The Future of Wind and Housing! A Discussion on the Current State of Attics in Japanese Homes.

In this discussion, we explain measures against humidity and condensation in attics, as well as the importance of ventilation. Our company launched the underfloor ventilation system in 1981, and two years later, we introduced the attic ventilation system. Since then, after several model changes, it has become common to adopt it as a standard specification for new constructions. However, through many years of promotional activities, there is an impression that attic ventilation is perceived only as a measure against heat by both businesses and end users. *For more details about the discussion, you can view the PDF materials or related links.

Measures against condensation in summer! Condensation and corrosion within wall structures are often difficult to detect.

In 2020, the "mandatory energy-saving standards for housing" are scheduled to be implemented, and it is expected that Japanese housing will increasingly aim for high airtightness and high insulation. However, at the same time, measures against condensation during the summer must be considered. In a site where glass wool was filled using the 2x4 construction method and a vapor barrier was installed on the interior side, significant corrosion due to condensation occurred. It is believed that the interior became hot and humid, leading to condensation as it was cooled by the air conditioner on the inside. The hold-down hardware also showed white mold, and if corrosion progresses like this, it will pose problems for the durability of the building. This type of summer condensation particularly occurs in regions with high temperatures and humidity, like Japan. Therefore, it is necessary to implement sufficient measures against winter-type condensation while simultaneously preventing summer-type condensation. *For more details, please refer to the PDF document or feel free to contact us.

The reduction rate is approximately 15% to 23%! We confirmed energy-saving effects by ventilating the attic.

This experiment examines the "effect of indoor air conditioning electricity consumption." By ventilating the attic, the reduction rate of electricity consumption during air conditioning operation on sunny days was approximately 15% to 23% (*), confirming the energy-saving effect. Additionally, a comparison of temperatures between the attic, indoors, and the human body using a thermotracer showed that with a ventilation system, the temperature of wooden components such as beams in the attic and the ceiling surface was lower, and the temperature difference indoors was reduced with height. *Varies depending on conditions and the air conditioner's capacity and efficiency. Air conditioning operation time: 16:00 to 22:00 for 6 hours. 【Results of the indoor air conditioning electricity consumption effect experiment】 ■ The reduction rate of electricity consumption during air conditioning operation was approximately 15% to 23% (on sunny days). ■ The energy-saving effect was confirmed. *For more details, please refer to the PDF document or feel free to contact us.

When the moisture content exceeds 20-25%, wood decay is more likely to occur.

We conducted an experiment on how completely dried wood is affected by the ventilation conditions under the floor in a test house. Initially, the moisture content rises as it absorbs moisture from under the floor, but in the case of having a "subfloor ventilation fan" installed, the moisture content of the posts stabilizes at around 20%, as shown in the graph in the image. It can be seen that the moisture content is about 5% lower compared to when there is no "subfloor ventilation fan." 【Test Overview】 <Comparison of Moisture Content in Subfloor Posts in the Test House> ■ Duration: May 24, 2003 - July 27, 2003 ■ Post Size: 105×400mm, measuring 3 posts, the graph shows the average moisture content of the 3 posts ■ Measuring Equipment: Sanko Electronic Research Institute Co., Ltd.

The cause is a large amount of water vapor! The challenge is how to remove humidity and suppress mold and decay.

Foundation insulation is a method of insulating the foundation that faces the outside air. The period when the risk of condensation and mold is highest with foundation insulation is from June to September of the first year after completion. The main cause is the large amount of water vapor coming from the concrete floor. Especially, wood that contains a lot of moisture significantly deteriorates in strength, so it is important to be cautious considering durability against earthquakes and typhoons. As a solution to these humidity problems, our company has developed a dedicated underfloor dehumidifier called "Dry Pro." It effectively eliminates humidity and condensation, and is useful for preventing mold, pests, and decay fungi in the underfloor wooden components. (Patent and design application pending) 【Features of Dry Pro】 ■ Dehumidification capacity of approximately 400-600cc per day on humid days during the rainy season and summer ■ Circulates dehumidified air widely using a blower ■ Quiet design: 45/44dB ■ Standard equipped with phytoncide that has deodorizing effects *For more details, please refer to the PDF materials or feel free to contact us.

After about one month, a drier condition (wood moisture content 12%) was confirmed!

"Dry Pro" is a floor underfloor dehumidifying fan that effectively eliminates moisture and condensation, and is effective against mold, pests, and decay fungi in the wooden parts under the floor. Assuming the early stages of new construction using foundation insulation methods, 36 liters of water were sprayed on the underfloor foundation of each building, and dried wood (cedar) was installed to measure the moisture content of the wood and the humidity under the floor. As a result, the buildings where this product was installed gradually dried out by repeatedly operating the dehumidification process every day, and after about two months, an average of approximately 70% RH dry condition was confirmed even outside of dehumidification operation hours. [Experiment] ■ Test House A - Floor area approximately 10 tsubo - Underfloor with foundation insulation method (Dry Pro installed) ■ Test House B - Floor area approximately 10 tsubo - Underfloor with foundation insulation method (without dehumidifying fan) *For more details, please refer to the PDF document or feel free to contact us.

Under the floor and in the attic... "Invisible spaces" are being reconsidered now The environment surrounding the housing industry has changed significantly in recent years. Rising timber prices, increased costs of equipment, a shortage of skilled workers, and prolonged delivery times are not temporary changes but are becoming entrenched as structural changes in the entire housing industry. Furthermore, in recent years, the global surge in resource prices, the depreciation of the yen, and rising logistics costs have compounded the situation, leading to a generally unstable environment for housing-related materials. What was once taken for granted—that "necessary materials can be obtained immediately when needed"—is no longer a given. Additionally, the construction and equipment industries continue to face a serious labor shortage. In particular, the aging of veteran craftsmen who support the field is progressing year by year, while securing young talent is not easy. As a result, situations such as difficulty in scheduling construction dates, longer waiting periods until construction, and limited availability of contractors in certain regions are increasingly common nationwide. In the housing industry, there is a growing sentiment that "construction plans cannot be made with the same sense as before," whether for new builds or renovations, which is becoming the norm across the country.

Attendance management is something that is expected of every company and should be addressed. When asked, "Are you doing it?" it might be more concerning to hear, "Are you doing it correctly?" which could make some responsible parties feel anxious. You may be using time cards for clocking in, but are unsure about overtime calculations. You might be having employees input data into Excel, but how does that stand in terms of legal compliance? You may be managing paid leave on paper, but there’s no room for double-checking. Employee resignations may be ongoing, but could this be due to overwork...? Why not review the various pros and cons of different attendance management methods and revisit the important aspects of attendance management from the "basics"?

We have released a white paper titled "The Common Points of Attendance Issues Highlighted by the Labor Standards Inspection Office." This document provides a clear explanation of the challenges in attendance management that are likely to be pointed out by the Labor Standards Inspection Office, using specific examples. It addresses operational risks commonly seen in many companies, such as attendance aggregation in Excel, timekeeping management through self-reporting, insufficient management of paid leave, and rounding of overtime hours. Additionally, it introduces points that are often highlighted in inspections by the Labor Standards Inspection Office, such as "objective understanding of working hours," "unpaid overtime," "management of the 36 Agreement limits," and "compliance with the obligation to take 5 days of annual leave." This content can serve as an opportunity for companies that think "there have been no problems so far, so it's fine" to review their operations. Companies considering improving the efficiency of attendance management and strengthening compliance are encouraged to take a look. If you have any additional questions, please feel free to let us know.
