Abstract: Energy simulations are extensively employed by researchers and designers to assess strategies aimed at enhancing the thermal performance or energy efficiency of buildings. However, the methodologies for conducting these simulations and analyzing their outcomes vary according to regional standards and among research groups. This work aims to investigate the methods for evaluating the thermal performance of buildings through energy simulations, through a systematic literature review. Initially, the authors surveyed articles published between 2011 and 2022 on Scopus and Web of Science. From an initial pool of 1463 articles that met the research criteria, a refined list of 158 papers were read completely. The authors examined prevalent trends in the methods and identified future research directions. Most publications originated from authors in Northern Hemisphere, with only Brazil showing expressive numbers in the Southern Hemisphere. The results revealed the three most employed methods: Thermal Load (94 %), Degree-Hour (or Degree-Day) (9 %), and Design Days (5 %). EnergyPlus stands out as the widely preferred software (65 % of studies), and 62 % of them incorporate some form of validation or calibration. Articles often lack complete simulations parameters and/or clarity in their presentation. In response to the identified gaps, this study introduces a checklist of best practices for presenting the simulation steps. As such, this work serves as a valuable theoretical framework for future assessments of building thermal performance through computer simulation.
