The effects of indoor conditions on the reduction of energy consumption in commercial buildings in rio de Janeiro

Most of the Brazilian population is concentrated in the shore region in cities like Rio de Janeiro. In this town, there is a large number of mechanically conditioned buildings with no possibility of use of natural ventilation for passive air conditioning. Due to the diversified cooling load profile, the use of detailed software simulation is essential. This paper presents the cooling load and energy consumption simulation results for a commercial building using the softwares BLAST and NBSLD. The indoor conditions are changed to analyze the thermal comfort impact and energy reduction. It is also presented considerations about the adequacy of the simulation models to the Brazilian conditions
