Considering the GRIHA rating into smart city

1. SMART CITY RATING DEVELOPMENT FOR GREEN RATING FOR INTEGRATED
HABITAT ASSESSMENT (GRIHA) RATING
Broad functions of a building should provide visual and thermal comfort, and which can be
provided by naturally and artificially, which ultimately leads to local and global conditions. The
cost of very high energy consumption will provide ‘international’ comfort conditions in
buildings. A building needs to consume resources for construction and operation.
In the Indian context, a building is 'green' when
 It is designed using an integrated approach (as mentioned in NBC, Part 0)
 It provides its users with an “optimal” level of comfort catering to local needs (as per
NBC-Part 8)
 It uses minimum resources, sourced locally (as per various IS codes and other local
materials)  It consumes minimum energy and water (as per ECBC and NBC)
 It generates optimum waste, processed locally (as per CPCB, and MoEF norms)
... during its construction, operation and demolition (i.e., over its entire life cycle).
Sustainability is ALWAYS local context.
GRIHA attempts to minimize a building’s resource consumption, waste generation, and overall
ecological/ environmental impact by comparing them to certain nationally acceptable limits /
benchmarks. It does so, adopting the five ‘R’ philosophy of sustainable development, namely
Refuse, Reduce, Reuse, Recycle, Reinvent.
GRIHA attempts to quantify aspects, such as:
 Energy / power consumption (in terms of electricity consumed in kWh per square meter
per year)
 Water consumption (in terms of litres per person per day)
 Waste generation (in terms of kilograms per day, or litres per day)
 Renewable energy integration (in terms of kW of connected load)
GRIHA assesses a building out of 34 criteria and awards points on a scale of 100. In order to
qualify for GRIHA certification, a project must achieve at least 50 points.
Importance of Green Building in Smart city
 Reduced energy, water consumption and investment
 Reduced destruction of natural areas, habitats, biodiversity, reduced soil loss from
erosion etc.
 Reduced pollution loads and Increased user productivity

2. GRIHA helps in recognizing development that meets certain environmental and sustainable
development practices.
The basic idea behind the green building is to carve out fine techniques and skills to bring down
the effect on the environment and human health to a lesser degree and by promoting the optimal
use of renewable resources
SMART CITY
A smart city uses information, communication and technology to enhance its livability,
workability and sustainability. A smart city is build-up by three key basic functions: Information
collection, communicating, and crunching (analyzing).
Smart Cities Mission envisions developing 100 cities in the country as model areas based on an
area development plan and making citizen friendly and sustainable
"100 Smart Cities Mission" was launched on 25 June 2015. A total of ₹98,000 crore has been
approved by the Indian Cabinet for the development of 100 smart cities and the rejuvenation of
500 others.
The smart city concept is not without challenges, especially in India. For instance, the success of
such a city depends on residents, entrepreneurs and visitors becoming actively involved in
energy saving and implementation of new technologies. Residential, commercial and public
spaces to make sustainable by ways of technological advancement, but a high percentage of the
energy consumption is still in the hands of end users and their behavior.
Ecological impacts should be given paramount consideration, more so when resources are
nonrenewable or where the result is irreversible.
Due to rapid urbanization, there is an increased pressure on urban infrastructure leading to
exploitation of urban environment.
India is, at present, experiencing rapid construction activities in all spheres, which, in turn, is
leading to an increase in the demand for energy. It is due to rapidly growing urbanization and the
increasing affordability of the people. Buildings are the major consumers of energy in their
construction, operation and maintenance.
In case of redevelopment and Greenfield models of smart cities at least 80% buildings should be
energy-efficient and green buildings. Additional 15% consideration have to provide for 15% in
the affordable housing category in Greenfield development.
GRIHA rating is capable enough to strike a balance between development and environment.
