3. CONTEXT
• 700-900 million Sq. mts of residential
and commercial space to be built every
year –
one Chicago every year!*
• High and growing private investment in
the real estate sector, an industry
nationally responsible for 7% of GDP.
• Massive private sector engagement
needed to construct new building stock.

4. • 466% increase in the built up area
of Bengaluru from 1973 to 2000.
• As per 2014 data over 5,000 acres
of Bengaluru was under
development in the periphery,
designed to be car dependent,
relying on diesel-fueled power and
would survive on purchased water.

INCREASE IN URBAN FOOTPRINT OF BANGALORE (1990 TO 2015)
CONTEXT
6. • Unsustainable forms of urban development, including large,
sprawling “gated communities”.
• High real estate with cheaper land on urban periphery.
• No government oversight or regulation, no requirement for
supporting infrastructure; private provision is the norm.
• Location and price still key determinants in real estate,
low market demand for green housing, lack of consumer awareness,
and principal-agent problem in residential sector.
CHALLENGES
8. Figure 1 – Bangalore’s Piped Water Access
• 70% of water demand met by
Cauvery- 100 km away, pumped
uphill to height of 540m.
• BWSSB network coverage not
uniformly extended to periphery.
• Disproportionate dependence on
ground water (extraction>rainfall),
tanker water.
WATER SCENARIO Maximum access
Least access
9. SANITATION SCENARIO
• Gated communities often
without access to sewage
networks.
• Use of small-scale STPs
hampered by power outage,
high cost of backup power.
• Desludging vehicles dump
waste in adhoc manner.
• Lack of coordination
between agencies.
Figure 2 – Sewerage Network of Bengaluru
10. ENERGY CONSUMPTION
SCENARIO
• Bengaluru consumes 35% of
Karnataka’s power- residential sector
makes up 26% of power sales.
• Little research and data on energy
use within gated communities
particularly for common area
amenities.
• No existing policies for improving
efficiency of existing buildings.
11. ELECTRICITY
• Domestic Consumption will
increase from 8,000 to 13,500
MKWh between 2013 to 2031.
• Percapita consumption will
almost double from 880 to 1,500
KWh.
• 1.67 billion sq.ft of roof top
space.
• 50% of this space generate 8450
KWh.
• Even 20% generates 3400 KWh.

14. • Safety concerns while
travelling
to and from development
• Poor road and pedestrian
networks
• Lack of services
• Poor access to public transport
• Car-centric lifestyle
• Availability of open spaces and
parks
• Distributed services and
facilities
• Green practices
• Safety within the premise
CHALLENGES OPPORTUNITIES
15. Policy and
regulations
Development control regulations not supportive of compact and connected developments
No disincentive to build in peripheral areas despite service delivery issues
Implementation Lack of technical capacity to implement/ upgrade to sustainable solutions; security concerns
Capacity Lack of motivation and capacity of for monitoring, service provision and operations

22. • Increasing water stress leading to innovation in water efficiency,
reuse and demand management practices
• Switch from linear supply and service delivery models to circular practices
to optimize resource use
• Improve implementation of RWH and aquifer recharge systems

Mandatory disclosure of annual energy
use for gated communities, once every 2
years
Creating tool/platform for
monitoring energy use at gated
community level
Generating recommendations
and priorities from data
collected through the tool
Zoning regulations to encourage RE
generation. These changes must be
brought in gradually and involving all
stakeholders.

39. TOWARDS A SUSTAINABLY MANAGED WATER /
WASTEWATER SECTOR
Short-term Medium-term Long-term
Communication of good practices on
visible platforms
Layout plans developed by architects and
builders for municipal approval to include
water plan.
Generate metrics for assessing good
practices and development of platform for
peer learning and sharing of good
practices in the water-wastewater sector.
Focus on big conversation items such as
Day Zero for Bangalore to bring about
awareness on the water stress and risks
faced by communities
Mapping and modelling at city scale
(includes water audits), aquifer status etc.,
catchment zones.
Enforcement of a transparent monitoring
system
Water awareness for end users/
consumers to assess systems provided by
developers and capacity to manage
recurring O&M issues
Identifying micro watersheds allows for
the possibility of development of common
pool activities (such as community aquifer
management; aggregation of wastewater
streams for management at scale.
Sharing roadmap of stakeholder with
concerned stakeholders such as BAF, other
apartment associations and RWAs
40. Short Medium Long-term
Buses, new mobility solutions to
aid last mile connectivity (Eg:
Metrobikes)
Government to pilot an
initiative to showcase better
mobility practices ( Eg:
Partnering with CREDAI)
Master plan and Development Control
regulations to promote compact and
connected developments
Opening data availability
technology-based applications (Eg:
BMTC, BBMP data)
RWAs can take over a road for
maintenance once data is
accessible
Increase the cost of personal vehicle
ownership
Integrate the ticketing system for
different transport modes
Greater responsibility between
communities for shared
amenities (Eg: public spaces)
