Enhancing Solar Chimney Design for New Market S1 Building
In the recent New Market S1 building project, TEK1 participated in various design review meetings, provided numerous markups, and involved in finalizing the design. This project involved 11 flats in one of the blocks, each featuring a solar chimney on the backside of the building.
Amendment 1: Addressing Structural Frame Issues
Initially, the structural frame for the solar chimney was composed of two PFCs on each side running between level-1 slab & the roof. One PFC was fixed to the masonry wall with chemical anchors at regular intervals, while the other was anchored to the sides of the slabs at two different levels. However, we identified a 195mm gap between the steel PFC and the slab due to varying opening sizes for the chimney in the level-1 and level-2 slabs in the architectural layout. With this gap, it was not possible to anchor the PFC to the slab.
Through detailed markups and discussions, TEK1 and the structural team agreed to amend the steel frame. UB members were introduced between level-1 and level-2, providing a wider support anchored on top of the level-1 slab. The PFC members were shortened to run between level-2 and the roof, with the PFC and UB connected by splice plates bolted at the top and bottom flanges. This solution effectively addressed the support issue and ensured structural integrity.
Amendment 2: Refining the Top Frame of the Solar Chimney
At the top of the solar chimney, the initial structural drawings provided rudimentary details. With 11 solar chimneys of varying heights and only one section view in the architectural drawings, TEK1 proposed several sketches with different options to achieve the required heights. After receiving finalization from the architect, we collaborated with the structural engineer to discuss supporting the top frame to the rafters. Stubs were introduced at the top of the rafter to secure the design.
Ensuring Smooth Project Flow
TEK1 ensured that these discussions and iterative markups did not disrupt the project’s workflow. While the solar chimneys were under design review, we focused on detailing other areas and supplied drawings in stages. This approach maintained the project’s momentum and avoided delays.
