“…From this investigation, beneficial effects of double-glazing of the window panes as the most effective solar radiation penetration control strategy (through the openings), followed by integration of fixed sun shading elements on the exterior parts of the building are established. These research outputs align with the findings of [7], [12], [17], [24], [25], [36], [37], among others. It is therefore advised that adoption of double or more layers of glass panes in controlling indoor solar radiation penetration should be encouraged.…”

Tropical region is characterised by high outdoor solar radiation and temperature. These radiations penetrate into the interior particularly through the window glazing, thereby raising the indoor temperature with a resultant effect on high cooling energy demand (for comfortable indoor living condition). Of the identified three sustainable approaches towards inhibiting direct incoming indoor solar penetration in the tropical city of Ogbomoso, Nigeria, this study, through computer-based simulation technique, compared performance effectiveness of varying design interventions on the window composition/material adopted. Through multiple/iterative building performance simulation tool, DesignBuilder, the methodology involves virtual model of a three-bedroom residential building, typical of the prevailing building typology in the study area. This particular model served as the experimental control model. Three (3) variants of the control model, each with either externally mounted shading devices on the building envelope, or improved thermally resistant multilayer window glazing (i.e., double glazing) or low-emissivity coated window glazing material, were generated for individual performance effectiveness evaluation. All the four models were subjected to a twelve-month simulation cycle, to experience a year-round thermal conditions and evaluations individually. The results show that double-glazing window installation proved to be the most effective approach, with about 13.1 % improvement (i.e., solar radiation inhibition) on the indoor thermal gains. This is followed by the externally mounted shading devices (i.e., 11.1 % improvement) and the least inhibition (i.e., 5.0 %) was observed in the case of low-emissivity coated window glazing material. Adoption of double or more layers of glass panes in window fabrication for controlling indoor solar radiation penetration is therefore advised. Alternatively, integration of external window shading elements could be adopted. This study is directed towards reduction of cooling energy consumption in tropical buildings through efficient and sustainable indoor cooling mechanism capable of inhibiting solar gains into the building, with a focus on the performance roles and composition of windows in particular.

Climate change poses critical challenges for Qatar’s energy-intensive residential building sector. This study evaluates the impact of projected climate warming on optimizing rooftop solar photovoltaics (PV) for villas. An integrated modelling approach is employed, combining building energy simulation, PV system optimization, and performance assessment under varying climate scenarios. A typical Qatari villa is modelled in DesignBuilder and simulated under the baseline (2002) conditions and the projected years 2016, 2050, and 2100, reflecting incremental warming. Results show the villa’s annual electricity consumption will grow 22% by 2100, with summer peaks escalating to 26% driven by surging cooling demands. Techno-economic optimization in HOMER Pro (version 3.10) verifies a grid-connected rooftop PV system as optimal in all years, with capacity expanding from 7.4 kW to 8.2 kW between 2002 and 2100 to meet rising air conditioning loads. However, as temperatures increase, PV’s energy contribution declines slightly from 18% to 16% due to climate change degrading solar yields. Nonetheless, the modelled PV system maintains strong financial viability, achieving 5–8 years of paybacks across scenarios. This analysis provides empirical evidence of distributed PV’s effectiveness for Qatar’s households amidst escalating cooling consumption. However, maintaining solar mitigation potential requires evolving PV sizing methodologies and incentives to account for declining panel productivity at the country’s peak temperatures exceeding 50 °C. Overall, this study’s integrated framework evaluates residential solar PV systems’ capabilities and appropriate policy evolution under projected climate impacts for the first time in Qatar. The modelling approach and conclusions can inform building codes and pro-solar policies to accelerate adoption for emissions reduction. With villas representing over 100,000 units in Qatar, widespread rooftop PV integration can meaningfully contribute to national sustainability targets if implementation barriers are addressed considering climate change effects.

“…This ensures ease of comprehensive simulation process. DesignBuilder uses construction components to model the conduction of heat through walls, windows, roofs, ground and other opaque parts of the building envelope as the physical properties of each element have been pre-defined for broad simulation processes (DesignBuilder 2023;Abdullah et al, 2022…”

High solar gains associated with the Tropical climate result in high indoor temperature, the consequence of which induces indoor thermal discomfort. Particularly, both the East and West facing component building envelope receive more solar gains through early morning sun rise and late afternoon sun set respectively, thereby raising the indoor temperature of the affected spaces within the periods. However, the need to optimize indoor thermal comfort through mechanical installations among others, increases carbon emissions into the atmosphere, as buildings account for about 40% of global emissions through their construction, operation and maintenance. Due to its importance at the global level, Climate Change induced mitigation has resulted into promulgation of seventeen-pronged (17) United Nation’s Sustainable Development Goal 2030 (SDG-2030) Agenda. Of particular relevance within the precinct of built environment is the Agenda thirteen (Agenda-13) which encompasses the need for urgent action to combat Climate Change and its impacts across various areas of human engagements. It is on this basis that this research work explored beneficial impacts of selective treatment of East and West-facing residential building window fabrics, in the tropical city of Ogbomoso, Nigeria. In its approach, comparative evaluations of indoor solar gains using single-glazed and double-glazed virtual building models was carried out through DesignBuilder based simulations. The results indicate 8.5%, 8.5% and 8.6% annual reductions in the indoor solar gains in the whole building, East-end apartment and West-end apartment respectively, with the adoption of the double-glazed windows. Focusing specific individual sun-facing functional spaces (bedrooms in this case), more significant reduction in the indoor solar gains (i.e., about 28%) was recorded in each case. This research output may influence subsequent design and composition of the sun-facing window fabrics at this local level, thereby leading to reduced mechanical installations, for optimum indoor thermal comfort. This is an attempt to contribute towards achieving SDG-2030 Agenda-13 individually at this level, for overall collective realization at the global level. This endeavour aims at reducing carbon emissions at the building micro level in the study area, for overall clean, safe and sustainable global environment. This submission is part of an ongoing research work scheduled to be validated with life prototype/physical models subsequently.
