The European Union’s programme for India This project is funded by The European Union The European Union’s programme for India Clean Energy Cooperation with India (CECI): Legal and policy support to the development and implementation of energy efficiency legislation for the building sector in India (ACE:E2) ECBC Compliant Building Project – Demo Project 18th May 2018 Clean Energy Cooperation with India (CECI): Legal and policy support to the development and implementation of energy efficiency legislation for the building sector in India (ACE:E2) First Regional Workshop to Implement Energy Conservation Building Code (ECBC) in India Session 4- Demonstration Project MEDA, Pune 18th May 2018 Project implemented by EXERGIA S.A. member of SACO Consortium, in collaboration with PwC India This project is funded by The European Union

Purpose of Demo Project To showcase the technical practicalities in achieving ECBC compliance in a building 01 To demonstrate the benefits of ECBC compliance building in terms of energy saving and financial viability of the project 02 To provide evidence and confidence to designers, developers and financial institutions 03

Key stages- Demonstration project The scope of work include the following Identification of buildings Collection of data Data analysis Techno-economic analysis Report preparation and submission The various stages of a building in which the above- mentioned scope of work will be applicable are Stage 1 Design feasibility process Stage 2 Complete design of the building Stage 3 Tendering Procurement of contractor Stage 4* Construction and supervision Stage 5* Commissioning Stage 6* Monitoring and Reporting Study tours

Identification of Demonstration project for ECBC Compliance 1 2 3 New Building a connected load of 100 kW or greater (Contract demand of 120 kVA or greater). having conditioned area of 500 Sqm or more.

Eligible building types under ECBC Educational (schools, colleges, universities, training institutions) Business (Office Buildings) Hospitality (Star hotel, no star hotel, Resort) Assembly (theatres, gathering halls, transport buildings like airports, railway stations, bus stations, and underground and elevated mass rapid transit system) Shopping Complex (shopping malls, stand-alone retails, open gallery malls, super markets, or hyper markets) Health Care

(in-house or consultants) Project team Project Team Architects Civil engineers Electrical engineers ECBC Expert (in-house or consultants)

Data requirement and Roles and responsibilities Responsible person AutoCAD plans, sections and elevations Architect Wall, roof and glass composition Cooling demand, proposed cooling system details (type, capacity, efficiency) HVAC consultant Lighting fixtures, lighting load, comfort details Lighting consultant Service water Plumbing consultant Solar hot water Plumbing and electrical consultant Electricity distribution system Electrical consultant Renewable sources of energy Metering system Energy performance details Energy/Green building consultant

Overall Approach to Demonstrate ECBC compliance Building design Final building loads and consumption HVAC system optimization Wall optimization Envelope optimization Roof optimization Inside temperature optimization Fenestration optimization Optimized Electrical load(kW) Heat load optimization Optimized Cooling load (TR) Daylight optimization Lighting system optimization Artificial lighting Low energy strategies Optimized energy consumption (kWh) Daylight integration Efficient HVAC equipment selection Timespan- 2-6 months
