“…Moreover, it could also aid in the cooling effect by absorbing significant amounts of moisture from the Science and Management Volume 16 Number 4, June 2021: 124-136 atmosphere during humid nighttime hours, with the evaporation process occurring the next day (Lokko & Rempel, 2018;Vailati et al, 2018). Furthermore, the hygroscopic properties of wood as an adaptive sunlight shading device could reduce energy costs, improve energy efficiency and enhance indoor comfort in buildings (Hammad & Abu-Hijleh, 2010;Palmero-Marrero & Oliveira, 2010;Vailati et al, 2018;El-Dabaa et al, 2020).…”

“…The proposed wooden louvred window panel can also provide protection from the rain splatter while allowing the air outside to come inside. Besides, wood material could be used as a façade shading system, in which due to its hygroscopic properties, it could be advantageous for occupants as it could lead to decreasing in energy cost, enhance energy efficiency and improve indoor comfort in buildings (Vailati et al, 2018;El-Dabaa et al, 2020). When wood is applied, it gives a passive motion technique stimulated by the variation of relative humidity which can be ideal in a tropical climate.…”

Window ventilation usually used in energy-efficient buildings as an effective natural ventilation system to provide an adequate opening for fresh air to flow into the interior space. It could help to reduce the indoor air temperature and limit the contaminants in buildings. This study aimed to visualise the airflow structure across a wooden louvred window panel using the smoke flow visualisation technique at different airflow speeds of 0.5, 1.0, 2.0, 3.0 and 5.0 m/s in a closed-loop wind tunnel. Two Sony 1920 × 1080i cameras captured the airflow structure, which took the side view, rear view, front view and back view images. The wooden louvred window panel promotes optimum outdoor airflow and facilitates continuous air exchange to replace the indoor air. Results showed that smoke filled the space quickly at the highest airflow speed of 5 m/s. This study used an inclination angle of 75° for the wooden louvred window panel to avoid rain splatter. Besides, wood material could be used as a façade shading device.Therefore, installing the wooden louvred window panels could enhance natural ventilation, ensure indoor thermal comfort and reduce indoor air contaminants.
