PROJECT BREIF

M/s Nobility Estates Pvt. Ltd. has Proposed Group Housing Project (ATS Le Grandiose), At Plot

No. – SC-01/C-A1, Sports City, Sector – 150, Noida, Uttar Pradesh, having Plot Area 80937.130

sq. m. and built up area 316555.967 Sqm. ATS Le Grandiose is with 1172 dwelling units.

Considering the nature of activities to be conducted and the various aspects of the project to

be developed, our efforts in the approach for the planning of various systems, shall include

the following considerations:

In the operational phase, appropriate energy conservation measures and management plan will be adopted in order to minimize the consumptions of non-renewable fuel.

CFL/LED will be used in place of incandescent lamps in office, common areas and parking.

Percentage saving in energy consumption due to use of CFL/LED will be 15 -20 %. Lighting and switching of common area shall be designed keeping in mind day light

integration.

Roof insulation shall be planned to conserve energy. D.G. sets would be provided with auto cut and auto start mechanism. The water supply pumping system shall be provided with variable speed drive to

conserve energy at part load.

Glass opening will be provided with-in the ECBC limit of 40 %. Building will have appropriate design to shut out excess heat and gain loss.

ECBC COMPLIANCE (Whole Building Performance Approach)

1.0 Introduction The purpose of this report is to assess the compliance of the proposed design of the building

and building systems in line with the Energy Conservation Building Code (ECBC).

A building shall be called ECBC compliant by complying with the mandatory provisions (§4.2-

Envelope, §5.2-HVAC, §6.2- SHW, §7.2 - Lighting, and §8.2 – Power) and either of the

following:

(a) Prescriptive Method (§4.3, §5.3, §7.3) (b) Whole Building Performance Method (Appendix B §10)

Approach of Option B above is being followed to assess compliance for this project.

Specialized building performance modelling software (eQUEST v3.63b) provided a platform for

the energy modelling process. The proposed building geometry was translated into eQUEST

v3.63b to create a 3-dimesional model, other modelling inputs into eQUEST v3.63b included;

lighting, equipment & occupancy gains, operating profiles, plant efficiencies, thermal performance of constructions

To show compliance through Option B, the annual energy consumption of the proposed

building, as estimated by the modeling software, shall be less than the annual energy

consumption of the ECBC compliant base building, as estimated by the same modeling

software

2.0 Building & Site Information The site included three types of apartments, namely Type A, B and C. There are 6 towers of

Type A, 6 towers of Type B and 8 towers of Type C for a total of 20 towers. The site is in Noida

which comes under composite climate zone as classified by ECBC.

3.0 Energy Modelling Overview The “Proposed” energy model was defined and the proposed annual energy use calculated.

Shell multiplier was used for all floors as they were typical in nature.

The energy modelling undertaken included the use of both thermal modelling software

(eQUEST v3.63b) and manual calculations. eQUEST v3.63b thermal modelling software

simulated required plant sizes and annual energy use of the cooling systems for the proposed

energy model. For simplicity, the 2 levels of basement were not modeled.

3.1 Building Geometry The geometry of the proposed building was input in eQUEST v3.63b to create the 3-

dimensional computer model shown in Figure 1

Piping insulation would comply with 5.2.4 ECBC. The

entire hot water system including the storage tanks,

pipelines would be insulated conforming to the relevant IS

standards on materials and applications.

4 Heat Traps

(6.2.5)

Vertical pipe risers serving storage water heaters and

storage tanks not having integral heat traps and serving a

non-recirculating system would have heat traps on both

the inlet and outlet piping as close as practical to the

storage tank.

iv) Lighting


1 Lighting

Control (7.2.1)

Automatic Lighting Shutoff

Interior lighting systems in buildings lobby would be

equipped with an automatic control device. Within these

buildings, all school classrooms, and all lobbies would be

equipped with occupancy sensors.

Space Control

Each space enclosed by ceiling-height partitions would

have at least one control device to independently control

the general lighting within the space. Each control device

would be activated either manually by an occupant or

automatically by sensing an occupant.

Exterior Lighting Control

Lighting for all exterior applications would be controlled

by astronomical time switch that is capable of

automatically turning off the exterior lighting when

daylight is available or the lighting is not required.

2 Exit Signs

(7.2.2)

Internally-illuminated exit signs would not exceed 5W per

face.

3 Exterior

Building

Grounds

Lighting (7.2.3)

Lighting for exterior building grounds luminaires which

operate at greater than 100W would contain lamps having

a minimum efficacy of 60 lm/W unless the luminaire is

controlled by a motion sensor.

4 Lighting Power

Densities (LPD)

20% reduction in ECBC prescribed values with use of LED

higher efficacy LED lighting fixtures.

v) Electric Power


1 Transformers

(8.2.1)

Maximum Allowable Power Transformer Losses

Power transformers of the proper ratings and design

must be selected to satisfy the minimum acceptable

efficiency at 50% and full load rating. In addition, the

transformer must be selected such that it minimizes the

total of its initial cost in addition to the present value of

the cost of its total lost energy while serving its

estimated loads during its respective life span.

2 Energy Efficient

Motors (8.2.2)

Motors would comply with the following:

(a) All permanently wired poly phase motors of 0.375 kW or more serving the building and expected to operate more than 1,500 hours per year and all permanently wired poly phase motors of 50kW or more serving the building and expected to operate more than 500 hours per year would have a minimum acceptable nominal full load motor efficiency not less than IS 12615 for energy efficient motors.

(b) Motors of horsepower differing from those listed in the table would have efficiency greater than that of the next listed kW motor

(c) Motor horsepower ratings would not exceed 20% of the calculated maximum load being served

(d) Motor nameplates would list the nominal full-load motor efficiencies and the full-load power factor

(e) Motor users should insist on proper rewinding practices for any rewound motors. If the proper rewinding practices cannot be assured, the damaged motor should be replaced with a new, efficient one rather than suffer the significant efficiency penalty associated with typical rewind practices

(f) Certificates would be obtained and kept on record indicating the motor efficiency. Whenever a motor is rewound, appropriate measures would be taken so that the core characteristics of the motor is not lost due to thermal and mechanical stress during removal of damaged parts. After rewinding, a new efficiency test would be performed and a similar record would be maintained

3 Power Factor Correction (8.2.3)

All electricity supplies exceeding 100 A, 3 phases would maintain their power factor between 0.95 lag and unity at the point of connection.

4 Check-Metering

and Monitoring

(8.2.4)

(a) Services exceeding 1000 kVA would have permanently installed electrical metering to record demand (kVA), energy (kWh), and total power factor. The metering would also display current (in each phase and the neutral), voltage (between phases and between each phase and neutral), and total harmonic distortion (THD) as a percentage of total current

(b) Services not exceeding 1000 kVA but over 65 kVA would have permanently installed electric metering to record demand (kW), energy (kWh), and total power factor (or kVARh)

Distribution

System Losses

(8.2.5)

The power cabling would be adequately sized as to maintain the distribution losses not to exceed 1% of the total power usage. Record of design calculation for the losses would be maintained.
