ABSTRACT :
The present work is aimed at evaluating the results obtained during the first year of operation of a public building with high energy rating in Extremadura (a southwest Region of Spain), which it puts into practice techniques on saving and energy efficiency in buildings and renewable energy integration. The building has been built taking into account the climatic conditions of the city of Mérida (Spain), applying concepts of passive solar collection and thermal insulation, shading of windows and roofs, using natural lighting and technologies based on the integration of renewable energy.
The results shows that it is possible to weatherize public buildings in cities of extreme weather by implementing measures that minimize energy consumption and using renewable energy sources (solar and biomass), demonstrating the economic viability, energy and environment of that buildings.
It is a public buildings to use administrative and non-experimental with energy rated "A", operating since 2010 in Spain, which serves as an example to society of the efficacy of energy efficiency techniques. It´s larger than 5,000 m2, its particular envelope based on a production facility using biomass combined heat engine cycle with a single effect absorption, the ventilation free-cooling system and the integration solar thermal and photovoltaic, make it an international benchmark.
