It is a figure showing an example of the check sheet displayed on the check sheet display window.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

Embodiment 1
FIG. 1 shows a schematic configuration of a building management device 1 according to the first embodiment. As shown in FIG. 1, the building management apparatus 1 is connected to various facilities 2 provided in a building such as a building. The equipment 2 is, for example, an air conditioning equipment, a heat source equipment, a lighting equipment, a security equipment, and a disaster prevention equipment.

  Each facility 2 has equipment of different types. Each equipment is specified as a management point in the building. Data on the energy consumption of each facility device is transmitted from each facility 2 to the building management device 1 via the communication line 3 and used for energy saving operation of each facility device.

  The equipment includes, for example, a fan of an air conditioner that takes in air from the room, a coil of an air conditioner that controls the temperature and humidity of the air taken in from the room, a heat source of water (eg, cold water, hot water) sent to the air conditioner, air conditioning These include a water supply valve that adjusts the amount of water supplied to the machine, and a transfer pump that sends out water from the heat source toward the air conditioner.

  As shown in FIG. 1, the building management device 1 includes a data collection unit 11, a data storage unit 12, a check sheet creation unit 13, a display unit 14, and an operation input unit 15.

  The data collection unit 11 collects data on the energy consumption of the respective equipment from the respective equipment. The data storage unit 12 stores the data collected by the data collection unit 11 corresponding to each equipment.

  The check sheet creation unit 13 creates a check sheet for evaluating the collected and stored data. The check sheet relates to the energy saving operation of the facility equipment, and is created in advance for each facility 2 based on the past experience, knowledge, and results. For this reason, the operator can be naturally guided to the PDCA cycle by performing evaluation work on each data along the check sheet, and can obtain the energy saving effect of the building.

Here, the PDCA cycle is one of management cycles for performing quality control, business improvement, and the like in business activities. The PDCA cycle consists of the following four steps.
・ Plan (plan): Create an evaluation work plan based on experience, knowledge and results.
・ Do (Implementation): Implement the work according to the plan.
-Chech (evaluation): Check if the implementation of the work is in line with the plan.
Action (Improvement): Examine and treat the part where the implementation is not in line with the plan.

  Therefore, the work of creating a check sheet corresponds to the planning step of the PDCA cycle. Next, along with the check sheet, the operation of evaluating the data collected from the equipment corresponds to the implementation step. The operation of determining whether the evaluation result obtained along the check sheet is appropriate corresponds to the evaluation step. Finally, the task of implementing the remedies obtained along the check sheet corresponds to the remedial steps.

  The display unit 14 is a screen display device such as a display, and has a display screen 14 a. The display screen 14a displays, for example, the number and name of the equipment and data corresponding to the equipment.
