Indian context

Urbanization Number of large cities to increase Energy security : fuel import dependency, coal

dependency increasing Energy shortages already, low per capita energy

consumption; environmental considerations Sustainable habitats Integrated planning esp. for cities Self-sufficient neighborhood

Elements of Sustainable Habitat

Optimal allocation of land

Built Environment

Buildings Surroundings

Efficient appliances and fixtures

Choice of materials

Location of BuildingSmart Buildings (bldgs. as generators of energy)

Transport systems and infrastructureEnvironmental management - Water & waste

Energy security – renewable sources and energy efficiency

Elements contributing to sustainable

habitat

Density: It is the concentration of population, dwelling units, employment or any other variable over a specific area which can be either gross or net

Design: the street network which is pedestrian oriented rather than auto and whose characteristics include side walk, inter connection with in the streets, number of intersection, pedestrian crossing, street lighting

Diversity: It is a measure of variety of land uses present in a given area on the basis of floor area, employment and land area

Distance to transit: the average of the shortest street routes from home or work to the nearest rail stations and bus stops

Destination accessibility: the ease with which one can access the trip attraction to both local (market) and regional (jobs) destinations

Building lighting(Day lighting &Artificial lighting)

Building space conditioning

Equipment (Transformer/pumps/motors etc.)

• Day lighting integration in design

• Natural ventilation / thermal comfort

• Efficient building envelop design

• Efficient indoor and external lighting fixtures

• Automatic controls• Efficient HVAC systems• Equipment to meet ECBC

standards

Energy generation from RE energy

• Solar• Wind• Bio Gas• Geo thermal

• Efficient management of energy and water resources

• Management of material resources and waste • Restoration and protection of environmental

quality • Enhancement and protection of health and indoor

environmental quality • Reinforcement of natural systems • Analysis of the life cycle costs and benefits of

materials and methods • Integration of the design decision-making process

CHARACTERISTICS OF GREEN AND

SUSTAINABLE BUILDINGS

GRIHA-Green Rating for Integrated Habitat

Assessment

Tool to facilitate design, construction, operation of a green building ,and in turn ….measure “greenness” of a building in India

What gets measured gets managed

GRIHA RATING SYSTEM

Set of 34 criteria100 (+4 innovation points) Point system with differential weight age on various Criteria50-6061-7071-8081-9091-100

KEY HIGHLIGHTS OF GRIHA

•Sets out guidelines for design, construction and operation•Combination of qualitative and quantitative criteria•Sets performances benchmarks for key resources like, energyand water•Facilitates integration of traditional knowledge on architecturewith present day technology•Integrates all relevant Indian codes and standards(e.g Nationalbuilding code 2005, Energy Conservation Building Code 2007,IS codes)•Is in complete alignment with government policies andprograms (e.g Environmental clearance by the MoEF)

WASTE MANAGEMENT

HEALTH &WELL BEING

Can you design a green building?1.By adopting the integrated design approach such that the client, architect,engineers, and consultants design the building in a coordinated manner with acommon goal – sustainability.2.By following regional development plans (such as the UDPFI guidelines, masterplans) and local building by-laws3.By following India’s national codes and standards4.By optimizing site conditions (trees, water bodies, wind-flow, orientation, etc.) andharnessing them to cater to the thermal / visual comfort requirements of thebuilding5.By adopting sound architectural practices and taking examples from India’straditional architecture6.By adopting locally available construction materials and giving impetus to localarts, crafts, architecture and artisans7.By designing precisely-sized energy systems and not basing them on broadthumb-rules8.By reducing the resource consumption of the building and its inhabitants so thatthe waste generating there-from is reduced9.By adopting energy efficient technologies (EETs) and equipment10.By adopting renewable energy technology (RETs) applications to reduce thedemand on conventional energy
