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
Green buildings
not big progress in energy efficiency missing opportunities

BUILDING ENERGY LABELING (Residential buildings)
Etiqueta Nacional de Conservação de Energia - ENCE
Parts:• Envelope for summer• Envelope for winter•Water heating•HVAC (only for information)
Global:• Complete building
Method based on evaluation of room byroom, considering orientation and solar
exposition of each building surface.
INTEGRATED VIEW
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)
