Energy audit in a school building technology, professional and Artistic School of Pombal

In Portugal, energy for buildings accounts for almost 30% of final energy consumption and for almost 62% of electricity consumption. The implementation of energy efficient measures, without compromising comfort level of occupants, can significantly reduce energy consumption in buildings, the energy bills and the correspondent greenhouse gas emissions. An energy audit is the procedure undertaken to identify what, when, and how energy is used in a building and it is the first step to improve the energy efficiency of buildings by identifying opportunities to reduce energy consumption. This paper presents the main results of an energy audit that has been conducted during 2010 in a Portuguese school building - Technology, Professional and Artistic School of Pombal. Besides the main results of energy analysis: energy use profile, global and partial load diagrams, some energy indexes, the paper includes the energy efficient measures identified that can be implemented in the building.
