In June 2009, the "Law Concerning the Promotion of Popularization of Long-Term Quality Housing" was enacted. On the other hand, along with the promotion of domestic timber, there is a considerable stock of wooden houses not only for housing but also for public buildings. According to data, about 40% of all buildings in Japan are made of wood, and about 90% of houses (detached houses) are made of wood. Under these circumstances, Japan is in an environment with high humidity and natural disasters such as earthquakes and torrential rains. Detecting the state of deterioration of things is becoming more and more necessary in the spread of the above-mentioned long-term quality housing.

However, the effectiveness of inspection measures is highly dependent on the problem awareness level of each construction company. Currently, there are cases where periodic human checks are performed, and there are cases where periodic inspections are not performed. In addition, it may be so-called coping therapy after the problem is discovered. This is the situation. In other words, at present, periodic inspections are required to ensure the performance of long-term quality housing (earthquake resistance, wind resistance, energy conservation, ease of maintenance and management, etc.). However, there is a problem that it depends on the burden and the level of awareness of the problem. Therefore, there is a need for a mechanism that predicts the occurrence of a deteriorated state in advance without being influenced by the aggressiveness of the entity that carries out inspection measures.

From such a point of view, as a system that does not rely on manual labor, there is a housing management method as described in Patent Document 1, for example. For example, this technology inputs a predetermined detection signal to an optical fiber embedded in a building material so as to be integrated with the building material, and monitors changes in the signal transmission characteristics of the optical fiber over time. Techniques have been disclosed to monitor for applied strain, water leaks, condensation, fire, and the like.

In addition, Patent Document 2 discloses a ventilation system for a building having a ventilation layer in the outer wall wall body. A temperature sensor is installed to measure the temperature of each part of the ventilation layer inside the body, such as under the floor, the outside air, and the outer wall wall, in order to select the optimum air introduction point from the ventilation layer air supply port that takes the air in the ventilation layer into the room. , a technique for performing control based on temperature information of each part thereof is also disclosed.

3 and 4 will be used to explain in more detail than the explanation using the schematic block diagram of FIG. An inner wall 35 between the room 5 and the wall 7 has a hole through which a sensing unit body cover 39 for housing the sensing unit body 41 is attached. A wireless transmission section 41a is provided at the tip of one end side of the sensing unit body 41, and an indoor sensing section 41b is also provided at one end side. . An outdoor sensing portion is provided on the other side of the sensing unit body 41. Here, two of an indoor side wall inside sensing portion 41c and an outdoor side wall inside sensing portion 41d are provided. there is Holes 39b and 39c for improving sensing sensitivity are formed in the sensing unit body cover 39 corresponding to the indoor side wall internal sensing portion 41c and the outdoor side wall internal sensing portion 41d.

Also, regardless of the presence or absence of the indoor sensing unit, when it is installed on the floor 11, it is preferable to use a bowl-shaped rounded protruding portion to avoid affecting the indoor space as much as possible. Even if there is a portion that protrudes into the room, embedding it in the wall or the like can reduce the impact on the indoor space.

Hereafter, the above system and vital data are sensed for various purposes by IoT, and by linking them with big data and processing information, in addition to maintaining the performance of the house, it is possible to extend healthy life expectancy, save energy, and optimize life from the viewpoint of security. Describe what can be done.

First, the following countermeasures can be taken to address the issue of how well the seismic performance calculated at the time of design is maintained after construction.

[Earthquake resistance retention]
By sensing environmental data as described above, it is possible to reduce the risk of damage caused by rot fungi and termites, prepare for a major Nankai Trough earthquake, visualize the timing of countermeasures, and make efforts to minimize damage.

Next, the following measures can be taken to effectively control the housing environment, reduce the risk of illness for residents, and extend healthy life expectancy.

[Extension of human healthy life expectancy]
Based on the research results of the SWH (Smart Wellness House), add sensors that can detect the heat and air environments between rooms, visualize the correlation with vital data, and issue an alert if a dangerous situation occurs. It will also be possible to instruct residents on specific actions to reduce the risk of contracting the disease. Here, SWH is a house aimed at energy-saving and healthy living. Promoting National Conference” was adopted, and verification and enlightenment projects have been started since 2015, and have continued to this day. In addition, by automatically controlling the optimal thermal and air environment, it is possible to provide a thermal and air environment that reduces the risk of illness, and the more appropriate indoor environment increases the amount of activity of the residents and improves their health. Life can be extended. From the SWH verification data, heat shock, a cardiovascular disease caused by the coldness of winter, and house sickness, a respiratory disease caused by pollution of the indoor air environment (VOCs, mold spores, house dust from dead mites, etc.) have been found to significantly reduce risk when addressed in the home. Here, VOC (Volatile Organic Compounds) is a general term for organic compounds (toluene, xylene, ethyl acetate, etc.) that are volatile and gaseous in the atmosphere, and are released into the environment. In recent years, sick house syndrome and chemical hypersensitivity caused by formaldehyde have been widely recognized in society and become a problem.

[Collaboration with medical institutions]
By linking the system with family medical institutions, it is possible to reduce medical expenses for individuals and the country, at-home end-of-life care, community-based integrated care, home-based medical care, solitary death, and pre-symptomatic measures for elderly people living alone.

Next, the countermeasures and their effects will be explained from the viewpoint of energy saving and cost saving.

[Insulation performance maintenance]
From the perspective of how well the insulation performance calculated at the time of design is maintained after construction, the correlation between outdoor and indoor temperatures can be monitored to reduce utility costs and positively affect healthy life expectancy. It is possible to improve the energy self-sufficiency rate.

[Automatic control with passive systems such as sunlight, wind, and humidity]
It is possible to work on heating and cooling (indoor mechanism adjustment) by using natural energy such as the sun, natural wind, temperature changes, and earth heat through ingenuity in architectural design without using special power equipment. Although it is a passive system, it is possible to use dilute energy and renewable energy by controlling the temperature and humidity with an automatic window opening and closing system and controlling the solar radiation with an automatic shade system to control the residential environment in an energy-saving manner. effect is obtained.

[Automatic control of air conditioners, humidifiers and dehumidifiers]
Active systems are design methods that aim to secure a comfortable living space by efficiently combining artificial objects such as air conditioners. Active systems can be controlled with energy savings next to the above passive systems. .

[Linked with HEMS]
HEMS (Home Energy Management System) is a system that connects air conditioners, lighting, home appliances, etc. by wire or wireless, and visualizes the power being used on a monitor, etc., but it can also be connected to solar power generation and storage batteries. Therefore, by linking with such a system, it is possible to increase the energy saving effect by visualizing power consumption. In addition to HEMS, a smart meter is a meter connected to the Internet to automatically read household power consumption, and this can also be linked. In other words, by combining HEMS and smart meters as a set, CEMS (Community Energy Management System) and AEMS (Area Energy Management System) can be realized, and the energy saving effect can be increased by making electricity more visible.

The following is an explanation from the viewpoint of Home Security.

[Fire measures]
As a countermeasure against fire, it is possible to respond quickly in the event of a fire by linking it with a heat sensor/smoke sensor and making it a system that notifies the fire department and the police.

[Security]
By incorporating it into a crime prevention system, it becomes possible to detect illegal intrusions, notify the police or a security company, and respond quickly to illegal intrusions.

Other applications are described below.

From the point of view of whether it is possible to objectively make investment decisions to maintain or improve housing performance, the following developments can be envisioned.

[Lifetime housing costs (degradation, fuel consumption, medical expenses)]
Based on the above data, we can calculate and provide the lifetime cost of living in that house. As a result, residents can visualize the cost of their current housing, including health costs.

[Formulation of a home renovation plan]
Compare lifetime housing costs with performance upgrade plans to support future investment decisions. As a result, it is possible to make an investment decision as to whether it is more profitable to improve housing performance in a total sense.

The above data are accumulated in the housing performance history evaluation system so that the objective asset value of the housing can be evaluated in a timely manner. Here, housing history information stores and accumulates records such as how a house is constructed, what kind of performance it has, and what kind of inspections, repairs, and renovations have been carried out after construction. , Regarding this housing performance history evaluation system, the Ministry of Land, Infrastructure, Transport and Tourism, taking the opportunity of the spread and promotion of long-term excellent housing, emphasizes maintenance and conservation as a pair that is indispensable for living over generations. We have been disseminating information since 1998. With this housing performance history evaluation system, the seller is evaluated that the house is properly built and maintained, and the buyer can know the concrete value of the building. As a result, it will lead to activation of the second-hand market.

[Reduction of after-sales maintenance]
By building an automated system for after-sales maintenance services, it is possible to reduce the number of maintenance services required by housing makers, which increases as more buildings are built, through sensing. From time to time, necessary maintenance can be carried out.

[Application to spaces other than houses]
It can be applied to non-residential spaces such as trains, ships, airplanes and cars.

[Application to pets]
It can be used not only for humans, but also for extending the healthy life expectancy of pets in the home.
