`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.
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.

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.
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.
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.
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.
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
