able to determine if the space sensor is wired correctly to the controller.
Computer-readable storage media 170—any available non-transient tangible media that can be accessed within a computing environment—may also be included. Computer readable storage media 170 may comprise instructions 175 and data 180. Data Sources to provide data may be computing devices, such as a general hardware platform servers configured to receive and transmit information over communications connections 160.
At operation 205, a controller is provided. In some embodiments, this may represent multiple controllers. In some embodiments, at operation 210, multiple devices are provided. In some embodiments, the multiple devices are connected to the controller that is provided in operation 205 or to a different controller in the physical space 105. The controller(s) may control multiple devices. When controlling a device, the controller can, e.g., depending on the device and the controller, turn the devices on, turn the devices off, check that the signals coming from the device in various states is as expected, etc. Examples include the controller signaling a device to enter a certain state (e.g., on, off). The controller may then check to ensure that the device is behaving as expected. For example, the device wires should have certain signals (or lack any signal) when turned off. When the controller turns the device on, other signals may be expected on the wires. Devices may have intermediate states that can be set by the controller, as well.
At operation 215 a device sensor is provided. The controller may also be connected to one or more device sensors that provide information about a device. For example, a controller could tell a hot water heater to turn on high. After a given amount of time, the water in the water heater should have reached some temperature value. A device sensor associated with the hot water heater may be able to communicate the water temperature to the controller 110. The controller may know how hot the water should be if the device has been turned on for a specific amount of time at a specific setting. The device sensor can help the controller verify or falsify that the device is behaving as expected.
At operation 220 a space sensor is provided. The controller may also control at least one space sensor 145, within the physical space 105. A space sensor 145 may be used to measure the state of the physical space. Common space sensors include temperature sensors, humidity sensors, VOC sensors, noise sensors, water sensors, etc., as discussed above.
At operation 225 a model of the physical space 105 may be provided.
At operation 245 a model of device interconnections is provided. In some embodiments, the controller(s) check if a device is behaving as expected when the device is turned off. The controller memory may have information about expected device behavior in various states; this information may be in a model of device interconnections, or in another location. Among other benefits, this checks if the correct wires are wired to the correct controller connectors.
In some embodiments, the controllers turn a device on 235, using its connection with the controller. The controller may then check if the device is behaving as expected. For example, a device should be producing 10V of output along a specific wire when turned on. The controller(s) then can check that the appropriate voltage is on a given wire, as well as much other information associated with the device-controller connection.
In some embodiments, once a device is turned on, a device sensor associated with the device may also be turned on, or if previously turned on, then checked for its state. If a device is behaving as expected, the device state sensor should be at some value, or within some value range. If the device sensor is not within this range, it may indicate a problem with either the device or the device sensor.
In some embodiments, a space sensor is checked to see if it is behaving as expected 240. Space sensors may be checked against the values of other, e.g., nearby space sensors; space sensors may be checked against the behavior of devices that would affect state around the space sensor; if values are not as expected, then there may be problems with the space sensor, the space itself (which may have an undisclosed flaw), a device, which may not be changing state of the space sufficiently, etc.
In some embodiments, devices have specific requirements for validation. For example, an HVAC system may have air flow validation requirements, filter leak tests, particle counts, and the like. Device sensors or specific state change devices can be placed during construction that allow interaction between the device and the sensor to validate the device. For example, some devices for validation require humidity to be reduced within a certain time. A humidifier can be built initially into the building that then can be used to raise humidity to a high enough level that the humidity-reducing device (such as an air conditioner) can be validated.
Expected behavior comprises (if applicable) at least some of the signals that the device is expected to send to the controller to indicate functions of the device, current and voltage on the wire connection or connections, signals that the device is expected to send back to the controller when the controller sends signals, current and voltage on the wire(s) associated with the device when the device is turned off, current and voltage on the wire(s) associated with the device when the device is turned on, current and voltage on the wire(s) associated with the device when the device is in various states, the protocol the device is expected to follow for sending messages, etc.
With reference to
In some embodiments, the controller can check that it can communicate with the devices (such as sensors) that it is connected to. The controller can then report an error when it finds that a device is not communicating with the controller. The controller can send a signal to a device from the device's wiring pin (or pins) and then see what signal it receives back from the device (or device). If it receives the correct signal, then the controller can communicate with the device. In some instances, if the controller receives an incorrect signal or no signal at all, then the controller cannot communicate with the device(s). In such a case, the controller may report this communication error.
In some embodiments, the controller can also perform, for a connector wire, some combination of: a short circuit test, a cut wire test (also known as an open circuit test) or a proper connection test. The controller 110 comprises a computer program 125 stored in memory 120 and hardware 115 to be able to run the program 125 and perform such tests when a device or sensor is wired to one or more of its connectors.
The controller can determine the current and voltage that the wires are expressing, and can also determine the appropriate current and voltage for the wires associated with a device or sensor. If there is an error in any of these, the controller can indicate that an error has occurred. This indication may comprise writing to a file, displaying that an error has occurred on a display device, printing a report, making a noise, or any other error indication as known by those of skill in the art.
As the controller controls the devices and sensors, the controller can turn each device and sensor on. Once turned on, the controller can determine that the wiring connection is behaving as expected 515, 520 when turned on, which may entail giving the correct signal/voltage and current. If there is an error in any of these, the controller can indicate that an error has occurred. This indication may comprise writing to a file, displaying that an error has occurred on a display device, printing a report, making a noise, or any other error indication as known by those of skill in the art. In some embodiment, the errors the controller finds are reported on a display device.
With reference to
In some embodiments, the groupings of objects in the physical space that meet certain criteria are shown. Some possible groupings are subsystems 605, zones 610, equipment 615, and sensors 620. Subsystems may be large groupings, such as floors in a building. Zones may have smaller groupings within the subsystem such as portions of a floor of a building, e.g., living room, kitchen, laundry, etc. Equipment may be devices controllable by the subsystem that are not sensors. Other groupings are possible as well.
In some embodiments, the display changes as portions of the system record their commission results. When a sensor, equipment, zone, or subsystem is tested, its results are displayed as either pass 625, check 630, or fail 635. Pass 625 is indicated where expected behavior was produced. For example, the results could reach a threshold value, such as a numerical value, a percent of a maximum or minimum value, and so on. Pass results, such at the threshold value, may be set by a user, a commissioning standard, a default equipment pass threshold value, etc. Fail 635 is indicated when expected behavior is not produced. Check 630 is indicated when the behavior of the device is unclear and manual interpretation is required. As an example, when testing that an equipment subsystem (e.g., a boiler) can heat its connected zones, the controller may enable the boiler and then check that the temperature on the boiler output (which may be a sensor) increases properly. Corresponding zones to the boiler are expected to see an increase in temperature. If insufficient temperature increase in the sensors of these corresponding zones is recorded, then the results may comprise “check” or “fail”. If the controller does not detect enough of an increase in the corresponding zones the results are ambiguous and will require human intervention. In embodiments, devices that are near each other, connect to each other, or both may perform cross check validation. For example temperature sensors in adjoining areas should have temperature values that are within a range of each other. If one sensor value is off by a certain amount, that sensor may fail commissioning. If there are correct relationship behaviors between the sensors then the sensor may pass. If there is a correct relationship between a device and nearby sensors, then the sensor may pass. Many devices have correlated behavior, and as such may be cross-checked against each other.
Once the physical space has passed commissioning, in some embodiments, the building may be turned on to run in its normal fashion by selecting a “deploy” button 640.
Sensors can also be used to check that devices are properly commissioned. For example, a device, such as a heater 840 may be near a sensor 860 that reports on the state of the device. The plans for these sensors that help with commissioning may be put in at the design state, and then built such that the physical space can commission itself, as the sensor 860 will report if a device, e.g., heater 840 is operating correctly. These sensors may also help ensure that devices are running properly throughout the lifetime of the physical space. When a device is being commissioned, the controller may turn on the device for a certain time at a certain speed (if applicable) and then check the associated sensor. If the sensor changes state appropriately, then the device may have passed at least one test towards full commissioning. The device may affect multiple sensors, each of which may be checked by the controller. If the physical space uses multiple controllers, they may be connected using a distributed system, and so may be able to communicate such that sensors and devices wired to different controllers can automatically be used in the commissioning process.
Controllers also have access to databases of the physical space such that they can check that sensors in the space record the correct information for device activity, and sensors can cross-check each other for consistency.

A building is often commissioned prior to its first opening, and then commissioned every three to five years after that. Some innovative embodiments, such as those illustrated in
In some embodiments, commissioning engine 2065 runs the commissioning software using the processor 2015. In some embodiments, the running of the commissioning engine is divided over multiple processors running a distributed system.
The device is expected to be wired to the controller at a specific position. If the device has multiple wires, each wire has its own location, its own protocol, etc. In some embodiments, this device wiring position information is stored with relationship to the controller itself.
In some embodiments, method 2100 may be implemented in one or more processing devices (e.g., multiple processors running in a distributed system with multiple controllers, a digital processor, an analog processor, a digital circuit designed to process information, an analog circuit designed to process information, a state machine, and/or other mechanisms for electronically processing information). The one or more processing devices may include one or more devices executing some or all of the operations of method 2100 in response to instructions stored electronically on an electronic storage medium. The one or more processing devices may include one or more devices configured through hardware, firmware, and/or software to be specifically designed for execution of one or more of the operations of method 2100.
At operation 2105, a device in the physical space that is to be commissioned is selected, e.g., by the commissioning engine. The physical space model (or a different location in memory) may have, in memory 2010, a model of the devices to be commissioned.
At operation 2110 the, e.g., commissioning engine 2065 checks that the device is wired to the correct position on the controller.
At operation 2115, the device wires are checked to see if they follow the correct protocol. The correct protocol can be found, e.g., in a device wiring protocol 2030 database location stored with the device model 2025. There may also be a separate device wiring position 2070, or those may be included in the device wiring protocol. The information about the device may be already understood by the controller, and stored in a database, the information about the device protocol may be input by a user, such that the controller has access to it, or a combination of the two may be used.
At operation 2125, the sensors are checked to see if they are exhibiting expected behaviors, depending on device state. As discussed with relation to nearby sensor values 2060, to determine if a device is operating appropriately, a sensor may need to be checked. For example, to check if an air conditioner is working appropriately, a nearby sensor that checks temperature needs to be identified, or may already be identified. The temperature on the sensor then needs to be checked; the air conditioner needs to be turned on for a certain time by the controller using the air conditioner protocol stored in memory in the controller (or a controller within a distributed controller system); then the sensor needs to be checked again to see if the temperature has changed by the desired amount. If it has, the device passes the commissioning, if the temperature has not decreased by the required amount, then the device has either failed, or needs checking.
At operation 2130, device behavior is documented and stored such that it can be retrieved. This documentation is such that it can be retrieved when desired. This may be stored by methods known to those of skill in the art.
At operation 2135, it is determined if there are more devices to be checked. If so, then the method continues from operation 2105, until the devices that are to be commissioned are checked.
The specific devices that are to be wired to the controller are shown as device icons attached to their respective module connecters. At 2210, for example, we can see that the device is a Three Way Valve, with a 24 VAC (3-wire) protocol. It is attached to module 12225. It has three wires, which are of type (−), (O), and (C) from left to right, and which are in three distinct locations on the controller. When, for example, a device wire is wired to the lower left connection 2230 of the controller, the controller knows that it is to be a wire on a Three-Way Valve, with protocol 24 VAC (3-WIRE) and the specific wire is to be of type (−). Using this information, the controller can see what information is on the wire when connected, what signals the wire accepts, and what signals the wire is expected to return, etc. When the wire is connected to the controller, the controller understands what to do to test if the correct wire has been connected to that direct controller location. If wires have been swapped on a device (for example, the (−) and (O) wires are swapped such that the (O) wire is in the far lower left position 2230, the controller may be able to determine this, as it has the information about what signals can be expected to be sent and received on the wires. If the correct wire has been connected, then the controller may send a message to the module (through the module connecter and the circuit board) to tell an indicator 2235 on the module to signal that the correct wire is in place. In some embodiments, the indicator may indicate that the wire is correct with a light, such as a green LED light, a noise, etc. In some embodiments, the indicator may indicate that the wire is incorrect with a light, such as a red LED light, a noise, etc. In some embodiments, when a wire is connected in the module (the module in the controller, the controller having been told what wire to expect) the light will light up green if the correct wire is found to be connected (by the controller, module, or a combination) or will light up red if the correct wire is not found to be connected (by the controller, module, or some other combination).
