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
