Design Challenges & Approach

Layout of the site was ideal for providing sun path based orientation to the prayer hall and lower hall i.e. longer axis along East-West and adopt an L shaped layout meeting total built up area requirements of the project.

Building design and envelope offered following challenges since most of the structural and internal cooling had to naturally minimize energy consumption and thereby optimize capex and operating costs of hybrid green power generation at site:

  • Architectural designs with no walls or windows should also provide protection against strong winds and heavy rains during monsoon

The building façade has beautiful white GRC jallis (non-conductive) with over 60% openings that offers protection against weather yet enhance ventilation since air undergoes the process of compression & decompression while passing through jali openings.

  • Cooling the terrace floor structure natural way

Terrace floor cooling was done by laying solar heat reflecting white china tiles which reduced the internal temperatures by around 5 degrees centigrade. The terrace floor was designed to have shallow water ponds to cool the roof structure.

  • Design of open spaces on ground level for structural

Ablution water (in Wazu area) and other water bodies, landscaping and lush low level plants have been provided on the ground so as to keep the area around the building cool. More coconut trees were planted around the building to shade the ground and building and thus reduce the solar heat gain. The high canopies of coconut trees still allow breeze all around the building.

Innovative Ideas

The entire mosque both internal and external has been painted white to provide a solemn and ethereal setting. The western façade (Mehrab) has a green wall (vines) which forms the end to the Prayer Hall. These reduce heat gain in the afternoon and provide a lower temperature micro climate. In addition, heavy duty ventury type turbo vents installed on terrace floor discharge internal heat naturally.

A thoughtfully conceived 70ft high minaret of size 10ft x 7ft for Azan (call for prayer) also serves as wind scoop to force down draft of breeze into the prayer halls. It displays calligraphy as also supports the lattice tower structure of wind turbine mounted atop it.

The Bearys Group in consultation with the Trust decided to make a unique contribution to mitigate global warming. It therefore chose not to use power from the State Grid but instead utilize green renewable energy. The place has strong winds during monsoon season but of around 4 m/ sec wind during November to March. The solar insolence is excellent and at its peak during November to March period and it was therefore decided to install hybrid green power having 1.5 kVA wind turbine and 0.6 kVA SPV in phase I and another 4 kVA SPV in phase-II
