“…Moreover, energy efficiency actions should strive for cost-effectiveness. Consistent with previous studies [9][10][11][12], the profitability of these actions is measured in terms of their investment and annual energy savings over their useful life (Figure 1). In this context, a reference useful life is considered to compare various actions or sets of actions, providing an indication of their profitability.…”

“…A threshold or boundary point is taken into consideration, referred to as the 'Technical-Economic Zero Point', where the achieved savings from the implemented actions equal the initial investment. Investments to the right of this point have limited potential for cost recovery [10].…”

“…The useful life of all proposals is standardized to ensure comparability [5,[9][10][11][12]; • A correction factor is applied to account for excessive deterioration caused by weather conditions for actions with a significant impact, following ISO 15686 [6];…”

The purpose of this study is to propose optimal actions to improve the energy efficiency of large office buildings in tropical regions with cooling systems, while ensuring the users’ comfort at a reasonable cost. In tropical climates, the building envelope plays a crucial role in saving thermal energy as buildings are exposed to significant climatic impacts and require a significant amount of energy to achieve optimal indoor comfort conditions. In this context, BIM-3D simulation is considered to be effective since it can provide results very similar to those of its physical counterpart, which can be useful for decision making. For this purpose, a public building in Costa Rica is used as a case study, which is modeled in Revit 2019 to obtain a BIM-3D model and simulate its thermal behavior using the BIM tools of the referred software. The architectural characteristics are evaluated in the climatic context of the building, and results are simulated with different configured materials. The obtained results lead to the conclusion that simulation together the previous economic analysis is a valuable decision-making tool for design, enabling significant savings during construction and subsequent building use.
