Rising global temperatures and more frequent heatwaves due to climate change have led a growing body of research increased policy focus on how protect against the adverse effects heat. In cold temperate Europe, dwellings traditionally been designed for protection rather than heat mitigation. There is, therefore, need understand mechanisms through which indoor overheating can occur, its occupants energy consumption, we design, adapt, operate buildings during warm weather improve thermal comfort reduce cooling consumption. This paper brings together experts in from across Europe explore 10 key questions about causes risks residential settings Central Northern including way define measure overheating, impacts, social implications. The is not summarising literature, but identifying evidence, challenges misconceptions, limitations current knowledge. Looking ahead, outline actions needed (re)design dwellings, neighbourhoods, population responses heat, potential shape these actions. doing so, illustrate adaptation multi-faceted challenge that requires urgent coordinated action at multiple levels, with feasible solutions clear benefits health energy.

Thermal comfort and energy efficiency evaluation of a novel conductive-radiative Personal Comfort System

Building and Environment, Journal Year: 2023, Volume and Issue: 244, P. 110787 - 110787

Personal Comfort Systems (PCSs) create a localized comfort situation satisfying individual needs. These devices have low power consumption, as they focus on local environment and thus reduce the energy consumption of main HVAC systems by extending ambient control setpoint ranges. This study focuses assessing new type PCS: warming desk. It uses two most efficient effective means heat transfer for person: conduction (hands) radiation (lower upper body parts facing table). Two different desks were tested, both simultaneously heating upward downward with surface temperatures, one higher temperature upward. The tested 30 subjects, inside climatic chamber, kept at 17 °C air temperature. Both are capable generating good overall (whole-body) thermal sensation, even leaning towards slightly warm someone. Moreover, results showed that PCS based direct contact skin should be below 36°, while can reach temperatures: personal is critical, not everyone preferred same operative "correct" toward neutral sensation about 7K, creating improved compared to centralized HVAC. In its current design, required 170W, significantly lower than 500/1500W common portable electric heater. expected in an optimized could reduced further 30/40W.

A systematic review of Personal Comfort Systems from a post-phenomenological view

Ergonomics, Journal Year: 2024, Volume and Issue: unknown, P. 1 - 24

Published: Feb. 6, 2024

Personal Comfort Systems (PCS) are equipments that heat and/or cool occupants without affecting surrounding environments, ranging from commonly used devices to innovative technologies, and tend be controlled by people. These systems aim address energy consumption occupant satisfaction issues related centralised air-conditioning. Although there systematic studies on these systems, is a lack of documentation regarding mediation characteristics between people the built environment. This article presents review PCS using search academic literature patents, classifying based thermal categories device typologies while introducing post-phenomenological categories. The results show most fall into 'Heating' 'Cooling ventilation'. also view territory attributes technological complexity. Finally, PCS' discussed concepts Embodiment, Hermeneutic, Background providing insights for future research opportunities development.
