The building sector consumes more than one-third of the electricity produced in many countries, mainly due to heating, ventilation, and air conditioning practice. This estimation is e even higher in countries geographically located in hot and arid regions because the need for air cooling is crucial. This is particularly true for Saudi Arabia, where the building sector’s share in electricity consumption has reached around 80% of the electricity produced. Hence, the influence of environmental factors on building energy consumption has been a topic of focus. This work investigates the effects of applying energy rationalization for a non-residential building in Saudi Arabia. As a case study, a laboratory room at King Khalid University College of Engineering Campus was modeled using Simulink as a typical educational building. The aim was to study all involved cooling loads to assess the amount and cost of the cooling energy required for the building and to search for the influence of selected procedures to rationalize it. Three categories of rationalization measures have been identified, and one measure from each category has been selected and applied. The results show the impact on energy consumption and cost when applying these measures both exclusively and mutually. The best energy rationalization performance reached for an individual action was 17.72%, while a total reduction of 28.38% in energy consumption and cost was obtained when all three selected measures were applied collectively.

“…Worldwide concern about climate change, environment protection and energy consumption in residences and buildings has motivated researchers, engineers, architects and professionals to conduct extensive efforts to develop efficient systems, materials, equipment and design (Suliman et al, 2021, Shari et al, 2021. In the last three decades, considerable amount of research work focused on the use of solar chimney, stack effect and skylight to play multiple roles including heat gain reduction, ventilation and daylighting.…”

This paper reports experimental performance of a new modular configuration of roof integrating skylight and solar chimney intended to reduce heat gain admission, induce ventilation and ensure sufficient indoor illuminance. This integrated Skylight Solar Chimney (SSC) configuration is composed of three layers: a 1mm thick clear acrylic layer on the outside, a set of 1 mm thick aluminum slats distanced each other at the middle and a layer with a combination of clear acrylic and aluminum slats at the inner side. To assess SSC performances, two small rooms of 2.52 m3 volume were built using concrete blocks for walls and corrugated cement panels for the south facing roof slopped at 30 degrees. The roof of the first house, which served as a reference, integrated a transparent corrugated panel whereas the other house integrated our SSC. The dimensions of the SSC are 0.50 m x 1.50 m x 0.15 m (W x L x H). A 0.025 m2 outlet opening was located at the top lateral side whereas two inlet openings of similar surface area were installed on the bottom lower layer (one inside the room and another outside). Field test results showed that in all scenarios considered the indoor temperature of room with SSC was 1 to 4 °C lower that of the reference room and varied following ambient conditions. When both inside and outside inlet openings were used, the highest temperature difference was observed. The measured heat flux through the roof of reference house was much more important than all SSC scenarios, a 50% difference was observed when both SSC inlets were open. This clearly demonstrated SSC efficiency to reduce heat gain. The air change (ACH) induced varied between 2 to 29. SCC indoor illuminance was about 50% lower than that of the reference house.
