Building The Green Way - Green Building Eco Friendly
The growth and development of Building the Green Way Of our communities have a profound impact on our natural environment.
The production, design, construction, and operation of the buildings in which we live and work are responsible for the use of our many natural resources.
Buildings worldwide use more than 40 percent of energy consumption and about a third of greenhouse gas emissions. The United Nations Environment Program says that if we continue to do business as usual in the construction industry, this pollution will more than double by 2030.
These numbers are alarming. The impact on the environment is immense and it’s high time we as a community take some actionable decisions for the same.
One big step is to switch towards Green Buildings and sustainable construction methods. This blog explores the concept of green construction in detail.
What is a Green Building?
Building The Green Way, or sustainable design is the practice of increasing the efficiency with which buildings and their sites use energy, water, and materials, and of reducing impacts on human health and the environment for the entire lifecycle of a building. Green-building concepts extend beyond the walls of buildings and include site planning, community and land-use planning issues as well.
Why Green Buildings?
The answer lies in the picture below.
How to build the Green Way?
1. Using the right materials:
Green building materials include wood from well-managed and certified forests, fast-growing plants such as bamboo and grass, used stones or metal, and non-toxic materials that can be reused or recycled in other construction projects.
Carpet handling should be done with recycled materials or natural fibers such as wool or seagrass, and solid wood should use certified wood as a sustainable control, or bamboo or fast-renewable cork. Real linoleum made from cork dust, limestone, and linseed oil rots. Stone, ceramic, or glass tiles can be repaired or restored.
2. Insulation medium:
Most of the building’s insulation materials, key to energy efficiency in a building, are made of petrochemicals. They come in sheets or blankets made of recycled fiberglass, cellulose, denim or mineral wool; Instead insulation can also be made of natural fibers such as wool, flax, hemp, cellulose, wood fiber, or clay pellets.
3. Improving Indoor Air Quality:
When buildings are airtight, good ventilation is essential to allow fresh air to come in from the outside and stale air to leave through vents, or air to be recirculated and filtered. Ventilation and insulation also control moisture, which can lead to mold and bacteria growth if not checked. Demand-controlled ventilation can use occupancy sensors or CO2 sensors to adjust fresh air intake to the needs of the building occupants.
VOCs have harmful impacts on health and comfort, so green building attempts to use construction materials, interior finishes and paints, and cleaning products with low or no VOCs. Unlike most paint, coatings made of natural materials like clay, lime, linseed oil, chalk, milk protein, plant or mineral dyes, and natural latex are generally non-toxic.
4. Sustainable Roofs andWalls:
Many traditional rooftops can be up to 90˚ hotter than the surrounding air temperatures, especially in cities. Cool roofs, which reflect solar heat instead of absorbing it, lower temperatures inside a building, reduce the need for air conditioning and thus energy costs, and require little maintenance.
Green infrastructure on roofs and walls offers many benefits. Green roofs are very effective at saving energy, improving air quality, and helping to manage stormwater.
They are usually constructed of a top layer of vegetation, soil, a root barrier, drainage, and layers to protect the roof itself and support the weight. Green roofs can be cooler than the surrounding air temperature because they provide shade, and as plants absorb water and evaporate it, the air is cooled.
They can reduce the cost of air conditioning by 25 percent, lessen air pollution by collecting fine dust pollutants, increase biodiversity, help manage stormwater by absorbing precipitation, and provide aesthetic enhancement. Some green roofs also grow food.
5. Placement ofWindows:
Window placement in relation to the angle of the sun can affect the energy efficiency of a building as well as heating and cooling costs. Windows facing east and west allow in more heat than windows facing north and south.
Smart windows can change from transparent to translucent when low voltage electricity passes through them, altering the wavelengths of light that can pass through. While they are more costly, they can save money on heating, air conditioning and lighting, and avoid the need for blinds or curtains.
6. Efficient lighting:
Since most people spend 90 percent of their time indoors, lighting is critical. Daylight should be allowed to come into the building as much as possible while ensuring that there are blinds or shades to reduce excess heat from windows and skylights. Incandescent bulbs are being phased out; compact fluorescent lamps and LED bulbs to use less energy and last longer.
7. Deploying Solar Energy:
Passive solar technology or daylighting depends on window placement, the use of thermal mass, and the building’s proper orientation to the sun to provide light and heat without any other apparatus.
Windows that face south and open interior spaces bring sunlight into the building. A thermal mass, such as water, brick, concrete, or adobe, stores warmth when the sun hits it, then releases the heat gradually at night. A thermal mass such as marble, if kept out of the sun, will help keep a building cool.
Solar water heaters use solar power to produce hot water. Solar photovoltaic panels on the roof or building exterior convert solar power to electricity. They can be made of various materials that alter their efficiency, including new thin-film flexible solar cells that are cheap and non-toxic.
Solar power provides energy independence, and once installed supplies free and clean energy; the disadvantages are that the power can fluctuate, and systems can be costly to install, though there are many tax credits and incentives available.
8. Water Management:
Globally, buildings use 13.6 percent of all potable water, so reducing water consumption is a key aspect of green buildings. Water can be conserved with ultra-low flush toilets and low-flow faucets. Greywater systems recycle water that comes from washing machines, sinks, or dishwashers.
Green landscaping attempts to keep the natural features intact, using native plants and grasses, which require less water.
Plants should be fed compost instead of chemical fertilizers. Drip irrigation, which waters the plants at their roots, wastes less water than sprinklers, and rainwater can be collected in barrels for watering plants. Composting should be practiced to minimize waste going to the landfill and produce nutrient-rich humus for the soil.
Green infrastructure, such as bioswales and rain gardens, depressions planted with vegetation, absorb runoff and allow it to infiltrate the ground and replenish aquifers. Permeable pavement or pavers with the spaces in between filled with grass or stones, also allow rainwater to be absorbed.
“Being green is more than just buying ‘eco’. It is an unshakable commitment to a sustainable lifestyle”
It is time, we prioritize our environment and planet above everything else and promote sustainable development. Every little contribution counts!
