  • Once again, Energy Conservation Building codes consider manufacturing facilities as closed and airtight cells. But despite regulations, our factories keep breathing with the outside each time they give way to personnel, raw material and finished products. We can improve insulation, improve production equipments but our efforts are lost unless we keep protected our internal environment by efficient high speed doors. And the best way is to keep our doors closed the longest time possible with kinds of doors that really shorten the exposure time, http://www.nergeco.com e.g.
    A study carried out by an independent laboratory in July 2011, compared the energy savings which could be made by different automatic doors during an open/close cycle.
    This modelling of the reduction in exposure achieved by Nergeco's High Speed Doors over one cycle relative to another quick opening door comes out in favour of the Nergeco doors with an additional energy saving of 23 to 32 %!
    Their distributor in India, Bevcon : http://bevconzentry.com/HighSpeeddoors.html present a pretty smart approach of the potential savings depending on size and number of doors, climate objectives, and traffic flow.

    • The industrial sector is consuming 50% of total commercial energy in country.
    Commercial sources of energy
    • Coal and lignite contribute 56%
    • Oil and natural 40%
    • Hydroelectric power 3%
    • Nuclear power 1%
  • 5. Energy demand
    • Agriculture:3.5%
    • Industry:50.7%
    • Transport:23.2%
    • Residential:10.3%
    • Others:12.3%

  • 7. Barriers To Energy Efficiency
    • Lack of awareness
    • Lack of widespread education & training
    • Economic and market distortions
    • Lack of standardization & labeling on equipment/devices
    • Lack of financing
    • Lack of effective coordination
  • 8. Energy Conservation Act 2001
    • BEE operationalized from 1stMarch 2002
    • Standards & Labelling Program
    • Evolve minimum energy consumption and performance standards for notified equipment and appliances
    • Prohibit manufacture and sale of equipment & appliances not conforming to standards
    • Introduce mandatory labeling to enable consumers to make informed choices
    • Work started on Agricultural Pump sets, Distribution transformer, Motors, Lighting products and Refrigerators
  • 9. Energy Conservation Act 2001
    • List of Designated consumer
    • Designated consumers have to:
    • Get energy audit done by accredited energy audit firms
    • Implement cost effective recommendations
    • Appoint or designate energy manager
    • Comply with energy consumption norms and standards
    • By regulations BEE to prescribe
    • Qualification and certification procedure for energy manager and energy auditors
    • Accreditation procedure for Energy audit firms
  • 10. Energy Conservation Act 2001
    • Energy Conservation Building codes
    • To prepare guidelines on codes
    • To be modified by states to suit local climatic conditions
    • To be applicable to new buildings having connected load of 500 kW and above
    • To set up Energy Conservation Fund to provide
    • Awareness Creation
    • Innovative financing
    • Promotion of ESCOs
    • R&D, testing facilities and Demonstration projects

  • 14. PHILOSOPHY OF ENERGY AUDIT
    • Through energy audit, we optimize the consumption of fuel i.e. coal, electricity petroleum products etc.
    • To spread the benefits obtained through Energy Audit in any one industry to entire cluster
    • To replicate the benefit obtained through Energy Audit in other industries through Education Campaign and ITPs
    • Sponsor R &D projects identified from Energy Audit.
