Green building certification is a vital component of sustainable construction, promoting environmentally friendly practices in design, construction, and operation. Various certification systems have emerged globally, each with its specific criteria and focus areas. This note provides an overview of several prominent green building certification systems, including the Indian Green Building Council (IGBC), the U.S. Green Building Council (USGBC), GRIHA, WELL, Green Building Certification System (GBCS), and EDGE.
1. Indian Green Building Council (IGBC)
The IGBC, part of the Confederation of Indian Industry (CII), promotes sustainable building practices in India. Its certification programs include IGBC Green Homes, IGBC Green Factory Buildings, and IGBC Green Interiors, among others.
Key Features:
• Focuses on energy efficiency, water conservation, and sustainable materials.
• Provides rating systems tailored to different building types, including residential, commercial, and institutional.
• Encourages local environmental practices and promotes awareness through training and workshops.
2. U.S. Green Building Council (USGBC)
The USGBC is a leader in promoting sustainable building practices in the United States and globally, primarily through its LEED (Leadership in Energy and Environmental Design) certification program.
Key Features:
• LEED ratings are based on a point system covering various sustainability aspects, including energy efficiency, water usage, materials, indoor environmental quality, and innovation.
• Offers different levels of certification (Certified, Silver, Gold, and Platinum) based on the total points earned.
• Widely recognized and respected internationally, influencing building codes and standards.
3. GRIHA (Green Rating for Integrated Habitat Assessment) :
Developed by The Energy and Resources Institute (TERI), GRIHA is India's national rating system for green buildings, emphasizing holistic sustainability across various aspects of building performance.
Key Features:
• Addresses energy efficiency, water management, site development, materials usage, and indoor environmental quality.
• Provides a framework for assessing buildings at different stages, from planning to occupancy.
• Encourages indigenous practices and local materials, fostering regional sustainability.
4. WELL Building Standard:
The WELL Building Standard focuses primarily on human health and wellbeing in the built environment. It complements traditional sustainability metrics by emphasizing occupant comfort and health.
Key Features:
• Assesses aspects such as air quality, water quality, nourishment, light, fitness, and mental wellbeing.
• Certification levels include Silver, Gold, and Platinum, reflecting the degree of commitment to health-oriented design.
• Aims to create healthier indoor environments that enhance productivity and overall wellbeing.
5. Green Building Certification System (GBCS) :
The GBCS, established by the Confederation of Indian Industry (CII), is a holistic approach to green building in India, focusing on various sustainability aspects throughout a building's lifecycle.
Key Features:
• Provides a framework for assessing environmental performance in areas such as site planning, energy, water, materials, and indoor environmental quality.
• Encourages innovation in sustainable design and recognizes the importance of community impact.
• Aims to enhance awareness of green building practices among stakeholders.
6. EDGE (Excellence in Design for Greater Efficiencies) :
EDGE is a green building certification system developed by the International Finance Corporation (IFC), aimed at making green building accessible and affordable.
Key Features:
• Focuses on energy efficiency, water conservation, and resource efficient materials.
• Utilizes a simple online tool to calculate savings in energy and water, helping designers and builders achieve certification quickly.
• Encourages incremental green design, making it suitable for various project scales and types, especially in developing countries.
Conclusion:
Green building certification systems like IGBC, USGBC, GRIHA, WELL, GBCS, and EDGE play a crucial role in promoting sustainable construction practices. Each certification has its unique focus and criteria, addressing various aspects of environmental sustainability and occupant wellbeing. As awareness of environmental issues grows, these certifications will continue to drive the adoption of green building practices, ultimately contributing to a more sustainable future. By achieving certification, stakeholders can not only enhance building performance but also promote healthier and more efficient living and working environments.
