IGBC Net Zero Carbon Rating

IGBC Net Zero Carbon Rating

The IGBC Net Zero Carbon rating system is a voluntary and consensus-based programme. The rating system is fundamentally designed to encourage the use of low-embodied carbon materials, optimise the buildings’ performance using passive features and technologies, and use of on-site & off-site renewable energy systems and carbon sequestration measures to reduce or off-set the carbon emissions associated with the buildings and its concerned environment.

The rating system evaluates certain mandatory requirements & credit points using a prescriptive approach and others on a performance-based approach.


Benefits

The IGBC Net Zero Carbon rating system addresses the three pillars of sustainability i.e., Social, Environmental and Economical; thereby, the building and campus projects adopting net zero carbon concepts can have multi-fold tangible and intangible benefits.

  • Carbon emission reduction: Promotes the reduction of greenhouse gas emissions, contributing to India's efforts to combat climate change
  • Resource efficiency: Encourages the efficient use of resources, minimising the environmental impact associated with building construction and operations
  • Energy conservation: Promotes the use of energy-efficient technologies and practices, reducing overall energy consumption in buildings
  • Renewable energy integration: Encourages the integration of renewable energy sources, such as solar power, to meet building energy needs
  • Efficient water use: Encourages the adoption of water-efficient technologies and practices to minimize water consumption in buildings
  • Waste minimisation: Emphasizes the reduction of construction and operations waste through responsible practices.
  • Climate adaptation: Promotes building designs that are resilient to the impacts of climate change, ensuring long-term viability and safety

Scope

The IGBC Net Zero Carbon rating system promotes resource efficiency and encourages use of renewable energy and carbon sequestration measures to offset carbon in Design & Construction phase and Operations phase through the following:

  • The Net Zero Carbon rating system (pilot version) is designed for both new & existing buildings and campuses.
  • Net Zero Carbon buildings and campuses include (but are not limited to) airports, commercial, educational institutions, healthcare, hospitality, residential, transit, etc.
  • Projects in Design & Construction phase are those which are design and/ or in construction or in operations for less than one year.
  • Projects in operations phase are those which are in operations for more than one year.
  • The rating system is applicable for buildings with enclosed and habitable spaces.
  • The rating system is applicable to owner-occupied/ tenant-occupied/ mixed-use permanent buildings and campuses with at least one occupant.
    • Interior fit-out projects are not eligible to apply in the present version
  • The tenant-occupied projects shall include the scope of work as per the scope of developer only and not that of tenants while demonstrating compliance.

Types of Certifications

Projects can apply for IGBC Net Zero certification during Design and Operation phase, and following are the types of certification:

  • Design Certification - For projects in Design and Construction stage.
  • Operations Certification - For projects in Operations stage for at least one year. Such projects should have implemented the measures and also have the recent annual performance data for validation.
  • Provisional Certification - For projects in Operations stage for at least three months. Such projects should have implemented the measures and also have the recent three months performance data for validation.

Certification Levels

The different levels of rating awarded are as below:


Design & Construction phase
Rating Level Compliance Requirement Minimum Points to Comply
Near Net Zero Carbon Achieve embodied carbon of less than or equal to 700 kg CO2e/square meter benchmark (and) offset at least 75% of the total operational carbon 40
Net Zero Carbon Achieve embodied carbon of less than or equal to 700 kg CO2e/square meter benchmark (and) offset at least 90% of the total operational carbon 60
Operation phase
Rating Level Compliance Requirement Minimum Points to Comply
Near Net Zero Carbon Offset at least 75% of the total operational carbon 40
Net Zero Carbon Offset at least 90% of the total operational carbon 60

Validity

The rating awarded for IGBC Net Zero Carbon under Design & Construction phase or Operations phase would be valid for a period of 3 years. The projects certified under Design & Construction phase shall apply for Operations phase certification with the prevailing version. The projects certified under Operations phase shall apply for recertification with the prevailing version.
