Partial classification of block 3 of the complex of the Engineering School of UFMG by INI-C

Abstract

The present work aims to apply the new construction method of the Normative Instruction for Services of the Normative and Public Instruction for the Energy Efficiency Classification (INI-C), published in March 2021, for the energy efficiency of lighting and envelope systems for delivery of partial ENCE. The object of study is the Block 3 of the UF School of Engineering, a higher education building compound by 3 connected blocks, named for analysis purposes as blocks A, B and C. The blocks are within the limit of application of the metamodel for thermal load calculation temperature (CgTR), but it was not used to manufacture the heating hours tools (FHdesc), for which adjustments were made in the end, the envelopes were classified as A and the lighting systems were classified as B. The analysis allowed to indicate bottlenecks of the new method, and it is considered that there was evolution in relation to the RTQ-C although, in the evaluation of the performance of the envelope, there is difficulty in the division of thermal zones in buildings of more complex geometry. It was also not possible to consider the existing shading of both unopened walls and caused by afforestation, quite present in the Campus. It is also considered that the efficiency rating of the artificial lighting system is permissive, allowing good classification for systems that still use fluorescent technology, less efficient than the current LED technology.
