Abstract This study aims to explore how traditional buildings of Indonesia adapted and responded to the current climate. Scientific publications regarding traditional houses from various regions in Indonesia were gathered to be examined the locality values in thermal comfort. The examination of the scientific publications highlighted some housing elements and arrangements that influence the thermal comfort of the houses. The building elements that affect the thermal comfort encompass lifted house on stilts; appropriate size and amount of windows; ventilated roof; selected natural material; divider arrangement; and the existence of veranda. Furthermore, as exemplified in Bali, the proper spatial arrangement between house buildings and open space influences traditional Indonesian houses’ thermal comfort. In conclusion, dealing with climate in a tropical area with high humidity can be demonstrated in those locality values without consuming excess energy for a cooling system. The significance of this study is beneficial for the development of tropical houses, which is expectedly to consider those locality values.

Abstract It is obvious that an increase in the built environment in many major cities is not balanced with the availability of green open space causing environmental problems such as an increase in accumulative city temperature (e.g., urban heat island). Therefore, many initiatives have been implemented to integrate more green open spaces in an effort to deal with increasing air temperatures in cities, but baseline information on the positive impact on the built environment is still lacking. The objective of this study was to identify thermal comfort in green open spaces and built environments in a central business district. Basic microclimate variables and thermal humidity index (THI) were analyzed in three sites representing the district by also considering the distribution of green open spaces, buildings, and traffics. Results showed that in the morning, the average temperature at the three sampling points have a low temperature (T=27.77-28.50°C) with high humidity (RH=77.21-80.97%) and the THI value is quite comfortable (THI=26.72-27.22°C), while during the daytime, the temperature conditions at the three sites have high temperatures (T=31.37-33.04°C) with low humidity (RH=63.30-65.80%) and high THI values (THI=29.22-30.62°C). In the afternoon, the temperature conditions at the three sample points have a high enough temperature (T=29.70-30.61°C) and high humidity (RH=67.36-71.02%), while the THI value is only in point two, which is close to the quite comfortable category (THI=27.98°C), while other locations have a value THI=28.60°C and 28.62°C. The results of this study mark the presence of green open space with the trees in the district has a positive effect on decreasing air temperature and hence increasing environmental comfort. The addition and enrichment of trees can be done to increase thermal comfort in the built environment.

The world has not been able to achieve minimum greenhouse gas emissions in buildings’ energy consumptions because the energy and emissions optimization techniques have not been fully utilized. Thermal comfort is one of the most important issues for both residential and commercial buildings. Out of the 40% of global energy consumed by buildings, a large fraction is used to maintain their thermal comfort. In this study, a comprehensive review of the recent advancements in building energy conservation and efficiency application is presented based on existing high-quality research papers. Additionally, the retrofit of the heating/cooling and hot water system for an entire community in Cyprus is presented. This study aims to analyze the technical and environmental benefits of replacing existing electric heaters for hot water with heat pump water heating systems and the use of heat pump air conditioners for thermal comfort in place of the existing ordinary air conditioners for space heating and cooling. One administrative building, 86 apartments (including residential and commercial) buildings, and a restaurant building is retrofitted, and the feasibility of the project is determined based on three economic indicators, namely; simple payback period (SPP), internal rate of return (IRR), and net present value (NPV). The electrical energy required by the hot water systems and the heating/cooling system is reduced by 263,564 kWh/yr and 144,825 kWh/yr, respectively. Additionally, the retrofit project will reduce Cyprus’ CO2 emission by 121,592.8 kg yearly. The SPP, IRR, and NPV for the project show that the retrofit is economically feasible.

In a field test of a hybrid desiccant cooling system (HDCS) linked to a gas engine cogeneration system (the latter system is hereafter referred to as the combined heat and power (CHP) system), in the cooling operation mode, the exhaust heat remained and the latent heat removal was insufficient. In this study, the performance of an HDCS was simulated at a humidity ratio of 10 g/kg in conditioned spaces and for an increasing dehumidification capacity of the desiccant rotor. Simulation models of the HDCS linked to the CHP system were based on a transient system simulation tool (TRNSYS). Furthermore, TRNBuild (the TRNSYS Building Model) was used to simulate the three-dimensional structure of cooling spaces and solar lighting conditions. According to the simulation results, when the desiccant capacity increased, the thermal comfort conditions in all three conditioned spaces were sufficiently good. The higher the ambient temperature, the higher the evaporative cooling performance was. The variation in the regeneration heat with the outdoor conditions was the most dominant factor that determined the coefficient of performance (COP). Therefore, the COP was higher under high temperature and dry conditions, resulting in less regeneration heat being required. According to the prediction results, when the dehumidification capacity is sufficiently increased for using more exhaust heat, the overall efficiency of the CHP can be increased while ensuring suitable thermal comfort conditions in the cooling space.

The thermal environment is one of the main factors that influence thermal comfort and, consequently, the productivity of occupants inside buildings. Throughout the years, research has described the connection between thermal comfort and productivity. Mathematical models have been established in the attempt to predict changes in productivity according to thermal variations in the environment. Some of these models have failed for a number of reasons, including the understanding of the effect that several environment variables have had on performance. From this context, a systematic literature review was carried out with the aim of verifying the connection between thermal comfort and productivity and the combinations of different thermal and personal factors that can have an effect on productivity. A hundred and twenty-eight articles were found which show a connection between productivity and some thermal comfort variables. By means of specific inclusion and exclusion criteria, 60 articles were selected for a final analysis. The main conclusions found in this study were: (i) the vast majority of research uses subjective measures and/or a combination of methods to evaluate productivity; (ii) performance/productivity can be attained within an ampler temperature range; (iii) few studies present ways of calculating productivity.

Social mobility is one of the concepts which is the most intrinsically bound to sociology. Hence, the diachronic analysis of this concept contributes to our understanding of sociology and the way that the discipline has changed, as it turned to individual social trajectories according to different topics. Aimed at contributing to this understanding, I’ve developed a literature review based on a systematic collection of the scientific publications in social sciences directly addressing social mobility. A database with conceptual and methodological variables was compiled (N=1054) and worked on. Distinct periods in the life course of this concept have been identified, with the emergence of a scattered concept (1920–1959), the golden age of social mobility (1960–1989), followed by a period of fragmentation and resistance (1990–2012). These three periods are characterized by different methodological and geographical hegemonies, flows and volumes of publications, and also by different tendencies and theoretical and disciplinary rivalries.

The role of a forest sector in the transition to a circular economy (CE) is critical. Therefore, the purpose of this study is to summarize the main findings of the most important published articles and to provide insights on the interdisciplinary space at the interface of concepts related to a forest-based CE. Moreover, it attempts to assess the challenges raised from adopting the CE in forest sector. Through a systematic literature review, 69 scientific publications were selected and evaluated by two sights: (i) a descriptive analysis and (ii) a cluster analysis of the keywords related to the forest-based CE. The study highlights the need for additional survey on optimizing the interaction between forest ecosystem services and circular economy. Further discussion is also needed about the relations of the key factors associated with the forest-based circular economy, as they emerged from the cluster analysis and the co-occurrence network map.

Aim:The objective of this article is to identify and analyze what is known about characteristics in and around the home that support well-being for those with cognitive impairment. This could provide direction for designers of homes in general, but specifically for designers trying to meet the needs of people with cognitive impairment.Background:It has been established that there is a relationship between psychological well-being and a person’s environment. Research also shows that particular design aspects can reduce the impact of cognitive impairment. However, there is limited design expertise in the Australian housing market to create supportive spaces which will help to reduce the impact of the disability for those with cognitive impairment.Method:A literature review was carried out to determine the extent and details of what is known about the relationship of home design and its impact on emotional, psychological, or social well-being for people with cognitive impairment.Conclusions:The study indicates that researchers in various disciplines understand that pragmatic design inputs such as thermal comfort and adequate lighting are important for people with cognitive impairment. In addition, some researchers have shown or surmise that there are other “intangible” designer-controlled elements that have beneficial impacts on people with cognitive impairment. Details of these intangible elements are sparse, and how much they might improve the quality of life for a person with cognitive impairment is not well understood. Further research is required to meet a growing need.
