“…With a concentration near 500 ppm, the employees were thermally satisfied compared to occupant s experiencing indoor conditions near 900 ppm. Additionally, [14] in 2021 presented a numerical study related to the performance evaluation of ventilation systems in the Technological University of Panama. The purpose was to determinate if the students were getting high indoor air quality with natural ventilation and mechanical ventilation, considering air renewals, CO2 concentrations and thermal 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.

Air quality, specifically in indoor environments, has become a growing concern. In general, people tend to spend most of their lives indoors due to the growing urbanization. Indoor air quality is associated with ventilation rates, academic performance, and occupant’s health due to the presence of indoor pollutants. Exposure to these contaminants is a risk factor for people to develop the sick building syndrome. The objective of this study was to determine an optimal hybrid ventilation strategy in a tropical climate, favoring natural ventilation with different proposed strategies, varying the opening of doors and windows, the opening time, and the occupancy, among other aspects and strategies using dynamic simulation. The results were compared with in-situ measurements and surveys conducted on students in the case study. Of the proposed strategies, it was decided as optimal hybrid strategy to increase the fresh air intake from 5 L/s*person to 10 L/s*person with the use of mechanical ventilation and reduction of occupancy, this way, in addition to improving indoor air quality, the thermal comfort of the students was ensured.

Ensuring that ecosystem services are effectively maintained and integrated while also proactively adapting to the challenges posed by climate change is essential for developing sustainable and resilient housing in both new and existing settlements. The tropics cover roughly 40% of the world and are home to about 40% of the global population. By the late 2030s or 2040s, 50% of the world’s population is projected to live in the tropics. This research project investigates the intersection of sustainable construction and energy security for achieving sustainable and resilient housing in tropical climates. Examining (1) resilience strategies against climate change impacts and (2) case studies led to highlighting best practices regarding construction and energy security aspects. Finally, a reference framework is provided for architects, policymakers, and stakeholders involved in tropical housing development.
