“…They are timber and concrete floors, pitched and flat roofs using hardwood, hollow heavy concrete, and adobe walls. In contradiction to the conventional studies where adobe and wood are mostly suggested building materials for the humid tropics, this study found that the indoors were more comfortable with hollow heavy concrete walls, concrete floors, and hardwood pitched roofs Cool roofs (reflective roofs with a high albedo and thermal emittance) seem to have more significant potential in terms of climate change adaptation along with energy efficiency, mitigating heat island effects, improving air quality and reducing heat wave impacts (Bureau of Energy Efficiency, 2011;Garg et al, 2016a;Garg et al, 2016b;Afshari, 2023;Bamdad, 2023). These roofs can be a better strategy in dealing with hotter environments, but further studies are required to understand their performance during winters when heating is the priority.…”

Buildings worldwide have evolved based on local resources and skills, evolving form and orientation to ensure a productive and comfortable indoor environment. Traditional habitations rely on passive climate-responsive mechanisms and physiological resilience. At the same time, contemporary buildings rely increasingly on active mechanisms for fine-tuned convenience and comfort. Those buildings are becoming less habitable due to climate change. This paper presents an overview of research into climate-responsive building adaptation, identifying various factors determining a building’s ability to regulate external climatic conditions in providing a habitable indoor environment. The review covers the ability of occupants to manage their thermal environment and adaptation mechanisms, including various adaptation strategies attributed to climate change. Besides a review of relevant research tools and methodologies, the paper also identifies future research challenges. Those challenges include but are not limited to evaluating climate classification provided by building standards given climate change, the need for region-specific climate-change vulnerability assessment of the built environment to develop specific adaptation strategies, a survey of vernacular structures to understand their inherent adaptation capacities, developing a framework to study building adaptation, etc. Thus, this review opens the possibility of further research in building adaptation.

“…Simultaneously, we note that in recent years, rooftop greening has been increasingly applied in urban renewal practices. Numerous studies indicate that rooftop greening has significant energy-saving potential [56]. As a nature-based solution, rooftop greening can serve as an effective tool for improving the urban heat environment, conserving energy, and addressing climate change [57].…”

With global warming and rapid urbanization, the microclimate in the Lingnan region is prone to health problems, such as pyrexia and infectious diseases, and the average annual number of heatwave-related deaths is rising rapidly. The large-scale regeneration of traditional neighborhoods in Lingnan under high-quality development is underway, which has implications for the thermal comfort of microclimatic environments. This study focused on the impact of different building unit types and spatial patterns on thermal comfort in the Donghuali traditional neighborhood of Foshan City as an example. We extracted eight basic morphological units and designed a prototype block of 400 m × 400 m. In the Rhinoceros & Grasshopper parametric software 6.7, a variety of plug-ins were integrated to establish a platform with parametric modeling, microclimate simulation and evaluation, and optimal design for thermal comfort. Through experiments, the effects of new single-type and new composite building units on thermal comfort were investigated, and the correlation equations between spatial morphology and microclimate comfort in Lingnan traditional neighborhoods were established. Finally, the multi-objective genetic optimization of thermal comfort was carried out as an example of real block renewal, which provides a practical reference for the planning and design of traditional blocks.

“…Displaying bus schedules could also encourage individuals to utilise the bus as a means of transportation. To enhance the green infrastructure as related to the external factors, we propose the introduction of nature-based solutions [51], including green walls [38], cool roofs [52] and green spaces throughout the campus, to support environmentally responsible behaviour [27]. The implementation of these interventions will foster pro-environmental behaviours, resulting in a greener, more sustainable campus environment.…”

The significant contribution of building materials and emissions, accounting for approximately 40%, underscores the crucial role that buildings play in addressing climate change. Considering that buildings and transport are among the main contributors of energy-related emissions, Bahrain’s greenhouse gas emissions (GHGs) increased from 16 (Mt/year) in 1990 to 54 (Mt/year) in 2020, which requires immediate attention. Pro-environmental behaviours play a significant role in reducing overall emissions and mitigating climate change. Therefore, this research aims to clarify the main factors influencing pro-environmental behaviour in the University of Bahrain campus, in order to create a strategic framework encompassing pro-environmental solutions working towards zero emissions. The problem is analysed through a mixed methodology based on a literature review, questionnaire and photographic analysis. The findings highlight the importance of several internal and external factors in relation to pro-environmental behaviour in higher education environments. The results provide valuable insights for stakeholders and decision-makers to implement change through green initiatives at a policy level.
