With the technological development, man has extended its arm beyond its extensions and founded the heavy engineering building concept such as Green Building Concept. In fact, this attitude of conquering the limits sets a new goal for the man to overcome. It is subsequently raising the ability of man to go beyond the boundaries. But somewhere down the line, we are creating the grave for ourselves. The concern behind the rapid growth inability of humans in exploiting its natural resources has been continuing since the early stages of industrialization, and this is creating an enormous climatic and health concerns. But the implementation of sustainable technique was much thin as compared to its concerns. In 1962, Rachael Carson published the book entitled “Silent Spring” made the first initial effort to describe sustainable development as related to the term green building.
Green building concept is a movement that is linked to the sustainable construction techniques. The Green building concept originated from the need and desire for creating and constructing those structures which justify the primary motive of sustainable construction. A green building concept is an approach that aims at the encouragement in designing and constructing that architectural excellence. It uses less energy but optimizes the energy efficiency, use less water, create a less adverse effect on the existing environment, generates fewer wastes and do not emits harmful emissions to the atmosphere neither in the present nor the future. The thus green buildings concept is implemented in design to reduce the overall impact of the building not only on the environment but also on the human health.
The green building concept culminates a vast array of techniques, practices, and skills which bridge the gap between the construction and sustainable construction taking the concerned objectives of a classical structure such as economy durability, availability of energy resources, flexibility, and friendliness to the inhabitant.
Over the years, according to various researchers, they found that the green building concept is making a greater impact on the minds of the builders, architects, and most importantly it could deviate the minds of the owners towards itself from the classical concept of the building. The international council has released a publication that estimates that the existing buildings are responsible for more than 40% of world’s total primary energy consumption.
Why has built Green Building?
Green building concept has evolved from its early stage to a dominant stage over the years with its evolution. It has created a new set of a community of great brains that focuses on bringing in new ideas, techniques, methods and skills to uplift the green building concept and allows it to cement its position in the field of construction. However the practices or techniques implemented in green building concept are constantly evolving and may differ from country to country and region to region, but the fundamental principles continue from which the method originated. But the prime goal of green building concept can be enumerated as follows:
- Water efficiency.
- Material efficiency.
- Indoor environmental quality enhancement.
- Waste reduction.
- Toxic reduction.
- An overall reduction in embodied energy.
- Site and design efficiency.
How To Persist Green Building Concept:-
- Maximum use of renewable sources of energy
- An effort to create scope for the highest use of non-impactful materials concerning health and environment.
- Constructing new buildings and renovating the existing building according to the guidelines of LEED (Leadership in Energy and Environmental design).
- Before going for any material for construction a proper research, evaluation and selection procedure should be followed to proclaim the green building concept into reality.
What is LEED?
LEED stands for Leader in Energy and Environmental Design. LEED is a rating system devised by the United States Green Building Council (USGBC) to evaluate the environmental performance of a building. LEED, on the other hand, encourages the market to accept the sustainable way of development as their prime objective and the green building concept.
LEED is a point-based rating system that allocates points to the constructional projects for implementing environment-friendly steps during the construction and measures the effects on the environment during the life of the structure.
The LEED Certification is one done on the following point basis. Below we are providing you the LEED certification level.
- Certified 40 – 49 Points
- Silver 50 – 59 Points
- Gold 60 – 79 Points
- Platinum 80-110 Points
LEED is a voluntary program; however, obtaining a LEED certification projects is an environmentally active reflection to the community. After the introduction of LEED, most of the constructional projects tries to attain the highest level of LEED certification by implementing the best method and technology that suits aim of environment-friendly construction. Most of the top construction companies in India and across the globe are concentrating more on the green building concept, methods and green building technologies as this give them the additional credit for their construction practice.
What Are Green Building Materials?
Materials are those materials which help in persisting the goals of green building are known as green building materials. The introduction of this material in the field of construction has been done to justify the initiatives that are taken to safeguard our environment. These green building material are environmentally responsible for diminishing the overall impact over its lifetime. Therefore, most of these green building materials are alternatives to the non-renewable.
One of the major criteria that reflects the total amount of carbon emission caused by a material is the calculation of embodied energy. Embodied energy is the total quantity of carbon dioxide emitted by a material ever since its first step to manufacturing till its lifetime. The lower the total embodied energy, the higher it is environment-friendly.
The construction of any structure requires a variety of materials. The selection of these materials is on of the major toward the persisting the goal of green building. The choice should be made in such a way that the quality and standards of the building could be satisfied with the regulation of green building technology.
The use of green building material not only environmentally beneficial but also offers specific benefits to the occupants and owners. Some of these benefits are enlisted below:
- Reduces maintenance or replacement costs over the lifetime of the building.
- Helps in conserving energy.
- Gives better aesthetic significance.
- These materials are friendly from the occupants health point of view.
- According to various market researchers, the green building materials cost less due to less consumption of energy, water, and lower costing in maintenance than the conventional building materials.
- Gives Greater design flexibility to the designers.
