Special Issue Information

Dear Colleagues,

Populations are growing globally, especially in cities, and particularly in the hot-climate regions such as in Asia and Africa.  Energy consumption has been increasing rapidly in line with the economic growth in these regions. Urban populations experience an accelerated warming due to the combination of global warming and urban heat islands. Appropriate energy-saving cooling techniques are therefore in high demand in order for sustainable buildings and cities to be realized, especially in rapidly growing regions. This Special Issue invites papers which address the latest techniques/technologies for cooling buildings and cities which contribute to the realization of sustainable societies in hot or warm regions. Innovative cooling techniques/technologies are in demand for various strata of income groups. We therefore expect a wide range of techniques/technologies in terms of the cost and affordability, including not only passive cooling techniques but also active/hybrid cooling technologies. Furthermore, cooling techniques/technologies should cover not only a human scale but a building scale and be further applicable to a city scale. It would also be interesting to review traditional techniques incorporated into so-called vernacular buildings. We invite the submission of original articles, case studies as well as review papers from various regions. This Special Issue will contribute to the further accumulation of knowledge, especially focusing on cooling techniques/technologies for hot or warm regions towards sustainable societies.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sustainability is an international peer-reviewed open access semimonthly journal published by MDPI.

Indonesian urban population increase has led to increased energy demands and housing inventory shortages. The Ministry of Public Works and Housing (PUPR) supplies collective housing for low-income communities (MBR). The development of low-carbon collective housing has been thought to suppress the abrupt increase in household-sector energy demand and lead to mitigated greenhouse gas (GHG) emissions. In tropical climates, it is essential to reduce the dependence on air conditioners (AC) to suppress energy consumption. Therefore, to investigate the relationship between cooling methods and energy consumption, this study surveyed the energy consumption per household and classified the existing cooling patterns of ACs, fans, and window openings in collective housing with different income groups in Indonesia. The results confirmed that the use of AC increases household energy consumption. Meanwhile, the implementation of natural ventilation (NV) showed significantly lower energy consumption with a high thermal satisfaction of more than 80% during the day and 90% at night; thus, both energy consumption reduction and indoor thermal comfort improvement could be achieved through these methods. The findings of this study serve as a starting point for verifying the energy saving effects of air conditioning habits with the consideration of socio-demographic changes for the purpose of decarbonizing collective housing, including future predictions and energy simulations.

The number of scientific papers has dramatically increased in recent years; however, such a huge number of papers often become difficult to review qualitatively because of limited time and cost. A text-mining-based bibliometric analysis method is developed to provide a comprehensive overview of passive cooling methods used in buildings in hot and humid climates. First, a comprehensive overview analysis is conducted to clarify the trends in studies on passive cooling methods between 1970 and 2022, using 39,604 publications. Second, 15 coding rules are constructed to perform a detailed analysis, and possible combinations of passive cooling methods are discussed. The detailed analysis of the co-occurrence network based on the comprehensive overview and 15 coding rules shows that the recent studies on thermal energy storage have mainly focused on phase change material (PCM), which is a latent heat storage material, rather than sensible heat storage materials such as concrete. The analysis of the co-occurrence network indicates that natural ventilation maintains the vital role of passive cooling methods by improving thermal comfort in hot climates. The constructed method and possible combinations of passive cooling methods for hot and humid climates will help engineers find effective combinations in the planning stage. Full article
