1 Indo-Swiss Building Energy Efficiency Project

2 Indo-Swiss Building Energy Efficiency Project The Indo-Swiss Building Energy Efficiency Project (BEEP) is a bilateral cooperation project between the Ministry of Power (MoP), Government of India and the Federal Department of Foreign Affairs (FDFA) of the Swiss Confederation. The Bureau of Energy Efficiency (BEE) is the implementing agency on behalf of the MoP while the Swiss Agency for Development and Cooperation (SDC) is the agency in charge on behalf of the FDFA. Project Objective The overall objective of the project is to reduce energy consumption in new buildings through energy efficient design, construction, innovative technologies and capacity building, and to disseminate best practices. The project contributes to strengthening and broadening the Bureau of Energy Efficiency s (BEE) building energy conservation programme.ect S 1.

3 1. DESIGN Integrated Design Charrettes In order to design a high energy-performance thermally comfortable building an Integrated Design Process is required. All the factors that affect energy performance of the building must be considered; and the architect, engineers and other stakeholders must start working together from the early design stage. THE BEEP INTEGRATED DESIGN PROCESS CHARRETTE is an interactive workshop, held over 4 days, which brings together the building design team and senior BEEP experts to develop the energy concept of the building together during the early phase of design of a building. Early intervention in the building design process allows to tap the largest energy saving potential. INTEGRATED DESIGN CHARRETTE Client Architect Engineers Green Building Consultant PLANNING (6 WEEKS) CONDUCTING ( 4 DAYS) FOLLOW-UP (6 MONTHS) CHARRETTE PREPARATION Getting acquainted with the project team and briefing about the BEEP charrette and its objectives Project data collection Pre charrette analysis of the building project to set the baseline energy performance / thermal performance 4-DAY CHARRETTE DAY 1 Develop a common understanding of the project Set the energy goals List possible solutions to achieve those energy goals BEEP team analyses the energy performance and cost implications of the proposed design cases DAY 2 Group work in architectural and engineering teams for the application of different energy efficiency solutions Integration of shortlisted strategies into proposed design cases DAY 3 DAY 4 Decision on the energy efficiency solutions in the proposed design cases CHARRETTE FOLLOW-UP Charrette report containing the analysis and main recommendations Regular interaction Technical support after the charrette, related to the implementation of the agreed energy efficiency solutions

5 1. DESIGN Design Competition for External Movable Shading Systems Windows / glazed areas of buildings are one of the largest contributors to solar heat gain into the building. Shading them is the easiest, most practical and cost effective solution to making a building thermally comfortable and consequently energy efficient. Movable shading systems have the advantage of adjusting as per the sun s position, specially on the east and west faces of the building. SHGC > 40% SHGC > 40% Inside Outside Inside Outside Internal blinds External movable shading BEEP DESIGN COMPETITION FOR EXTERNAL MOVABLE SHADING SYSTEMS September 2014 Design Competition Launched March 2015 STAGE 1: DESIGN STAGE Evaluating creativity & innovation The Solar Heat Gain Coefficient (SHGC) of all 5 prototypes in closed position vary from 0.06 to This means that in closed position, they are able to block 75-94% the heat entering through the window. July 2015 STAGE 2: MOCK-UP STAGE Evaluating operability & effectiveness 3 designs (residential) selected 2 designs (commercial) selected April 2016 STAGE 3: PROTOTYPE TESTING Testing of the final 5 designs at CARBSE, CEPT University

6 2. TECHNOLOGY BEEP has worked in the following areas: Building Insulation Material Testing Insulation helps reduce heat transfer. So, in hot climates, insulation on roofs and walls reduces the transfer of the heat from outside to the inside spaces. In cold climates, insulation prevents heat transfer from the warmer inside spaces to outside. a) Development of the physical infrastructure and human competencies in selected Indian laboratories for testing of building insulation materials in India. b) Providing assistance to BEE in development of a label for building insulation materials. c) Making available training material package on building insulation.
