Energy Scenario

• Most cities towns are experiencing big growth
  in peak electricity demand
• Heavy load shedding by Utilities to meet the
  demand.
• Diesel generators are used to meet demand during
  these periods.
• Installation of solar energy devices could be
  useful to reduce dependence on DGs in such
  situations.
• Various solar energy devices include solar water
  heaters, steam generating/ air heating systems,
  street lights/ garden lights, hoardings, traffic
  lights, power packs..
• Buildings/ housing complexes designed and
  constructed on concepts of solar architecture
  help in conserving significant amount of
  electricity.

Solar Water Heating Systems

• A well known commercially viable technology.
• Both FPC ETC based systems being installed in
  country
• Suited for installations in homes, hotels,
  hospitals, hotels, guest houses, institutions,
  dairies, industry various other establishments.
• A solar collector area of 180 million sq. m. has
  been installed worldwide, providing 9 billion
  liters of hot water per day. 60 of this is in
  China alone. Yearly installation in China is over
  10 million sq. m. per year
• In India, 2.45 million sq. m. installed so far.
• Estimated techno-economic potential is 40 million
  sq. m.

Solar Water Heating SystemsEnergy Savings

• A 100 lpd system can replace an electric geyser
  of 2kW capacity. On an average, it can save
  around 1200 units of electricity in homes or
  around 140 liters of diesel/ furnace oil in a
  year in industries commercial establishments
• Assuming that 50 of the domestic systems are in
  use at a time, 1 lakh systems installed in a
  city can result in 100 MW of peak load shaving
  
• 1 lakh systems can lead to electricity savings
  of 120 million units/yr to the users for a period
  of 15-20 years
• 40 million sq. m. potential could lead to peak
  load shaving of 14,000 MW ( 70 systems in homes)
  apart from saving of enormous amount of
  electricity fossil fuels in other
  establishments besides abating CO2 emissions in
  atmosphere

National Rating System for Green Buildings

• Building rating systems becoming popular for
  promotion of green buildings. In India, US based
  LEED in operation.
• A National Rating System - GRIHA developed in
  association with TERI
• Applicable to AC/ non-AC intermittent cooled
  buildings suitable for different zones of the
  country
• Developed modified through interactions with
  all stakeholders. Compatible with NBC 2005
  ECBC 2007
• System to help in assessing predicted
  performance of buildings over their entire life
  cycle
• Operates on 100 point marking system. 43 points
  pertain to energy waste management. Buildings
  to be star rated under Rating System

25
National Rating System for Green Buildings

• A Technical Advisory Committee formed to provide
  technical guidance on updation of GRIHA
• A National Advisory Council also formed for
  advice and direction to National Rating System
• System to be operationalized by GRIHA
  Secretariat and proposed to be incentivized by
  the Ministry
• Municipal Corporations/ Utilities to be requested
  to provide rebate in property tax/ electricity
  tariff or exempt stamp duty on star rated Green
  Buildings
• 5 million sq. m. of built area targeted during
