Building Energy Analysis of a School Building using Revit

Abstract

Global warming and environmental issues have driven the demand for high efficient buildings.
The integration of Building Information Modelling (BIM) and energy assessments tools to the
construction process have contributed to proper selection of building materials and significant
reduction in energy consumption. With BIM, the energy consumption is an integrated part of a
building design, where energy analyses begin at the conceptual stage of the project. This study
considers an energy analysis of a school building located in Spain. The building is an object of
study in an inter-university project between INTI International University and another Spain
university in 2018. Upon the completion of that project, the authors become interested in the
energy usage of the building, which has not been completed then. The new analysis uses Autodesk
Revit to develop a Building Performance Analysis (BPA) and to predict its energy performance,
including the consideration of building materials and weathering effects. The analysis is able to
estimate the CO2 emission, cooling and heating loads, and the electrical usage of the building.
With a single and modern workstation, an engineer can carry out the complete analysis of a small
building with ease.
