“…Following the validation, a sensitivity analysis is undertaken to reveal that around 45% of the building energy use goes to the HVAC systems aligned with the values provided by Refs. [ 18 , 19 , 25 , 29 , 30 ].…”

“…The DOAS system is a conceivable alternative HVAC solution supplying the exact amount of recommended outside ventilation air required by each zone [ 19 ]. The air is introduced at lower dew-point temperatures, allowing it to absorb the space latent load as well as a portion of the sensible load, effectively decoupling the latent and sensible loads [ 18 , 19 , 32 ].…”

“…They added that the upcoming difficulties, include maintaining a constant focus on recognized risks and handling practices transition when new objectives and issues emerge. In hot climatic regions, William et al [ 18 , 19 ] investigated the effectiveness of the dedicated outdoor air system (DOAS) on a healthcare facility's energy consumption. On the other hand, and with the global concerns about mucormycosis, it is brought to our attention that HVAC systems can effectively enhance the control of moisture indoors, eliminating the growth of mold.…”

“…From both energy simulations and empirical analysis, it can be used to identify the key variables influencing building thermal performance. Analyzing the building energy use, approximately, HVAC systems compromise half the building energy use, which aligns with 9,10,13,17,67 . A sensitivity analysis was undergone for the validated baseline model to quantify the portion of each parameter affecting the building energy usage, as illustrated in Figure 6.…”

Summary The worldwide environmentally friendly trend has focused the last decade on emphasizing the value of energy conservation and reducing the carbon footprint in buildings, achieving zero energy buildings. Presently, viable building techniques, in developing countries, are insufficient to achieve zero energy buildings. Thus, authorities should implement policies mandating new developments and renovations to establish “energy‐efficient buildings”; nevertheless, design solutions should be properly evaluated and assessed preceding execution. The conservation of energy without jeopardizing human comfortability is a huge challenge for any designer. Occupants are less interested in making a major investment to save some expenses over the next two decades, especially nowadays that energy is still affordable. Therefore, improved indoor environmental conditions are perhaps another important parameter toward energy‐efficient buildings. Through dynamic simulations, this study examines the energy efficiency and thermal comfort achieved by integrating retrofitting strategies in an institutional building in three different American Society of Heating, Refrigerating and Air‐Conditioning Engineers (ASHRAE) hot climate zones represented by three cities of Egypt (Aswan, Cairo, and Alexandria). The built‐up baseline model is validated using actual energy usage data. The validated baseline model is then subjected to local sensitivity analysis to determine the driving parameters influencing the building's energy demand. The study at hand focuses on a broader perspective on sustainability. With a multiapproach decision‐making methodology based on the most recent measures, the study highlights the outcomes through an environmental–economic assessment and indoor thermal comfort depending on experts' weighting, responses, and recommendations. The outcomes postulate that the implementation of reflective paints solutions would achieve the highest percentages of whole‐building energy savings with 21%, 19%, and 17% for Aswan, Cairo, and Alexandria, respectively, improving indoor thermal comfort levels.
