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 labeling
Standard or Year Description

IRAM 2404-2 2000 Measurement of noise
IRAM 2404-3 1998 Label design
SICyM 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:

7. Residential lighting energy use
Government programs:
2008-09: Distribute 2 CFLs per household to all households
Jan. 2011: Prohibition of sales of most incandescent lamps

8. Labeling extended to lamps
Standard or Year Description
Resolution
IRAM 62404-1 2005 Incandescent lamps
IRAM 62404-2 2006 Fluorescent lamps
SICyM 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

13. Exec. Order 140 (2007)
National Program for the
Rational and Efficient Use of Energy
Key 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. Conclusions
Significant energy efficiency improvements
have been seen in recent years:
Residential refrigerators: labels +
manufacturer initiatives
CFLs: consumer awareness + free distribution
Building thermal envelope: builder initiatives
Future 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
