One major barrier to economic development is the growing global demand for energy and the consequent increase in the use of natural resources to provide it. Developing countries such as Brazil, showed progressive energy consumption per capita in recent years. Although the majority is from hydroelectric plants (non-polluting sources) its construction causes great environmental impact. Percentage of all energy generated, buildings are responsible for the consumption of approximately 40 % and this percentage is likely to increase by the growth of the construction industry in the country. Regarding the problem, the fight against waste, streamlining and sustainable use of energy consumed by buildings are directly linked to the reduction of environmental impact, delaying the need for increased national energy matrix. In this context is created the Technical Regulation of Quality Level Energy Efficiency Commercial Buildings, and Public Service (RTQ - C). This work consists of a critical application of the RTQ - C using a prescriptive methodology, with the focus aspects of their applicability and evaluation of thermal comfort and luminal, with the premise that the high energy performance of the building is fully achieved only when conditions are guaranteed satisfactory environmental comfort to users. Therefore it was necessary to step thorough data collection and measurements "in situ" of air temperature, radiant temperature, illuminance and relative humidity in two rooms (laboratory of comfort and classroom 2) building the Center of Excellence in Efficiency energy from Amazon - CEAMAZON subsidizing the use of the methodology proposed by Fanger (PMV and PPD), and verification of illuminance levels proposed by NBR 5413. As a result the building showed good performance, but the lack of compliance prerequisites rated with "C" level. A comfort evaluation indicated that approximately 23% of users have had on thermal comfort and the natural ventilation can be used as a strategy to climatic adaptation. Illuminance measurements indicated that only the classroom 2 possessed potential use of natural lighting during the measurement. It was concluded that, despite its importance, the RTQ - C must still pass through a process of adaptation by society and professionals involved in the energy certification of buildings and that during this period changes may be incorporated contributing to make it a effectively valid instrument for ensuring the energy efficiency of buildings in the country.
