Point wise reply Point 1: Submit revised water balance for the Project There is no change in water and wastewater generation. However, water balance enclosed as Annexure-I. Point 2: A detailed report on compliance to ECBC-2017 NORMS A detailed report on compliance to ECBC and Energy Conservation Report is attached as Annexure-II Point 3: Submit details of parking plan along with no. of ECS proposed Parking Details - The total parking area required is Sqm & proposed parking Sqm is provided in basement. Total number of car parking is 447 ( ) ECS. The details of the Parking is provided in the following table. Calculation of Parking Requirement Tower 1 Tower 2 Tower 3 Tower 4 Tower 5 (Sqm) (Sqm) (Sqm) (Sqm) (Sqm) Stilt Non-F.A.R Basement Area Total Covered Parking Total No. of Car Parking (Basement + Stilt) ( ) = 447 ECS Required Parking Area (25% of Total F.A.R) Area = Sq.m. Total Covered Parking area Achieved = Sq.m. Point 4: Status of application to CGWA for use of ground water The proposed project is at zero stage hence no construction activity has been started. Since the ground water is required during the operational phase of the project to meet day to day of population. Therefore we will get the required NOC from CGWA before operational phase of the project. We will submit the the Acknowledgement copy of the CGWA application to the MoEF&CC.

5 Mohammadpur Korji, P.S.- Phulwarisharif, District- Patna, Bihar by M/s Balprada Built Pvt. Ltd. Annexure-II ECBC-2017 Compliance & Energy Conservation Report Point 2: A detailed report on compliance to ECBC-2017 NORMS Energy Conservation Building Code (ECBC) Incorporation of energy efficiency provisions at the design stage of the new buildings is critical and so will be made mandatory by Ministry of Power by 2017 for all new buildings. Better to be proactive than keeping in view the Energy Conservation Act 2001 (EC Act), Bureau of Energy Efficiency (BEE) with technical support from USAID under its Energy Conservation and Commercialization (ECO) Project, has developed Energy Conservation Building Codes (ECBC). ECBC, considering five climatic zones in India, sets the minimum energy performance standards for large housing project that have a connected load of 500 kw or greater or a contract demand of 600 kva or more, having conditioned area of 1000 sq. m. or more. Electricity consumption in ECBC compliant buildings can be brought down to kwh per sq. m., showing energy saving potential of % depending on the hours of building use during the day, climatic conditions, etc. Ministry of Power, Government of India launched ECBC 2017 on June 2017 for its implementation in buildings on voluntary basis all over India, with a view to make this mandatory in the next couple of years depending upon the experience gained during the voluntary period. ECBC encourages energy efficiency for all building components and systems such as building envelope, lighting, heating ventilation and air conditioning (HVAC), service water heating, and electric power and motors within the building facilities, while enhancing the thermal and visual comforts and productivity of the occupants. ECBC mandates/prescribes U-factor and R values of insulation assembly for five climatic zones in India, Solar Heat Gain Coefficients and Visible Light Transmission levels for fenestration, energy efficiency levels of air conditioning systems, and number of other parameters for ECBC compliance in commercial buildings. In this context, good understanding of ECBC features and application of several developed products and technologies could play an important role in improving energy efficiency in the buildings, leading to energy cost savings for the building owners/user.

6 Mohammadpur Korji, P.S.- Phulwarisharif, District- Patna, Bihar by M/s Balprada Built Pvt. Ltd. While operating and using a building energy is used in following ways:- a) Light and Fans etc. b) Air-conditioning and ventilation c) Transformers d) Electric Motors for Pump sets, water supply and lifts The details of Energy Conservative measures adopted in Harinagar Group Housing project as per ECBC 2017 are given below:- a) Light and fans:- Use of Energy efficient lightings:- All the light features are proposed as per Building area wise, strictly following the guidelines of ECBC 2017 as mentioned in Table to achieve required LPD (W/m 2 ). In most of the areas, LED Light fixtures are proposed. In other areas T5 Tube Light with electronic ballast in proposed. Only BEE rating fans are proposed for all buildings. Automatic light control will be in Corridor, the lighting circuits are controlled through occupancy sensors so that unnecessary loss of power can be avoided. Automation in switching- optional Provision has been made in IBMS system for Dimming/Switch ON and OFF of Lighting circuits in areas larger than 2500 sqm, External lighting as per schedule programming through lighting controls, photo electric sensors, Timers. b) Transformers: The Power transformers of proper rating and design have been proposed with acceptable efficiency and full load rating Maximum allowable loss has been proposed as per the mandatory of ECBC Table ie., 1%. All transformers should be equipped with metering class CT/PT for measurement of losses c) Energy effient Motors: All the prime movers for lifts, pumps and other appliances of higher capacities have been proposed as per IS as amended upto date. All the motors have been designed as per ECBC clause so that power rating shall not exceed 200% of maximum load. All pumps control will be through variable frequency drive. d) Metering: Services not exceeding 65KVA shall have permanently installed Energy Meters

Ltd. a) Pipes and Ducting:- The piping and ducting for Heating system is designed for operation at 60 c or greater as per ECBC 2017 clause 5.8. Insulations exposed to weather shall be with aluminium sheet cladding. Duct insulation work shall be strictly followed as per table of ECBC b) Proposed Architectural features for Energy saving as per ECBC are: The building orientation for AC areas is as per geographical location of city to reduce heat gain.
