ACREX Hall of Fame

This showcase mankind’s efforts to do good for the nature and its’ children - to enable sustainable living, to reduce pollution, to revive damages and to restore environment friendly practices for the generations to come. An inspiration for every architect, builder, innovator - to go beyond established norms.

The design incorporates open work spaces close to the facade bringing
in natural light, while the thermal transmittance and solar control
building skin reduces heat ingress.

Spacious collaborative and recreational zones are integral parts of the campus to encourage employee health and wellness.

Thoughtfully designed terraces further add to the aesthetics of the building, whilst further reducing the heat ingress.

The IGBC Platinum-rated campus boasts lush green lawns, a widespread
tree cover, and a one-of-its-kind Geothermal HVAC System
with zero water discharge.

The buildings sport white rooftops that reduce heat island effect, with insulation above & under deck for the entire campus decrease load on air conditioning systems.

ISB Mohali has bagged several awards such as the Smartest Educational Building in India, the Most Energy Efficient Educational building in Punjab, and the Best Green Campus Award.

Sustainability initiatives 

• VFDs installed on Chillers, Secondary Pumps, Cooling Towers, and Air Handling Units
• Geothermal HVAC system with Zero Ozone Depletion Potential Refrigerant ensures zero water discharges
• 40% of the building is daylit and
  90% LED light fixtures with automated lighting control
• 100% Solar Photovoltaic
  for basement lighting
• Highly efficient Cross-wave Modular Rainwater Harvesting System
• Use of PIBCV on AHU for ensuring thermal comfort
• 100% Organic Waste converted
  on campus used for horticulture

ITC Kohenur’s architecture is inspired by nature. Its unique building structure captures maximum sunlight. The building profile is smoothened to merge with nature and site landscape. It is folded within setback and further tapered to reduce solar gain. Insulated walls and roofs with high thermal mass, thereby reducing energy needs. The design is not just sustainable but is future-proof as well. Some of its bays, featuring sky gardens, can be turned into rooms in the future, thereby not interfering with the original architecture. Moreover, ITC Kohenur uses 55% locally procured regional materials, thereby further reducing carbon footprint caused by transportation and other sourcing factors.

Sustainable initiatives 

• Magnetic Bearing Centrifugal Chillers
  with COP of 6.4
• Variable Frequency Drives &
• Pressure Independent
  Balancing Control Valves on Air Handling Units for
  continued thermal comfort in varying occupancy levels
• 85% of regularly occupied areas are daylit and
  33% reduction in lighting energy use compared to code
• Shuniya Aqua - In-house filtered drinking water
  that has traveled ‘Zero’ km
• 77% reduction in water demand by using onsite Sewage Treatment Plant and low flow fixtures
• Enhanced Indoor Air Quality with 30% more fresh air than required norms
• Centralised collection for wet & dry waste with on-site Organic Waste Convertor

Vestas Ahmedabad boasts of an innovative building concept has a
4.5 m multi-level service alley with a separate utility corridor to isolate
production and services areas. This makes the Ahmedabad facility
more aesthetic, the most energy efficient, and fastest built facility by Vestas across the world. The idea has been adopted for other Vestas projects across the globe.
Moreover, it has a fully insulated building envelope made with mineral wool service panels. The facility employs centrifugal chillers with auto tube cleaning system, CTI certified Cooling Towers, and Air Handling Units fitted with MERV 8 filters and jet nozzles to reduce the duct temperature rise.

Sustainability initiatives  

• Automatic Tube Cleaning System in Chillers
  and CTI-certified Cooling Towers
• Air Quality Monitoring System for PM 2.5, PM 10, NOx,
  SOx, Co2 and VOCs with regular audit
• Variable Frequency Drives in Centrifugal Chillers
  and Secondary Pumps
• Around 10 kl of low temperature condensate water for reuse in Cooling Tower
• Around 28 lakh per annum saved by installation
  of Air to Air Cross Flow Plate Type Heat Exchanger
• 100% Rainwater Harvesting done with a 50 KLD
  Sewage Treatment Plant based on MBBR Technology

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
