Conditions necessary and sufficient to achieve the desired results determined.パラメーターParametersパラメトリックスタディ（因果律）。パラメーターの組合せでできる形を全ケース計算し、十分な結果の形を採用する。Parametric analysis (causality). Calculate all possible shapes produced by sets of parameter combinations and utilize those that fulfill the requirements.Phase 03最適形状創出／製造検討Producing the optimal shape/ Manufacturing considerations基準形状基準形状Standard shapeStandard shape基準形状と遮蔽すべき基準形状と遮蔽すべき直射日光の交点直射日光の交点（交点部に遮蔽物を残す）（交点部に遮蔽物を残す）Intersection of the Intersection of the standard shape and standard shape and direct sunlight to be direct sunlight to be shieldedshielded底面の交点以外は遮蔽に底面の交点以外は遮蔽に寄与しないので穴として開放性が向上寄与しないので穴として開放性が向上Visibility is enhanced (by adopting Visibility is enhanced (by adopting a specific aperture design), since a specific aperture design), since only the intersection at the base only the intersection at the base of the unit contributes to solar of the unit contributes to solar shieldingshieldingEnvi-lope01の開発プロセス｜Envi-lope 01 Development Process日射を遮蔽するために最適ななべ底の穴の形状を太陽の軌道からデザイン。町工場とのコラボレーションによるものづくりの工夫で、画一的な大量生産でも、一品生産でもないマス・カスタマイゼーションを実現した。The shape of the hole in the bottom of each circular unit was determined for optimal solar shielding based on the relative position of the sun. We created a mass-customization process that is neither mass production nor one-off craftwork, collaborating with a local manufacturer.敷地固有の日射の分析Site-specific solar radiation analysis周りの建物による影（黒）をすり抜けて窓まで到達する直射日光を分析。Analysis of direct sunlight reaching the windows, accounting for shade produced by surrounding buildings (shown in black).A × B × C少ないプレス加工で合理的に製造できるなべ型の基準形状の底部に、日射を最適に遮蔽する固有の穴形状をデザインSpecific aperture shapes that could be produced using a minimal amount of presswork were designed for the base of the circular units for optimal solar shielding結果（目標）Result (target)結果Result 1: The design involved curving the edges of the metal plates in order to prevent them from breaking during the manufacturing process and leaving a burr at the top in place to streamline costs.2 : Extra thin steel sheets and extra fine stainless steel wire were used to minimize on materials and reduce CO2 emissions during manufacture. They cool easily without accumulating heat and are effective in heat-island reduction.161 : 加工時に金属板が裂けないようエッジにアールをつけ板厚の最小化を図ったこと、また通常は切り落とす頂部のバリをコスト合理化のため残したことがデザインにつながっている。2 : 極薄鋼板と極細のステンレスワイヤーで構成し、部材量を最小化し製造CO2の低減も図っている。熱を溜めずに冷えやすく、ヒートアイランド現象抑制にも効果的。：×
