IoT in Building Maintenance Services – Joint Field Experiment Started
Project 1: Remote Monitoring of Building Signs and Preventive Maintenancewith Sensing Technology
XYMAX Corporation ("XYMAX") and Optex Co., Ltd. ("Optex") collaborate in projects to develop newbuilding maintenance services with Internet of Things ("IoT") technologies. As their first project, they
started a field experiment, in which they use sensing technology to monitor the condition of building signs,and consider what kind of maintenance services are possible with this technology.
Maintenance services have a long checklist to inspect the condition of building, its facilities, workplaceenvironment and other areas; those services are provided to keep the building safe, and such checklist iscompulsory under the law. There is, however, no specific way to check the condition of signs on theexterior wall of buildings (except for the visual check). Old signs fell in many places across Japan and many
local governments are trying to change their rules on outdoor advertising signs because accidents like thisare expected to happen more often. One of the problems is that it is hard to inspect the condition ofbuilding signs because they are on the upper part of a building. The daily visual check alone is not enoughto notice deteriorated areas and bad conditions since signs are used in a harsh environment (winds, rains,sunshine, etc.).
XYMAX and Optex are focusing on the monitoring of building signs and prevention of accidents: theseareas have been neglected but are actually very important for the safety of buildings. Aiming to start
services of remote monitoring and preventive maintenance of building signs, the two companies examine
the effectiveness of the technology and potential services and identify possible problems.
XYMAX is a management and operation service provider for many properties and has the know-how insafety inspection, repair and maintenance. Optex has the sensing technology which can recognize human,vehicle, thing or condition; it works accurately even in a harsh environment. The two companies aim toprovide new IoT services by combining their experiences.

Field Experiment
We installed a sensor terminal on the building signs to measure the angle of inclination and swing, and weare accumulating such data. We have started the field test with 20 sensor terminals (11 in Tokyo, 6 in Aichi
and 3 in Osaka). The installation and the durability of the sensor terminals are examined and data aregathered. The purposes of this field test are to check how useful the data is, perform technical test andestablish the method of providing services.

Potential Services
We will accumulate the data of inclination and swing in cloud environment. The accumulated data
indicates the changes over time. We will use this data and develop a life-time support service of building
signs including daily remote monitoring, preventive maintenance planning, inspection and repairs.
System of Potential Services

Accumulate the dataon the cloud.

Install a sensor.
Receive data ofinclination and swing.

Monitor the data.

Inspection & Repair/Replacement
Comments from Clients who agreed to install the Sensor for Our ExperimentHome appliance store
We check the building signs visually and by touch, but there is no guideline and it is difficult to judge withconfidence whether the signs are alright. And, such check can only tell the condition at that point in time; itcannot predict what happens next. We are hoping that measuring and monitoring of the building signs
with the sensor will be useful in making right decision to perform preventive maintenance and repairs.

We inspected the building signs on a periodic basis. Although we are willing to continue the appropriate
maintenance, it is not easy because inspections need the aerial work platform truck as well as thepermission to occupy the road. That is why only visual inspection is possible in a daily check. Even if weremove the exterior of the building signs and touch inside, such inspection is based on personal
experience of the maintenance worker, which cannot be expressed in number, and there is no specificguideline. We are hoping that this experiment will be able to show the inclination and swing in actual
number so that we can judge the condition more appropriately.

2With the outcome of this field experiment and by solving problems, we will make further progress toachieve the practical use of the remote monitoring services and preventive maintenance services ofbuilding signs. We believe it is important to provide not only the analysis of the data but also value-added
services because using the IoT (sensing technology, etc.) and advanced technology (IT infrastructure suchas communications, cloud and AI) in the field of building maintenance can give a great impact on theworkflow of the services. XYMAX and Optex will work together to design effective services with the use ofIoT and contribute to the safety of buildings. We will build a reliable technology and system for providing
the services as soon as possible.
