Indian indoor stadium delivers on green initiatives
Design and and energy-saving measures at an indoor sports arena and aquatic centre in the city of Hassan in Karnataka, southern India are being acknowledged as the most innovative in the country.
The Hasanamba Stadium features a range of green initiatives, using advanced techniques in lighting, ventilation and roofing.
The facility includes a basketball court, three badminton courts, two table tennis courts and an international standard transparent squash court – the first transparent squash court in Karnataka as well as a 25 metre swimming pool.
At least 40% of the venue’s wall is used for ventilation so that there is no need to switch on lights during the day time. At night, lighting comes from single LED lights –rather than multiple LED fittings.
In addition, turbo exhaust fans fixed to the roof keep the atmosphere inside always cool, no matter what the temperature outside is.
The roof was cast using a lightweight alloy of iron and aluminium, which does not rust.
Hassan Deputy Commissioner Naveen Raj Singh, a graduate in civil engineering, designed the structure and he believes that using single LED lights is a world firt for an indoor stadium.
Sigh states “many have used multiple LED lights, but nowhere has single LEDs been utilised.
“Hassan-based Hamshine Electronics has developed the single LEDs and the company has applied for patent for the product.”
The LED lights have a life span of 50,000 hours and although their initial cost is high compared to conventional lighting, within two years the invested amount is earned back in terms of saved energy and durability.
Singh explains “had we gone for the conventional lighting system, we would have required power of 110kw whereas now we have managed with only 10 kw. Moreover we have installed UPS with eight hours back-up.”
The 25 metre six-lane swimming pool at Hasanamba Stadium, is one of just a handful of public pools in India, and is cleaned using Ozone treatment and heated with solar energy.
Commenting on this innovation, Singh concludes “for the first time in the country we are heating water using solar energy.”
In addition, the district administration does not depend on public supply of water for the swimming pool as a rainwater harvesting system has been installed and through that water sufficient for the pool and wash rooms is made available.
