RESUMO:

It is estimated that the energy saving potential in new buildings can reach 50% (PROCEL, 2015). Several studies carried out for the Natal-RN climate reinforce this trend and have demonstrated a vast potential for reducing energy consumption in buildings, in addition to identifying the significant influence of architectural features (LIMA, 2007a; SIMAS, 2009; RODRIGUES, 2014). However, a choice of architectural solutions based only on the potential of reducing energy consumption is very restricted. The support in economic criteria and the adherence to existing regulations, such as RTQ-C, make the decision-making process more comprehensive and appropriate. This dissertation analyzes the implementation of architectural alternatives in a public building project in the Natal/RN climate, based on the comparison of its economic impacts and energy performance. By means of computational simulations, the implementation of 8 (eight) recurrent alternatives in two partially conditioned buildings of the type B PROINFÂNCIA / FNDE program project was analyzed. The impacts on the reduction of the consumption of cooling energy, on the level of energy efficiency of the envelope by the RTQ-C and the economic feasibility were verified. Almost all alternatives showed efficiency in minimizing the consumption of cooling energy, with a reduction potential of up to approximately 26%. However, only four of them are able to raise the label level to "A". As for viability, only four were feasible, which occurred much more due to the substitution of materials for cheaper ones than for the financial benefit of reducing energy consumption. The results show that the alternatives with better energy performance may not represent the best solutions of a project. In both buildings, the solution that most positively impacted the energy efficiency in relation to consumption and labeling (alternative "b": Clear colonial ceramic tile with precast slab lining) proved economically unfeasible. The alternative "c" (clear colonial ceramic tile with plaster lining) was the only alternative that, in addition to being feasible, also reduced the consumption of both buildings and reached level "A" label, which also contributed to highlight the effectiveness of the use of light colors on the roof.
