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

Labeled Buildings

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)
