Building Envelope

Roof Insulation and Roof Design • Roof sheeting area covered with a high quality

insulation material enable s in achieving a much lower U-value, than baseline

• The roof of the building has stylized incisions to allow daylight, angled to protect the interior from direct sunlight. The use of natural light reduces the dependency on artificial light during daytime thereby air-conditioning load.

Glass wall area • High performance double glazed panels coated with

reflective low e-glass panes enable in achieving a lower U-value.

• High quality glass with lower shading coefficient and

high visible light transmittance enhances available daylight in the space and reduces heat gain.

Energy Efficient Chillers

Chillers

• High efficiency chillers with double compressors are used to optimize load based on hourly profile of heat loads carried for the entire year.

• Temperature differential across Chillers is 40% higher than normal industry standards, thereby reducing the water pumping energy requirement apart from reduction in pipe sizes.

• Secondary chilled water pumping system is installed in combination to Pressure Independent Dynamic Valves (PIDV) to optimize use of energy in fluid operations.

Specific power consumption (kW/TR) 0.740 0.665

Variable Frequency Drives

Secondary Pumps • Chilled water is pumped with a primary and

secondary pumping arrangement. While the primary loop pump circulates chilled water through the chillers and the secondary pumps circulate chilled water to the AHUs.

• VFDs in the pumps of secondary chilled water loop accommodate the variations in the chilled water demand as per the load thus resulting in electricity saving as compared to conventional case

Cooling Tower Fans • Cooling towers of 8 * 3000 TR capacities are used

to provide the cooling water in the condensers of the refrigeration cycle.

• VFD’s installed on the cooling tower fans accommodate the variation of the based on the condensing circuit of HVAC system.

• Each cooling tower has two fans hence 14 fans will always be running and 2 are in stand by mode at any given point of time load

Energy savings: 2,727 MWh

Energy Savings: 1,317 MWh

10

Improved Insulation

• Insulation in the supply air, return air ducts and chilled water pipes are designed and installed extensively to minimize energy consumption.

• Heat gain or heat transfer is reduced by increasing the thickness of fiber glass used as insulating material which improves the thermal properties in supply air duct, return air duct and chilled water piping circuit.

• Effective under deck insulation is applied to reduce heat load.

Energy Efficient AHUs

Air Handling Units (AHUs) • AHU’s supplied for the project comply to EUROVENT Standards viz EN-1886. Low leakage

rates & low thermal conductivity results in less losses & in turn less energy consumption.

• ARI certified coils have been used for more efficient and predictable cooling performance.

• Separate AHUs are used for façade and internal areas for more efficient temperature and reduced reheating during winter.

• Variable Frequency Drives (VFD) are equipped with all AHUs to allow running at minimum required RPM inline with filter pressure drops which results in energy saving.

• Variable Air Volume (VAV) box is provided wherever AHU is serving multiple zones. VAV is used in air distribution system for better space temperature control and modulated air supply for energy efficient design system.

• Free cooling concept implemented to save energy in the event when outside thermal conditions are conducive.

• Air Purification system (APS) provided for volatile organic compounds reduction minimizes the fresh air requirement and results in energy saving.

• Usage of HFC refrigerants for reduced Ozone Depletion Potential (ODP) and Global Warming

Potential (GDP).

12

Tempered Cooling System

Conventional Ventilation System

• Energy Intensive – Require High capacity exhaust and supply fans with evaporative cooling system to maintain the human comfort working condition (15 air changes, 350c)

• Humidity High, water consumption high.

Tempered Cooling system • Usage of tempered cooling concept in design and equipment selection instead of

ventilation units for non public areas / equipment rooms minimizes the space requirement for the ventilation equipment

• Chilled water circulation through AHUs /FCUs to maintain the human comfort working condition.

• Humidity low, low water consumption.

Estimated Energy savings: 9,567 MWh

13

Sensors

Lighting levels & electrical consumption is monitored and controlled inside the building using

sensors.

• Occupancy Sensors - The occupancy sensors monitors & control the switching ON/OFF of lights according to the occupancy of areas.

• Light level sensors - The device measures the ambient light level and communicate messages on the bus system to regulate light level within defined limits.

• Multi Function Meters – Used for more efficient energy usage monitoring and load management.

• Photo sensors - In order to balance artificial and natural light levels inside the building, photo sensors are used for day light tracking.

• Motion sensors – These devices are designed to automatically detect movement and control lighting in response.

• CO2 sensors – Used for enhancing Indoor Air Quality, HVAC CMS can also help to ensure comfort and health of a building’s occupants by automatically monitoring the amount of fresh air that enters the space and adjust fresh air through CO2 sensors.

14

Radar Sensors , VVVF and Gearless Machines

Radar Sensors

• All Escalators and Travellators are equipped with sensors at the ends to enable the equipment to achieve a slow speed of about 0.2 m/s when there are no passengers detected.

• These sensors in turn enable the equipment to go to sleep mode 3 mins after slow speed is activated.

VVVF (Variable Voltage Variable Frequency)Drives

• All Lifts, Escalators and Travellators are equipped

with VVVF drives which reduce the inrush starting current of the machine by 50% each time they starts.

Gearless Machines • 54 out of 71 Lifts at T3 use Permanent Magnet

Gearless Machines, with improved power factor (>.8) to save energy

Estimated Energy Savings: 1,514 MWh

15

High Quality Reflectors and CMS

High Quality Reflectors

• Low wattage Halogen lamps with high quality reflectors in airfield ground lighting helps saves energy while giving more brightness.

CMS • CMS-RVR Interface to regulate the brightness of

airfield lights depending on visibility.

• CMS in airfield ground lighting helps to remotely switch off lights when they are not required hence saving considerable amount of energy.

• The pit & duct system adopted in T3 avoids use of lengthier cables, thereby reducing voltage drops and hence energy consumption.

16

Electro motors and Photoelectric Cells

Power Effective Electro motors

• Latest generation of power effective electro motors are used to drive the conveying plant which effectively saves the power consumed

Photoelectric Cells • Power safe mode based on Photoelectric cells

render conveyors and carousels into sleep mode if no baggage is detected for a certain time.

• This is available for each single conveyor and baggage racetrack.

17

Variable Frequency Drives

• The VFD drives propel conveyors with high efficiency and saves electric power.

• Use of solid state variable frequency (VFD) controlled AC motors helps save energy in

passenger boarding bridges
