The ideal green building would be a building project that would allow you to preserve most of the natural environment around the project site, while still being able to produce a building that is going to serve a purpose. The construction and operation will promote a healthy environment for all involved, and it will not disrupt the land, water, resources and energy in and around the building. This is the actual definition of a green building. The U.S. EPA says “Green building is the practice of creating structures and using processes that are environmentally responsible and resource-efficient throughout a building’s life-cycle from siting to design, construction, operation, maintenance, renovation and deconstruction. This practice expands and complements the classical building design concerns of economy, utility, durability, and comfort. Green building is also known as a sustainable or high performance building.” Most people will find when going green that they are able to reduce their carbon footprint and actually lend a helping hand to the environment. You can go green in a variety of different ways, but builders and construction workers must do their part as well. Green buildings are designed in such a way to reduce overall impact on environment and human health.
Indian Scenario: Facts and figures
According to thehindubusinessline.com With more than 350 building products securing green product (GreenPro) ratings, the market for such products is estimated at over ?18 lakh crore by 2022.As per the Indian Green Building Council estimates, these products, covering cement, glass sanitaryware and other materials that go into development of green buildings will be sought after as they are not only environmental-friendly, but also energy-efficient in the long term.According to experts at the Indian Green Building Council of the CII, more than 350 products have been thus far certified and this number is seen to quickly swell to over 400 and even go past the 500-mark.
Parasu Raman R, Chairman of CII-Green Products and Services Council, said that to unleash the potential of such products, the CII has launched Greenpro-Green Product certification, a first-of-its-kind eco label for building products in the country.C Shekar Reddy, Chairman of IGBC, Hyderabad, and Managing Director of CSR Estates, said the CII would play a facilitators role in popularising the green concepts and products. While working with state governments and various departments, the adoption of these products would be encouraged. Reddy said that the IGBC has taken to rating of metro projects and over 20 metro stations in Hyderabad have been rated till now. Of the over 5.2 billion sq. ft of buildings registered, about 1 billion sq.ft has been certified for green norms. The CII-IGBC is looking at achieving the ambitious target of 10 billion sq.ft by 2022, where the GreenPro rated products will play a crucial role.
According to economictimes, The US Green Building Council (USGBC) has announced the outcome of the Dodge Data & Analytics World Green Building Trends 2016 SmartMarket Report, in which the USGBC is a contributing partner. “The new report finds that by 2018, the green building industry in India will grow by 20 per cent driven largely by environmental regulations and demand for healthier neighborhoods,” USGBC said in a statement. New high-rise residential, communities and mixed-use development are expected to be the top three sectors for green building growth in India, it added. The report, conducted in nearly 70 countries, also demonstrates that global green building continues to double every three years. The report said the increase in consumer demand has pushed the world’s green building market to a trillion dollar industry, a surge that has led to a corresponding increase in the scope and size of the green building material market, which is expected to reach USD 234 billion by 2019. Green building programs such as LEED have been significant drivers of market transformation across the globe. Today, there are nearly 75,000 commercial projects participating in LEED across the globe, with 1.85 million sq ft of building space which LEED is certifying every day.
In India, there are more than 1,990 projects, comprising more than 822 million sq ft of space, participating in LEED. Building owners also report that green buildings — whether new or renovated — command a 7 percent increase in asset value over conventional buildings. Green Buildings are truly the need of the hour in India. If the country’s architects, builders, designers and the Indian Green Building Council (IGBC) have their way, most of the buildings in India (old and new) will soon turn environment-friendly, decreasing the amount of power they gobble. Currently, India has over 400 crore sq ft of registered green footprint, i.e. the second largest globally states https://www.moneycontrol report. By 2022, Indian Green Building Council (IGBC) is aiming 1000 crore sq ft of sustainable footprint. Now you may ask who is Indian Green Building Council (IGBC), let us discuss their story and why is there so much buzz around them.
Assertion of certification: Division according to segments
The dilemma that one could have is that how can one analyse the perfect achievement of green building standard. The assertion is about to clarified. Whether a Green building is really sustainable enough is to be decided against predefined rating systems. In India, Green Rating for Integrated Habitat Assessment (GRIHA), Indian Green Building Council (IGBC), and Bureau of Energy Efficiency (BEE) are the three primary Rating systems. The main purpose of any green building rating system is to guarantee that an existing or upcoming construction project incorporates the finest green building practices which would ensure constant savings and higher operation and processes.
The main goal of any green building rating system is to make sure that any existing or imminent construction project incorporates optimum green building practices which would ensure sustained savings and higher operations. Indian Green Building Council Green ratings are all-inclusive, user-friendly and strong and also offer the best services to its stakeholders. Green building rating brings together a host of sustainable practices and solutions to reduce the environmental impacts. Green building design provides an integrated approach considering life cycle impacts of the resources used. An important development in the growth of green building movement in India is the launch of the following IGBC Green Building Rating Systems:

The IGBC Green Building Certification Process
Online Project Registration:
Project owners aspiring for green building certification need to register online at www.igbc.in, indicating the built-up area, type of building, mode of payment of registration fee and their choice of the applicable rating system. IGBC then shares with them the required templates, important instructions and other necessary information.
A major step in the process is conducting a project feasibility study. This enables the project team to chalk out a roadmap for achieving the desired green building rating level. The broad areas that are evaluated during the study are:
- Sustainable Architecture and Design
- Site Selection and Planning
- Water Conservation
- Energy Efficiency
- Building Materials and Resources
- Indoor Environmental Quality
- Innovation and Development
The next major step is project facilitation. The green building consultant plays a vital role here. IGBC counsellors also hand-hold and guide the project team and the green building consultant during the facilitation process.
Green Building Design and Construction:
IGBC recommends that project teams should consider green building consultants who are IGBC Accredited Professionals (IGBC APs) for the overall feasibility study and facilitation process. IGBC APs are credible professionals who advise the project team on various eco-friendly concepts, technologies and products specific to the project.
Developer based projects have the choice to opt for precertification at the design stage. This results in optimization of costs and resources. Pre-certification also helps determine which credits and pre-requisites are likely to be achieved during the final rating. In addition, it allows developers to showcase the proposed green features to prospective tenants.
Documentation and Certification:
Documentation is a critical process towards achieving the desired green building rating. In view of its importance, IGBC permits project documentation to be submitted in two phases
- Preliminary submission
- Final submission
Preliminary phase submission includes the mandatory requirements and the number of credits that the project team aspires for. It is reviewed by a third party assessor appointed by IGBC for the specific project. Review comments are provided by IGBC to the owner/ project team within 30 days. The final submission includes clarifi cations for preliminary review queries. IGBC provides review of the final submission also within 30 days, after which it awards the rating.
To achieve an IGBC Green Building Rating, the project must satisfy all the mandatory requirements and the minimum number of credit points in each section. The project team is expected to provide supporting documents at preliminary and final stages of submission for all the mandatory requirements and the credits attempted. The project needs to submit the following:
- General information including the project brief, project type, different types of spaces, occupancy schedule, number of floors and area statement.
- General drawings including the master/site plan, parking plans, floor plans, elevations, sections, photographs
- Filled-in templates available in the IGBC rating manual.
- Narratives and supporting documentation such as drawings, calculations (in excel sheets), declarations, contract documents, purchase invoices and manufacturer cut-sheets/ letters/ material test reports for each mandatory requirement and for each credit attempted.
IGBC, through a third party assessor team, carries out a detailed physical audit of the project to ensure that it meets all the requirements for the rating. At this stage, IGBC counsellors advise the project team on the scope for further improvements. Physical audit is usually conducted when about 20-30% of the project work is completed. This provides an opportunity to the project team to take stock of the progress made, and to look at the possibility of incorporating suggestions made by the audit team. In addition, IGBC collects energy and water performance data annually from all certified projects to ensure that they are able to achieve sustained performance as envisaged at the design stage.
Final Award of Rating: After verifying all the documents and submittals of the project team, IGBC awards a final rating to the project. Following are the levels of rating:
