Solar power generation

Power generation through solar photovoltaic system is possible to be used if required

by client and subject to sufficient space availability on roof to install solar panels incoordination with the architect.

The solar panels can generate 220W power per 1.2m2 area. As per the initial reviewsufficient space is not available on roof to install the same. However this can befurther studied in detail in next stage.

Solar power can be used to illuminate the car park lighting/corridor lighting with backup from grid network.

Solar System for lighting:

Overview

The system adopts high-efficiency PV modules and inverters, which can notonly make the most of area of building roofs and generate more electricity butalso collect real-time operating parameters and analyze system status to

realize high-intelligence monitoring by means of data-collectedcommunication station.

System description

The system adopts grid-connected mode and operates in parallel with thegrid.

The PV modules convert solar energy to the DC power, and then the grid-connected inverters convert the DC power to the sine wave AC power whichhas the same frequency and phase with voltage of grid.

The solar energy generated in the sunny day will be used to power loads ofbuilding and thus reduce the intake from the grid.

Grid-connected PV system

If the actual electricity-consumption of loads is not enough to use up the totalpower generated by PV system, the redundant electricity is not allowed toflow into the grid by providing a reverse-power protector. This will ensure toswitch off parts of PV system to avoid the PVs electricity from flowing into thegrid.

See following illustration about the Grid-connected PV system with Reverse-Power Protector:

PV Module

PV modules consist of solar cells made of monocrystalline silicon wafersurrounded by ultra-thin amorphous silicon layer.

27/28



HVAC Systems

1. We would like to introduce Fresh air recovery AHU with desiccant coatedthermal wheel which removes the latent heat in addition to the sensible. Withthis the over all AC cooling load is reduced by at least 15%.

2. The chilled water generation shall be hybrid chillers, if air cooled with CFCfree refrigerant which has much improved kw/TR of cooling in comparisonwith conventional chillers. If the chillers are water cooled, therecommendation would be to go for centrifugal with VFD, which is a latesttechnology introduced only and mastered by York International.

3. We recommend central (district cooling) chilled water generation withindividual building to be with tertiary pumping with VFDs.

4. Option for monitoring the individual tenant actual chilled water consumptionthrough BTU meters and BMS which is more enhanced than charging rent onsq ft rate.

5. We recommend splits or packaged AC units only for isolated and smallfacilities as the kw per TR is high.

6. Depending on the type of area space utilization the space internal coolingcould be by central AHU with VFD (Variable Frequency Drives) instead ofFCU in the ceiling voids. Though there are many advantages like low noise,

no condensation dripping, reduction in power consumption, maintenancepersonal out of working areas, no access panels in ceilings, meets thesustainable design requirements, etc, this depends on the area of eachoccupant and availability of space for AHU.

Plumbing and drainage systems

1. We would like to introduce PEX piping for domestic water distribution fortoilets instead of conventional piping. This will allow for replacement of pipingwithout having to break the tiles.

2. The Urinals and WC flushing can be with duel flushing cisterns, though we

would recommend flush valve system for toilets for auditorium and complexesdue to higher utilization.

3. We recommend providing water metering at each floor levels with centralriser from roof. These meters could be connected to BMS for metering andbilling purpose.

4. We recommend solar water heaters if space permits with the drain backfacility to eliminate bleed of/overflow of hot water during non consumptionperiod.

5. We commend providing separate piping and treatment for Soil and grey

water.

6. We would propose the grey water treatment with the Membrane Bioreactortechnology by which suspended solids can be eliminated up to 99.7% and in



28/28



addition UV filters can be installed to kill all bacterial and reusing treated greywater for WC flushing or cooling tower or irrigation system.
