The Badriya Jum’A Masjid is the first mosque in the Kodi region of Kundapur, Udupi district. The mosque was re-built in 2016 as an environmentally friendly mosque by implementing measures like Sustainable/Green architecture, Naturally Aspirated/Cooled building, using local construction materials, and integrating renewable energy. The mosque is also the world’s first mosque to receive a Platinum Award in 2016 under the ‘IGBC Green Place of Worship’ rating system.  The design follows Islamic architecture, embracing the rich traditions of Islam while exemplifying modern principles of eco-friendly construction. In 2021, the installed on-site Hybrid renewable energy plant was expanded, making it self-sufficient in terms of its own energy needs as well as catering to the electricity needs of the student hostel during grid outages. The mosque was awarded platinum rating under ‘IGBC Net Zero Energy Building’ in 2022.

Orientation & Architecture

The building plan is L-Shaped with a longer axis along East-West. L-shaped building plan and elevated prayer hall (10 ft), almost open façade on three sides (GRC Jaalis & front teak wood doors have over 60% openings), green wall on western side, high prayer hall ceiling, terrace lined with white China and high reflective white finishes/white marble minimize solar heat ingress.

Ventilation Design

The mosque is a naturally aspirated building. The mosque features visually appealing white GRC (Glass Fibre Reinforced) jaali work on North and South facades, along with teakwood doors adorned with similar jaali work on the East. With over 60 percent openings, the design has enabled cross ventilation, especially capturing the prevailing South West cool sea breeze. These openings act as venturis directing winds into the prayer hall. 

The West facade is adorned with a green wall to protect the West facade from solar radiation and operable windows are installed for cross ventilation. The building also has a uniquely designed 21-meter-high minaret that gradually tapers towards the top. At the pinnacle, there are openings on the South and West sides, functioning as wind scoops and channeling fresh and cool sea breeze directly into the prayer hall.

Black Turbo Ventilators are installed on the roof to create a stack effect and enhance heat ejection from the prayer hall.

Landscaping

Approximately 87 percent of the open space around the building has been carefully landscaped with native grass, plants, and coconut trees. Walkways in the open areas are in laterite, as a measure to reduce stormwater run-off as well as mitigate heat island effect. High thick green canopy of the trees keeps the structure cool. Ablution tanks around the base of the building enhance cooling of the structure.

Materials

The terrace floor is covered with white China mosaic, allowing the surface to reflect solar radiation thereby reducing heat ingress. High reflective finishes, white color paints, and white marble as a measure to reduce heat gains and enhance thermal comfort. Additionally, during demolition and construction, all waste materials were reused or repurposed as walkways, grills, kerbs, pedestals, etc. Use of local thick Laterite blocks for walls & pathways keeps the building cool and connects the building with nature.

Lighting

Lighting has been optimized considering the “almost open” feature of the Mosque. Optimized Light Power Density (LPD) is  0.13 w/sq. ft and only LED light fixtures have been used.

Water

Beary Group, considering water as an essential resource and tribute to nature, ensures rainwater harvesting, collection and re-use in all their projects. Kodi Mosque is situated on the Arabian Sea shore and even though there was no statutory requirement of RWH, the mosque collects entire rainwater from ground & terrace in a well and reuses it.

 The mosque has made use of low flow (1.4 L/minute) water faucets/fixtures and dual flush (6L/3L) WCs.”

Mechanical Ventilation

Vortex fans are used in the prayer hall to enhance both air circulation and thermal comfort. Black Turbo Ventilators evacuate heat from the prayer hall.

The place experiences cloudy weather & strong winds from May to September and bright sun but low wind speeds from  October to April.  Hence a hybrid renewable energy system was designed and installed as the most appropriate solution. The renewable energy system consists of a wind turbine and solar photovoltaic panels (PV) on-site. This system fulfills the energy needs of the mosque while also generating surplus energy. The system at the mosque is off grid.

A 7kW solar PV-wind hybrid system (5.5kW solar PV and 1.5kW wind turbine) has been installed. The solar PVs are installed on the terrace. To maximize energy generation, the wind turbine is positioned at a height of 30m from the ground (Mounted on a 9m tall triangular tower, placed on top of a 21m minaret).
