The convenience of the use of environmental building evaluation tools, to know design conditions and thermal behavior, by using bioclimatic strategies for determining a good early design processes of the building, as well as an evaluation of energy consumption of buildings and for the behavior of building the use of BPS - building performance simulation tool to control the power state of the building, the emission of carbon dioxide CO2, natural lighting and thermal comfort and a CFD - Computational Fluids Dynamics analysis. We take a deeper look about the behavior of the buildings by the use of the Design Builder software, as main practice objective, to show this we explain the process to work with a BPS - building performance simulation: Pre-process, Simulation process, Post-process. This material was presented in a European Union Cost Action TU1104, Training School in Belgrade (Serbia) in 20 - 23 April of 2015.

To COST ACTION TU 1104 "Smart Energy Regions" Prof. Aleksandra Djukic and Prof. Aleksandra Krstic-Furundzic of the Faculty of Architecture of the University of Belgrade, Serbia, that gave us the opportunity of be part of the training school imparted from Monday 20th to Thursday 23rd April 2015, where we can teach the topic.
