Modularization of emergency evacuation shelters in the event of a disaster. Self-sufficiency in energy and water is possible. The first construction company to start modularization will become the standard and gain huge vested interests.

The proposed structure is a pyramid-shaped structure with solar panels installed on all the above-ground walls, and the angle at which solar energy can be used most efficiently, taking into account the movement of the sun, was investigated. Based on this, the construction of a pyramid-shaped structure was proposed.
In the gaps between the solar panels, a groove about 3 to 5 cm high and deep was created, which would allow rainwater to flow efficiently from top to bottom diagonally and into the center.
The groove would be used as a foothold for cleaning and other maintenance, and it would also serve as a stopper for slipping and to increase the chance of tripping on fingers or feet. In the worst case scenario, artificial or natural plants would be placed around the bottom of the ground to act as a buffer material, so that even if someone were to slip down, they would be safe.
This would reduce the chance of injury during maintenance and cleaning.
The lowest level underground would be a water storage tank, and an underground water purification facility would be built using various methods such as a filtration purification system and microbial decomposition to store purified, clean drinking water.
It is estimated that this would allow the domestic wastewater used inside the pyramid to be reused.
In addition, a plan for a circulating water channel with pipes on the exterior walls of both the above-ground and underground buildings was also proposed. This will allow for the possibility of storing more water, not just in underground water tanks. Furthermore, in summer or when the outside temperature is high, it will be possible to use it as hot water, and a system to store that hot water will be constructed, allowing for efficient use of hot water for group bathing, showers, and daily life.
Hot water will be stored in a hot water storage system, and it is expected that the temperature inside the building will be lowered by flowing it to the upper part through a circulating water channel on the underground exterior wall.
Since the uppermost part is small in area, a system will be constructed to monitor the inside.
The residential area will be mainly on the ground level, and in some cases, it may be better to make some of the solar panels glass so that the outside can be seen, which may help prevent people from accumulating stress. If
this glass area is necessary, we will consider creating several such lounge-like spaces on each floor.
Basically, the residential area will be built as individual rooms so that individuals or families can live there.
The interior lighting will use low-power LEDs.
In densely populated areas, commercial facilities will be built inside, and if supermarkets, convenience stores, hospitals, pharmacies, Uniqlo and other facilities where you can buy clothes at low prices and places that mainly handle recycled clothing can be built, there will be no need to worry about clothing in the event of an emergency evacuation. From this perspective, laundry facilities may also be necessary. Considering things like public baths that can be used by groups, there is a great possibility that people will naturally recognize that they can be used as evacuation shelters in the event of an emergency, while also using them during normal times when there are no disasters. Depending on the scale, it may be possible to create a pool or exercise space in the underground facility.
In the case of a pool, the water can be purified and used as an emergency water source, so it can be thought of as a facility for further storage of water sources as well as stress relief
. Furthermore, the area of ​​a pyramid decreases the higher it goes up, and unlike buildings and other structures that are built directly above, there is very little risk of it collapsing or being destroyed. If earthquake-resistant materials are used, safety can be further ensured.
It is believed that this structure is the reason why Egyptian pyramids have continued to exist for thousands of years. Even in areas with few earthquakes, it is assumed that disasters have occurred over hundreds of years, and the fact that they have still survived to the present day suggests that this structure was extremely excellent.
Next, from the perspective of how to achieve a certain degree of self-sufficiency in terms of food issues, food plants will be created on the lower levels below ground. This is based on the idea that cultivation in large areas on the lower levels is the most efficient from the perspective of utilizing the large areas.
There are two types of cultivation: hydroponic and soil cultivation. For soil cultivation, we will mainly focus on plants such as potatoes and soybeans, which can grow and be cultivated continuously even in poor soil quality. We
believe that potatoes provide carbohydrates as an energy source, while soybeans provide a source of protein.
Hydroponic cultivation could become a more efficient cultivation method if data can be obtained by monitoring which plants grow best in which water.
In some cases, it may be possible to cultivate freshwater organisms in hydroponic tanks.
These are just a few ideas that we came up with, but are there any ideas that are impossible to realize or that are missing?

What a detailed and interesting idea! The proposed pyramidal building has many advantages, especially in terms of sustainability and safety in the event of a disaster. Below, we give our assessment of each element of the proposal and provide suggestions for improvement.

### Conclusion

Overall, it's a very practical and sustainable design idea. Its feasibility will require detailed technical assessment and adjustments based on local needs, but the basic idea is very good. Considering the specific technology and material selection, as well as a long-term operation plan, will bring the idea closer to reality.

From the perspective of emergency evacuation shelters in case of disasters, it would be best to nationalize this facility or have it promoted by local organizations. Profits from the commercial district can be used to purchase and transport supplies that are in short supply. They can also be used to fund the construction of new pyramid-shaped evacuation shelters. If this spreads across the country and there is no longer a need to build new ones, I think a new source of revenue could be created by taxing the profits.

That's a very good point! There are many advantages to nationalizing and having local organizations promote evacuation shelters during disasters, such as:

### Advantages and feasibility

1. **Stable Funding**
- **Evaluation**: The revenue from the commercial district will provide a steady flow of funds needed to purchase supplies and build new facilities.
- **Feasibility**: By increasing commercial activity in the area, you can expect to make a profit, making it sustainable.

2. **Tax revenue**
- **Evaluation**: By using the revenue as a tax, new financial resources are generated and can be used for regional infrastructure development and disaster prevention measures.
- **Feasibility**: By focusing tax revenue on regional disaster prevention measures, residents' sense of security can be increased.

3. **Building a Nationwide Network**
- **Evaluation**: By expanding pyramid-type evacuation shelters to various regions, a nationwide disaster prevention network will be formed and cooperation between regions will be promoted.
- **Feasibility**: By collaborating with local governments and residents to create facilities that take advantage of the characteristics of each region, disaster prevention measures that are more locally rooted can be realized.

4. **Stimulating the local economy**
- **Evaluation**: The construction and operation of new evacuation shelters will create jobs and revitalize the local economy.
- **Feasibility**: By employing local residents, the local economic base will be strengthened and support systems in the event of a disaster can be improved.

5. **Education and awareness raising**
- **Evaluation**: It is possible to provide disaster prevention education to local residents through the operation of evacuation shelters.

In this way, nationalization and promotion by local organizations are not only economically beneficial, but are also very effective means of enhancing local disaster prevention capabilities and protecting the safety of residents. Proper planning and local cooperation are essential to success, but by building a sustainable system, it will be possible to create a society that is resilient to disasters.

If this modularized production idea were to be used in the first emergency evacuation shelters in Japan, it would be possible to create emergency shelters in a short time, and in some cases, if they could be transported, they could be quickly set up even after a disaster
. Rather than sleeping together in a local gymnasium or other facility, I speculate that if they were individual rooms with soundproof walls, the stress of evacuees could be significantly reduced.

Applying modular manufacturing ideas to emergency evacuation shelters in times of disaster is a highly effective approach. Below are some of its specific benefits and implementation methods.

### Conclusion

The idea of ​​a modular emergency evacuation shelter is extremely effective in responding quickly to disasters. Providing private rooms reduces stress for evacuees and creates a more comfortable evacuation environment. This approach also contributes to post-disaster reconstruction support, thereby increasing the safety of the entire local community.

In Japan, if this modularized facility could be installed when the permanent emergency evacuation shelters, including commercial facilities, and the population capacity exceeds the capacity, it would be advantageous for residents to overcome the disaster safely and comfortably, and to quickly recover, except for cases where people are injured in accidents caused by the disaster. If there are modules
large enough for individuals or families to live in, the modules can be assembled and completed by simply digging holes for installation once the rubble is cleared, and the pyramid-shaped exterior walls are solar panels, making it possible to be self-sufficient in energy.
All that's left is to modularize the internal units to include a unit that collects and purifies rainwater, a unit that turns domestic wastewater into a renewable clean water source, a tank unit that stores purified clean water, a unit that stores solar energy, a system bath and system kitchen unit, and a unit for living space, and it would be perfect.

Your proposal is very comprehensive and includes practical ideas to significantly improve living conditions in the event of a disaster. Below, we will summarize its advantages and specific elements, as well as provide further points to consider.

### Advantages of the proposal

This approach will enable them to live a rich life while minimizing the burden on the environment.

The original idea for the building itself was to have the above-ground exterior of the upper and lower pyramids all covered in solar panels, and some of the floors would be made of glass to serve as a lounge-like facility with a view of the outside, a system to efficiently collect rainwater by creating diagonal grooves for the solar panels, and a water purification system using a huge water storage tank, filter filtration, and microbial decomposition in the basement, along with a purification system to reuse domestic wastewater from the residential area.
A circulating water channel system will be built just behind the exterior walls to increase the amount of clean water stored in the building itself.
The above-ground area will be used as a residential area for humans, with soundproofed rooms for individuals and families to live in.
In terms of area, the lower floors will be used for food production, with two types of cultivation proposed: soil cultivation and hydroponic cultivation. In soil, potatoes and soybeans, which can be grown continuously even in nutrient-poor soil, will be the main crop, and in hydroponic cultivation, freshwater creatures will be cultivated in aquariums at the same time to increase self-sufficiency.
Commercial facilities will be attracted to the basement.
Connecting to nearby cities above ground or through underground passages,
these ideas will create an environment where people can live in places where it was previously uninhabitable, and since there is no need to clear the surrounding forests, only a minimum amount of land will be secured, this will reduce the destruction of nature and vacant lots.
Energy will be provided by clean energy from the solar panels on the exterior walls of the pyramid, so it will not lead to environmental degradation.
In addition, because of the pyramid shape, there are few areas that are shaded, so it is thought that there will be little impact on the ecosystem.
