• simulation method: more complex, it uses software that allows the incorporation of new technologies in terms of materials (construction and thermal insulation), and passive and active conditioning strategies, among others. At the end of the evaluation process the building labelling (design or existing) receives a Label as showed in Fig. 1.

Labeling process analysis The methodological procedure for assessing the level of energy efficiency for Building Labeling is contained in the RTQ-C Manual (PROCEL, 2017). As preliminary analysis, it should be stated if a building (design or existing) attends some prerequisites related with electrical circuits and hot water systems, that allow to establish if the overall label can reach level A or not. From this point, the analysis can proceed to find out the partial Efficiency level for: Envelope, Lighting and Air Conditioning. In addition to these, Bonuses could be considered for the upgrade of the Overall Efficiency Level of the building. The labeling is composed of steps for the analysis of three separated system (Partial) and for the entire building (Overall): • Envelope: made with the determination of a set of indices referring to the physical characteristics of the building. • Lighting System: determined by calculating the power density installed by the internal lighting, taking into account the activities carried out inside of building. • Air Conditioning System : divided into two classes: the first is the one that makes up the individual and split components that are already classified by INMETRO (National Institute of Metrology, Quality and
