When one mentions a Green building, the reference is specifically made to a structure and the processes involved that are, being environment-friendly and resource-efficient throughout the building’s life cycle—from site to its design, construction, operation, maintenance, renovation and demolition of everything. At all project stages, the architects, engineers, and clients must collaborate to create a sustainable, eco-friendly project.
Simultaneously with the development of new technologies, the current practice is to create greener structures, with the common goal of designing green buildings to reduce the overall impact of the built environment on human health and the natural environment by
1. Using energy, water, and other resources efficiently.
2. Improving staff productivity while protecting occupant health
3. Reducing waste, pollution, and destruction of the environment
The green construction strategy is more than just about lowering energy use and increasing indoor air quality; it’s about treating the entire system, not just the parts. A more thorough strategy should be taken in this regard. Climate change as a result of global warming has become critical on a worldwide scale. High temperatures, copious precipitation, and rising sea levels are all signs of global warming resulting from increased greenhouse gas emissions.
Countries are focusing on the building industry in their efforts to reduce pollution. They also control construction materials and heavy machinery, demanding that builders use environmentally-friendly equipment. Professionals who use sustainable building methods gain enormously.
The high emission rates of material manufacturing techniques and heavy machinery are a prevalent ecological challenge in the construction industry. Stormwater runoff from construction projects also harms the environment, driving up demand for environmentally friendly construction.
One of the most noticeable benefits of using environmentally friendly construction methods is the reduction of carbon emissions. The construction and operation of buildings account for 39% of worldwide greenhouse gas emissions. Less ecologically friendly structures have lower real estate values and higher maintenance costs.
Reducing residential and commercial buildings’ emissions also reduces air pollution’s harmful health consequences. Breathing this air raises the risk of cancer, stroke, heart attacks, and other health problems in construction workers and residents. It also increases a person’s chances of having an asthma attack, chest pain, or shortness of breath.
Using sustainable building materials and environmentally friendly construction equipment also provides low-emission benefits to builders. Electric excavators, which reduce emissions on construction sites, are being developed by several manufacturers to support sustainable demands.
According to evidence, building owners, operators, and tenants benefit financially from sustainable structures. Annual energy, water, maintenance/repair, churn (reconfiguring space due to changing needs), and other operational expenses are often lower in sustainable buildings. These savings don’t have to come at more considerable upfront costs. The initial cost of a sustainable building can be the same as, or lower than, that of a regular structure, thanks to integrated design and the inventive use of eco-friendly materials and equipment. Some aspects of the sustainable design involve higher upfront expenses. Nonetheless, the payback period for incremental investments is frequently quick, and the lifecycle cost is typically cheaper than that of more traditional buildings.
Eco-friendly buildings can bring indirect economic benefits to both the building owner and society and direct cost reductions. For example, environmentally friendly, sustainable building features can improve building occupants’ health, comfort, well-being, and productivity, lowering absenteeism and improving productivity. These features can provide owners with financial benefits such as reduced risks, longer building lifespans, improved ability to attract new employees, reduced expenses for dealing with complaints, less time and lower project costs, and increased asset value as a result of community acceptance and support for sustainable projects. Environmentally friendly buildings also benefit society economically, such as decreased air pollution costs and cheaper infrastructure expenses, such as avoided landfills, wastewater treatment plants, power plants, and transmission/distribution.
