17. LAWS AND STANDARDS
• LAWS:
- Law 9991 – 2000, investments in R&D and energy
efficiency by utilities
- Law 10295 2001 , energy efficiency law
- Develop energy efficiency
- Minimum efficiency standards
- Buildings on the agenda
• Standards:
- ABNT 15220- Thermal performance (Bioclimatic design)
- ABNT 15575- Minimum performance standard

18. Green buildings

19. Natinal Energy Plan PNE 2030
• Energy Efficiency is
in there for the first
time
• The National Plan
for Energy
Efficiency is coming

20. BRAZILIAN LABELING SCHEME INMETRO
Minimum Efficiency
 Motors
 HVAC
 Refrigerator
 Lamps (phase out of incandescent)

21. BUILDING ENERGY LABELING (Commercial buildings)
INTEGRATED VIEW
Partials:
• Envelope
• Envelope + lighting
• Envelope+ HVAC
Global:
• Complete building
Voluntary for the first 5 years
Etiqueta Nacional de Conservação de Energia - ENCE

22. BUILDING ENERGY LABELING (Commercial buildings)
Two evaluation stages:
 PROJECT evaluation
 BUILDING Inspection evaluation
Project Label Building Label

23. Labeled Buildings
21 Lables
• 40 Buildings under evaluation
• The complete list can be seen in:

25. BUILDING ENERGY LABELING (Residential buildings)
INTEGRATED VIEW
Parts:
• Envelope for summer
• Envelope for winter
•Water heating
•HVAC (only for information)
Global:
• Complete building
Method based on evaluation of room by
room, considering orientation and solar
exposition of each building surface.

26. Conclusions
- Law 10295 2001 , gives the country a good framework for
implementing energy efficiency
- There are standards but the enforcement is very difficult-
Informal market
- Energy efficiency is part of the national energy planning
now
- The national energy efficiency plan is being finalised
- Labels for commercial building are being used
(voluntary) but we still have a long way to make them
compulsory
- Labels for residential buildings are being implemented
this year (voluntary)
