柱の外側にOSB合板（筋交いの代わり）が張られ「箱」としての強度が増した「発寒の家Ⅳ」次は札幌版プラチナ水準に必要な壁断熱を行います。
`Hassamu House IV'' has OSB plywood (instead of braces) placed on the outside of the pillars to increase the strength of the ``box.'' Next, we will perform wall insulation required to meet the Sapporo Platinum standard.
当事務所の一般的な300ｍｍ断熱の家は外部の付加断熱がＧＷ（グラスウール）14ｃｍですが、「発寒の家Ⅳ」ではＧＷの倍の性能を持つフェノールフォーム（板状断熱材）で１２ｃｍの断熱を行います。壁の中に充填されるＧＷと合わせると、概ねＧＷ350ｍｍ相当の壁の断熱となります。
Our office's typical 300mm insulation house has 14cm of additional external insulation made of GW (glass wool), but in `` Hassamu HouseIV'' we have added 12cm of phenol foam (plate-like insulation), which has twice the performance of GW. Perform insulation. When combined with the GW filled in the wall, the insulation for the wall is approximately equivalent to GW 350mm.
２階のテラス部分の付加断熱です。
こちらが付加断熱の断面になります。90ｍｍ＋30ｍｍで120ｍｍとなります。
This is the cross section of the additional insulation. 90mm + 30mm = 120mm.
2009年から北海道に相応しい断熱水準を見つけるために取り組んできた300ｍｍ断熱プロジェクトですが、ここ14年間でほぼ必要な事柄が明らかになってきました。
The 300mm insulation project has been underway since 2009 to find an insulation level suitable for Hokkaido, and over the past 14 years, most of what is needed has become clear.
結論から言えば・・現在一般的な新築の壁断熱であるＧＷ換算で13～15ｃｍ程度の断熱厚では冬はもちろん夏もあまり有効ではなく、特に電気代や燃料費が高騰する2023年現時では住まい手に取ってかなり厳しい経済的負担となるということです。
In conclusion, the wall insulation thickness of 13 to 15 cm (GW equivalent), which is currently common in new construction, is not very effective not only in winter but also in summer, especially in 2023 when electricity and fuel costs are skyrocketing. This places a considerable financial burden on residents.
その一方で、断熱厚を増し必要な気密性能と窓の性能を整えれば、簡単に光熱費が半分から場合によっては1/3程度にまで減ります。
さらにこの家のように壁面太陽光と蓄電池を加えれば災害時も平時も非常に安心度は高まります。自分も歳を重ねてきて・・北国で生きて行く上で、冬の温かさ、夏の涼しさのような室内の居心地は毎日を健全に前向きに生きる上で欠かせないものだと感じるようになりました。
On the other hand, by increasing the thickness of the insulation and providing the necessary airtightness and window performance, you can easily reduce your utility costs by half, or even one-third in some cases.
Furthermore, if you add solar panels on the walls and storage batteries like in this house, the level of security will be greatly increased both in times of disaster and normal times. As I get older, I feel that while living in a northern country, indoor comfort, such as warmth in winter and coolness in summer, is essential to living a healthy and positive life every day. became.
穏やかな室内環境は血圧も安定しますし家中から寒がりな家族がいなくなります。/笑、その結果・・外に出かける余裕が生まれ、今まで憂鬱でしかなかった寒さや雪を楽しめるようにもなります。室内から眺める吹雪もしんしんと降る雪も、いつまで見ていても飽きない地域の大切な情景に変わります。
300ｍｍ断熱に取り組んでみて色々な収穫がありましたが、中でも最大のものは、家の作りようで、地域を愛して暮らせる毎日を得られるということです。北海道に住まう人の多くが、長年悩んできた冬を肯定的に見ることができる。まさに今の時代に求められる自己肯定感の復活・・もちろん燃費もお値打ですが/笑
A calm indoor environment will stabilize your blood pressure, and your family will no longer be sensitive to cold. /Lol, as a result...I can afford to go outside and enjoy the cold and snow, which used to be depressing. The blizzard and falling snow that you can see from indoors will turn into important scenes of the area that you will never get tired of seeing.
I gained a lot of benefits from working on 300mm insulation, but the biggest one was that I was able to spend my days loving the community, just like building a house. Many people living in Hokkaido are now able to look at winter in a positive light, something they have been worried about for many years. This is exactly the kind of self-affirmation that is needed in this day and age...of course, the fuel efficiency is also worth it/lol
