Abstract: The rapid rate of urbanization has led to the vast expansion of grey infrastructure in
the National Capital Territory of Delhi. This dominance of grey infrastructure resulted in microclimatic changes such as urban heat island (UHI) effect and intensification of heatwave
effectivity during the summer season in the NCT of Delhi. The series of micro-climatic changes
compelled the policy makers to adopt the Leadership in Energy and Environmental Design(LEED) certification for all the Greenfield projects and grey field projects. The LEED certification
promotes the “green” opportunities for reducing the negative impact the building has on theenvironment. The opportunities range from preventing erosion of topsoil, water contaminationand creation of heat islands, effective use of a barren or wastelands etc. Most importantly,
LEED uses what nature has given us by working with existing topography, plants and views.
LEED focus on efficient urban design, use of renewable energy, deliberate mechanical andelectrical system selection and proper commissioning and monitoring. Moreover, it also keeps
the concept of ‘Environmental Footprint’ or ‘Life Cycle Assessment’ at the core while carryingout the work of Urban Design. The present research study begins with the assessment of the
expansion of urban built-up during the period 1990-2015 in the NCT of Delhi. It is followed by
the critical analysis of the need for LEED certification in the NCT of Delhi. Further, the study
identifies the descriptive details like objectives, principles, aspects and other prospects of LEED
certification. Lastly, the present research study carries out the critical analysis of major projects
completed by LEED players so far. The study also depicts the role of LEED certification in thecontext of micro-climatic changes in the NCT of Delhi.
Key words: Micro-climatic Changes, Urban, Environmental Footprint, Green Opportunities
Introduction
The landscape of NCT of Delhi has undergone drastic changes from a rural area to an urban
area due to rapid rate of urbanization. As per the Census of India, the urban area has increased
from 46.21 percent (1991) to 75.09 percent (2011) while the rural area decreased from 53.79
percent (1991) to 24.91 percent (2011).Consequently, Urban Built Environment undergone
expansion and is dominated by cultural features like Multi-storey Buildings (both Commercial
and Industrial), Malls, Real Estate Township, Multi-Level Parking, Broad Roads, flyovers, Metro
Rail with reduced ‘Urban Open Spaces’. The increased urban area and the nature of Urban
Built Environment in the NCT of Delhi has resulted in micro-climatic changes like Urban Heat
Island Effect and the intensification of Heatwaves during the summer season. The policy
planners, worried by these micro-climatic changes in the NCT of Delhi and other regions ofIndia, set up Leadership in Energy and Environmental Design (LEED) certification in India from
1st January 2007. It is an effort to develop cities on the current lines of sustainability through thedevelopment of sustainable urban neighbourhood. LEED is a sustainability assessment tool
which regulates the sustainable approaches in urban design and urban planning. The
integration of environmental, social and economic aspects is at the core of sustainability andpopularly known as the ‘Circle of Sustainability’. This is widely used in cities and urban
settlements by a series of global organizations and it helps to improve the misunderstanding ofsustainable urban design, which balances the social and economic effects of the built
environment, while mitigating the environmental impacts. In the interpretation of sustainability,
environmental concerns often gain more attention than social or economic factors. For
comprehensive sustainability assessment purposes, there is a need for a means to ensure81

adequate attention to all important factors. The sustainability assessment framework, based on
the circle of sustainability, interrelate the economic, social and environmental dimensions.
Objectives of the Study
The objectives of the research study are as follows: To assess the expansion of Urban Built-Up during the period 1990-2015 in the NCT of
Delhi.
 To carry out the Critical analysis of need for LEED certification in India.
 To discuss the details (objectives, principles etc.) of Leadership in Energy andEnvironmental Design (LEED) certification.
Database and Methodology
To assess the expansion of urban built-up, the land use and land cover of the NCT of Delhi was
carried out from satellite data of Landsat – 4,5 [Thematic Mapper (TM)], Landsat – 7 [Enhanced
Thematic Mapper (ETM+)] and Landsat – 8 [Operational Land Imager (OLI) – Thermal Infrared

Sensors (TIRS)] for the three different time periods 1990, 2000 and 2015 (Table 1).

Expansion of Built-Up During the Period 1990-2015
During the period 1990-2015, landscape of Delhi has been altered at a rapid rate.
Consequently, the dominance of built-up in the Delhi is major characteristic feature of the landtransformation during the above-mentioned period. The built-up through its expansion
encroached the land area of other categories of land use and land cover viz. water bodies,vegetation, cropland, fallow land, riverbed. In other words, the shrinkage effect of othercategories was balanced by the expansion of the built-up. During the period 1990-2000 (table 1& figure 2), the land use/land cover category which suffered major loss of land to built-up was
fallow land and is depicted by purple colour in Figure 2. The prevalence of purple colour can beseen throughout the image and reflects the land transformation from fallow land to built-up. It
can be inferred from the image that the peripheral region of NCT of Delhi experienced the
maximum land transformation from fallow land to built-up. The second category of Land
Use/Land Cover which experienced comparatively major land transformation to built-up was
Crop Land and is depicted by the violet colour in Figure 2. The dominance of violet colour canbe seen in the south-west region and reflects that cropland in this region experienced landtransformation to built-up at considerable level. The third category is of vegetation whichsuffered a huge loss during the period 1990-2000. The land transformation under this category
is depicted by the red colour on the image. The dominance of red colour can be seen in thenorth region, north-east region and south-east region and this shows that vegetation category
has been degraded and transformed to built-up category. The last two categories of LULC thatis waterbed and riverbed experienced marginal land transformation and are depicted by theyellow and brown colour respectively. During the period 2000-2015 (table 1 & figure 2), themajor category of land use/land cover which experienced large scale land transformation wasvegetation and land transformation of this category is depicted by the red colour in Figure 2.
The careful observation shows that red colour is dominant in the central region, north region,
north east region, east region, and south- east region and it can be inferred that in the abovementioned regions experienced the loss of vegetation cover and expansion of built-up during
the period 2000-2015. The second category of LULC which experienced comparatively hugeland transformation is of Cropland and the dominance of violet colour in west region and northwest region shows that crop land got transformed to built-up in these regions. The othercategories of Fallow land, water bodies and riverbed experienced marginal land transformation
during the period 2000-2015.

Rate of Change’ of Various Categories to Built-Up during 1990-2015
The ‘Rate of Change’ of land for the category of built-up was +939.132 during the period 19902015 (Table 3 and Figure 3). The built-up area increased to 10,922.2 hectares and 12,556.1
hectares during the period 1990-2000 and 2000-2015 respectively. On a whole, there was an83increase of 23,478.3 hectares of land area under the category of built-up during the period
1990-2015 in Delhi. Among categories of LULC, vegetation with highest ‘Rate of Change’ thatis -537.72 faced large scale loss of land followed by the fallow land (-226.916), cropland(157.364), water body (-12.636) and riverbed (-4.5). The shrinking effect of the above
categories of land use/land cover is equalized by the expansion of built-up in Delhi. The fact
can be proved by summing up all the negative values of ‘Rate of Change’ and comparing theresultant value with the positive value of ‘Rate of Change’ of built-up.

Built-UpWhat is the Need of LEED Certification in India?
Over-expansion of grey infrastructure due to urbanization has induced micro-climatic changes
in the form of Urban Heat Island (UHI) effect in the NCT of Delhi. The UHI effect results inthermal discomfort (both indoor and outdoor) and increased energy consumption in airconditioned buildings. It is estimated that 3 percent to 8 percent higher electricity demand incities with populations greater than 1,00,000 is used to comfort the heat due to the heat islandeffect (Green in Practice, 103 – Cool Communities, 2012).
The solar energy in the form of solar radiations falls on the surface of cultural features
like buildings, roads. The part of this incoming solar radiation is reflected into space as solarreflectance of the surfaces due to reflectivity while the remaining part of solar radiation isabsorbed and results in heating of cultural features and on heating, cultural features emit infrared radiations due to emissivity. During this process, air temperature is increased due toabsorption of solar radiation by the atmosphere and the heat emitted by different surfaces while
surface temperature is increased due to solar radiation and the solar reflectance of thesurfaces. Surface Temperature plays a major role in the Urban Heat Island (UHI) effectbecause of hot surfaces of the cultural features emit heat in the surroundings which in turnincreases the air temperature and thus, making surroundings much warm as compared to therural counterpart. Urban Heat Island (UHI) effect is the result of a combination of several factors
like more heat-absorbing surfaces (Rooftops, Buildings and Paved Surfaces), the trapping of
hot air between buildings, limited tree cover and other heat-trapping and heat-inducing factors
such as fuel combustion and air conditioning can result in average annual temperatures inurban areas being 1-3°C hotter than surrounding areas. This Urban Heat Island (UHI) effect isobserved during night in the summer season in the NCT of Delhi. Urban Heat Island (UHI)
effect intensifies the heatwaves during summer in the urban areas and consequently, residents
are exposed to higher temperatures during the day as well as night.
The higher urban temperature means i) greater energy use during the summer, ii)
Increased air pollution and Green House Gas emissions, iii) Negative effects of higher
temperatures on human health and comfort and iv) warmer storm water run-off affecting water
quality. If all buildings in urban areas were made to adopt green Building concepts, India could
have saved more than 8400 MW of power which is enough to light half of Delhi or 5.5 lakhhomes a year per estimates by TERI. A green building depletes very little of the natural
resources during its construction and operation. The aim of a green building design is tominimize the demand on non-renewable resources and maximize the utilization efficiency ofthese resources when in use and utilization of renewable resources.
The green building rating system is an evaluation tool that measures the environmental
performance of a building through its life cycle. Building rating systems are a popular tool tobring momentum in achieving energy efficiency and sustainability in buildings. In India, atpresent, there are predominantly two rating systems to certify buildings as green buildings,
namely LEED. This rating system has a predefined set of criteria and there are points for eachone of these criteria. The buildings are required to fulfil the defined criteria and achieve acertain number of points to be certified.
Important Criterions under LEED – India
The important criterions under the LEED-India Green Building Certification System (table4)include i) Sustainable Sites, ii) Water Efficiency, iii) Energy and Atmosphere, iv) Materials andResources, v) Indoor Environmental Quality and vi) Innovations and Design Process.

Soil erosion and sedimentation control are the pre-requisite which should be taken into
consideration before selecting the Sustainable Site. The intention is to minimize impact onwater quality and air quality (Table 4).The selection of ‘Sustainable Sites’ is based on the basic
principle which states that time and nature have sculpted the land. In other words, we aresupposed to develop within the existing topography, plants and views despite digging andlevelling of land, clearing of forest and alteration of views. The sustainable sites section of
LEED – India outlines various ‘Green Opportunities’ for reducing the negative impact thebuilding has on the environment. The opportunities range from preventing erosion of topsoil,
water contamination and creation of heat islands, effective use of a barren or wastelands etc.

‘Water Efficiency’ can be defined as the accomplishment of a function, task, process, or
result with the minimal amount of water feasible (Table 6). It is an indicator of the relationshipbetween the amount of water required for a purpose and the amount of water used ordelivered. Water efficiency differs from water conservation in that it focuses on reducing waste.
A proposition is that the key for efficiency is reducing waste not restricting use. It alsoemphasizes that influence consumers can have in water efficiency by making small behaviouralchanges to reduce water- wastage and by choosing more water-efficient products. Examples ofwater-efficient steps include simple measures like fixing leaking taps.

The ‘Materials and Resources’ are in the picture from the first round of planning to thefinal stages of demolition or renovation of a building or product (table 8). Of all the criteria
86covered by LEED – India, Materials and Resources has perhaps the broadest application andrelevance. They are the ingredients and choosing them wisely makes all the difference in termsof the overall impact of the building throughout its life. This is where ‘Environmental Footprint’or ‘Life Cycle Assessment’ comes into play. The study shows that 40 percent of the Carbon
Dioxide that contributes to our warming planet comes from buildings. While some of it is asecondary effect of operational needs such as electricity, air-conditioners and heating, many
Green House Gases (GHG’s) arise from resource extraction, manufacturing and production of
the building materials themselves.

Note: *R = Required‘Indoor Environmental Quality’ (IEQ) addresses the subtle issues that influence, how wefeel in a space (Table 9). Building green means considering not only the environmental impact
of materials and construction but also the physical and psychological health of the occupants.
Some can argue that it is not desirable, but also a fundamental human right to live and work inspaces with healthy indoor environments. Buildings enhance people’s lives when they permit
ample air circulation, maintain clean air and comfortable temperatures, and allow individuals tohave a sense of control over their own indoor experience.

Certification Levels of LEED in India
LEED is used as a design guideline and third-party certification tool; it aims to improve
occupant well-being, environmental performance and economic returns of buildings using
established and innovative practices, standards and technologies. LEED is like a checklist of
credits that can be achieved in the above discussed major categories. LEED evaluates abuilding for sustainability objectives it achieves and recognizes building at four certification level(table 11). LEED is one of the most successful green building rating systems in the world
because of its early market penetration and adoption by professionals. This rating system is87based on accepted energy and environmental principles and strikes a balance between known
established practices and emerging concepts. It is performance-oriented, wherein credits areearned for satisfying criteria addressing specific environmental impacts inherent in the designand construction. Different levels of green building certification are awarded based on the total
credits earned. The system is designed to be comprehensive in scope, yet simple inapplication. The specific credits in the rating system provide guidelines for the design andconstruction of buildings of all sizes in both the public and private sectors.

Conclusion
LEED promotes rainwater harvesting, solar Photo-Voltaic (PV) installation, construction waste
management, energy efficiency and several other techniques which minimize the impact ofgrey infrastructure on micro-climate of a region. The NCT of Delhi is already facing the problem
of Urban Heat Island effect and the intensification of heatwave effectivity during the summer
season and therefore, if followed properly then LEED certification will resolve the problem of
micro-climatic changes to a greater extent in the NCT of Delhi. LEED certification is applicable
on Greenfield projects, grey field projects, brown field projects and so, LEED certification must
be made mandatory for all projects whether private or public.
