- The energy crisis in the 1970s led to the emergence of energy-saving technologies like solar, geothermal, and wind energy.
- In 1992, the United Nations Conference on Environment and Development promoted sustainable development and green buildings.
- In 1993, the United States established the Green Building Association.
- Various countries (Hong Kong, Taiwan, Canada, Singapore, and China) introduced standards and measures for green buildings at different points in time.
What is Green Building?
- Green Building is also called sustainable or green construction.
- Expanding upon building design considerations of cost, performance, durability and comfort.
- Using less water, optimized energy efficiency, conserved resources, reduced waste and healthier spaces for building occupants.
- Focus on reducing overall impact on human health and natural environment.
- Efficient use of energy, water, and other resources.
- Reducing waste, and pollution to mitigate environmental impact.
Green Building Concept
- The concept includes site planning, design optimization, energy optimization, performance, renewal energy utilization, water and waste management, sustainable materials, construction technology, health and well-being, and environmental quality.
How to Make Green Building
- Sustainable site planning with bioclimatic architectural design
- Energy-efficient lighting, heating, ventilation, and air conditioning (HVAC) systems
- Using low-energy and renewable materials.
- Using construction materials and interior finishes that have minimal emissions.
- Implementing dimensional planning and material efficiency strategies.
- Utilizing gray water systems for recovering rainwater for site irrigation and dual plumbing systems for recycled water.
Need in Present Scenario
- Buildings account for a substantial portion (40%) of global energy consumption and are a major source of greenhouse gas emissions, more than the transport and industry sectors.
- Significant waste is generated during building construction.
- Buildings consume significantly more energy than transportation in the US
- Buildings account for a considerable portion of electricity and water use in the US.
- Indoor pollution levels in buildings are often higher than outdoor levels.
Objectives of Green Building
- Protecting occupant health
- Improving employee productivity
- Using energy, water, and other resources efficiently
- Reducing overall environmental impact
- Optimal environmental and economic performance
- Providing satisfying and quality indoor spaces
Benefits of Green Building
- Environmental: Protecting biodiversity, improving air and water quality, reducing waste, conserving resources.
- Economic: Reducing operating costs, creating and expanding green product markets, improving occupant productivity.
- Social: Enhancing occupant comfort and health, improving aesthetic qualities, minimizing strain on infrastructure, and improving the overall quality of life.
Features of Green Building
- Minimize disturbance to landscapes and site condition
- Use non-toxic, recycled/recyclable materials
- Efficient energy and water recycling systems
- Use environmentally sound energy technologies and equipments
- Good indoor air quality
- Effective building controls and management systems
Merits of Green Building
- Efficient technologies, easier maintenance, return on investment, improved indoor air quality, energy efficiency, water efficiency, waste reduction, temperature moderation, water conservation, economical construction for the poor, healthier lifestyles and recreation, and improved health.
Demerits of Green Building
- High initial cost
- Limited material availability
- Longer construction time
- Need for skilled labor
Green Building Ratings
- A green building rating system is an evaluation tool to measure a building's environmental performance throughout its life cycle.
- The system comprises evaluation criteria covering the building's design, construction, and operations.
- Each criterion has assigned points reflecting performance and related goals.
- Projects earn points based on meeting the criteria, then are rated based on the accumulated points.
- Globally, green building ratings are often voluntary but have increased awareness and popularized green building designs.
Green Building Ratings (Specific Systems)
- BREEAM: Building Research Establishment's Environmental Assessment Method, developed in the UK in 1990.
- GBTool: Developed by the International Framework Committee for the Green Building Challenge (an international project involving more than 25 countries) since 1998
- LEED: Leadership in Energy and Environmental Design, developed in the US in 1998.
- CASBEE: Comprehensive Assessment System for Building Environmental Efficiency, developed in Japan in 2001.
- IGBC: Indian Green Building Council, formed in 2001.
Fundamental Principles
- Structural Design Efficiency: Sustainable building concept aiming for lowest cost, best performance, and lowest environmental impact throughout all stages of the building's life.
- Energy Efficiency: Building design that strategically utilizes natural resources (light, heat) to reduce reliance on artificial heating and air conditioning.
- Water Efficiency: Reuse, purify and reuse collected water to minimize water usage.
- Material Efficiency: Use recycled materials to reduce waste, and generate additional surplus energy.
- Waste and Toxic Reduction: Reuse materials considered waste to reduce the consumption of resources which might be able to be reused.
