Retrofit demonstration in Brazilian commercial and public buildings.

In order to help the development of energy efficiency building standard in Brazil , to demonstrate state of art technologies and to encourage the use of hourly energy simulation tools the National Energy Conservation Program (PROCEL) has started the "6 Cities Project". The project is being developed in six cities around the country. For this project a standard methodology was developed and applied. The methodology consists of a survey in the local utilities to establish the highest energy consumers in the commercial and public sector. A data-base is being created with information o n energy consumption intensity and demand intensity in 15 buildings in each city. The data-base was designed to help the standards development. Among those buildings, in each city, two were selected, one is a public building and one a private building, for a detailed energy audit. The audit data was used to calibrate a DOE2 simulation model. Simulations were performed and state of art technologies for energy efficiency are being tested and will be implemented. An after retrofit monitoring program is planed. In this paper the results of the first buildings will be showed.
