  • All Air Handling Units are equipped with high efficiency MERV14 filters and Operation Theaters with HAPA filters

Avasa Hotels, Hyderabad

Chillers installed with Variable Frequency Drives optimize energy consumption leading to annual
savings of 2 lakh units. Variable Frequency Drives on Kitchen Exhausts and Fresh Air Blowers coupled with
demand based control system reduce energy footprint by 10,000 units per month.

Sustainability initiatives  

  • 50% less energy consumption for lighting systems with the use of LED lighting
  • Rs.3 lakhs per annum saved by installation of Heat Recovery Wheels
  • Rs.7-8 lakhs per annum saved due to the installation of Heat Pumps instead of conventional boilers
  • 250 KL capacity Sewage Treatment Plant catering to tertiary applications

ITC Maurya, New Delhi

The chillers equipped with a tube cleaning system enable efficient heat transfer. Variable Frequency Drives installed on Chillers, Pumps, Air Handling Units, Cooling Towers and Water Pumps leading to an energy saving of 8-12%. Efficiency of heat transfer is accentuated with the use of nano-fluid embedded chilled water.

Sustainability initiatives  

  • 1st hotel globally to install solar concentrators for hot water and steam requirements
  • 100% of the rainwater harvested coupled with a Sewage Treatment Plant based on membrane bioreactor technology

Exemplar Edifices : Blueprint for a sustainable future

Buildings in India consume close to 40% of the nation’s total energy today. We spend more than 80% of our life indoors in buildings. Thus, energy conservation in buildings becomes a cornerstone of any sustainable development strategy and efforts. Further, more than 40% of the energy consumed in a building is by the building HVAC system.  Danfoss & CEPT Research and Development Foundation

(CRDF) have partnered to bring together this compendium will be a source of inspiration, and provide guiding principles and valuable insights to stakeholders in the industry in making their future projects greener and more energy efficient
