Best Practices: Energy Management

In Energy management we follow certain practices that help us in reducing our electricity bills without affecting the quality of life. We have benefitted from these practices; our results show maximum 30% reduction in our electricity bills. These practices can be further improved upon.

We at Paharpur Business Centre follow these best practices in energy management

  • Instead of GLS lamps, we use PL lights, which are plug in CFL lamps, they use compact fluorescent (CFL) technology meaning they are efficient and less costly to replace.
  • All fluorescent lights in our office are Philips trulite which are BEE 5 star rated with electronic ballast.
  • Motion sensors are used to switch off lights in unoccupied common areas.
  • All our displays are energy efficient LCDs/Plasma to save on energy.
  • Energy consumption is monitored and analyzed on daily basis.
  • Green mesh & heat reflective film has been put on the south wesh side of the building to block the direct sun heat into the building.
  • High albedo paint has been put on the building envelope to reduce the indirect heat gain into the building.
  • The heat gain into the building from the rooftop is minimum because of green house.
  • Use of  five star rated equipments especially air conditioners.
  • High Efficiency Super Diesel is used for all DG sets to reduce pollution.
  • Diesel is centrifuged to clean it before use in the Generators.
  • Energy consumption is monitored and analyzed on daily basis on a BAS system
  • Green mesh & heat reflective film is put on the south west side windows of the building to block the direct sun heat into the building.
  • High albedo paint has been put on the building envelope to reduce the indirect heat gain into the building.
  • The heat gain into the building from the rooftop is minimum because of green house that has been created on the roof.

Energy Saving Features of our HVAC System

  • Chiller has a COP of 6.15; it’s an efficient 212 TR water cooled screw chiller from Trane.
  • Two way valve regulate the chilled water inlet into the AHU coil as per the heat load.
  • CO2 sensors have been put to regulate the fresh air inlet inside the air conditioned space. Its demand controlled ventilation.
  • New Pumps and all AHU motors are VFD controlled.
  • UVC light have been installed on the AHU cooling coils to keep the air & coil clean of indoor air contaminants.
  • The new system has VAV in air circuits to regulate the air supply as per heat load.
  • New Double skin AHU help reduce the leakage & noise.
  • Heat Recovery wheel unit ensures that incoming fresh air is precooled before it is let in into the system
  • Complete system is managed centrally through BMS

Water Management at Paharpur Business Centre

We measure our water consumption on a daily basis – water meters are installed at all points of consumption at Paharpur Business Centre.

At Paharpur Business Centre we have installed all water efficient fixtures i.e. waterless urinals, sensor taps, dual flush cistern based water closets.

We use drip irrigation for watering the plants.

Reject water from the RO plant is used to water the indoor plants.

As part of our 4R policy – Reduce, Re-use, Re-cycle & Re-charge – we also harvest water and recharge it into the ground.

Dishwasher is used to clean all the dishes in our cafeteria and the first rinse water that is without the detergents is re-used by diverting it to our vermi-compost pit.

Waste Management

Waste Management practices at Paharpur Business Centre

Waste is segregated at source at Paharpur Business Centre – we have separate bins for plastics, food, paper, tin, foil, glass, food.

We sell all paper, Plastic & Glass bottles; our business cards are made from recycled paper.

Wet waste is diverted to our vermi-compost pit where it gets converted into organic manure rich in micro nutrients and this is then used in all our indoor plants as manure.

E-waste generated by us is not thrown but we sell them to vendors who either recycle it or use the spare parts for further repair and use.
