3. Other Regional and International Green Building Certifications

International Systems

• WELL: Focus on human health and wellbeing, air, water, nourishment, light, fitness, comfort, and mind in buildings. (Certifying Body: WELL Building Institute, IWBI, USA)
• Green Globes: Flexible, web-based assessment for sustainability and building performance. (Certifying Body: Green Building Initiative, USA)
• DGNB: Emphasizes life-cycle analysis and European standards. (Certifying Body: German Sustainable Building Council, Germany)
• CASBEE: Context-specific criteria, including building enclosure, energy, and local environment. (Certifying Body: Japan Sustainable Building Consortium, Japan)

This chunk discusses various international green building certifications that focus on different aspects of sustainability.

1. WELL: This certification emphasizes human health and wellbeing. It considers factors like air quality, water quality, proper nourishment, sufficient light, fitness opportunities, comfort in spaces, and mental wellbeing. This means that in addition to being environmentally friendly, buildings must also support the health of their occupants.
2. Green Globes: This certification offers a flexible, web-based assessment tool that focuses on sustainability and performance metrics of buildings. It allows for varied assessments depending on the type of building and the specific sustainability goals being pursued.
3. DGNB: The German certification emphasizes a life-cycle analysis, which means that it evaluates the environmental impact of a building from its initial design and construction through its operational life and even its eventual demolition.
4. CASBEE: In Japan, this certification tailors its criteria to local environmental conditions, assessing factors like building enclosure (how well a building contains its internal environment), energy efficiency, and integration with the local environment.

Think of these certifications like different schools specializing in various subjects. Just like a school might focus on health sciences, engineering, or the arts, these green building certifications specialize in promoting specific aspects of environmental sustainability and human health. For instance, choosing WELL certification is like choosing a school that specializes in healthy living and wellness, which is particularly relevant for buildings where people spend a lot of their time.

Regional Systems

• GRIHA: India’s national rating system, adapted for climatic and development conditions in India. Focuses on energy and water savings, and socio-economic impact.
• IGBC: Widely adopted in India for a variety of building typologies, closely aligned with LEED but tailored to Indian contexts.
• Green Star: Australia’s national green rating system, rigorously adapted to local environmental priorities.
• Estidama: Pearl Rating System developed in Abu Dhabi, UAE, for sustainable urban development in arid regions.
• MINERGIE: Certification from Switzerland that emphasizes low energy consumption in buildings.

This chunk highlights five regional green building certifications that cater to specific local needs and conditions:

1. GRIHA: This certification is unique to India and is designed considering local climate and socio-economic conditions. It aims to promote energy and water efficiency while also addressing the social impacts of building practices.
2. IGBC: Similar to GRIHA, the Indian Green Building Council certification is tailored to various building types in India while aligning closely with standards set by LEED, making it relevant to Indian constructors and developers.
3. Green Star: This certification focuses on Australia’s environmental priorities and adapts its requirements to fit the local context, ensuring that buildings are sustainable in an Australian setting.
4. Estidama: This certification, which means 'sustainability' in Arabic, promotes sustainable urban developments that are specifically designed for the unique climatic challenges faced in arid regions like Abu Dhabi.
5. MINERGIE: This Swiss certification focuses on energy efficiency, ensuring buildings consume as little energy as possible while still maintaining comfort and usability.

Imagine you are traveling to different countries. In each country, the customs and regulations might differ. Similarly, regional certifications like GRIHA and IGBC are tailored to their local environment, much like how a travel guide would suggest what to wear or eat based on the local culture and climate. For instance, if you go to a hot climate, you'd be advised to dress in light fabrics; similarly, buildings in India must be designed to respond effectively to its specific climatic challenges.

Comparative Table: Key Attributes

This chunk presents a comparative table that summarizes various green building certification systems by their key attributes. The table indicates the region where each certification is recognized, its main focus areas, and how scoring is structured.

• LEED: Recognized globally, it evaluates buildings based on multiple criteria, including energy and indoor environmental quality, with four different levels of certification based on points attained.
• BREEAM: Focused on the UK and Europe, offers customizable certifications with varying grades of performance based on assessments from 'Pass' to 'Outstanding'.
• WELL: Acknowledged worldwide, it highlights health and wellbeing. Its certification levels focus on promoting occupant health while achieving 'Silver', 'Gold', or 'Platinum' status based on performance.
• GRIHA: Exclusive to India, this rating system assesses key local issues such as water and energy management, with scoring from one to five stars.
• Green Star: An Australian system that encourages innovation and emphasizes ecological impacts, using a star rating from 1 to 6.

Think of this table like a report card for different schools that offer varying subjects. Just as a student's performance can be evaluated through letters (A, B, C) or stars (1 star to 5 stars), the certifications offer various levels to assess how environmentally friendly a building is. For example, just as an 'A' would signify excellent performance, a 'Platinum' rating in LEED suggests the building is among the best in environmental sustainability.

Selection Considerations

• Climate and Context: Regional systems may be better aligned with local regulations, construction practices, and environmental challenges.
• Building Type and Function: Some certifications offer specialized tracks for schools, homes, offices, or entire communities.
• Performance Emphasis: Some emphasize operational performance, others design intent or occupant health.
• Market Recognition: LEED, BREEAM, and WELL are highly recognized by global investors and multinationals.

This chunk outlines important factors to consider when selecting a green building certification:

1. Climate and Context: Depending on where a building is located, certain certifications may be more suitable. For instance, a certification designed for arid regions would be more applicable in a hot desert climate than a tropical one.
2. Building Type and Function: Different types of buildings (like schools, homes, or offices) may have unique requirements that one certification might address better than another. It’s important to choose based on the specific needs of the building type.
3. Performance Emphasis: Some certifications prioritize how well a building operates in practice, while others focus on the design intentions or how healthy the occupants feel inside. Understanding the difference is key to selecting the right one.
4. Market Recognition: Certifications like LEED, BREEAM, and WELL have strong recognition in the market, which can enhance attractiveness to investors and clients. Choosing a well-recognized certification can provide additional benefits beyond environmental performance alone.

Selecting a green building certification can be likened to picking the right college for a student based on their interests, location, and reputation. Just as one may choose a school known for science if interested in pursuing a career in medicine, builders must select the certification that aligns best with their local climates, building types, and the recognition that might help in attracting tenants and investors.
