Nearly and net zero energy buildings have been strongly studied in the global north, with generally a temperate climate, thus focusing on energy-efficiency measures for such climates. Few existing zero energy buildings can be found in tropical and humid climates, where most are ongoing state projects or research projects. Therefore, this chapter brings forth and analyzes the energy-efficiency measures implemented to retrofit buildings in tropical and humid climates to achieve zero-energy buildings. The first part analyzes the measures by energy measure according to building type and climate, envelope (passive and active cooling), energy systems, dampness and mold growth, occupant (thermal comfort and the occupant), renewable energy system (BIPV rooftop and facade BIPV installation), and retrofitting aspects. The second part presents and discusses a proposed framework for policy implementation for building retrofit toward NZEB in Panama based on current building regulations and research evidence, and the viability is assessed via a SWOT analysis.

“…The factors considered were the number of occupants (X1), air conditioning (AC) (X2), light bulbs (X3), fans (X4), areas of the house (X5), floor area (X6), age of occupants (X7), thermostat adjustment (X10). This section seeks to find the behavior of energy consumption depending on the occupant's preferences as far as the use of appliances is concerned [27].…”

Buildings are highly demanding of global energy consumption. Their functions, design, location, and other parameters influence the magnitude of such consumption. However, a key factor that can significantly change energy demand is the occupant’s interaction with the environment. It is, therefore, prudent to integrate the occupant profile within the six determinants of energy use, as proposed by the International Energy Agency. International standards propose an occupancy profile that has been implemented for design and performance analysis. However, these do not reflect reality, have little precision in their results, and affect occupant comfort and energy consumption expectations. To mitigate this problem, the literature proposes various methodologies to establish a mainly stochastic analysis offering optimal results. Panama, a country in the process of improving its energy matrix, finds it convenient to apply studies on the occupants’ behavior (OB) and preferences to guarantee comfort and avoid energy losses, supporting the purposes established in the National Energy Plan of Panama 2015–2050, guiding energy policy. This research seeks to define a particular pattern in occupants’ behavior in Panama through the analysis of surveys, identify its impact on energy consumption through dynamic simulation, and compare it with energy consumption generated by international standards. Results showed great differences in the energy consumption estimated via typical OB-based surveys and OB from standards, where the consumption by the latter can increase above 50%, while with surveys, this differs from the reference by no more than 11%.

“…Due split units don't provide an air change rate, this may have an impact over IAQ, in other words, rising pollutant concentration. González et al [11] discovered by employing a survey analysis to know occupants' preferences that most participants in the study, selected split air units as their cooling systems, thus it's the most common and known mechanical ventilation system utilized. In contrast, [12] showed that occupants of buildings with centralized ventilations system were thermically unsatisfied compared to occupants who worked in spaces with split units, since with this type of ventilation, the user can control the interior temperature at his comfort.…”

Air quality plays a decisive role in the performance of the occupants considering that people spend at least 70% of their life indoors. This research aimed to determine if an air split unit in a small public office provide appropriate air quality for its employees. The ventilation performance was evaluated in passive and mechanical mode; the dynamic interface DesignBuilder simulated three case studies: the first one was to validate the data obtained with a temperature sensor during 10 workdays, the following two compared exclusively mechanical ventilation and exclusively natural ventilation with all windows and doors opened. The indicators utilized were CO2 concentration, indoor air renewal rates, and thermal comfort. The results showed that natural ventilation is insufficient to ensure high indoor air quality due to thermal discomfort, but acceptable CO2 concentrations were registered. In contrast, mechanical ventilation improved thermal comfort levels, but the CO2 concentration remained slightly outside the acceptable limits. These results demonstrated that the office is not designed to operate passively, restricting their functionality with mechanical ventilation.
