“…It is confirmed that during the summer, the operation of both rooms is in line with ASHRAE (2020) [86], meeting the acceptability limits for most of the period. It is only outside the limit for 10% of the summer period in both spaces, which aligns with [91,92] and contradicts [93][94][95][96]. However, during the winter, up to 45% of the period in Room A and 40% in Room B fall outside the limits established by [86], in line with the results obtained by [91][92][93]95,96].…”

The present investigation carries out a thermal evaluation of two rooms located in the Royal Hospital of Granada (Rector’s Office). This is a heritage building where have been done studies that allow the as-sessment of possible improvements in future interventions that guarantee improvement in en-ergy and regulatory compliance are decisive. This article presents for the first time, through energy simulation, the behavior of two rooms in two temporal periods, thermally extreme (summer and winter) and with opposite orientations. This has allowed the potential benefits to be considered in real climate conditions. The results demonstrate and quantify that considering the location, orientation, arrangement of openings, and inclusion of transition zones between the exterior and the interior, an improvement in thermal comfort is obtained. The southwesterly orientation is favorable in the winter period and the northeasterly orientation in the summer period. It is also confirmed that the arrangement of thick masonry walls responds adequately in climates with high thermal amplitudes, favoring the mitigation of extreme conditions. It is concluded by stating that the orientation and the construction components are the main responsible factors for the thermal capacity in this type of building. In this context, the use of non-destructive study methods offers valuable scientific support through the results obtained.

“…In 2019, low-income persons accounted for 10.1% of the Canadian population and 10.5% of the American population respectively [16,17]. Social housing and low-income housing are likewise prevalent in cities outside of North America [42][43][44][45][46]. Reviews of indoor environmental quality by Adamkiewicz et al [26] and Diaz Lozano Patiño and Siegel [27] reported that PM2.5 exposure is disproportionately higher for residents of social housing.…”

“…According to Derrick Kajjobat and colleagues [32], the results of questionnaire surveys used to obtain occupant subjective thermal sensation votes indicated that the majority of occupants preferred cooler temperatures during the day, which is supported by the use of adaptive measures to obtain thermal comfort and air quality measurements in naturally ventilated residential buildings in Kampala, Uganda. Although the authors of the research [33] lacked data on comfort in residential environments in intertropical sub-Saharan Africa, they defined principles for developing more comfortable structures in Cameroon based on data from three climatic areas in the country.…”

This article focuses on adopting effective and affordable bioclimatic building design strategies in Ouagadougou, in the Sudano-Sahelian zone of Burkina Faso. A model representing a standard office building and relevant parameters were input in EnergyPlus, and scenarios were analyzed to evaluate the effect of natural ventilation, window shading, dehumidification with night ventilation, and evaporative cooling with night ventilation on thermal comfort and energy consumption. First, the American Society of Heating, Refrigerating, and Air-conditioning Engineers (ASHRAE) Standard 55 adaptive comfort model was used to compare discomfort hours and interior temperatures between a conventional office design and improved models using passive approaches. The simulations further tested the reduction in energy cooling demand and energy consumption. The results demonstrated that natural ventilation was the most effective passive cooling technique, helping to reduce the annual discomfort hours by 40% and the annual energy consumption by 30%. Combining passive strategies is the best scenario, with a year of office occupancy resulting in just 617 h of discomfort, a 42% reduction in the annual energy cooling demand, and a 43% reduction in the annual energy consumption. The simulations demonstrated the effectiveness of affordable passive design solutions applicable even in existing office buildings and their significance for the sustainable development of fast-urbanizing Sub-Saharan countries.
