Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and a system for measuring equipment usage in a building.

[0002]

2. Description of the Related Art As part of measures to prevent global warming, the construction industry has shifted from scrap and build to social stock and renewal of existing buildings. In particular, since the collapse of the bubble economy, the stock of office buildings, especially in the city center, has been expanding, and the demand for renewal work for accompanying facilities has been rapidly increasing. Renewal work is expected to account for more than 50% of total completed work in the first half of the 21st century. Against this background, accurate judgment of the renewal of equipment, determination of the optimal time, efficiency, and reduction of costs are essential issues. The importance of obtaining data on the situation is indicated. However, there was no method for measuring such data or a system for managing such data, and at the most, a meter was provided for toll collection.

[0003]

If the meter is installed, the reading and recording of the meter and the storage and management of the recorded data must all be performed manually. Even if it takes time and effort to collect data, it is not necessary and sufficient data to estimate the energy saving effect and the water supply load in advance and make design studies only with quantitative data. Not only the total usage, but also how each appliance is used,
It is essential to use data on the usage status, such as the occupied time, the number of times, and the number of times the device is operated. As described above, there is no method or system for measuring the data on the usage status, and it has been impossible to indicate the optimal time of renewal with a clear value. For example, when trying to renew the equipment, it was completely unclear whether the equipment was really deteriorated or whether it was appropriate to renew at this time. Starting the actual survey of equipment at the examination stage, etc., and diagnosing and confirming the necessity of renewal based on the management records would take time and avoid the possibility of missing the optimal renewal time. I can't. Because of the time required, even residents who use the facilities are inconvenienced. As described above, the renewal could not be efficiently performed and the cost could not be reduced. In addition to the renewal, there is no accumulation of data on the water supply load, so the entire equipment was designed to be excessively wasteful. Therefore, in the present invention, in order to obtain data useful for achieving appropriateness of the renewal of the water supply and drainage facilities and optimizing the timing of the renewal, optimizing the determination, increasing the efficiency, and reducing the cost, the time and space of the water supply load are also obtained. The purpose of the present invention is to provide a method for measuring the usage of instruments and a system for managing them, which can be used for a water environment plan that can save and effectively use all energy by grasping the characteristics of dynamic variation. I do.
