Industrial building renovation is a sustainable strategy to preserve urban heritage while meeting modern needs. However, how interior material scenes affect users’ emotions, thermal perception, and functional preferences remains underexplored in adaptive reuse contexts. This study used virtual reality (VR) to examine four common material scenes—wood, concrete, red brick, and white-painted surfaces—within industrial renovation settings. A total of 159 participants experienced four Lumion-rendered VR environments and rated them on thermal perception (visual warmth, thermal sensation, comfort), emotional response (arousal, pleasure, restoration), and functional preference. Data were analyzed using repeated measures ANOVA and Pearson correlation. Wood and red brick scenes were associated with warm visuals; wood scenes received the highest ratings for thermal comfort and pleasure, white-painted scenes for restoration and arousal, and concrete scenes, the lowest scores overall. Functional preferences varied by space: white-painted and concrete scenes were most preferred in study/work settings, wood in social spaces, wood and red brick in rest areas, and concrete in exhibition spaces. By isolating material variables in VR, this study offers a novel empirical approach and practical guidance for material selection in adaptive reuse to enhance user comfort, emotional well-being, and spatial functionality in industrial heritage renovations.

The design of composites offers extensive opportunities for controlling parameters and utilizing diverse materials, including those sourced from recycling or waste streams. In this study, biocomposites were developed using high-density polyethylene (HDPE) and pomace derived from oilseed plants such as evening primrose, gold of pleasure, rapeseed, and sunflower seeds, mixed in a 1:1 ratio. These biocomposites were evaluated for their structural, mechanical, morphological, and thermal properties, as well as their vulnerability to overgrowth by cellulolytic fungi. The results indicate that incorporating plant waste into HDPE reduces thermal stability while increasing water absorption and thickness swelling. Additionally, the biocomposites showed enhanced fungal growth, which may improve their biodegradability. Notably, the PE_EP composite, derived from evening primrose pomace, did not show significant differences in surface roughness and MOE parameters compared to pure polyethylene. In the case of PE_R composite, an increase in MOE was observed while maintaining the MOR parameter compared to pure PE. Although generally the mechanical properties of composites were lower compared to pure polyethylene, the findings suggest that with further optimization, oil plant pomace can be a valuable raw material for producing biocomposites suitable for various industrial applications, thereby contributing to sustainability and effective waste recycling.

It is important for engineering applications that we evaluate the thermal environment based on long-term tracking and investment. Methods merging environmental, physiological, and psychological domains to implement a human-centered approach were applied in this study to assess the outdoor thermal environment in a park. The constant influence of humans in the outdoor environment can change people’s physiological, psychological, and thermal responses. Additionally, the relationship between human physiological, psychological, and thermal factors was explored in this study. The results of this study provide the following findings: (1) In summer, subjects’ skin temperature increased by 0.35 to 2.83 °C during a one-hour outdoor test without shelter, while when tree shade was provided, subjects’ skin temperature dropped by 0.50 to 1.87 °C (except for motion segments). (2) In winter, if subjects stayed outdoors for 1 h, their body segments’ skin temperature dropped by a maximum of 7.93 °C. (3) When subjects went outside, in the early stage, their thermal responses fluctuated for a long time. Therefore, TSV, TCV, and TAV should be measured after they stay outdoors for 45 to 55 min in future studies. (4) Different body segments show different sensitivities to hot or cold. Considering this, a new group of formulas for mean skin temperature calculation are proposed with high accuracy (winter: 0.95; summer: 0.89). (5) Data for the one-hour change in different assessment indicators provide a good viewpoint for park design considering multiple aims such as comfort (TCV), pleasure (EVI), and increasing energy (PFI). Overall, this study took Stalin Waterfront Park as a case study, and some suggestions involving landscaping nodes, space types, and facilities are offered. Moreover, this study provides a novel theory and reasonable method that can be referred to in urban planning and landscape design. Full article

The waterfront park in northern China always has two parallel leisure pathways, a sunshine pathway and a tree-shaded pathway, which is attributed to the seasonal variations in water level. To provide some design suggestions according to the local characteristics of the waterfront park in northern China, this study selected six young volunteers to take part in an outdoor field experiment and a questionnaire survey in Stalin Park of Songhua River in Harbin, China. During the experiment, the volunteers’ local skin temperature and core temperature were recorded, with their subjective responses recorded every 5 min, including thermal comfort, thermal sensation, thermal pleasure, and fatigue scale vote. This study found that, compared with the sunshine pathway, the tree-shaded pathway not only optimized people’s outdoor thermal comfort and thermal pleasure, but also improved their fatigue scale vote experience. Some evidence showed that people’s subjective response to the outdoor thermal environment might be influenced by physical factors (temperature, velocity, humidity, radiation, etc.) and may also be influenced by the surrounding landscape view (water, square, lawn, tree, etc.). The first piece of evidence is that, during the first 10 min, people’s thermal sensation in the sunshine pathway group was high, but they kept voting for high thermal comfort, which may be due to the influence of the waterfront view on people’s subjective response to thermal comfort. The second piece of evidence shows that people’s overall thermal sensation was calculated by their local thermal sensation, looking at former research, with the voting results very different to the calculated results, which could be attributed to the influence of diversity landscape elements on people’s subjective response to thermal sensation. Based on these results, some suggestions for the leisure pathway design along Stalin Park of Songhua River in Harbin, China, were given. The shaded device of the sunshine pathway should be designed in 15-min-walk intervals and accessible ways to the tree-shaded pathway should be added. The other facilities should be designed with 30 min walking distance on the tree-shaded pathway and 20 min walking distance to the sunshine pathway. Diversified landscapes should be designed for both the tree-shaded pathway and sunshine pathway, which could improve people’s outdoor thermal comfort and the general subjective response to the environment. It is worth noting that the sample size of this study was small (6), and the participants were all homogenous young people (age, height, weight); thus, this study could be considered a preliminary work and the results and applicability have limitations.

This review analyzes the main anatomical structures and neural pathways that allow the generation of autonomous and behavioral mechanisms that regulate body heat in mammals. The study of the hypothalamic neuromodulation of thermoregulation offers broad areas of opportunity with practical applications that are currently being strengthened by the availability of efficacious tools like infrared thermography (IRT). These areas could include the following: understanding the effect of climate change on behavior and productivity; analyzing the effects of exercise on animals involved in sporting activities; identifying the microvascular changes that occur in response to fear, pleasure, pain, and other situations that induce stress in animals; and examining thermoregulating behaviors. This research could contribute substantially to understanding the drastic modification of environments that have severe consequences for animals, such as loss of appetite, low productivity, neonatal hypothermia, and thermal shock, among others. Current knowledge of these physiological processes and complex anatomical structures, like the nervous systems and their close relation to mechanisms of thermoregulation, is still limited. The results of studies in fields like evolutionary neuroscience of thermoregulation show that we cannot yet objectively explain even processes that on the surface seem simple, including behavioral changes and the pathways and connections that trigger mechanisms like vasodilatation and panting. In addition, there is a need to clarify the connection between emotions and thermoregulation that increases the chances of survival of some organisms. An increasingly precise understanding of thermoregulation will allow us to design and apply practical methods in fields like animal science and clinical medicine without compromising levels of animal welfare. The results obtained should not only increase the chances of survival but also improve quality of life and animal production. Full article
