IRICEN obtained 61 points.
The Indian Railways Institute of Civil Engineering (IRICEN) designed its administrative headquarters as a green building to reduce energy demand and optimise resource usage. The facility is also intended to spread awareness of environmental issues among Indian Railways engineers.
The building is actually utilised in the curriculum for trainee officers at IRICEN. Trainees gain an in-depth understanding of the showcase facility during their studies, helping them to promote green concepts throughout the country.
Crisil House is designed to use recyclable, renewable and locally available materials to reduce its carbon footprint. It also has a large green cover and roof garden to minimise CO2 emissions. The structure allows in sunlight while keeping out heat, thus sharply reducing electricity consumption.
At the operations level, Crisil House has consolidated its data centres through the use of virtualisation technologies. This has allowed it to reduce the number of physical servers by 75%. It has also provided an enclosed space and focused cooling dedicated to the servers.
Marks and Spencer is a major British multinational retailer specialising in clothing, home products and luxury food items. Its Delhi store boasts a host of sustainable features, including heat transmitting glass which cuts UV ray penetration by 90%, helping to stabilise temperatures.
It is also equipped with solar reflective tiles which work with its Energy Star certified equipment to keep the interior cool. Additional green features include rain water harvesting, dedicated recycling bins and the use of rapidly renewable raw materials such as engineered wood.
This project called for a comparison of water-cooled package and air-cooled systems. Water-cooled units can effectively control individual zones if centralised controllers are installed. However, they require a compressor pump and power source plus a cooling tower and boiler. Air-cooled systems can also easily turn on and off to control zones and have fewer additional requirements.
Yamuna is a corporate office facility owned by the Kirloskar Brothers Limited. The company has endeavoured to create one of Pune’s most sustainable buildings, even including a zero discharge water system. The building is designed to achieve the lowest possible power consumption and CO2 emissions while allowing the maximum amount of natural sunlight to enter.
Yamuna received 13 LEED points for its air conditioning and refrigerant system. It was able to achieve the required EER, thanks to its selection of water-cooled VRV. Daikin inverter technology maintains high efficiency during the partial load conditions in which air conditioners usually operate.
