“…By identifying the barriers to passive design construction, this research aims to improve the overall success rate of construction projects in Pakistan. Figure 2 shows the stages of the analysis used in this research; it was adapted from the works [11,12]. Previous research was conducted to determine what factors could be holding back the widespread use of passive design.…”

To maximize profits without sacrificing quality, the concept of sustainable construction must be adopted across a project’s whole lifespan. Although adopting the idea of passive design in developing countries is incomplete, these studies have focused on the reasons for doing so. In contrast, there is limited evidence to completely analyze the influence of integrating passive design on the project sustainable success (PSS) of projects throughout their existence. This study focuses on the hurdles to passive design adoption in Pakistani building projects. It evaluates the impact of overcoming passive design (PD) adoption barriers on project sustainability success (PSS) during the duration of the project. Therefore, a more comprehensive literature assessment is required for conceptual model construction. Using a survey assessment instrument, Structural Equation Modeling (SEM) was constructed (i.e., a questionnaire). A total of 156 construction experts in Pakistan provided information. The result of the model demonstrated that the elimination of PD implementation obstacles had a moderate to high impact on PSS throughout the building structure’s lifetime. These results provide the foundation for legislation in a number of Asian nations about the efficient completion of projects via the removal of obstacles for the use of passive design. Similarly, the adoption of passive design will increase the success of the construction project.

“…Thus, metamodels to analyse the thermal performance of SH through sun orientation, shading and envelope materials, and natural ventilation models may provide thermal comfort options and should be applied during the early stages of the design process (Krüger;Laroca, 2010;Krüger, 2015;Rossi et al, 2019;Nunes et al, 2020). The public policies for SH in Brazil have included domestic Solar Water Heaters (DSWH) Lamberts, 2016).…”

Abstrac Social Housing (SH) is investigated worldwide, especially in emerging economies. However, SH literature demonstrates that there are still barriers to achieving the real benefits of those programmes. Brazilian SH programmes have positively reduced housing deficits and the vulnerability of low-income populations. However, studies developed in Brazil also reveal the negative impacts of SH. Investigating the reason for the recurrence of negative impacts is fundamental to gaining a stronger understanding of the causes and scope of SH problems. Moreover, state-of-the-art studies may support the development of actions to mitigate those problems. Thus, this study aims to categorise the major topics studied on SHs, identify and evaluate SH main failures and impacts, analyse intersections of topics, and understand their scope. A systematic review and literature mapping were applied to analyse SH studies. Although evidence emphasises significant advances in SH production, results demonstrate the intersecting panorama of occurrences that cause negative impacts and stress the need for investments and the implementation of housing public policies aligned with societal interests to improve SH.

China's building energy consumption accounts for 27.5% of China's total energy demand. This amount is increasing because of the considerable increase in the rate of household equipment mostly in air-conditioning systems. In this study, the TRNSYS simulation tool and improved Battle Royal optimizer (IBRO) is coupled for energy optimization of the building based on the simulation to study the impact of the overhangs optimization. The thermal comfort enhancement is evaluated in three case studies of three different weather conditions in China. To validate the achieved results, a comparison of the optimum values with benchmark cases is performed with consideration of heating and cooling demands, and yearly discomfort percentage. According to the achievements, an improvement can be seen in the comfort level. Also, the cooling demand is decreased by 4.2% for Shanghai. K E Y W O R D Sadaptive model, thermal comfort, improved Battle Royal optimizer, simulation-based optimization, thermal comfort, TRNSYS INTRODUCTIONBuildings use more than 30% of the overall energy demand worldwide, with estimates for increases in this portion because of urbanization, changes in weather conditions, and further living comfort standards. 1 In China, the rate of urbanization has been increased from 37.7% to 55.0% from the year 2001 to 2014. 2 Generally, the building's energy consumption is defined by the behavior of occupants, size of the building, climate, interior environment, building performance, building envelope, and service systems of the building. 3 Designing energy-effective buildings is essential. For achieving energy-savings in buildings, energy-effective strategies can be performed. [4][5][6] The equipment rate in heating and cooling devices is multiplying, then, the consumption of energy for heating and cooling is increasing. [7][8][9][10][11][12] Application of outer shading devices can be an efficient policy to decrease the cooling demand because it can keep the building from overheating from the solar resource through fenestrations in hot weather conditions. 13 Different papers have studied the shading devices' impact on enhancing the thermal operation and the comfort level of occupants in the literature. For example, in Reference 14, the impact of shading devices on the occupants' thermal comfort in a cross-ventilated office case for altering interior airflow speeds in hot seasons has been studied. The results indicated that the element placed on the façade and geometry are two important factors that affect the performance of shading devices on the occupants' thermal comfort.In Reference 15, a BIM-based technique has been proposed to give an automatic evaluation of the envelopes OTTVs of an office building. In this paper, developed visual scripting and BIM are integrated to obtain physical and thermal properties to confirm the calculation of thermal transfer amount. 16 This system gives a useful decision support system for decision-makers 17 to choose a proper material of envelope to obtain an optimal OTTV to optimize the en...
