“…and energy consumption can be reduced by 23.6% annually. Al Jubori et al [33] performed energy simulations to evaluate the building's energy utilization in terms of various efficient techniques. The reduction rate for cooling percentage was: Changing the orientation to north 1.1 %, double glazing 7.7%, building insulation 16.0%, Control for shading 1.6%, smart ventilation control 5.5%, cooling system scheduling 3.1%.…”

This study aims at thermal comfort improvement in residential buildings through utilization of passive design strategies and energy efficiency measures. The study investigates the impact of passive strategies on thermal comfort in hot dry climate of Egypt. A climatic analysis of three cities: Aswan, Cairo and Alexandria was conducted to examine passive design strategies’ efficacy. Thermal comfort in a residential building was examined by DesignBuilder simulation software. Annual simulations were performed on the model where several passive design strategies were applied. Passive design strategies’ potential was quantified and a parametric analysis was conducted for thermal comfort improvement. The results demonstrate that applying passive design strategies can be effective in reducing discomfort hours in hot climate. Comfort hours could be increased from 22.6% to 33.1 % in Aswan, while in Cairo can be increased from 31.1% to 38.6 %, and in Alexandria from 36.9% to 46 %. The research findings could be used by architects for thermal comfort improvement in residential buildings.

“…The building is located at the main University campus in Antiguo Cuscatlán, El Salvador. It is well documented that to reduce the operation energy demand of a building, both passive and active measures should be implemented, such as roof insulation, translucent skylights, and ventilation louvers, which effectively lower operation phase energy requirements; active measures include the use of lighting and an efficient air conditioning system [8,39,40]. The building structure consists of wood studs and beams, which allow for implementing materials with high thermal insulation levels.…”

“…Additionally, design tools [5] help guide the design teams on design decisions' practical and quantitative outcomes. Tools such as energy modeling and optimization software have become prevalent [6][7][8]. The design process of an NZEB generally includes energy modeling and optimization techniques to achieve the net zero energy balance within the design constraints.…”

Net zero energy building design methodologies include integrative approaches and numerical tools to provide optimal performance and cost-effective results. Team integration, characterized by knowledge transfer between disciplines, has yet to be quantified for the design processes of these buildings. This article proposes a specific methodology for designing net zero energy buildings, tested through a case study design process conducted in an academic setting at Universidad Centroamericana in El Salvador, with the participation of students and faculty members. Through a survey, interdisciplinary knowledge transfer between team members was measured. We found that, without additional instruction, team participants outperformed a control group without project involvement by 16.4% (P < 0.002, t-test) in terms of interdisciplinary knowledge. This result implies that designers acquire new knowledge from other disciplines by interacting and solving design problems, although such acquisition is not uniform between disciplines. Remarkably, results show that the disciplinary groups that acquired the most knowledge about each other are Mechanical Engineering students and Architecture students. These results help us understand how to improve the design process, limit boundaries for disciplinary interactions, and determine which specific knowledge gaps to target per discipline in engineering and architecture education.

“…It also contributes to global warming [5,6]; with relation to the greenhouse effect and the possibility of ozone depletion, there is significant CO2 released into the atmosphere because of the usage of conventional air conditioning systems [7]. The above problems can be overcome by thermoelectric air conditioning systems operated by solar photovoltaic panels (PV), which are environmentally friendly and more economical [8][9][10]. A thermoelectric cooling device instantly transforms electrical energy into thermal energy according to the Peltier effect [11][12].…”
