Turnkey solution to Wind Induced Noise in High Rise Building:Mahindra Windchimes Residential Tower01and02,Bangalore

Wind Induced Noise issues

Mahindra Windchimes is a high-rise residential complex situated on the outskirts of Bangalore, directly exposed to winds from the Bannerghatta reserved forest area. Residents have reported significant acoustic disturbances in the reception and common areas on the ground and first floors of Towers 01 and 02. To address this concern, Mahindra Life Space Developers Limited has engaged Niharika Computational Engineering Solutions Private Limited (NCES) for a comprehensive engineering project. NCES is tasked with conducting an in-depth site investigation and formulating a solution to mitigate the acoustic noise issue while preserving the integrity of the existing civil structures. The NCES team has performed extensive site investigations, created a 3D CAD model of the affected floors, and conducted computational fluid dynamics (CFD) analysis exploring various options to resolve the noise problem. Throughout the project, the NCES team maintained ongoing communication with the Mahindra Life Space Developers team and the architect, Morphogenesis. A proposed solution that does not interfere with the existing civil structure has been submitted for implementation.

RESIDENTIAL TOWERS 01 AND 02

Newly completed residential Towers 01 and 02 are now fully occupied, while construction continues on the remaining towers. Residents of Towers 01 and 02 have reported significant noise disturbances. The objective is to identify a comprehensive solution to alleviate these noise concerns without compromising the integrity of the existing civil structure, which presents a unique challenge. Additionally, any proposed solution must receive explicit approval from the architectural team, as the aesthetic considerations are crucial for the towers. The NCES team has conducted an analysis of airflow patterns using Computational Fluid Dynamics (CFD), taking into account various wind directions. The findings from the CFD analysis, combined with our extensive experience in practical fluid dynamics, have allowed NCES to present several implementation options aimed at resolving the noise issues.

Our Collaborative Work Culture

To address the noise concerns, the solution must consider practical limitations, as the Tower has been fully constructed and is currently occupied by residents. The approach devised by NCES will maintain both the structural integrity and the architectural design. The NCES team has taken these constraints into account and has proposed three to four implementation options in collaboration with the architectural team. This demonstrates our capabilities and commitment to a collaborative work environment.

The NCES team dedicated significant time on-site, collaborating closely with the Civil Engineers from Mahindra Life Space Developers to create a 3D CAD model necessary for CFD analysis. The completed 3D model has been reviewed and approved by the Engineering team at Mahindra Life Space Developers. CFD mesh with a cell count of around 28 million Poly Hex core elements is employed for CFD analysis.

CFD analysis is conducted for various wind magnitudes and directions, utilizing climatic data. This analysis is performed multiple times for different design alternatives aimed at mitigating the noise problem. As a result of the CFD analysis, three to four options are developed and presented as the final deliverables.
