This is a traditional wooden house construction method with a "structural monitoring and management type" that has been coated with a special conductive paint made from natural materials and bamboo charcoal.
The Black Frame Construction Method is an environmentally friendly technique that utilizes a special bamboo charcoal conductive paint called 'e-Pass.' By applying this paint, wooden structures can maintain a healthy condition over the long term and ensure comfortable living performance. Additionally, it enables the quantification and evaluation of the condition of the structure according to domestic patent No. 5793784. This method allows for continuous monitoring without causing damage to finishes (non-destructive), facilitating easy inspections and accurate repairs (maintenance). It corresponds to the 'visualization' of structural evaluations in stock housing and is a CO2-sequestering (CO2 stock) environmentally conscious construction method.

basic information
Ultra-high durability health structure fused with special bamboo charcoal and cutting-edge technology 1. Antibacterial effect Wood decomposes and rots due to various wood-decaying fungi in nature, but the antibacterial effect prevents the corrosion of the structure. 2. Humidity control effect By maintaining a constant humidity level, it protects the wood throughout the four seasons. Additionally, even when submerged in water due to leaks or rain, the wood does not absorb moisture. 3. Deodorizing effect It eliminates various household odors, creating a comfortable living environment. 4. Chemical substance decomposition effect It has the effect of adsorbing and decomposing environmental hormones (such as formaldehyde). 5. Mold prevention effect It functions to prevent various types of mold and bacteria. 6. Dust mite prevention effect It prevents the invasion and reproduction of dust mites, with an efficacy rate of 100%. 7. Safety and durability The adhesion of the coating material is very strong and difficult to peel off, and the surface is extremely hard, showing little degradation. 8. Termite prevention effect (synergistic effects of each function) The first function prevents the proliferation of wood-decaying fungi and exterminates them, while the third and fourth functions adsorb and deodorize pheromones, making it difficult for termites to locate food sources. The coated surface is so hard that even rubbing it with a coin wears down the coin, thus providing strong protection for the wood surface.

Applications/Examples of results
Initial Costs (At Contract Signing) 1. Security Deposit (3.5 million yen) In the first year, due to challenges such as construction familiarization and sales development, we will provide startup support for five buildings over two years. This startup support includes technical training and sales assistance, and we will hold a security deposit of approximately 3.5 million yen, which is considered necessary for about five buildings. The security deposit will be fully refunded once the target of five buildings is achieved within two years. We will respond to any necessary adjustments with current business partners (pre-cut factories, etc.) as needed. Regarding technical training and sales support, there may be cases where actual expenses such as transportation costs need to be reimbursed depending on the content. 2. Sales Support Tools such as Brochures Printing of the company name (logo, etc.) and contact information on the inquiry section of our existing brochures (actual cost). Display on the retailer introduction section of our website. 3. Introduction of Other Products and Our Partner Companies We can provide thermal insulation paint "Thermal Guard Series" and sell LED-related equipment (lighting fixtures, digital signage, etc.), as well as introduce the "HS Joint Purchasing" offered by Housing Solutions Co., Ltd. as a measure to reduce the financial burden on clients. (There may be a need for screening when companies join.)
Detailed information

The special bamboo charcoal conductive paint "e-Pass," designed specifically for the black frame construction method, is primarily made from high-purity bamboo charcoal produced in a dedicated special carbonization furnace. "Bamboo charcoal" is a material that purifies the air in a room, adsorbs unpleasant odors, adjusts humidity, and offers various benefits for daily life. One of the secrets to its effectiveness lies in its porous nature. Bamboo charcoal has a structure with countless fine pores throughout its interior (i.e., it is porous). As a result, it has a large surface area and exhibits excellent adsorption power. It also has the potential for humidity regulation and relaxation effects due to infrared radiation. Bamboo charcoal is a health material that protects modern people from air and water pollution, odors, chemicals, stress, and more. Compared to wood charcoal, bamboo charcoal is more porous, with countless microscopic pores and a hexagonal shape resembling a honeycomb. When carbonized, there is a significant difference in adsorption capacity, exceeding 600 square meters per gram, which is more than three times the surface area of wood charcoal. The surface area of bamboo charcoal measuring about 30 centimeters is said to exceed 10,000 square meters, comparable to the size of a soccer field. Therefore, the humidity-regulating and deodorizing effects due to its porous nature are improved by more than 5 to 10 times compared to wood charcoal.

The application is extremely simple; just mix with a specified amount of water (mixing machine required) and apply two coats with a brush or roller (spraying is also possible). It can be applied to wood, concrete, metal, expanded polystyrene, and more (no primer or sealer needed). Verification of the application can be easily done with a tester (the training for application takes one day). Seven Industries Co., Ltd., Asahi Wood Industry Co., Ltd., and Shimamura Wood Co., Ltd. can ship pre-cut materials that have been coated.

Factory coating condition
-
It is the same as regular shipping.
-
By applying it to the base, we create a clean environment that repels mites.
-
If it is a frame construction method, it can accommodate any materials (solid wood, laminated wood) and methods (various precuts, metal fittings, hand-cutting, joints, etc.).
-
It's the same as regular construction!!
-
Measurement section (insulation part) Apply masking tape or similar to create insulation parts. (Multiple locations)
-
Direct application of spray insulation materials such as Aquaform can be performed. Due to its effect of maintaining a constant humidity level, it protects wood throughout the four seasons. Additionally, even when exposed to water from leaks or rain, it does not penetrate the wood. It keeps the wood's moisture content constant (below 20%), protecting it from fungal growth and deterioration (internal humidity regulation). The coating surface is hydrophilic, but it does not penetrate the wood (external humidity regulation).
