Green building, also known as sustainable or eco-friendly building, refers to the practice of designing, constructing, and operating buildings in an environmentally responsible and resource-efficient manner. It involves incorporating various strategies and technologies to minimize the negative impacts of buildings on the environment and human health while maximizing their positive effects.

Key principles and features of green building include:

1. Energy Efficiency: Green buildings are designed to minimize energy consumption by incorporating features such as efficient insulation, energy-efficient appliances and lighting, passive solar design, and renewable energy systems like solar panels or wind turbines.
2. Water Efficiency: Water-saving measures are implemented to reduce water consumption, such as using low-flow fixtures, rainwater harvesting systems, graywater recycling, and efficient irrigation techniques.
3. Sustainable Materials: Green buildings use environmentally friendly and sustainable materials, such as recycled content, rapidly renewable resources, and materials with low environmental impact. This includes using sustainable wood, recycled steel, low VOC (Volatile Organic Compound) paints, and non-toxic materials.
4. Indoor Environmental Quality: Special attention is given to creating a healthy indoor environment, with good air quality, adequate ventilation, and abundant natural light. This involves proper ventilation systems, low-emission materials, and the use of natural daylight to reduce the reliance on artificial lighting.
5. Site Selection and Land Use: Consideration is given to the building’s location and impact on the surrounding environment. Green buildings often prioritize infill development to reduce urban sprawl, promote public transportation access, and preserve open spaces. Additionally, strategies like green roofs, permeable surfaces, and landscaping with native plants are employed to mitigate the impact on natural systems.
6. Waste Reduction and Recycling: Efforts are made to minimize construction waste and promote recycling during the building process. Design features such as on-site recycling centers and the use of recycled materials help reduce waste generation and encourage a circular economy approach.
7. Life Cycle Assessment: Green building takes into account the entire life cycle of a building, including its design, construction, operation, and eventual demolition. This holistic approach ensures that environmental impacts are considered at every stage, from material sourcing to long-term energy and water usage.

Green building practices and certifications, and Green Star, provide frameworks and guidelines for achieving sustainable building goals. These initiatives promote a more sustainable and resilient built environment, addressing climate change, resource depletion, and environmental degradation.

hen it required Green building ?

Green building is required or encouraged in various contexts, depending on the specific regulations and policies of different countries, states, and municipalities. Here are some common scenarios where green building practices may be required or encouraged:

1. Building Codes and Regulations: Many jurisdictions have adopted building codes and regulations that incorporate energy efficiency and environmental standards. These codes may mandate certain green building practices or require compliance with specific sustainability standards during the construction or renovation of buildings.
2. Government Initiatives and Incentives: Governments at different levels often promote green building through various initiatives and incentives. This can include grants, tax credits, or rebates for implementing energy-efficient technologies, using renewable energy systems, or achieving specific green building certifications.
3. Certification Programs: Green building certification programs, BREEAM (Building Research Establishment Environmental Assessment Method), and Green Star, are voluntary programs that provide guidelines and standards for sustainable building practices. While certification is not mandatory, it is increasingly sought after by developers, building owners, and tenants as a mark of environmental responsibility and efficiency.
4. Corporate and Institutional Policies: Many corporations, institutions, and organizations have adopted their own sustainability policies that prioritize green building practices. They may require new buildings or renovations to meet specific sustainability criteria or pursue green building certifications.
5. Environmental Targets and Climate Change Mitigation: Governments and organizations committed to addressing climate change and reducing greenhouse gas emissions often encourage or mandate green building practices. Sustainable buildings play a crucial role in reducing energy consumption, minimizing carbon emissions, and mitigating the environmental impact of the built environment.

It’s important to note that the specific requirements and regulations regarding green building vary across different regions and can change over time. Therefore, it’s essential to consult local building authorities, codes, and certification programs to determine the specific requirements applicable to a particular project or location.

Who is required green building ?

Green building practices are relevant to various stakeholders involved in the construction, operation, and maintenance of buildings. Here are some of the key entities that are typically involved in or required to consider green building:

1. Government Agencies and Regulatory Bodies: Government agencies at different levels, such as local municipalities, state/provincial departments, or national bodies, often establish regulations, codes, and standards that require or incentivize green building practices. These agencies may require certain energy efficiency standards, environmental considerations, or certifications to be met during the construction or operation of buildings.
2. Architects, Engineers, and Design Professionals: Architects, engineers, and other design professionals play a vital role in incorporating green building principles into the design and planning phases of a building project. They are responsible for integrating energy-efficient systems, sustainable materials, and environmentally friendly design features.
