“…Some studies showed that the standards have limited suitability in environments such as educational buildings, as they were developed based mainly on adult subjects working in offices. Therefore, alternative methods such as the one proposed in [24,65] are needed for comprehensive data gathering within different contexts.…”

The analysis of thermal comfort in buildings, energy consumption, and occupant satisfaction is crucial to influencing the architectural design methodologies of the future. However, research in these fields in developing countries is sectorised. Most times, the standards to study and assess thermal comfort such as ASHRAE Standard 55, EN 15251, and ISO 7730 are insufficient and not appropriate for the geographical areas of application. This article presents a scoping review of published work in Colombia, as a representative case study, to highlight the state-of-the-art, research trends, gaps, and potential areas for further development. It examines the amount, origin, extent, and content of research and peer-reviewed documentation over the last decades. The findings allow new insights regarding the preferred models and the evaluation tools that have been used to date and that are recommended to use in the future. It also includes additional information regarding the most and least studied regions, cities, and climates in the country. This work could be of interest for the academic community and policymakers in the areas related to indoor and urban climate management and energy efficiency.

“…To solve this distance, more fieldwork should be performed before methods are included in standards [63]. This proposal from 2002 remains open, with subsequent research confirming the need to improve the procedures defined by the standards [64] Field studies on thermal comfort confirm that personal understanding conditions the evaluation, and the results can vary depending on context and time. This situation confirms the changing relation between people, climate, and buildings posited by some authors [65].…”

Evaluation of Energy Performance and Comfort: Case-Study of University Buildings with Design Adapted to Local Climate

et al. 2021

One of the main strategies to reduce countries’ energy bills is to invest in efficient buildings. To achieve this objective, the European Union Member States have developed different methodologies to evaluate building energy performance, which are often supported by simulation tools. These tools are based on calculation engines that use databases and simplifications to attempt to bring their results close to real building performance and are mostly designed to be used at the end of the process, neglecting their role in project decision-making processes. To compensate for this situation and to obtain the most accurate results, the methodologies recommend previous work during the building design phase to adopt passive design solutions that learn from experience and aim to adapt the building design to the local climate. However, these design solutions are difficult to adopt while working with medium to large public buildings and are often not properly understood by the simulation tools. In addition, new BIM methodologies are being implemented, starting to enable proper interaction between the designer and the results, and opening up the option of introducing other types of calculations, such as building comfort, in the calculation process. Among the group of countries with limited simulation tools that are starting to be substituted is Spain, which recently launched its first BIM-based energy simulation tool. This tool aims to compensate for the limitations of the former simulation tools and opens up the option of performing comfort calculations by sharing information with other programs. The objective of this research is to evaluate, from different perspectives, the performance of this new simulation tool on three buildings at the University of Alicante. These were chosen as university campuses are responsible for large groups of buildings and belong to the group of stakeholders interested in obtaining efficient and comfortable buildings. These case studies are defined by their extreme adaptation to design recommendations for mild-warm weather. At the end of the process, the difference is measured between simulation and real building performance. The results obtained show that simulation still differs greatly from real building performance from the energy performance point of view, while the comfort evaluation shows results that are closer to the reality of the buildings.

“…Consequently, indoor air quality in schools has a strong impact on children's exposure to air pollutants and can also influence their learning capacities (Mendell and Heath, 2005;Simoni et al, 2010). Indoor air quality in schools is usually characterized by a range of parameters including temperature, relative humidity, and levels of carbon dioxide (CO2), ventilation rates and average concentrations of gaseous pollutants (Gaihre et al, 2014;Jiang et al, 2018;Rodriguez et al, 2019;Verriele et al, 2016) although there is no specific guidelines to assess IAQ in classrooms. These latter are usually determined by a single measurement over 4.5 or 7 days of passive sampling.…”

This paper presents a field campaign conducted in two French elementary schools for 5 weeks aiming at identifying effects of occupation and ventilation practices on indoor aldehyde concentrations and discriminating aldehyde emission from building materials and furniture. The investigated classrooms were first empty and not occupied whereas the furniture was added the following week. Normal school activities were restarted for the last three weeks under various ventilation practices. C2-C7 aldehydes concentrations were monitored with the conventional method based on DNPH derivatization using active sampling followed by off-line HPLC/UV analysis. Acetaldehyde (AA) and hexanal (HA) were the two main aldehydes present if formaldehyde is not considered. The weekly mean values of acetaldehyde concentrations were found in the range 9.5 -13.1 µg m -3 (School 1), 9.4 -17.6 µg m -3 (School 2) and equal to 5.3 µg m -3 (School 3). In Schools 2 and 3, weekly hexanal concentrations ranged between 3.3 and 5.4 µg m -3 but increased up to 40.1 µg m -3 in school 1 where painting work was performed during the week 2. Smaller amount of propionaldehyde (PA) and benzaldehyde (BA) were always detected, their weekly average concentrations being in the range 0.4 -4.0 µg m -3 and 0.9 -2.7 µg m -3 for PA and BA, respectively. The results supported by Student's tests show that building materials and furniture contribute to aldehyde emissions while ventilation significantly improves indoor air quality without being able to privilege one of the three ventilation scenarios tested.
