IGBC Net Zero Energy

As part of the project titled "Facilitating the Uptake of Net Zero Energy Buildings in India by Enabling the Development of Policy Mechanisms and Supporting Ecosystem," IGBC conducted a study focused on developing recommendations for a Net Zero Energy Policy Framework, grounded in an economic impact analysis.

This study provides a comprehensive assessment, including a review of the Energy Conservation Building Code (ECBC), the current status of its implementation in selected states, and an evaluation of the policy and regulatory frameworks governing renewable energy (RE)–based power generation. It also includes an analysis of state-level RE and solar policies. Furthermore, the study examines the economic feasibility of rooftop solar installations under both net and gross metering mechanisms, as guided by existing policy and regulatory provisions. The states selected for this economic impact analysis are Andhra Pradesh, Karnataka, Maharashtra, and Rajasthan.

Duration: 2021-2022

To promote the concept of Net Zero Energy Budlings in India and to create an eco-system for zero energy buildings, in early 2022 both CESL (Convergence Energy Service Limited) and IGBC kick-started a joint initiative. The collaboration of CESL and IGBC is supported by JICA (Japan International Corporation Agency). Scope of the initiative is to facilitate conversion of existing buildings into Net Zero Energy which can enable the project to achieve high energy efficiency in operation and can off-set grid energy use by Renewable Sources at least 80%.

Key tasks of the joint initiative: :

1. I. Selection of 5 prominent buildings in NCR Delhi those are willing to invest themselves for enhancement to a Net Zero Energy Building
2. II. Carry out Walk-in-Audit in selected buildings and prepare feasibility report, shortlist 2 buildings those are more suitable for conversion into Net Zero Energy Buildings based on value addition especially in terms of energy efficiency and use of renewable energy
3. III. Conduct detailed Energy Audits of an investment grade detailed project report (IGDPR) for the identified 2 buildings. To cover energy usage pattern of the building and identification of major load centres and their energy consumption, energy & maintenance cost
• Review of baseline energy consumption in lighting, cooling, heating, ventilating and water pumping areas and calculate Specific Energy Consumption (SEC)
• Study of electrical distribution system from supply side including transformer loading and reactive power system
• Develop schematic for installation of energy efficient appliances indicating the (estimated) baseline energy consumption, post-implementation deemed energy savings, cost savings, and investments required
• Study of spaces to identify renewable energy potential zones for installation of Roof-top and on-site solar systems
4. IV. Designing energy conservation and solar power generation & control system and Support to CESL in Implementation
5. V. Develop methodology to measure & verify the achievement of Net Zero with suitable documentation
6. VI. Developing reports to calculate baseline, plan implementation process and post the implementation M&V (Measurement & Verification) shall be carried out to validate savings/performance.
