福島県大田村・現在の伊達市から1899年（明治31年）に集団移住した人々。
移住団長・菊田熊之助氏が移住の「米飯地区」に野桑が繁茂している様子を見て
団員に養蚕を奨励したとされる。
そもそもが大田村は養蚕が盛んだったという。
北海道庁との集団移住話合いの中で、そうした「好適地」が推奨され、
その事業目的が優勢でこの地を選択したものと思える。
集団移住者のなかにこの養蚕民家の建て主・松浦繁松氏がいた。
下の写真は当主・繁松氏の６男、勘助氏。移住当時16才だったという。
撮影写真は昭和32年で74才当時のものだというが、
養蚕の百姓（あらゆる仕事を自力で行う、という意味）らしく
建築工事を精力的に行っている。これで74才とはなんとも若々しい。
凛々しい鉢巻き姿には克己心が表出しているように思う。
昔の人はそもそも鍛え方がハンパではない。
養蚕は蚕自体の生態の把握、その最適化に努める必要があるのはもちろん、
そのためには「建築環境・室内気候環境」保全に繊細な技術が不可欠。
この写真の様子からはそれこそ養蚕にかかわるすべての作業、
とくに建築作事についても大工任せにしない気概を感じる。
蚕の成育状況、その製品品質に建築は直結していたことから、
つねに工事で「手を入れて」いたに間違いない。
「もうちょっと暖房の効率を良くするには、屋根の萱を増やすか・・・」
「２階の開口部からの日射導入をもっと増やすべきか」
など、それこそ製造工場維持管理のように大工仕事に当たっていたと想像。



氏の事跡を伝える情報は不明だけれど、
たぶん農閑期には出稼ぎで大工手間仕事を行っていたに違いない。
近在の都市、旭川で棟梁に指揮される大工仕事から
見よう見まねで大工技術をウォッチして体得したことだろう。
その技量向上がそのまま自分の養蚕業稼ぎの生産性向上に直結する。
復元された養蚕民家のディテールには武骨ながら
丹精が込められていると伝わってくるモノがある。
開拓期の北海道では全国から集まってきたそういう人々の熱気が
渦巻いていたことが想像される。空気感が熱い。
余談ながら、わが家家系でも祖父は1905年（明治38年）に広島県福山から
出身地の縁者を頼って北海道栗沢町に一家を挙げて移住した。
もともと家業は商家だったことから新天地でのチャレンジに積極的で、
この松浦氏同様、周辺での豊富な野桑の繁茂ぶりを見て
養蚕にも手を出していたという。
しかし養蚕業の技術蓄積は十分ではなくそれは断念した。
この時代、さまざまな場所で必死の挑戦が果敢に行われていたのだろう。
祖先の息づかい、時代の空気感がこの養蚕民家から立ち上ってくる。
素晴らしい開拓者魂がこの建築には込められている。
松浦さんの表情に迷いは一点も感じられない。
翻って現代、自分自身を省みて深く教えられるものがある。・・・

Transplanting sericultural construction techniques from Fukushima to Hokkaido.
Management and operation of sericultural private houses, including carpentry and construction. The goal of indoor climate control technology. Ingenuity and ingenuity while utilizing traditional construction methods. The building is a pioneer building.

A group of people emigrated from Ota Village, Fukushima Prefecture, now Date City, in 1899 (Meiji 31).
It is said that Kumanosuke Kikuta, the leader of the emigration group, saw wild mulberry trees thriving in the “Yonei area” of the emigration
He is said to have encouraged the members of the group to grow silkworms.
Sericulture was said to have flourished in Ota Village in the first place.
In the group emigration discussions with the Hokkaido Government, such a “suitable site” was recommended, and
It is likely that this site was selected because of the predominance of the business objectives.
Among the emigrants was Shigematsu Matsuura, the builder of this silkworm-raising house.
The photo below shows Shigematsu’s sixth son, Kansuke. He was 16 years old at the time of emigration.
The photo was taken in 1957, when he was 74 years old.
He is a sericultural peasant (meaning that he does all kinds of work on his own).
He was energetically engaged in construction work. He was 74 years old, which is very young.
His dignified appearance in a padded kimono seems to express his self-sacrificing spirit.
People in the olden days were not so hardy in the way they worked out in the first place.
Sericulture requires an understanding of the ecology of the silkworms themselves and efforts to optimize it.
For this purpose, delicate techniques are indispensable in preserving the “architectural environment and indoor climate environment.
From this picture, it is clear that all the work involved in sericulture, especially the construction work, is entrusted to a great extent.
The picture shows that the silkworm farmers do not leave all the work related to sericulture, especially the construction work, to the carpenters.
The construction work was directly related to the growth of silkworms and the quality of their products.
The construction of the silkworm farms was directly related to the growth of silkworms and the quality of their products, so it is certain that the workers were always “tending” to the construction.
The building was always being “worked on.” “To make the heating a little more efficient, we should increase the amount of roofing shade…” “The daylight from the second-floor opening should be more efficient,” said the owner.
“Should we increase the amount of sunlight coming in through the second-floor openings?
I imagine that they were doing carpentry work as if they were maintaining a manufacturing plant.

Although there is no information on his whereabouts, he must have worked as a migrant carpenter during the off-season.
He must have worked as a migrant carpenter during the off-season.
He probably learned his carpentry skills by watching and learning from the master carpenters in Asahikawa, a nearby city, and by watching and learning from them.
He must have learned carpentry skills by watching and learning from the master carpenters in Asahikawa, a nearby city.
The improvement of his skills directly leads to the improvement of his own productivity in the sericultural industry.
The details of the restored silkworm farm houses, though rugged, are conveyed with great care.
The restored silkworm-raising houses, while rugged in appearance, convey the sense that a great deal of care and diligence went into their construction.
In Hokkaido during the pioneer period, the enthusiasm of people from all over the country was swirling in the air.
Hokkaido during the pioneer period. The atmosphere was hot.
As a side note, in my family, my grandfather came from Fukuyama, Hiroshima Prefecture in 1905.
He and his family moved to the town of Kurisawa in Hokkaido, Japan, with the help of relatives from his hometown.
Originally, the family business was a merchant family, and they were eager to take on the challenges of a new land.
Like Mr. Matsuura, he saw the abundance of wild mulberry trees in the area and took up sericulture.
The family was originally a merchant family and was willing to take on new challenges in new places.
However, he gave up sericulture because he had not accumulated enough technology.
In this period, desperate attempts must have been made boldly in various places.
The breath of the ancestors and the atmosphere of the times rise up from this sericultural house.
The wonderful pioneer spirit is contained in this architecture.
There is not a trace of hesitation in Mr. Matsuura’s expression.
In retrospect, I am deeply impressed by the way he reflects on his own life today. The building is a pioneer building.

45度軸線を振って、空間に変化を与えている家その２です。
上の写真はその特徴が表現される玄関の様子。
斜めに入ってくるのですが、その動線には２方向が用意されて
２番目の写真のように家族のための靴の収納ボックス土間空間への
移動がスムーズに計画されている。
わたしどもでは北海道の住宅見学機会が当然多いのですが、
現代住宅での変化で大きいのはこの玄関土間の拡大傾向。
統計のようなものは参照したことがありませんが、
北海道住宅は積雪寒冷という条件によって外部と内部の間の
「緩衝地帯」の有用性が高まるということは理解できる。
当たり前ですが、吹雪などに襲われてようやく家にたどりついたら
防寒衣類や防寒靴などの重装備を着脱する必要がある。
そういう生活動作について当然ながら動線計画が豊かになる。
最近本州地域では高断熱住宅で除湿機能への注目が大きくなっています。
それは向かうべき住性能の当然の方向だと思いますが、
対比的に言うと、空気の乾燥している北海道ではむしろこういう
生活動線的部分での変化要因が高いように思います。
そしてその空間デザインについていろいろな試行が繰り返されている。
多くの場合には「オモテ」動線に対して、「ウラ」動線として
家族専用の水回りなどと連動していく動線計画が盛り上がっていく。
オモテ動線は古民家などに見られる「ハレ」空間動線と似ている。
ただし、格式的な表座敷空間といったものではなく
現代的なリビング空間として家の雰囲気を表現するといった志向性。
モデルハウス住宅でこういう明確な志向性を表現している。
合理志向の北海道人のイマドキの生活感覚を受け止めている。



さて45度軸線を振ると扱いに困る空間ができる、というポイント。
こちらの上の写真は２階階段上がり口に隣接したトイレ。
前面の壁は45度傾斜角度のままですが、トイレドアはこれも45度振れている。
さてどうするか、で、ここではドアの前に不整形の曲面開口部。
そして階段手すりもなだらかにカーブさせている。
内心、おお、うまいと歓声を上げさせて頂いた（笑）。
見学する最初からの探索動機に変化球が返ってきた感覚。
ただやはりドア前の45度空間は不思議な場所になるので、
個人的には姿見の鏡なんかはどうかと思っていました。
この場所が一番の不整合性を見せているくらいで、あとはプランとして
非常に上手にまとめられている。そしてこの場所もある意味、
たいへん個性的な空間になっていて、住む人にイマジネーションを与える。
姿見空間としてふと自分を顧みる空間っていうのもオツ。
なにもかも合理主義ではない象徴的空間なのかも。

ということで、久しぶりの住宅集中見学in旭川は、刺激に満ちていました。
これからも現代住宅の変容に注目していきたい。

Spatial design is a glimpse of modern life Asahikawa 2022 House Building Exploration – 11
Home and countryside in a harsh climate and living conditions. Focusing on the entrance earthen floor as a buffer zone. And where to drop the 45-degree plan. …….

This is house No. 2, where the 45-degree axis is swung to give a change to the space.
The photo above shows the entranceway where this feature is expressed.
It comes in at an angle, but the flow line has two directions to provide
The second photo shows the shoe storage box for the family members.
The second photo shows a shoe storage box for the family and a dirt floor space.
We have many opportunities to visit houses in Hokkaido.
The most significant change in modern houses is the expansion of the entrance earthen floor space.
I have not seen any statistics on this, but
Hokkaido’s cold and snowy climate has increased the usefulness of the “buffer zone” between the outside and the inside of the house.
It is understandable that the usefulness of the “buffer zone” between the outside and the inside increases due to the cold and snowy conditions of Hokkaido housing.
Of course, when you finally get to your house after being hit by a blizzard, etc.
It is necessary to put on and take off heavy equipment such as winter clothes and winter shoes when you finally arrive home after being hit by a snowstorm.
Naturally, flow line planning is enriched with regard to such life movements.
Recently in the Honshu area, there has been a great deal of attention paid to the dehumidification function in highly insulated houses.
And I think that is a natural direction for housing performance to head in.
In contrast, in Hokkaido, where the air is drier and drier, this kind of change is more likely to occur.
In contrast, in Hokkaido, where the air is drier, I think that the factors that cause changes in the living environment are rather high.
Various attempts have been made to design such spaces.
In many cases, the “back” flow line is linked to the “front” flow line.
In many cases, the “back” flow line is linked to the “front” flow line, which is linked to the family’s private water area, and so on.
The “omote” flow line is similar to the “hare” flow line seen in traditional Japanese houses.
However, it is not a formal front room space.
The omote is oriented to express the atmosphere of the house as a modern living space.
This house as a model house expresses this kind of clear orientation.
The house is in tune with the modern lifestyle of the rational-minded people of Hokkaido.

Now the point where, if you swing the axis 45 degrees, you have a space that is difficult to handle.
The photo above here shows a toilet adjacent to the second floor stairway landing.
The front wall is still at a 45-degree sloping angle, but the toilet door is also swung 45 degrees.
So what to do, and here is the irregularly shaped curved opening in front of the door.
And the stair railing is also gently curved.
I was inwardly cheering, “Oh, that’s good” (laugh).
(Laughs) I had the feeling that my initial motivation to visit the building had been changed.
However, after all, the 45-degree space in front of the door is a mysterious place.
Personally, I wondered about something like a mirror for a figure mirror.
This place shows the most inconsistency, and the rest is very well put together as a plan.
The rest of the plan is very well organized. The rest of the plan is very well put together.
This place is a very unique space that gives imagination to those who live here.
It is also nice to have a space to look back at oneself as a space to look at oneself.
It is a symbolic space that is not rationalistic in any way.

So, the first intensive housing tour in Asahikawa in a long time was full of stimulation.
I would like to continue to pay attention to the transformation of contemporary housing.

田園住宅というコンセプトの旭川市東桜岡に建つ家。
日本の場合は、大規模土地開発はおおむね戦後になって
地方からの大都市圏への人口吸引のニュータウンとして作られ、
むしろそれ以前からの都市圏の住宅の方が高級住宅であり、
ニュータウン型の住宅地は現在、存続の危機にさらされている。
一方、欧米住宅地では日本のように住宅本体だけではなく
その立地環境全体がデベロッパーによってプロデュース提示されている。
ユーザーは総合的な「住む」環境を入手する。
住宅供給主体者は基本的には「住環境」全体をユーザーに訴求している。
多くの場合、住宅地はゾーン開発されそのゾーンの中心には苑池があって、
最高級住宅はほぼ一様に苑池に隣接して建てられている。
人間環境としては、そのような自然景観との一体的な環境が優れているという
「公知」が住宅の常識になっているのでしょう。

北海道の場合は都市でも自然環境との融合ぶりが感じられるけれど
そのなかでもこの住宅の立地はさらにその魅力を際だたせている。
苑池と隣接する戸建て注文住宅という世界標準的な好環境が
あたりまえのように実現している。
好立地の上、さらに性能的には世界最先端レベルでしかも完全注文住宅。
この建て主さんのように自然派の好みを完全に実現させている。
北の自然に近接してしかも高性能の注文住宅を建てられるというのは
現代だからこそ実現できる高品位な人間環境だと思われる。
ほんの150年ほどの住宅史で住まい手の夢が実現している。
そして北海道では他の地域でも多様なシアワセの住環境が
それぞれの風土のなかで実現していると思う。
作り手のレベルの高さは比類がない。
本州地区では連日35度を超え高湿な気候の中、室内気温は高断熱で下げても
湿度管理まではエアコン性能だけでは不十分ということも見えてきた。
その蒸暑気候の課題に正面から性能設備進化で立ち向かう動きも見られる。
旭川の冬は厳しいけれどブリザードのなかでもその自然の美しさは
きわだって魅力を放つだろうし、夏場の爽やかさは言うにも及ばない。
地球温暖化が叫ばれているけれど、北海道の夏は比較的低温で低湿度。
冬の外気と戦いながら、夏は爽やかさを全身でたのしむ暮らし方。


Replan誌では昨年薪ストーブ特集を出版したけれど、
感染症に苦しむ社会の中で、全国からの購入希望が寄せられた。
たぶん多くの人々の心に「空間の癒し」の意味合いが強くなっているのではないか。
最近の住環境への希望にはそういう志向性を強く感じる。

そして感染症による閉塞状況から徐々に情報交流が復興していくことが
あらたな経済復興にとっても非常に重要だと思える。
よき住環境の追求がひとつの起爆剤になっていくことを願っていきたい。

Asahikawa 2022: Cutting-Edge Housing that Sympathizes with Nature in the North.
Nature in the north has low temperatures and low humidity. The freshness is unparalleled. The realization of a high quality human environment in relative freedom from the sweltering heat of summer. ……

A house in Higashisakuraoka, Asahikawa City, based on the concept of a rural residence.
In Japan, large-scale land development generally started after World War II.
In the case of Japan, large-scale land development was generally created after World War II as new towns to attract population from rural areas to large metropolitan areas, and the houses in urban areas before that were more luxurious.
In Japan, large-scale land development was generally created after World War II as new towns to attract population from rural areas to large metropolitan areas, and the housing in urban areas before that time was more luxurious.
New town-type residential areas are now in danger of extinction.
On the other hand, in Europe and the U.S., the entire environment of the site is developed by the developer, not just the houses themselves, as in Japan.
On the other hand, in Western residential areas, the developer produces and presents not only the house itself, but also the entire environment in which it is located.
The user obtains a comprehensive “living” environment.
The housing provider basically appeals the entire “living environment” to the user.
In many cases, residential areas are developed in zones, with a garden pond at the center of the zone.
The most luxurious residences are almost uniformly built adjacent to the garden pond.
The best residences are almost uniformly built adjacent to garden ponds.
This “public knowledge” that such an integrated environment with the natural landscape is superior as a human environment has become a common sense for housing.

In Hokkaido, even in urban areas, there is a sense of fusion with the natural environment.
The location of this residence is even more appealing.
The world-standard environment of a custom-built detached house adjacent to a garden pond has been realized as a matter of course.
The location of the house is also very attractive.
In addition to the excellent location, the house is a completely custom-built house with the world’s most advanced performance level.
The naturalist’s taste has been fully realized, as in the case of the owner of this house.
The ability to build a high-performance custom-built house in close proximity to nature in the north is
It is a high quality human environment that can only be realized in the modern age.
The dream of many residents in the past 150 years or so has come true.
And in Hokkaido, many other regions have also realized a variety of beautiful living environments.
I believe that the high level of craftsmanship is the key to the realization of such a high quality human environment.
The level of creativity is unparalleled.
In the Honshu area, where the temperature exceeds 35 degrees Celsius every day and the climate is humid, even if the indoor temperature is lowered by high insulation, the humidity is not controlled by air conditioning alone.
In the Honshu area, where the temperature exceeds 35 degrees Celsius every day and the humidity is high, it has become apparent that air conditioning alone is not sufficient to control humidity.
There is a movement to confront the challenges of the hot and humid climate head-on with the evolution of performance equipment.
Asahikawa’s winters are harsh, but even in the midst of a blizzard, the natural beauty of the area will be extremely attractive.
The freshness of the summer season goes without saying.
Although global warming is being called for, Hokkaido’s summers are relatively cool and humid.
While fighting against the winter air outside, the summer is a time to enjoy the freshness of summer with all your senses.

Though Replan magazine published a special issue on wood stoves last year.
In a society suffering from infectious diseases, we received requests from all over the country to purchase one.
Perhaps the meaning of “healing space” is becoming stronger in the hearts of many people.
I strongly sense such an orientation in recent hopes for the living environment.
And the gradual recovery of information exchange from the blockage caused by the infection
I hope that the pursuit of a good living environment will be the catalyst for a new economic recovery.
We hope that the pursuit of a good living environment will serve as a catalyst.

旭川住宅見学記その４、芦野組さんの現場。
長く旭川の新住協活動の中心的存在として活躍の作り手。
高断熱高気密技術とともに個性派建築家とのコラボも多く、
個性派志向の建て主さんからの「指名」も多い。
今回見学の住宅もかなり個性派で、会員企業間での話題も大きかった。

敷地は東旭川の自然、苑池に面している好立地環境。
室内から常にこの湖面を眺めて暮らせるという垂涎の環境です。
やや黒っぽい外観で「なかなかに、っぽいなぁ」と近づいていって
外壁素材が非定型的な形状であることに目が慣れてくる。
「この家の素材はほぼ施主さんからの支給品が多いです」
というコメントが得られました。
芦野組さん自体、自然素材系で建築する住宅が多いのですが、
類は友を呼ぶということか、同じ志向性の建て主さんということ。
木質外皮は規格的に整形せずに「あるがまま」の湾曲ぶり。
まぁ基本的に断熱層・通気層は外壁手前側で成立させているので
外壁材自体は、どのような素材であっても自由度は高くなってくるといえる。
わが家なども外断熱なので木質＋角波鉄板＋煉瓦積みなどと
自由な素材選択・組み合わせで構成してもらった経験があるので
理解はできるけれど、施工上は規格寸法のほうが合理的に成立させやすい。
この建物では軸間に105mm＋付加断熱GW210mmの300mm断熱層。
外壁材を保持させる下地は縦に胴縁45mmが入っているので
鉛直方向での「不揃い」はクリアできるとは思われる。
下見板張りを工法採用しているので、材の不揃いぶりは重ね部分の
工夫で現場対応ということなのでしょう。
外壁材の樹種は北海道産の「トドマツ」木酢塗りで木口部分は
その木の外皮部分がそのまま露出していると見受けられました。
樹皮自体は剥ぎ取られた素材のようです。
見た感じでは長さは一定寸法に収まっていたように思います。
しかし、大工造作は１枚一枚、慎重な作業だったことでしょう。


さらに驚かされたのが、上の写真の正面側の壁であります。
外壁素材はまぁこだわりだなぁ、ということでしたが、
こちらの１面の壁はなんと「ワラ素材＋土塗り壁」で仕上げられている！
え、と思わず問い返したのですが、充填＋付加断熱はワラ断熱500mmとのこと。
建て主さんは自然派木こりとして知られる陣内雄さんの家づくりサークル会員。
〜陣内雄、北海道出身のキコリ・シンガー。歯笛プレイヤー。
葉加瀬太郎と音楽友達。東京芸大・建築科出身。〜
Replanでも以前、ワラの家を誌面で紹介していましたが、
わたし自身は一般住宅の実作で見るのは初めてでした。
通常のGW断熱層との連続性確保は責任施工範囲でクリアさせている。
この外壁施工時にはサークル会員さんが集まって作業したとのこと。
・・・さすが旭川、こだわりもディープです。

Asahikawa 2022 House Building Visit-7
The exterior walls are made of uneven, natural Abies sachalinensis, and one wall is finished with clay and 500mm of straw insulation. The house is bursting with attention to detail. …

Asahikawa housing tour No.4, Ashinogumi’s site.
Ashino Gumi has long been a central player in Asahikawa’s Shinjyukyo activities.
They have been collaborating with many unique architects as well as using high heat insulation and airtight technology.
The houses we visited this time are also quite individualistic.
The house we visited this time was also quite unique, and was the topic of much conversation among the member companies.

The site is favorably located facing the natural beauty of Higashi-Asahikawa, En-ike Pond.
It is a coveted environment where one can live with a constant view of this lake from indoors.
The somewhat black exterior of the building made me think, “It’s quite, like…” as I approached it.
Your eyes become accustomed to the atypical shape of the exterior wall material.
The materials in this house are almost exclusively supplied by the client.”
I got the comment, “I’m not sure.
Ashino Gumi itself builds many houses with natural materials.
It seems that the same kind of people build houses with the same orientation.
The wooden exterior skin is not shaped in a standardized way, but is curved “as it is.
Basically, the insulation and ventilation layers are formed on the front side of the exterior walls.
The exterior wall material itself can be made of any material with a high degree of freedom.
Our house is also externally insulated, so it can be made of wood + corrugated iron sheets + brickwork, etc.
I have experience in having my house constructed with a free choice and combination of materials, so I can understand.
I can understand this, but in terms of construction, standardized dimensions are more reasonable.
In this building, there is a 300mm insulation layer of 105mm between the shafts + 210mm of additional insulation GW.
The substrate that holds the exterior wall material has 45mm of furring strips vertically.
It is thought that “unevenness” in the vertical direction can be cleared.
Since clapboarding is used in the construction method, the unevenness of the material is
The clapboards are made of Hokkaido wood.
The exterior wall material is Abies sachalinensis from Hokkaido, and the wood is coated with vinegar.
The bark itself seems to have been removed.
The bark itself seems to be a stripped material.
The length of the tree seemed to be within a certain dimension.
However, the carpentry work must have been very careful, piece by piece.

Even more surprising was the wall on the front side of the photo above.
The exterior wall material was, well, a matter of taste.
This one wall here is finished with “straw material + clay painted wall”!
I asked him what he meant, but he told me that the filling + additional insulation is 500mm of straw insulation.
The owner of the house is a member of the house-building circle of Yu Jinnai, a well-known natural lumberjack.
~Osamu Jinnai, Kikori singer from Hokkaido, Japan. Tooth flute player.
Music friend of Taro Hakase. Graduated from Tokyo National University of Fine Arts and Music, majoring in architecture. ~Replan
Replan had previously featured a house made of straw in its magazine, but this was the first time for me to see a real house myself.
This was the first time for me to see an actual house.
The continuity with the normal GW insulation layer was cleared within the scope of responsible construction.
The members of the circle got together and worked on this exterior wall construction.
……As expected of Asahikawa, the attention to detail is also deep.

旭川のイマドキ住宅見学、その３軒目は北海道ハウジングさんの構造現場。
北海道の住宅性能的現在地点はいま、北海道庁建築指導課を中心にして
いわゆるZEHの論議からスタートし、その先の2030年、2050年の
世界的な目標基準をどのように地域としてテーマ目標を定めるか、
活発な論議が進行しています。
審議会は国の住宅施策検討の中心メンバーでもある鈴木大隆さんが
本来の道総研理事としての立場から「座長」として主導。
わたしもその論議には参加させていただいています。
今2022年期の集中的論議ではすでに３回ものワーキング会合を開催。
鈴木座長としては「これまでの住宅施策についての北海道の先導的立場を
しっかりとわきまえながら、先人の思いを継承していきたい」という意見。
折に触れてそうしたテーマ意識が表出されて
研究開発主体の北総研をしっかり領導する論議が展開しています。
この10月には国の「住宅月間」中央イベントが札幌開催。
そのタイミングでこの論議の中間結果が発出されていく可能性もあります。

旭川の工務店グループは住宅性能開発では北海道内でも最先端。
本部が旭川にある北総研の研究開発の技術的パートナーとして経験蓄積。
日本でいちばん寒くて、雪も多いという地域特性から
実証検証を研究者と産学協働してきた歴史があります。
新住協活動でも、鎌田紀彦先生とともに最先端技術開発に取り組んできた。
そういう地域です。しかし一方東京都が象徴的ですが
ZEHの最大要素素材である太陽光発電では冬の多雪条件から
屋根面での搭載は非常に困難を伴う地域的ハンディを負っている。
積雪による稼動ロスを「壁面設置」などでクリアするとか、
さまざまな実証検証に踏まえた手法開発が続いてきている。
さらに広い北海道では多様な気候環境に細分化されてもいる。
そういう論議を経て、2050年も見据えた方向性が確定してきている。
北海道住宅局建築指導課からの情報発出を待って
大いに情報発信していきたいと考えています。

この住宅は昨日までご紹介の家と同じ東川の高台の家。
こちらでは木々が伐採された環境になっています。
敷地は広大なので雪は落雪屋根としていますが冬季の利便性を考えて
駐車スペースは屋内に設定している。
3番目の写真がその屋根架構の様子です。
積雪対応をしなければいけないが、カーポートなので柱の類は
必要最小限化する必要があるため、梁組・小屋組はまことに重厚な構造。
積雪対応という意味で構造面でもハンディキャップはある。
まさに「課題の最先端地域」北海道でも最たる地域性。
しかしそういう住宅性能実験地域でもあることで、
作り手たちの先取精神は高いレベル。
どうやったら構造の強化とコストのバランスを取れるのか、
実務家たちの実践的な白熱した論議が交わされていました。

Structure, Insulation, Airtightness, and Heated Discussion: Asahikawa 2022 House Building Visit-5
Hokkaido, a region at the forefront of the issue, is formulating a policy in response to the national declaration on decarbonization and will issue measures for the year 2050. Asahikawa 2022 House Building

The third house on our tour of Asahikawa’s “Imadoki” houses is the structural site of Hokkaido Housing.
The current state of housing performance in Hokkaido is now being discussed by the Building Guidance Division of the Hokkaido Government.
The current state of housing performance in Hokkaido starts with the discussion of the so-called ZEH, and how to set global target standards for the years 2030 and 2050.
How can we set a theme target as a region for the global target standard in 2030 and 2050?
Active discussions are underway.
Mr. Hirotaka Suzuki, who is also a core member of the national government’s housing policy review committee, has been a member of the council.
I also took part in the discussion.
I have also participated in the discussions.
Three working sessions have already been held in the intensive discussions for the current fiscal year 2022.
As Chairperson Suzuki says, “While keeping in mind Hokkaido’s leading position in housing policies to date
We would like to inherit the thoughts of our predecessors while keeping in mind Hokkaido’s leading position on housing policies.
He expressed his awareness of this theme from time to time.
Discussions are being held to firmly lead the North Research Institute, which is the main research and development institute.
This October, the central event of the national “Housing Month” will be held in Sapporo.
It is possible that the interim results of this discussion will be issued at that time.

Asahikawa’s construction group is at the forefront of housing performance development in Hokkaido.
The group has accumulated experience as a technical partner in the research and development of the North Research Institute, which is headquartered in Asahikawa.
The region is the coldest and snowiest in Japan.
We have a long history of collaboration with researchers and industry-academia for verification and validation.
In the Shinjyukyo activities, we have been working with Dr. Norihiko Kamata to develop cutting-edge technologies.
This is the kind of region we have. On the other hand, Tokyo is a symbolic example.
However, as Tokyo is symbolic of, solar power generation, which is the most important element of ZEH, is very difficult to install on roofs due to the heavy snowfall in winter.
The roof surface of solar power generation, which is the most important element of ZEH, is at a disadvantage in the region due to heavy snowfall in winter.
The operational loss caused by snow accumulation can be cleared by “wall mounting” and so on.
The development of new methods has continued based on a variety of demonstrations and verifications.
Furthermore, Hokkaido, a large island in Japan, is subdivided into a variety of climatic environments.
Through these discussions, the direction of the project is being finalized with an eye toward 2050.
We are waiting for the Building Guidance Division of the Hokkaido Housing Bureau to issue information.
We hope to provide a great deal of information on this project.

This house is located on a hill in Higashikawa, the same house we introduced yesterday.
Here, the trees have been cleared and the environment has been cleared.
The site is vast, so the snow is set to fall off the roof, but for winter convenience
The parking space is set indoors.
The third photo shows its roof structure.
The third photo shows the roof structure, which must be able to cope with snow accumulation.
The beam and shed frames are very massive in order to minimize the need for columns.
In terms of snow accumulation, the structure is also at a disadvantage.
This is the most advanced region in Hokkaido, which is truly a “cutting-edge region in terms of issues.
However, the fact that this is also a region that experiments with housing performance has made it a place where the spirit of forward-thinking builders is high.
The creators have a high level of forward-thinking spirit.
How can we balance structural reinforcement and cost?
Practitioners engaged in heated discussions on how to balance structural reinforcement and cost.
