Development of Building Regulations and Guidelines to Achieve Energy Efficiency in Bangalore City Project supported by REEEP (Renewable Energy & Energy Efficiency Partnership) In Partnership with BDA & BBMP Presentation by TERI 10th June,2010

Background Globally, buildings account for :  40% energy use  42%water consumption  40% solid waste  50% raw material use  50% of air pollution  42% GHG emission  50% water pollution

 Total energy use in buildings is growing rapidly owing to economic development, increasing urbanization and improved lifestyles, predominantly due to increased space conditioning load.

The Present

•Construction sector contributes to 12% of India’s GDP and growing at 9.2% •Residential/commercial sector accounts for >30% of total electricity consumption •Domestic water consumption is 30 billion m3 and projected increase to 111 billion m3 by 2050 •Only 27% of waste water generated in urban India is treated •Construction industry generates 12 million tonnes of waste annually and 42 million metric tonnes (MMT) of solid waste is generated daily in the 3 urban areas of the country

The Need

4

Energy Scenario in Bangalore  Commercial and Industrial Buildings in Bangalore are highly energy intensive  90% of energy consumption in Bangalore is in Residential, Commercial & Industrial Sector  Energy Demand in 2008 – 1700MW  Annual supply to Bangalore city in 2008 – 9165 MU  Projected demand by 2020 – 3950MW  Projected supply by 2020 – 25000 MU

Current Practices in Bangalore Architecture Modern Architecture of Bangalore is influenced by Western Designs. Following are the existing architectural practices in Bangalore:  Majority of commercial and IT buildings are complete glazed structures.  Moderate climate of Bangalore city is not explored in the design.  Residential buildings are more climate responsive and naturally ventilated buildings.

Lighting Design Following are the existing practices in Bangalore:  CFLs and TFLs have replaced incandescent lamps.  Very few buildings adopt lighting controls such as occupancy sensors, dimmable ballast due to high initial cost.

Ventilation & Air conditioning Design Following are the existing practices in Bangalore:  Hybrid Air conditioning systems are coming up in Bangalore city because of Moderate climate.  Buildings do not install HVAC equipments that comply with ECBC efficiencies.

Existing Codes– Issues & Concerns 

Bangalore existing regulations (Revised Master Plan 2015)  Minimum aggregate area of openings is specified – is this enough to integrate daylight, ventilation, reduction in energy  There is no mention of external shading.  Setbacks, building height and FAR are emphasized.  Open space requirement between high rise buildings – is this enough.  Solar water heating is mandatory - are these followed?  Solar lighting in multi residential buildings is emphasized.



National Building Code – Is it followed in Bangalore?  Code includes guidelines for artificial lighting design, natural ventilation and air conditioning.



Energy Conservation Building Code – voluntary for commercial buildings – Is it followed in Bangalore?  Covers most important energy efficiency measures to be adopted in a building. 7

Making Building EE visible Building energy codes:

 moving from just prescriptive for heat transfer components to whole building energy consumption approaches  from residential to commercial  from new-build to also include retrofit

Appliance Standards and labels Energy performance certification

 From voluntary to mandatory  Enforced disclosure and labelling
