It is normally known that buildings represent, on average, about 39% of worldwide energy consumption and 33% of GHG emissions. This eye-opening statistic just goes to prove the amount of power our built environment commands in this world
- Green Architecture: Green architecture (also known as sustainable design) is an approach to building that minimizes the harmful effects of the built environment by using resources efficiently and consciously. This includes things such as energy-saving appliances, renewable energy sources, and using sustainable construction materials.
- Declaration: Green architecture is a solution to the grim reality of an unsustainable future. Green architecture saves our planet, it also raises our standard of living by minimizing environmental damage, promoting the well-being of the occupants, and advocating for cost-effective construction.
1. Why Green Architecture is Important
➣ Reduced Energy Consumption
This is one of the essential objectives of green architecture to reduce the amount of energy spent by buildings, which can be done through these several design strategies and technologies.
- Energy-Efficient Home Appliances: Replacement of appliances that consume a large quantity of energy with those that do the same work with lesser energy will significantly bring down the total consumption of building energy. For example, ENERGY STAR-rated appliances are designed to be more energy-efficient than those without the rating.
- Natural Light Utilizations: Configurations that incorporate a vast quantity of windows and skylights with open floor plans provide maximum exploitation of natural light and offer the possibility of switching off artificial lighting during the day. This will not only save energy but will help create a much more pleasant indoor environment. Indeed, according to studies, this would cut down as much as 75% of lighting energy use. These natural lights are a good source of vitamin D to help absorb calcium, which is a basic constituent material for building strong bones.
- Effectively Insulated: Insulating the walls, roof, and floors helps to maintain the temperature indoors, thus minimizing heating and cooling. If insulation can be developed using materials like fiberglass, cellulose, and foam, it will sharply cut down heating and cooling energy requirements by up to 50%.
➣ Renewable Energy Integration
Green buildings often incorporate renewable energy sources to further reduce their reliance on fossil fuels:
- Solar Power Systems: The solar power system facilities will be able to meet a huge part of the building’s energy demands. Solar energy is unadulterated and renewable and can be exploited without greenhouse gas emissions. According to NREL, solar panels are estimated to save 50-75% on electricity bills on average. Solar power not only reduces energy costs but also provides significant long-term savings and environmental benefits.
- Wind Energy Turbines: These small-sized wind energy turbines can be located efficiently at a site where ample wind resources exist to create on-site renewable energy. It provides electricity without burning any fuel or polluting the air.
- Geothermal Heating and Cooling Systems: Geothermal heat pumps use the stable earth temperature in heating and cooling buildings. The technology, thus, will have the potential for 30-60% savings on both heating and cooling costs.
➣ Resource Conservation
Green architecture promotes resource conservation through sensitive design and the choice of materials:
- Use of Recycled Material: The use of recycled materials like reclaimed wood, metal, and glass lessens the demand for new material and helps redirect waste from landfills. For example, using recycled steel can save up to 75% of energy consumed toward the production of virgin steel.
- Efficient Water Management: Use low-flow fixtures, install rainwater harvesting systems, or enhance efficient irrigation systems to sophisticate efficient water management, drastically reducing the amount of bulk consumption by the building. These practices can reduce water use by 30-50%.
- Construction and Demolition Waste Reduction: It constitutes methods of waste reduction directly inflicted on construction through prefabrication and modular construction, thereby reducing the quantum of waste generated in the process.
➣ Lower Carbon Footprint
Green structures play a vital role in reducing carbon emissions by incorporating renewable energy sources, preserving resources, and consuming less energy. This is crucial in combating climate change and promoting sustainability
2. Health and Wellbeing Benefits of Green Architecture
➣ Improved Indoor Air Quality
Green buildings prioritize the health and well-being of their occupants by ensuring high indoor air quality:
- Ventilation Systems: Indoor pollutants are removed by proper ventilation and intake of fresh air. Mechanical ventilation systems, of which one type is what’s known as heat recovery ventilators, help maintain energy while providing a constant supply of fresh air. The World Health Organization says this can be as much as 20% lower for respiratory diseases.
- Non-Toxic Materials: Non-toxic, low-emission building materials will considerately bring down air pollution and help in the health improvement of the occupants in a building . These include formaldehyde-free insulation and low-VOC paints, among others.
➣ Increased Natural Light
The access to natural light has several benefits regarding occupant well-being, including:
- Mood and Productivity: The study proves that sunlight exposure improves mood, enhances output, and reduces anxiety levels. Two architectural features of high windows and open spaces, commonly used by green buildings, maximized the sunlight to a substantial extent. According to the American Psychological Association, having natural light can boost productivity by up to 15%.
- Health Benefits: An absorption of natural light will improve health and develop the quality of sleep. For its part, a night of good sleep might help improve cognitive functioning and lower the risk of chronic diseases.
➣ Thermal Comfort
Maintaining a comfortable indoor temperature is essential for occupant well-being:
- Energy-efficient heating and cooling systems: Green buildings seek to utilize the least amount of energy to reach constant temperatures, which the building inhabitants view as comfortable.
- Passive design strategies: Heat mass, natural ventilation, and solar thermal energy can ensure indoor temperatures remain within comfort zones independent of mechanical systems. This strategy will reduce the use of energy for cooling and heating by 50%.
3. Economic Benefits of Green Architecture
