Ruby Mills - Mumbai



0 dislikes

Ruby Mills, the tallest tower in Mumbai, stands as a shining example of modern glazing solutions for energy efficient building. It has the unique distinction of being the first energy efficient building in India in which Ceramic frit and high performance glass have been used. This potent combination has gone a long way in achieving unmatched energy efficiency and design goals, making Ruby Mills the iconic skyscraper that it is.

Design Intent

The aim of the project was not just to be a landmark skyscraper and the tallest Commercial Tower across the Mumbai skyline. More importantly, its objective was to provide a suitable glazing solution for a green-rated energy-efficient office building with extensive use of glass in the envelope. Besides having eco-friendly architecture, the towering façade also aimed at creating unique design sensibilities - a mosaic pattern spread over 30,000 sqms.

The Glass Effect

The Design team from Saint-Gobain Glass collaborated with the energy consultant EDS to provide a customized glazing solution; the company provided facades based on orientation, and worked on the ceramic frit solutions.

The thickness/wind-load analysis and panel design optimization were also done as a part of structural analysis by the design engineers.

After a detailed analysis, the green building glass SGG Envision Magma (SKN 154) IGU was suggested. SGG Envision is a high performance, 5th generation glass that has a high light transmission as well as a very low solar factor.

Envision Magma had a solar Heat Gain Coefficient: 0.26 reduced up to 0.22 (using frit), U-value: 1.5 W/m2K and Light Transmission: 50% (optimized to 30% in glare prone areas)

Key Green Features

The energy efficient building incorporated several green factors, some of which included:

  • 2% daylight factor for 75% occupant areas
  • >90% occupants with outdoor views
  • Adherence to ECBC green building specifications with:
    • Solar Heat Gain Coefficient < 0.25
    • U-value < 3.3
    • Light transmission > 20%
    • Innovations of the project
    • Extensive ceramic frit

The façade had a combination of 30%, 60% and non-fritted panels. 60% and 30% panels were used extensively in the South & West facing façade. Each of the façades had a tailor-made design & density of frit to offer unobstructed views (sans glare) in the vision panels.

Ceramic Frit and External Reflection were designed to complement stone cladding.

Individual panel labeling was done to ensure exact mosaic pattern while installation.

For the first time in India, Ceramic frit was used to achieve unmatched efficiency and design goals. With a customized Frit design, balanced Design & Energy, the high rise building achieved a targeted energy reduction for IGBC - LEED Gold rating.

Integrated solutions offered for safety/low VoC

Extensive Fire Safety solutions through fire resistant glass were implemented.

The Interior applications used lacquered glass and Miralite Evolution (Mirrors), which have a very low VOC content, to increase indoor air quality.
