地球温暖化問題を背景に、原油の高騰やバイオエタノールの生産拡大、食品高騰など、地球規模のエネルギー問題が身近な生活に影響を与え始めている。建築の分野でもクリーンエネルギーへの関心は日増しに高まっている。その代表的なテクノロジーが太陽光発電だろう。太陽光発電といわれて、まず思い浮かぶのは、屋根の上に取り付けられている、黒っぽい平面状のパネル。設置場所が限定されてしまうし、デザイン的にもバリエーションが足りない。そんな、太陽光発電パネルのあり方を変えそうな技術が生まれようとしている。そのひとつが「球状太陽電池」である。六角形のお椀型のセルの中に球状のシリコンがセットされ、太陽光の入射角が変わってもしっかりと光をキャッチできるようになっている。これによって曲面上にシリコンセルを配置することもでき、集光率も向上される。こうして出来上がった六角形の美しいシリコンセルが、建築と太陽電池の関係を変えるかもしれない。

南米アマゾン川流域に生息するモルフォ蝶は、「生きた宝石」と呼ばれ、世界一美しい蝶と言われている。近年の研究によって、このモルフォ蝶の羽根の色は、色素によるものではなく、羽根表面の不思議な微細構造によってつくり出されていることが明らかになった。われわれの眼には空や海が青く映るように、モルフォ蝶の羽根は光干渉作用により青く発色していた。このモルフォ蝶の羽根の複雑で微細な構造原理から学び、染料や顔料を使用しないで、光により発色する繊維が実用化されている。今回は、人工的につくり出された光発色繊維に秘められたナノテクノロジーについて学ぶ。

The aim of this study is to present a model for urban housing by investigating the dwelling style in which various facilities for daily living are linked; we did so based on an investigation of the residential use of GOSIWON(Quasi-housing) in Seoul. We attempted to clarify the current distribution of GOSIWON in Seoul, the living conditions in GOSIWON, and their locational characteristics in GOSIWON-dense areas. First, we intended to confirm the changes in the distribution of GOSIWON in Seoul. Second, we classified the scale of GOSIWON in Seoul. Third, we examined the type and distribution of GOSIWON in GOSIWON-dense areas with respect to regional characteristics. We undertook the following steps. (1) Using data related to GOSIWON by Seoul Metropolitan Fire & Disaster Headquarters, we confirmed the overall situation regarding GOSIWON in Seoul since 2010 to 2015. (2) To determine the scale of GOSIWON there, we analyzed the registration information of buildings containing GOSIWON. We categorized the type of GOSIWON by comparing the total floor area of the building (data obtained from ledgers) with the area of the GOSIWON. (3) To assess the characteristics of GOSIWON-dense areas in Seoul, we used a list of GOSIWON and created a distribution map. With that, we were able to confirm the location of GOSIWON-dense areas. We clarified the characteristics of such areas by comparing the distribution and the type of GOSIWON from step 2. The number of GOSIWON in Seoul increased more than 1.5 times over a 5-year period starting in 2010. There was an increasing trend in all 25 districts of Seoul; however, the concentration in Gwanak-gu, Dongjak-gu, Gangnam-gu, Dongdaemun-gu, Seodaemun-gu, and Yeongdeungpo-gu was particularly conspicuous. The situation was similar in Sillim-dong, Gwanak-gu, but there were large-scale GOSIWON in Noryangjin-dong, Dongjak-gu. We also confirmed that there were more facilities dedicated exclusively to GOSIWON in Noryangjin-dong than in other areas. In Sillim-dong, which has the largest number of GOSIWON, facilities with GOSIWON of the same size were widely distributed. In Noryangjin-dong, facilities for exclusive use of GOSIWON of various sizes and combined facilities were densely distributed in a relatively small area. By contrast, Yeoksam-dong and other areas were unlike Sillim and Noryangjin-dong in that a relatively small number of large GOSIWON were broadly distributed. In GOSIWON-dense areas, there were no significant differences in the private space in GOSIWON, but there were differences in the shared spaces within GOSIWON. Notably, in Noryangjin-dong, there were many GOSISAENG (examinee of public employee examination); they had study spaces in addition to common areas, such as a kitchens and toilets. We next intend to examine the actual use of regional facilities related to daily life. Our aim is to clarify the use of GOSIWON by residents of GOSIWON-dense areas.
