International Journal of Scientific & Engineering Research, 2018
The growth and development of our society has a large impact on our natural environment. The research, design stage, construction and operation of the buildings in which we live and work are responsible for the consumption of many of our natural resources. The rating systems set benchmarks for green initiatives for constructing and using buildings to make them sustainable and energy efficient buildings thus to reduce their negative impacts on environment. The most recommended green building evaluation criteria in India are Leadership in Energy and Environmental Design (LEED), Indian Green Building Council (IGBC) and Green Rating for Integrated Habitat Assessment (GRIHA). This paper focus on the study of LEED, IGBC and GRIHA rating system and compare those rating systems with regards to their evaluation methods; scopes, performance criteria and energy rating measures. Through this study, an attempt is made to make clear understanding of LEED, IGBC and GRIHA rating system evaluation criteria that need to be considered during comparison. From this comparative study one can make a general checklist study which cover each and every aspect required for evaluation and certification for any building project.

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.
Comparative Review of Indian Green Building Rating Systems
Indian construction industry is witnessing highest growth rate from last 10-15 years, which is having a negative impact on the environment and natural resources available for construction. Following this problem of carbon imprint, concept of sustainable development in construction industry is the need of an hour. With increase in demand of sustainable buildings or Green buildings, demand of Green rating and assessment tools is also increasing. Rating tools set benchmark for green building measurement, which are helpful in reducing negative impact on environment by promoting quality green buildings. India has two main building environment assessment tools i.e. Indian Green Building Council (IGBC) and Green Rating for Integrated Habitat Assessment (GRIHA). The former is benchmarked with global standards while later is indigenously developed. This paper aims to focus on comparative study of IGBC (LEED India) and GRIHA rating system and compare both with regards to their certification-cost, influence and popularity, performance criteria and benchmarks (rating score). Through this study, an attempt is made to make clear understanding of IGBC and GRIHA rating system assessment criteria that need to be considered before certification.

The construction industry is having the highest rate of growth in the last 10-15 years, which causes a major negative impact on the natural resources available for construction and the environment in its consumption of energy. To resolve these problems, one needs to go for "Green Buildings". Today, there is a high level of demand for green or sustainable buildings. The most important decisions regarding a green building's features are made during the preconstruction and design stages. With the increase in demand for green buildings, the demand for Green Building Rating System (GBRS) is also increasing. Green Building Rating System (GBRS) set the benchmark for green building measurement, which helps to reduce the negative impact on the environment by promoting quality green buildings. Hence, it is considered as an attempt to check the status of green buildings growth in India. This paper includes the Objective, Methodology, Study process adopted for criteria of the Green Building Rating System (GBRS) to improve the performance of residential buildings in the Sangli and Kolhapur region and the expected conclusion. This research helps the builders to consider the criteria of the Green Building Rating System (GBRS) for residential buildings during the planning phase of the project. This will lead to the development of a sustainable world.

The main focus of this study is to outline the subtle distinct features in the "Energy" modules in green building grating systems i.e. Green Rating system for Integrated Habitat Assessment (GRIHA) and Indian Green Building Council (IGBC). For which we will start up with the building model being simulated in an energy simulation software/tool that are certified by competent authorities. The results as obtained from the simulation of the proposed building model will be used. Since, there are different benchmarks for allotting credits for achieving minimum energy efficiency such as Energy Performance Index (EPI) in GRIHA and percentage savings in energy consumption cost in case of IGBC. Keyword: GRIHA, IGBC, eQuest, Green Building I. INTRODUCTION Buildings are key to a sustainable future because their design, construction, operation, and the activities in buildings contribute significantly to high energy consumption-reducing energy demand in buildings can play a pivotal role in reducing energy consumption and solving challenges that lies ahead. Energy services in buildings-HVAC systems for thermal comfort, refrigeration needs, lighting systems installed, communication and entertainment (such as Television's, Laptop's, other accessories), as well as other amenities are majorly responsible for a significant share of energy use worldwide. Several energy-related problems affecting human health and productivity take place in buildings, due to poor indoor air quality or inadequate indoor temperatures. Hence, this issue must also be addressed to improve occupant's health and increase efficiency of people working inside these buildings. Reports includes that India's National Development Council is centered around the building sector based on energy conservation, vowing to make its Energy Conservation Building Code (ECBC) stricter, featuring its local building rating system GRIHA (Green Rating for Integrated Habitat Assessment), which is used for scaling the green building and energy efficient projects in the country. With rapid urbanization, as the quality of life improves, more and more people are being lifted above poverty line, and easy access to electricity. EIA projects that electricity's share in the total use of energy in buildings will nearly double in non-OCED countries, from 21% in 2018 to 38% in 2050 as compared to electricity's share of delivered energy consumption in OCED countries buildings will decrease from 24% to 21%. Kibert [1] through their research portrayed that Green buildings are built on the basis of ecological principles and the effective use of natural without compromising robust facilities. As per WGBC [2], Green building facilitates the preservation of precious natural resources and the improvement in the overall quality of life. The term Green Building can be easily understood in broader sense as the building or facility that consumes less amount of energy as compared to conventional buildings, reduces the dependency on energy supplied by grid, instead employs renewable energy sources, reduce their water demand through water harvesting and other techniques. The principle of "reduce, reuse and recycle" is relevant to green buildings. Zuo & Zhao [3] concluded that there is a need to evaluate the coverage of social and economic aspects of sustainability in green building rating and support the development of new ratings. Feng et al [4] Apart from short-term and long-term benefits that green building provides to its occupants, a green building needs to be economically rational. Analytical Hierarchical Process (AHP) is used to evaluate the relative significance among common components that contribute to sustainable buildings. Many rating systems that were studied were noticed to perform only a part of their originally intended objectives with energy efficiency taking the highest priority [5].
The building sector is the biggest consumer of electricity in India, also responsible for the largest chunk of CO2 emission& water consumptions 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 tones of waste from landfills [1]. The author of this paper has studied different rating systems available in India & the process of awarding the green building system & finally finds out which isthe most critical part of green building certification process. The idea is to understand the rating system & critical parts in certifications process so that we can have the detailed understanding of the selection process.
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.
Building construction is witnessing growth at highest rate in last 10 years in India. This has an impact on available resources of material for construction also direct and indirect effect on natural environment and increase in green house Gas emissions. Green building rating systems have been contributing to assess building performance based on their efforts to minimize this impact on natural environment. This study analyze the criteria and their significance in two basic green building rating systems in India LEED and GRIHA. This is a part of research study where an attempt is made to quantify the role of each criterion in both systems as performance indicator by post occupancy evaluation. In this paper, author performs comparative analysis of assessment criteria. Introduction: Construction sector in India is considered to be fastest growing construction sector in world. Built floor area is almost doubled in last ten years. This is driven by rapid urbanization. About 30% of India's 221.1 million households are now in urban areas with the urban population projected to more than double by 205012. Green house Gas emissions associated with Building Material manufacturing is also likely to impact on energy use patterns of occupants, increasing the need to consider lower embodied energy approaches to construction. Along with this attempts have been made to rate the type of construction based on its direct and indirect impact on environment by green building rating systems around the globe and by their Indian versions. There are prominently two rating systems working in India. Indian green Building Council (IGBC) and The Energy Resource Institute (TERI) are executing number of rating programs throughout India since 2001. The successful delivery of green buildings requires balancing energy and resource efficiency while providing a comfortable, healthy and productive environment. This requires careful selection of criteria to rate the performance of green building assessment mechanism. IGBC has initiated and continuously upgraded its own rating program since its inception. While GRIHA have achieved considerable footprint based on incentive programs released by government of India.
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.
