製品用井戸空調に利用された井水は約40℃の温水となる…①①の温水を製品の加熱殺菌に利用する…②②により17℃まで下げられた井水を利用し、建物前に「水盤」をつくりだしている空調用井戸富士の湧水 第3工場Fuji no Yusui Yamanashi Factory地下水のカスケード利用を実現した「森の中のエコファクトリー」An "eco-factory in the forest" with cascading groundwater富士山麓国立公園地域内に立地するミネラルウォーター製造工場である。周辺の豊な自然環境に調和し、施設運営の省エネルギー化を図った工場—エコファクトリーを目指すとともに室内の居住性と工場の機能性を確保、環境配慮との両立を実現した。既存森林を最大限残しながら工場機能をコンパクトに配置、建物高さは隣接する木々の高さ以下におさえ景観に配慮した。外観は「松林の風景の抽象化」をテーマとし、数色の外装材とタテ型窓をリズミカルに配置し森林風景との調和を図っている。工場のランニングエネルギーは、「エネルギーの地産地消」をテーマに冷房・冷却に地下水を全量利用するとともに、冷熱源不要化空調システムと製造ライン間での熱融通により、製品を予熱することでCO2排出量を36%削減している。建築だけでなく製造設備も含めたランニングを考慮することで、生産施設としては稀なCASBEE-Sランクを実現した。(中楯 哲史)This mineral water bottling plant is located inside the Fuji Sanroku National Park. The aim of the design was to create an "eco-factory" that is in harmony with the richness of the surrounding natural environment, and to reduce the amount of energy consumed during facility operation and balance the environmentally conscious design with interior comfort and factory functionality. A compact layout was used for the factory functions, in order to preserve the existing forest to the greatest degree possible, and the building height was made lower than the surrounding trees to preserve the scenic beauty of the area. The building is designed to resemble an abstract pine forest, with exterior material of several colors and vertical windows placed in a rhythmical fashion to ensure harmony with the surrounding forest. "Locally produced and used energy" was the theme for the energy used to operate the plant. Groundwater was used for all air conditioning and cooling, and heat transfer between manufacturing lines and an air conditioning system that does not require a heating and cooling source were employed to preheat products, reducing CO2 emissions by 36%. The environmental consciousness of both the building and its manufacturing equipment made this one of the few production facilities to achieve the S or highest ranking in Japan's Comprehensive Assessment System for Building Environmental Efficiency (CASBEE).
