Individual AC units with energy-saving VRF technology for heritage building with government offices
Solution : MULTI V IV
An uncompromised air conditioning solution with high energy efficiency
Saving in power consumption is more than 60% (vs. conventional systems), great partner support
Landmark Heritage Building with Government Offices in New Delhi, India
Background & Challenge
North Block is a part of Rashtrapati Bhawan, the sprawling residential complex of the President of India. North Block houses the key offices of Ministry of Home, Ministry of Finance and the others. Ministry of Home is responsible for internal security of India and it operates 24/7 for 365 days in a year. The building was Inaugurated in 1931.
The building is a heritage building, which is over 85 years old. It has mission critical offices and the access to the building is limited for just few hours. The customer was interested in replacing a legacy system and individual units with energy-saving VRF technology.
LG MULTI V IV is found to be 6-9% more energy efficient compared to other brands' VRF solutions.
On the basis of 11-year power consumption estimates, LG was the winner in the competitive bidding where all the major players participated. Speaking on the project, Mr. Manoj Kumar Pandey, Executive Engineer of CPWD said, “For the past decade, the focus of the government has been on energy efficiency. Due to the building’s unique structure, we needed an uncompromised air conditioning solution. CPWD devised a strategy with eminent experts to use the latest air conditioning systems without compromising on the basis features of the building. It was concluded that VRF will be the most suitable for HVAC solution.” He continued, "We are constrained not just by the heritage status, but also that the building houses VVIPs. Access timing was a major limitation in the execution of the project. LG has definitely burnt midnight oil to get this project completed on time. In day, there was a zero possibility of doing any work at all.”
Power Saving Estimates - LG vs. Other Brands
Comparison on total loading for 1 year, Cooling mode & heating mode measured based on total loading for 3,674 HP considering base unit of 48 HP for 1 year. For 11 years, LG is projected to be INR 13,728,450 more efficient and economical option, compared to other brands.
