Revealed through outstanding entries in The Emerson Cup – India and Southeast Asia awards, the region is positioned as one of the leaders in creative energy-saving concepts.
The practice of green building results in a range of environmental, economic and social benefits. It helps countries save precious resources, businesses to reduce operating costs, enables people to live in healthier, more environmentally sustainable homes, and much more. In countries like India and parts of Southeast Asia, the construction industry is one of the largest economic activities contributing to development today, witnessing tremendous growth in the building and construction sector. Fast rising income levels are leading to lifestyle changes for various sections of the society. While this is a healthy trend, it is putting enormous demand on resources – like energy, water, materials, etc.
Fortunately, India, Thailand, Indonesia and some of the other Southeast Asian countries realize that it is increasingly important to adopt energy-efficient solutions in construction. The HVACR industry makes a significant contribution to the green building movement with opportunities for improvement in energy efficiency and indoor air quality. The Emerson Cup – India & Southeast Asia annual awards organized by Emerson Climate Technologies to recognize outstanding innovations and energy-efficient design in the air-conditioning and refrigeration industry, receives a high level of entries from this region every year revealing that it is ahead of the curve in green energy thinking.
The Emerson Cup 2012 award ceremony, celebrating its 5th anniversary, was held on October 31, 2012 at Hyderabad city, Andhra Pradesh, India during the 10th Indian Green Building Congress (IGBC). The winning entries displayed impressive innovations in building design and HVAC. The Emerson Cup 2012 had four award categories – New Building, New Building – with Emerson Technologies, Retrofit Building, and Students (Engineering & Architecture).
Energy Commission Diamond Building (Putrajaya, Malaysia) won the Excellence Award under the New Building category for some of its unique features. Designed by Primetech Engineers Sdn Bhd, this building enjoys chilled water supply from gas district cooling. With OTTV fairly low at 35 W/m2K, it is getting renewable energy from photovoltaic, uses recyclable materials, and applies radiant cooling with thermal mass storage, leading to powering up this new structure with less than 10% of its development cost! They also have a rain water harvesting provision that saves more than 70% of water usage.
Another highly innovative project that won an Excellence award was the retrofitting of Hotel Jaypee Vasant Continental (New Delhi, India). With water cooled screw chillers (capacity: 285TR X 3), this 30-year old hotel optimizes air-conditioning systems within the prevailing constraints. Various energy saving measures were implemented for the best energy efficiency without compromising guest comfort. This project is enjoying an attractive ROI ranging as low as 1-3 years.
One of the projects that stood out was the Holy Stadium (Indonesia) that won the Excellence award in the New Building – With Emerson Technologies category. This building has a 1,152HP package system installed with Copeland Scroll™ compressors. Some of the key project highlights were – 25-30% heat gain reduction by using passive design concept “shell and core building”; Jet nozzle installed to cool the occupant area; Air-ducting eliminated by 80%; Total cooling load reduced by 20%; Applied active heat-pipe air-conditioning with scroll compressor.
The Emerson Cup 2012 also awarded a Special Mention to a special sample project called ‘Prana’ by renowned architect Sharukh Mistry of Mistry Architects that was highly appreciated by the independent judging panel for its uniqueness. According to Mr. Mistry, Prana is a beautiful name which means “Life Energy, Life Force – the magic that we take for granted”. Prana is a green initiative by the Indian Society of Heating, Refrigeration and Air-Conditioning Engineers to showcase the latest green technologies like scroll chillers and radiant cooling. In this project, an Earth Air tunnel system is demonstrated, where 72 meters of underground piping is helping this home-office draw cooled fresh air from the ground underneath through air ducts that are hardly visible. It has rain water harvesting facility and low water toilet fittings. Part of the power is being generated through solar PV cells of 3KW.
There have been many such winning entries at The Emerson Cup awards over the course of last five years. Detailed case studies can be viewed at:
