Recovery of ancient bioclimatic strategies for energy retrofit in historical buildings: the case of the Infants’ Tower in the Alhambra

CFD Evaluation of Thermal Conditioning in a House of Social Interest with a Solar Chimney Arrangement in Guanajuato, Mexico

“…The speeds are concentrated in the central part, which is the most occupied space, so providing air flow in this area is more important. We observe in Figures 11 and 12 that an air flow velocity is obtained in both rooms without counting on an external outside flow (wind speed of 0 m/s), with values similar to those obtained by the measurements of Di Turi et al [44] for bioclimatic strategies of natural ventilation considering external flow, and 10% of the speeds reached in the works of Reyes et al [21], for the optimization of the internal air flow through a wind tower. From the point of view of air renewal, important levels are achieved, 38.2 ACH (Air changes per hour) for room 1, 57.4 ACH for room 2, and 19.14 for the common area, comparable to those reported by Z. Zhai at al.…”

Dynamic thermal and hygrometric simulation of historical buildings: Critical factors and possible solutions

“…In such regard, in the framework of the International Energy Agency (IEA) Task 59, "Deep renovation of historic buildings Towards lowest possible energy Demand and CO 2 emission (nZEB)" and more in particular in the subtask B.5 "Characterization and simulation of historical buildings", the most significant researches in building simulation applied to historical buildings have been reviewed, studying issues of model creation, set up, and experimental validation. It should be noted that the use of CFD software in the built heritage has been already addressed in other works [49][50][51][52][53][54][55][56][57], and a deep review has been already published [58]. For this reason, this topic is not covered in the present review.…”

Natural ventilation for office building retrofit in dense urban context under hot and humid climate

“…Without changing the window-to-wall ratio (WWR) and the facades' main features, satisfactory indoor air change could be reached by the different possibilities of the louvre's operation. Turi et al (2017) also highlight the influence of windows' operation on recovering the natural ventilation efficiency of the Infants' Tower in Alhambra. The study underlines the importance of the original celosías for the energy and thermal comfort upgrading during summer, and defend an in-depth investigation of passive strategies to reduce the installation of invasive plant solutions.…”

“…In contrast to new constructions, several design variables are already defined in existing buildings, such as its placement and form, the position and dimension of openings, and internal layout. This task is even more complex when preserving the envelope's original characteristics is a concern, as in historical buildings (TURI et al, 2017) In the last 20 years, numerous studies have focused on passive strategies for existing buildings to reduce its energy consumption and the overheating effects in summer due to excessive thermal insulation. In projects such as IEA Annex 35 (INTERNATIONAL…, 2018a), Revival (GAUDIN; GAUDIN, 2006), School Vent Cool (ERACOBUILD, 2018, and IEA Annex 62 (INTERNATIONAL…, 2018b), hybrid ventilation emerges as one of the most efficient systems for different climatic contexts, since it combines all the best features of natural and mechanical ventilation to promote thermal comfort and indoor air quality throughout the year.…”
