Introduction
Sustainable building, also known as Green building or eco-friendly building, has gained significant attention in recent years due to its potential to address the growing environmental challenges, and climate changes and promote sustainable construction and improve the living condition of the occupants. It focuses on the efficiency and sustainability of buildings and seeks to reduce their negative impact on the environment during their construction and lifetime use. It encompasses a holistic approach to the design, construction, and operation of buildings that prioritize energy efficiency, water conservation, resource efficiency, indoor environmental quality, site and location considerations, and social well-being.
In this article, we will explore the concept of green buildings. We will discuss what is a green building, its features, advantages, and criteria for certification. We will also discuss how green buildings can benefit individuals and the environment.
What is Green Building?
Green Building refers to the practice of designing, constructing, and operating buildings in an environmentally and resource-efficient manner to minimize their negative impact on the environment and humans and promote sustainable living. These structures are designed with the goal of reducing their overall impact on the environment and its resources. Green building avoids the use of hazardous materials and energy in construction while encouraging smart and sustainable design.
The main features of green building involve resource efficiency, proper site selection, respect for local/indigenous culture, water conservation techniques and renewable energy systems, among other elements and typically feature an efficient HVAC system to reduce energy consumption.
Ultimately, these buildings aim to improve the quality of life of the occupant and reduce the negative impact on the environment. This is achieved by providing healthy spaces that preserve the environment’s natural resources while also providing a comfortable living space or workplace.
Key Features of Green Buildings
Green building is a product of conscious efforts to design, construct and nourish sustainable buildings that take into account their local environment to create a healthy living space. The concept of Green Building aims to reduce the negative environmental impacts of a construction project while increasing user comfort and well-being. To achieve this, the green building integrates various key principles into the design and construction process:
- Resource Efficiency: promoting the preservation of natural resources from overexploitation by implementing the use of shared resources in or around nearby areas. And the use of sustainable materials such as wood for construction.
- Water Efficiency: Reducing water usage through efficient installation such as rainwater harvesting, low-flow fixtures, greywater recycling, and proper plumbing system designed to minimize water wastage.
- Indoor Environmental Quality: Creating a healthy and comfortable indoor environment for occupants such as ensuring proper ventilation, using low-toxic materials for finishes and furnishings, and promoting access to natural daylight and views in order to improve the well-being of the occupants.
- Sustainable Site Development: Protect ecosystems during the development of the site by optimizing land use and preserving natural features. This includes strategies such as preserving natural habitats, promoting biodiversity through landscaping, reducing light pollution, and providing access to public transportation.
- Energy Efficiency: Green buildings must make use of renewable energy sources and increase energy efficiencies, such as installing solar panels or geothermal systems. They should also minimize water consumption, particularly with regard to water heating and cooling. Furthermore, they ought to employ high-efficiency building systems by reinforcing insulation, air-sealing techniques, and mechanical systems.
- Minimal Carbon Footprint: Reduce carbon footprint by incorporating energy-efficient design and technologies such as high-quality insulation, efficient HVAC (heating, ventilation, and air conditioning), and reduce greenhouse gas emissions.
Benefits of Green Buildings
The concept of green building is an excellent way to reduce our impact on the environment and create a healthier living space – but what are the benefits?
Environmental Benefits
The concept of Green buildings provides tremendous environmental benefits. From reducing energy usage, water consumption, and waste production to using renewable sources of energy, green building practices conserve precious natural resources. By reducing the amount of energy required to operate a building, carbon emissions are also reduced, thus mitigating their environmental impacts.
Social Benefits
Green buildings also benefit society. They reduce air pollution, and noise pollution and can help to improve the quality of life in urban areas by promoting ecotourism, introducing safe recreational spaces, and providing access to clean drinking water. Additionally, green buildings can also be used as educational tools for students and community members alike.
Health
In addition to their impact on the environment and society, green buildings also have an impact on human health. Green buildings are designed with healthier indoor air quality in mind using pollutant-reducing products such as low VOC paints and adhesives; increased ventilation; improved thermal comfort; better sound insulation; LED lighting designs that minimize glare; and other materials that reduce exposure to hazardous substances.
Economic
Finally, green buildings are also known to provide economic benefits such as lower utility costs due to efficient use of energy; savings from reduced waste management costs; tax incentives for environmentally friendly builds; greater real estate value through higher tenant satisfaction scores; increased employee productivity due to improved working conditions; and long-term cost-savings through sustainable structures with extended lifespans.
Certification and Green Building Rating System
Achieving green building certification can take a few different paths, depending on where the structure is located around the world.
LEED Certification
In the United States, Leadership in Energy and Environmental Design (LEED) is the gold standard for green building certification. The LEED rating system includes six credits—energy and atmosphere, water efficiency, materials and resources, indoor environmental quality, location, and innovation—which are awarded based on how well each building meets the criteria to create sustainable living and working spaces.
IGBC Certification
In India, certification for Green building can be obtained by registering and qualifying the mandatory requirements set by the Indian Green Building Council ( IGBC). The IGBC certification process follows a holistic and multi-pronged approach to ensure the best green building practices are incorporated for sustained savings and enhanced operations. These rating systems include ancient architectural practices and modern technological innovations and prioritize national goals such as the conservation of resources, water and energy efficiency, waste management, and occupant health.
Global Green Building Rating Systems
In other parts of the world, green building assessment systems and rating systems also exist. In India, for example, a voluntary program called GRIHA evaluates buildings based on their energy performance and environmental friendliness. The China Green Building Council (CGBC) provides a rating system for sustainability in buildings across Mainland China as well as Hong Kong and Macau. Similarly, the Japan Sustainable Building Consortium (JSBC) evaluates Japanese structures for environmental performance.
The criteria for sustainable design differs from country to country—but the end goal is aimed to create buildings that minimize their impact on the environment while maximizing energy efficiency.
Conclusion
While the concept of green building has many obvious benefits, green certification and building criteria are essential in order to guarantee the highest level of performance and results. The growing demand for green buildings is an indication that the construction industry has embraced the concept and is recognizing the importance of sustainability and environmental stewardship. The long-term benefits of green buildings cannot be understated, and will increasingly be sought after in the future. Green buildings are not only beneficial to the environment but are also cost-effective and can provide significant savings in energy, water, and maintenance costs. Furthermore, green buildings can also provide improved occupant comfort and health, as well as higher productivity and better indoor air quality. As green building criteria and certifications continue to evolve, it is important to keep up to date with the latest developments to ensure successful results.
