“…This is further illustrated by the story of an academic in New York who complained about 'over-cooling' in her office and was provided with a heater by the facilities manager. While the culture of fossil fuel profligacy must be challenged, it may also be the case that individual 'tailoring' of our thermal environments and personal control systems may be valid and indeed promote energy efficiency (Tang et al 2022).…”

Far from being a panacea, air-conditioning is shown to create social, environmental and economic problems. Alternatives to air-conditioning are identified as a key means of reducing energy demand and carbon emissions, improving resilience to heat, and providing a healthy indoor environment. These alternatives are more than a technological issue and help to reframe coolth as an attribute and not a commodity. This editorial introduces the themes and individual papers in this special issue. It explores the implications of these alternative solutions across a range of issues: health and wellbeing; air quality; heat stress; technical/design solutions; economics and equity; climate change; social expectations and practices; policy and regulation; supply chain and procurement; education and training. Recommendations for change involve policy and regulation, construction industry business models, redefining the design decision process, improving performance and feedback, and updating workforce skills and capabilities.

Noise, vibration, and harshness (NVH) researchers spend inexhaustible resources of materials, time and money in determining the objective factors that are important in ensuring acoustic comfort in vehicles. In this paper, the factors that directly influence the interior acoustic pressure level in a heavy-duty vehicle were investigated. It was determined using specific descriptors and different units of measurement in assessment of sound levels and the impact generated by noise, the level of interior acoustic pressure and particular values of some prominent sources of noise in the operation of vehicles (engine, HVAC system), taking into account the factors of insurance and thermal comfort, with the aim of determining the cumulative impact at the board of heavy vehicles due to noise.

“…Inspired by the fact that local thermal sensations could greatly affect overall thermal sensation and comfort, more and more scholars have considered using personal comfort systems (PCS) for human thermal regulation while helping to save building energy consumption [28]. A large number of experiments on the application of various kinds of PCSs have been conducted [29]. A heated/cooled chair was used to condition the microclimate around the back and hips [30,31]; a heated vest was used to heat the torso [32,33]; a heating mat and foot-warmers were used to warm up feet [34,35]; and the face and chest were cooled by deck fans [36].…”

“…However, the design of existing PCS products was not effectively guided by obtained local thermal comfort results, and related experiments were more often based on existing products rather than on conclusions drawn from previous research. Furthermore, the most effective targeted body parts and heat transfer mechanisms for PCSs remain undetermined [29]. Therefore, conducting local thermal sensation experiments can not only contribute to a greater understanding of local thermal sensation mechanisms and their effect on overall thermal comfort, but also provide guidance for PCS product design and related research.…”

The thermal perception of different body parts can vary greatly throughout the human body and have different influences on overall thermal sensation and comfort. Various personal comfort systems (PCS) have been developed to stimulate local body parts for the purpose of enhancing human thermal comfort, yet the most effective body parts for intervention remain undetermined. Therefore, a series of climate chamber experiments under five uniform environments with three sets of suits were conducted in this study. The results showed that the head, chest, belly, and hands tended to feel no cooler than overall in cooler environments, but arms and legs felt generally no warmer than overall in warmer environments. The head, trunk and upper arms were more likely to be the comfort-dominant body parts. Additionally, the upper arms and upper back expected temperature regulation measures the most under non-neutral environments, thus they seem to be the two most needed and effective targeted body parts that a PCS could be applied to. The skin temperature and thermal sensation of limbs were more sensitive to indoor air temperatures than those of the torso. However, variations in the skin temperature of the head, chest, upper back, and calves had the strongest correlation with overall sensation vote changes. The above results and conclusions can not only serve as the basis for the future studies of local thermal comfort, but also provide theoretical guidance for the design of future PCS products.
