Stage1 Part1 Example Conceptual Mass Forms by Flexing One Input
Explored ONE World Trade Center design: Requirements were carefully aligned: 2.5M -3M sqft of gross floor area created, plan view construction area of 984ft * 328ft, no taller than 755ft (capped it to 705ft for rooftop MEP equipment, etc), narrowing to the top to make it financially feasible. The parameter used to flex is “Tower Top Ratio”, which is the length of four sides on the Top View, kept when corner cut on four edges. Surface efficiency for alternative 1 was better than 7 because the surface-to-floor ratio was lower, which might have been used in exploring the design for ONE WTC.
Stage1 Part2 Create Own Conceptual Mass Form and Test It
Explored Base & Mid Hexagon to Top Circle design: Requirements were carefully aligned: 2.5M -3M sqft of gross floor area created, plan view construction area of 984ft * 328ft, no taller than 755ft (capped it to 705ft for rooftop MEP equipment, etc), narrowing to the top to make it financially feasible. The parameter used to flex is the “Diameter” of the top circle, which is essentially the same idea as the Tower Top Ratio, specifically stated for the shape of Part 1. Surface efficiency for alternative 1 was now slightly worse than 7, due to a slightly higher surface-to-floor ratio, which may not affect the decision. The design was created to be more efficient in terms of surface-to-floor ratio with a relatively round floor shape, but did not exceed that of the Part 1 shape, likely due to the tree root bottleneck design.
Point to Ponder: What’s the advantage of exporting the values to Excel? - I think Excel export is much more productive when in need to search at a high granularity. For instance, exploring the optimal design for the targeted gross floor area would be one way to support the project to pencil.
