Unlock Bengaluru 2018: Roadmap to the Townships and Campuses of the Future

  1. 1. ROADMAP TO THE TOWNSHIPS AND CAMPUSES OF THE FUTURE Urban Design & Mobility | Energy | Water
  2. 2. AGENDA Source: *Mckinsey • Context • Challenges • Sectoral Solutions for Action • Panel 1- Roadmaps for Sustainability • Panel 2- Group Discussion and convening Lunch
  3. 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. 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. Image Data Source: Global Land Survey and LandSat (USGS), Open Streets Map, NHAI, BBMP, BDA 1990 2000 2010 2015 INCREASE IN URBAN FOOTPRINT OF BANGALORE (1990 TO 2015) CONTEXT
  5. 5. CONTEXT
  6. 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. 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. 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. 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. 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. -100 0 100 200 300 400 500 600 700 800 Annual Energy Demand Growth between 2013-2021 in BMAZ/BESCOM (Million KWhr) Commercial Industrial WaterSupply Hospitals & Education Domestic

  38. 38. Short Medium Long-term Disclosure of annual energy use for gated communities through crowdsourcing Research on Integrated Resources Management for gated communities 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. Working with BESCOM for benchmarking energy use for all consumers Utility-driven data disclosure on electricity consumption of individual households Preliminary/high-level scorecard for gated communities Utility-driven smart metering for all Engagement with KERC for advocacy around specific regulations for large sized gated communities e.g. mandatory X% generation from RE ACTIONS TO ACCELERATE CLEAN ENERGY

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
