  • 1. LOGO Energy Efficiency in Buildings in Argentina Gautam Dutt MGM Innova CIB webinar - Latin America – November 4, 2010 Implementation of Energy Efficient Policies in Buildings in 5 continents
  • 2. Residential (22%)LOGO Commercial & public buildings (7%) = 29% of total energy use (2004). Residential energy use• Mostly electricity and natural gas• Electricity use has relatively little seasonal variation (mostly refrigeration and lighting)• Natural gas consumption is highly seasonal Source: Energy Secretariat, 2010
  • 3. Residential electricity use• Major end uses • Refrigerators and freezers • Lighting • Video appliances • Standby • Air conditioning• In recent years • Energy consumption of some end uses have changed drastically: end-use breakdown not known • Per capita electricity use stable 1999-2007, and decreased recently: refrigerators and lighting…
  • 4. Refrigerator testing and labelingStandard or Year DescriptionResolutionIRAM 2404-1 1997 Measurement of energy consumptionIRAM 2404-2 2000 Measurement of noiseIRAM 2404-3 1998 Label designSICyM 319 1999 Mandatory labeling requirement (initial)SCT 35 2005 Mandatory labeling (finally in place)
  • 5. Refrigerator and freezer labeling • Refrigerator label is identical in design and values to the EU label • Finally put into place in 5/2005 (fridges) • Spectacular impact, already by 7/2007: 50% Julio - Todos Modelos 45% Pre-Resolución 40% 35% Distribución (%) 30% 25% 20% 15% 10% 5% 0% A B C D E F G Clases de eficiencia Source: AES, 2008
  • 6. Sales of compact fluorescent lamps Year Imports CFL price (millions) (US$) GEF project: 2000 3.0 15Efficient Lighting 2001 7.6 12 Initiative (ELI) 2002 2.0 3.4-7.5 2003 7.7 3.3 2004 13.9 3.3 2005 13.0 3.3 2006 14.9 3.3 Source: AES, 2008
  • 7. Residential lighting energy useGovernment programs:2008-09: Distribute 2 CFLs per household to all householdsJan. 2011: Prohibition of sales of most incandescent lamps Baseline versus efficient lighting program scenarios Source: Energy Secretariat, 2010
  • 8. Labeling extended to lampsStandard or Year DescriptionResolutionIRAM 62404-1 2005 Incandescent lampsIRAM 62404-2 2006 Fluorescent lampsSICyM 319 1999 Mandatory labeling requirement (initial)SCT 86 2007 Mandatory labeling (finally in place)Label not so useful:• Incandescents are all E,F,G.• Fluorescents and CFLs are all A or B• Energy efficiency rating letter does not consider the useful life of lamp• Most people do not know what label means
  • 9. Air conditioners (2007) Split Com pacto 30 12Cantidad de m odelos 25 Cantidad de modelos 10 20 8 15 6 10 4 5 2 0 0 A B C D E F G A B C D E F G Clases de eficiencia Clases de eficiencia Source: AES, 2008 (Data from catalogs)
  • 10. Space heating is over 60%LOGO of total natural gas consumption Source: Energy Secretariat, 2010
  • 11. Base-load natural gas useLOGO Item Use m3/day Cooking 0.5 Water heating use 0.6 Pilot (water heater) 0.5 Total 1.6 Under study: Eliminate pilot from instant water heaters Source: Energy Secretariat, 2010
  • 12. Other labels under development Gas cook stoves IRAM 19050-1 Similar to Brazilian label Original IRAM design Thermal envelope IRAM 11900
  • 13. Exec. Order 140 (2007) National Program for the Rational and Efficient Use of EnergyKey elements (for building energy efficiency) Replace incandescent lamps by CFLs Develop Minimum Efficiency Performance Standards (MEPS) for major end uses Education Energy efficiency in public buildings
  • 14. ConclusionsSignificant energy efficiency improvements have been seen in recent years: Residential refrigerators: labels + manufacturer initiatives CFLs: consumer awareness + free distribution Building thermal envelope: builder initiativesFuture efficiency improvement: Ban on incandescents (2011) MEPS for refrigerators and air conditioners Eliminate pilots in gas water heaters Labeling and MEPS for gas appliances Labeling of building thermal envelope
