  • 1. Energy Management- Working Towards Sustainable Future
    • Presentation by
    • Er.Arvind Dhingra
    • Certified Energy Manager BEEE-India
  • 2. World Energy Scenario
    • Total consumption of marketed energy is expected to expand by 54% from 404 quadrillion Btu in 2001 to 623 quadrillion Btu in 2025
    • World oil reserves are expected to last for 45 years and gas reserves for 65 years.
  • 3. Indian Scenario Absolute primary energy consumption is only 1/29 th of world, 1/7 th of USA, 1/1.6 th of Japan but 1.1 times that of Canada, 1.3 times that of France. 53% of the primary energy source available is coal.
  • 4. Available Options
    • Use of non conventional sources of energy
    • Energy Management
  • 5. What is Energy Management?
    • Judicious use of available energy resources to prolong their period of usage
    • Reduction of wastage of energy
  • 6. Why is Energy Management Required?
    • Available energy is scarce
    • Sources of energy are fast being used up
    • Energy costs
  • 7. How do we go about managing energy?
    • Reduce wastage
    • Save Energy
  • 8.
    • Why Save Energy?
    • Financial Benefits
    • Legal
    • Environmental
  • 9. Where can energy management be applied?
    •     Factories
    •     Warehouses
    •     Retail outlets
    •      Mixed use sites
    •      Schools, colleges & universities
    •      Public buildings
  • 10.
    • How can we manage energy ?
    • Establish energy Management cells
    • Small Group activities
    • Monitoring
  • 11. Approaches to Energy Management
    • Automatic meter monitoring
    • Monitoring and targeting
    • Conducting proper energy audits
    • Improve the efficiency of the process
  • 12. Energy Management
    • One area where energy management can be applied and lot of energy saved is the commercial office buildings. Based on this the BEEE has devised an ECBC code- Energy Conservation Building Code
  • 13. Growth Profile of Indian Commercial Sector
    • Demand for OFFICE SPACE in India is driven by the increasing share of the services sector in the Indian economy
    • Office space supply shifting from Central Business Districts to secondary centers (office and IT parks)
  • 14.
    • Modern office buildings in newly developed areas enable the higher
    • quality standards that are essential for IT services
    • All India office market
    • • 70% by IT Services companies (more than 7000 No.) in India
    • • 15% by financial service providers & pharmaceutical sector
    • • 15% by other sectors
  • 15.
    • • Office stock must increase nearly 20 million /year in New Delhi, Mumbai, Bangalore to keep pace with growing demand
    • • Conservative estimate (for India): Approx. 55 million /year
    • SHOPPING CENTRES/MALLS
    • By the end of 2008, space of 79 million sf in 257 centers are estimated in 15 largest cities of India
  • 16. Energy IN-efficiency is rampant
    • Most commercial buildings have energy performance index (EPI) of 200 to 400 kWh/sq m/year
    • Similar buildings in North America and Europe have EPI of less than 150 kWh/sq m/year
  • 17.
    • Energy-conscious building design has been shown to reduce EPI to 100 to 150 kWh/sq m/year in India – development of such buildings is restricted to environmentally-sensitive corporates
    • Large scale energy-efficient building design is limited due to split incentives - builders fear that they would bear the costs, while tents would enjoy benefits
  • 18. Electricity Use in the Commercial Sector is exploding
  • 19. What are Energy Conservation Building Codes?
    • ECBC set minimum energy efficiency standards for design and construction
    • ECBC encourage energy efficient design or retrofit of buildings so that It does not constrain the building function, comfort,
    • health, or the productivity of the occupants
    • Lifecycle costs (construction + energy costs) are minimized
  • 20.
    • ECBC covering the following components prepared:
    • Building Envelope (Walls, Roofs, Windows)
    • Lighting (Indoor and Outdoor)
    • Heating Ventilation and Air Conditioning (HVAC) System
    • Solar Hot Water Heating
    • Electrical Systems
  • 21.
    • ECBC finalized after extensive consultation
    • Voluntary introduction of ECBC in May 2007; mandatory after capacity building and implementation experience
    • Impact of ECBC - Reduced Energy Use for buildings
    • National Benchmark ~ 180 kWh/m2/year
    • ECBC Compliant building ~ 110 kWh/m2/year
  • 22. EEMs at Rashtrapati Bhawan
    • Energy Saving Electricity savings Savings in lakh
    • Measure (kWh/ year) Rupees per year
    • Air conditioning 5,54,266 35.3
    • Lighting 3,25,028 20.7
    • Pumping 54,140 3.45
    • Total 9,33,434 59.45
  • 23. SCHEME FOR RATING OF BUILDINGS
    • The Star Rating Program for buildings is based on actual performance of the building in terms of specific energy usage (kWh/sq m/year).
    • This programme would rate office buildings on a 1-5 Star scale with 5 Star labeled buildings being the most efficient.
    • Five categories of buildings - office buildings, hotels, hospitals, retail malls, and IT Parks in five climate zones in the country have been identified
  • 24.
    • Office buildings in the following 3 climatic zones for airconditioned and non- air-conditioned:
    • • Warm and Humid
    • • Composite
    • • Hot and Dry
    • It will be subsequently extended to other climatic zones and building types
  • 25. Sample Labels Refrigerator Tubular Fluorescent lamp

  • 27. What is Star Rating?
    • Energy Star is an international standard for energy efficient consumer products. It was first created as a United States government program in 1992, but Australia, Canada, Japan, New Zealand, Taiwan and the European Union have also adopted the program
  • 28. What is Star Rating?
    • Star rating is a system initiated by BEE (Bureau of Energy Efficiency) to determine the energy efficiency of an appliance, like air-conditioners. Depending on their energy efficiency they are rated on a scale of 1 - 5 stars. Higher the number of stars, better is their energy efficiency.
  • 29.
    • The star rating system is a way of measuring energy efficiency. It’s applied to all electronic products such as Refrigerators, TVs , ACs and so on. Every AC model can get its EER tested and get a star rating. Currently, it’s voluntary, not mandatory for companies to get a star rating for their models.
  • 30. How is Star Rating Calculated
    • For example in case of AC’s
    • Calculate EER by following method: BTU/(3.41* power input) and then from the table get the star rating.
  • 31. Some terms for Star Rating
    • Projected Annual Energy Consumption
    • Here the tested Energy consumption of each unit is measured and calculations for annual energy consumption are made as
    • PAEC= Et*365/1000
    • Where Et is the tested energy consumption in Wh per 24 hrs rounded to nearest whole number
  • 32. Calculation of Star Rating
    • The star rating is calculated using the formula:
    • Star Rating Band = Knf*V adj*Cnf
    • Knf is constant mutliplier (kWh/litre/year)
    • V adj is total adjusted volume for frost free
    • Cnf is constant fixed allowance (kWh/year)
  • 33. Calculation of Star Rating
    • Star rating band valid upto December 2011
            • Knf Cnf
    • 1 star * 0.5578 486
    • 2 star ** 0.4463 389
    • 3 star*** 0.3570 311
    • 4 star**** 0.2856 249
    • 5 star ***** 0.2285 199
