The invention discloses a near-zero energy consumption building energy supply method and system based on multi-objective optimization, and relates to the technical field of building energy efficiency and renewable energy application, and the method comprises the steps: collecting energy consumption data in a building, and constructing a multi-objective evaluation system according to the energy consumption data; performing weight optimization on the multi-target evaluation system to obtain an optimal weight coefficient; combining the optimal weight coefficient with a solar photovoltaic system and a ground source heat pump system, and establishing a renewable energy supply strategy model; and outputting an energy supply scheduling instruction of the building in each time period based on the renewable energy energy supply strategy model, and adjusting operation parameters of a solar photovoltaic system and a ground source heat pump system. According to the invention, by adjusting the operation mode of the equipment in real time, the balance between the energy efficiency and the comfort level is ensured, the common problem of energy efficiency waste or insufficient comfort level in the traditional method is avoided, and by means of intelligent scheduling and optimization, the energy consumption of the building can be effectively reduced, and the sustainability of energy utilization of the building is improved.

The invention discloses an air conditioner efficiency test system and a control method of an air conditioner efficiency test platform. The method comprises the following steps: dynamically adjusting the air dry bulb / wet bulb temperature of a test room of an existing test bed based on a dynamic temperature control adjusting technology; acquiring a real-time building thermal load of the test room through a building thermal load prediction simulator; the dynamic change of the air dry-bulb temperature of the test room is calculated in real time through the indoor air dry-bulb temperature prediction simulator; and the dynamic change of the air wet bulb temperature of the test room is calculated in real time through the indoor air wet bulb temperature prediction simulator. According to the invention, the problem that the dynamic operation energy efficiency and performance parameters of the tested air conditioner cannot be obtained through the enthalpy difference method test bench because the existing enthalpy difference method test bench cannot control the dynamic change process of the building thermal load of the test room along with the refrigeration / heating capability of the tested air conditioner in the prior art is solved; and the actual operation performance level of the air conditioner cannot be reflected.

The at least one server: receives the first information from the electrical meter, transmits the instruction to the electrical meter to change to the second mode of operation, and receives the second information.

Methods, systems, and devices for determination and notification of a location of a building safety system event are described herein. One embodiment includes a method for notifying a user of a fire system event, comprising detecting an event in a building through an event detection device and transmitting information about at least one of the event or the event detection device to a remote server and to a first computing device. The first computing device may include a memory wherein floorplans of each floor of the building are stored. The method may further comprise determining, based on the information and through the first computing device, a floor of the building on which the first event was detected; transmitting a particular floorplan of that floor to the remote server; determining a specific location within the floor at which the first event was detected; generating a visual floor representation, including an indication of the specific location, based on the particular floorplan and the specific location; and transmitting the visual floor representation to a software application comprised of executable instructions stored in the memory of a second computing device to present the visual floor representation to a user.

The embodiments provide a system and method for filtering out smoke and / or toxic gases / fumes from air in a building. The system integrates various smart devices with an HVAC system along with a controlling software application that can change the state of the smart devices, thereby controlling the types and quantities of air moving through the HVAC system at any time. In particular, the system can adjust the openings of one or more smart registers to control how much air passes in and out of the HVAC system over a given period of time. The system can also adjust the opening of a smart intake vent to control how much fresh (outside) air passes into the system over a given period of time. The system can also adjust the opening of a smart furnace valve that is disposed within the furnace.
