GREEN BUILDING : A NEW WAVE IN INDIA
India is experiencing anincredible growth in the construction and real estate industry. Due to this rise in the construction sector raised many issues related to the environment and sustainability.As per economic policy forum, in its report mentioned that in India the energy consumption in buildings is for heating, ventilation and air Conditioner accounts for between 45% and 65% of total electricity consumption. Another study states that the construction sector of India emits about 22% of the total annual emission of CO 2 which is very harmful for the environment. So to handle the adverse situation a new and important concept is emerging in India that is Green Building. So this article gives you the understanding about the green buildings, How the green building get rating from the rating agencies, Importance of green buildings, and examples of some companies and organization that are taking the advantage of green wave and is flourishing.
Historical Perspective and Concept of Green Building in India – A Review
2017
The concept of green building has created an immense importance in a developing country like INDIA. The theory implies of minimizing the wastage and the cost of construction. Green Building encompasses a wide range of design practices, building systems integration, product specification, and construction techniques Green building approach is consistent with the mission of most affordable housing developers, and the most community development corporation mission statements which include language about ensuring that low income people have access to safe, decent and affordable housing. The concept of green buildings is not as emerging as we think it is. The Evolution of housing started by utilizing nature and natural resources like trees and caves as shelter from the severity of natural elements like sun, rain, wind, etc. Based on such complex experiences, our Vedic philosophy evolved certain methods to maximize the use of Panch Mahabhuta or the 5 basic elements of nature, i.e., Jal (w...
Change in climate, caused by the release of greenhouse effect causing gases (primarily carbon dioxide) into the atmosphere, has been recognized as one of the greatest threats of the 21st century. Share of the global energy consumption in India and China has also been on the rise due to heavy industrialization, urbanization, population explosion, and intensive growth of IT. Buildings are the prime energy consumers in modern cities accounting upto 40 to 45% energy consumption. Their consumption can be largely confined through improving efficiency, which is an effective means to lessen greenhouse gas emissions and slow down depletion of fossil fuels. There is a heavy (over 50%) saving potential in the building sector and thus it is considered as a potential sector to meet the challenges of global energy demand and climate change. Along with the advent of energy efficient measures, more effective means are needed to induce or compel greater efforts, especially to the signatories of the Kyoto Protocol. This technical paper highlights the importance of sustainable construction, discusses role of energy efficiency in green buildings in Indian context to reduce the energy consumption and environmental degradation through Green House Gas emission (GHG). Also it points out to the benefits of green construction as well as the incentives from govt. and municipal bodies for GRIHA certified green building.
GREEN BUILDING REQUIREMENT IN INDIA AND FACTORS DRIVING GREEN BUILDING PURCHASE
Environmental pollution has reached a stage wherein it cannot be left alone to the natural environment to heal by itself. Human interventions have become absolutely necessary to control environmental pollution and reduce the impact of damage to the environment. One large contributor to environmental pollution is the construction industry. The improper use of natural resources in construction on buildings, the energy consumed and the dispose of the salvage largely impacts the environment. There is a huge concern to reduce the impact of buildings on the environment. This concerns for the environment have in fact led to the thought process of construction of green buildings which minimize the impact of the buildings on the environment. In order to minimize the environmental impact of the buildings it is high time to follow guidelines and necessary steps for undertaking the task of construction of green buildings. The researchers in this paper talks about the requirement of green building constructions in India, and tries to find out the drivers which create a demand for purchase of green buildings.
Green Building Development for Sustainable Environment with Special Reference to India
Building materials and technologies, and building practices have evolved through ages. The following points require attention, regarding the use of modern building materials: energy consumed in the manufacturing processes, problems of long distance transportation, natural resources and raw materials consumed, recycling and safe disposal, impact on environment, and long-term sustainability. Thus the issues related to energy expenditure, recycling, biodegradable, environmental and sustainability with respect to future demand need to be addressed during the manufacture and use of any new building material by the practice of increasing the efficiency with which buildings use resources energy, water, and materials while reducing building impacts on human health and the environment, through better site, design, construction, operation, maintenance, and removal i.e. the complete building life cycle for achieving sustainable building development or green building development. The goal of the "green building" project is to reduce the impact of construction on the environment by sustainable building and construction of buildings using methods and materials that are resource efficient and will not compromise the health of the environment or the associated health and well-being of the building's occupants, construction workers, the general public, or future generations. Sustainable building involves the consideration of many issues, including land use, site impacts, indoor environment, energy and water use, solid waste, and lifecycle impacts of building materials. Energy consumption and associated greenhouse gas emissions will therefore continue to rise unless actions to direct the construction industry towards sustainable consumption and production are taken urgently.
Green Building Systems in the NCR Region of India
2019
Green building rating systems (GBRS) result in energy-efficient and environment-friendly buildings. They not only preventpollution and resource wastage during construction ; but also uphold high indoor air quality, energy and water efficiencies throughout the building life-cycle. The economic growth of Indian cities has led to hasty construction activities causing resource challenges, air pollution and congestion. The aim of the paper is to find the greenest building in the National Capital Region (NCR) ,which can be a benchmark building for the new buildings in the region. The paper presents the case study of two greenest buildings in the NCR from the two different GBRS; and also compare their attributes and rating systems. The paper inferscritical energy efficiency, air quality and water efficiency attributes of these benchmark buildings much needed in rapidly growing cities like NCR.

Urban expansion in India is enormous and will place great pressures on natural resources, especially water and the atmosphere. There are significant opportunities to reduce these pressures and contribute to human development through green building. The regulatory framework for green building, with the adoption of Part 5 of the National Building Code, complemented by voluntary codes and green building rating systems, will provide adequate guidance for the expansion of green buildings in the short-term. Standards for resource-efficient building materials need to be developed. The capacity to design and construct green buildings needs to be strengthened. More information about the actual costs and benefits of green buildings needs to be disseminated.
Green Building Rating system in India & Studying the long-term effectiveness of Green building
The building sector is one of the biggest consumers of electricity in India [1] ; it is also the largest generator of CO2 emission & one of the highest consumers of water in India. This is the basic reason why Green building movement comes to India so that we can minimise the environment effect caused by the construction activity in India. Green buildings have potential to reduce up to 34 percent lower CO2 emissions, consume 25 percent less energy and 11 percent less water, and have diverted more than 80 million tonnes of waste from landfills [2]. The author of this paper has studied different rating systems in India & the sustainability of the green buildings in India. The paper goes beyond Green building rating system and gives a thought to the understanding of embedded emission and operational emission. The author of the paper gives an idea of not only Green Building but also a sustainable green building by Post occupancy evaluation.

Buildings have major environmental impacts over their life cycle. Hence, there is a need to design and construct a green building which minimizes the issues related to environment deteriotion due to construction of buildings. A green building uses less energy, water and natural resources. It generates less waste and provides a healthy living environment for the occupants. The construction industry is a larger user of natural resources, therefore there is a need to design building with low environmental impacts. Green buildings are upcoming concept and the need for present day construction industry, so as to have sustainable development. It has been observed that Vadodara city has witnesses a remarkable growth in the construction of commercial as well as residential sectors. The concept of green building has been more widely adopted in commercial sectors rather than residential sectors. Hence, a study was conducted to find out the opinion of the builders regarding adoption of green building concept in their construction of residential sectors, reasons for adopting the green building concept and the barriers faced in adopting the same. The data were gathered through a questionnaire from a sample of 75 builders through convenience sampling. Descriptive and relational statistics was used for presenting results. The findings of the study revealed that majority of the builders were middle aged and their professional association was the main source of information about green buildings. More than one half of the builders had low extent of exposure to various sources of information. Environmental aspects were the reason as stated by builders behind the adoption of green building design and construction. Majority of the builders faced lack of technical knowledge of the project team, contractors and clerk and lack of interest in implementing green building concept as high extent of barrier in adopting green building design and construction. Majority of the builders had somewhat favourable opinion regarding green building. A significant relationship was found between reasons for adopting green building design and construction by the builders and opinion of builders regarding the same. The builders can be made aware through an educational programmegiven by the educational institution about the impact of the buildings on the health of the occupants and to construct a building which incorporates features of green building.
Today we all have heard the term " Green Building " more and more often just because the Green Movement is getting more and more popular with each passing year. A green building is the one which uses less water, optimises energy efficiency, conserves natural resources, generates less waste and provides healthier spaces for occupants, as compared to a conventional building. The " built " environment has a vast impact on the natural environment, human health, and the economy. By adopting green building strategies, we can maximize both economic and environmental performance. Green construction methods can be integrated into buildings at any stage, from design and construction, to renovation and deconstruction. In the year 2001, the Indian Green Building Council (IGBC), formed by Confederation of Indian Industry (CII) is continuously striving towards wider adoption of green building concepts in our country. It has licensed the LEED (Leadership in Energy and Environmental Design) Green Building Standard from the U.S. Green Building Council and at present certifies the LEED-New Construction and LEED-Core and Shell buildings in India. The Energy Conservation Building Code (ECBC) was launched by the Indian Bureau of Energy Efficiency (BEE) as a guide for energy efficiency standards. The Green Building movement spearheaded by CII-Sohrabji Godrej Green Business Centre in Hyderabad since 2001 has come a long way. With a meagre green building footprint of 20,000 sq.ft in 2003, today over 400 million sq.ft have been rated by IGBC. India ranks third among the top ten countries for LEED and in 2016, nearly 650 projects in India earned LEED certification. According to a recent USGBC survey, 87 percent of Indian professionals anticipate that use of LEED in India increasing overall, with nine out of ten industry senior executives in India anticipating that their LEED related work will increase over the next several years. The effective use of the natural resources is the need of present days. The Indian green building movement is surging ahead and well poised to reach greater heights, in the years to come.
