“…Applying natural ventilation can achieve satisfactory comfort and a healthy indoor environment. Enhancing air velocity increases the occupant's sweat evaporation with thorough ventilation (Castillo & Huelsz, 2017). Considering the excellent air circulation (Kim & Kim, 2018), natural ventilation provides fresh air and reduces future health problems.…”

Incorrect implementation of window parameters, such as configuration, position, and size, cause an unpleasant indoor environment. The authors reviewed window performance in a hot and humid climate in this paper. Articles were screened in detail to determine eligibility, compiled, and organised according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) requirements. The articles included in this review concerned natural ventilation and window performance in a hot and humid climate. Keywords or topics were reviewed and focused on indoor environment comfort. The results demonstrated that sliding windows were unfavourable openings that were nevertheless in demand. This review was performed to guide consumers, designers, and the market of the built environment industry.

“…Furthermore, studies have shown that natural ventilation inside an enclosed space in a humid climate is beneficial for three reasons: promotion of thermal comfort, air purification inside buildings, and lower energy consumption [10]. In addition, natural ventilation reduces carbon emission [14] and increases energy costs by 40% compared with air-conditioned buildings [15]. Algeria is no exception.…”

This study tested the effectiveness of some natural ventilation basic configurations for the thermal comfort of occupants in different local climates in Algeria. Due to the diverse Algerian climate, the study was performed during the mid-season period that includes three months of May, September, and October and the summer that includes the months of June, July, and August. The ventilation potential of the selected configurations was analysed through numerical simulation by using TRNSYS software coupled with COMIS aeraulic software. The results showed the significant contribution of natural chimney ventilation caused by a stairwell to improve occupant comfort. However; its integration requires a judicious and permanent inspection to control temperature decreases or overheating risks.

“…Natural or mechanical ventilation systems needed in buildings for removing air pollutants and providing fresh air into occupied spaces [10]. For buildings where the energy consumption is high, natural ventilation is the best way to reduce energy consumption [11,12] and, moreover, the cost of energy used in naturally ventilated buildings is 40% cheaper than energy used for air-conditioned buildings [13]. Naturally ventilated buildings should integrate window to wall ratios, orientation, glazing properties, and visual and thermal comfort ideas that are designed properly in an architectural sense to maximize efficiency [14].…”

Air changes per hour (ach) rates for windows of different sizes and opened in different ratios were studied to establish natural ventilation concepts in offices with a Mediterranean climate. Dynamic thermal simulations were carried out in EDSL Tas for whole year investigations of an office. The office lost 0.01 W of heat during the winter but gained 0.01 W of heat during the summer. Annual average heat gain was 2.4 W. The heat gain via an external opaque wall was 138.9 W during the winter and 227.3 W during the summer, with an annual average of 190.7 W. The heat gain via an external glass surface was 128.9 W during the winter and 191 W during the summer, with an annual average of 161.5 W. The office had an average of 170.0 ach during the winter and an average of 144.7 ach during the summer, with an annual average of 157.4. The maximum annual ach performance was 480.4 ach when the external wall was fully glazed and the window was fully open, and the minimum annual ach performance was 9.8 when only 10% of the external wall was glass and 20% of the window area was open.
