Application of the 6D BIM approach in the evaluation and energy rehabilitation proposal of public educational infrastructure

Abstract

INTRODUCTION. When approaching the design of a building, one of the primary objectives is to create an interior environment that promotes the health and comfort of its occupants. OBJECTIVE. The research seeks to evaluate through 6D BIM the energy performance of the prototype educational infrastructure built in Ecuador, in a case of the city of Loja, in order to know the comfort parameters, compare them with what is exposed by the normative bases and propose an energy rehabilitation proposal to improve comfort and reduce the energy consumption of the building. METHOD. The process is carried out through virtual test-tube simulation in Revit software and its simulation engine EnergyPlus to know its energy performance. Based on this, strategies to improve thermal and lighting comfort and air quality in the building are proposed and validated. RESULTS. The results show that the equipment does not comply with the comfort ranges according to the zone where it is located, with an interior temperature of 17.88°C, lighting levels of 3500 lumens, RH of 60% and 51 MWh/y of electricity consumption. DISCUSSION AND CONCLUSIONS. The proposed intervention has demonstrated significant improvements, including an increase in temperature by 6.18°C, a reduction of 2300 lumens in lighting, a 10% decrease in relative humidity (RH), and reduced electrical consumption to 42 MWh/a. These results consolidate this intervention as a highly replicable and energy efficient alternative for similar infrastructures.
