Systems and methods dynamically assess energy efficiency by obtaining a minimum energy consumption of a system, receiving in a substantially continuous way a measurement of actual energy consumption of the system, and comparing the minimum energy consumption to the measurement of actual energy consumption to calculate a substantially continuous energy performance assessment. The system further provides at least one of a theoretical minimum energy consumption based at least in part on theoretical performance limits of system components, an achievable minimum energy consumption based at least in part on specifications for high energy efficient equivalents of the system components, and the designed minimum energy consumption based at least in part on specifications for the system components.

A method of controlling tint of a tintable window to account for occupant comfort in a room of a building. The tintable window is between the interior and exterior of the building. The method predicts a tint level for the tintable window at a future time based on a penetration depth of direct sunlight through the tintable window into the room at the future time and space type in the room. The method also provides instructions over a network to transition tint of the tintable window to the tint level.

A site monitoring system may analyze information from sites to determine when a device, a sensor, a controller or other structure associated with optically switchable devices has a problem. The system may, if appropriate, act on the problem. In certain embodiments, the system learns customer/user preferences and adapts its control logic to meet the customer's goals.

A system to facilitate processing of recyclable items is disclosed. Further, the system may include a communication device configured for receiving event data associated with a recycling process from at least one sensory device, receiving a request for the event data from a first user device, and transmitting the event data to the first user device based on deducting of a predetermined amount of crypto tokens from a first crypto account associated with the first user device. Further, the system may include a processing device communicatively coupled to the communication device, configured for deducting the predetermined amount of crypto tokens from the first crypto account. Further, the system may include a storage device communicatively coupled to the processing device, configured for storing, using a distributed ledger technology, the event data, and data related to the deducting of the predetermined amount of crypto tokens from the first crypto account.

The present invention provides Augmented Virtual Models accessible via Orienteering using a smart device. The smart device is operative to identify a position within a building and use fine-grain location monitoring to guide a user to a desired location. Upon reaching the desired location, the user can point the smart device at a wall or component and learn, query, or supplement technical details and other information about the wall or component. Technical details and other information are stored in an augmented virtual model of the building.

A system for locating an object in a volume of space can include a communication device of the object disposed in the volume of space, where the communication device broadcasts a first communication signal into the volume of space, where the first communication signal includes a first identification of the object. The system can also include multiple integrated sensor devices disposed in the volume of space, where each integrated sensor device includes at least one sensor, at least one receiver, and at least one transmitter, where the at least one receiver of a subset of the integrated sensor devices receives the first communication signal, where each of the subset determines a signal strength of the first communication signal. The system can further include at least one access controller that receives at least one second communication signal sent by the subset.

Method and apparatus for conducting a Service Call in a structure using orienteering methods. The AVM may assist in determining whether or when equipment needs repair and can automatically call a service technician. By referencing the AVM on a smart device, the technician can quickly and easily locate the equipment to be repaired. Additionally, the data contained within the AVM may provide valuable clues to solving any service-related problem. Technical walkthroughs may also be displayed on the service technician's smart device.

A device may include a plurality of controllable components, an input to receive a waste stream including carbon dioxide and volatile organic compounds, and a foam trap coupled to the input. The device may further include one or more sensors coupled to the input and configured to generate an electrical signal proportional to a concentration of at least one compound within the waste stream. The device may also include a control circuit coupled to the one or more sensors and configured to selectively activate one or more of the plurality of controllable components in response to the electrical signal.

Method and apparatus for responding to an emergency using orienteering methods. An Augmented Virtual Model (AVM) may assist in determining the nature of the emergency and a path to be taken by an emergency responder. By referencing the AVM on a smart device, such as one located in the visor of a firefighter, the emergency responder can quickly and easily locate a cause of the emergency and address it, as well as rescue lives endangered by the emergency.

An extension cord includes a plurality of electrical conductors. A plug is configured to electrically couple a first respective end of the plurality of electrical conductors with an electrical receptacle of a power source. An outlet assembly is coupled with a second respective end of the plurality of electrical conductors. The outlet assembly may include one or more outlet receptacles configured to provide electrical power from the power source. A power meter may be configured to measure an electrical draw through the outlet assembly and to provide a user perceptible output based upon the measured electrical draw. A carbon monoxide monitor may be configured to detect an environmental carbon monoxide level proximate the outlet assembly and to provide a user perceptible indication when the detected environment carbon monoxide level exceeds a threshold.
