Bio‐Inspired Multifunctional Smart Windows: Surface Wrinkle‐Crack for Dynamic Optical and Wettability Modulations

open access: yesAdvanced Optical Materials, EarlyView.
This work presents a composite material for smart windows, combining W‐doped VO2, SiO2 nanospheres, and PDMS elastomers. The material simultaneously offers energy savings and on‐demand privacy at low temperatures. The research provides an insight to the role of surface wrinkles in enhancing privacy and introduces potential self‐cleaning features ...

Performance and Thermal Comfort [PDF]

open access: possibleErgonomics, 1971
This experiment attempts to establish an objective measure of thermal comfort. A theoretical explanation of the relationship between performance and comfort is given and is represented in terms of an hypothesis. A total of 50 subjects was divided among five groups, each group experiencing one temperature in the range 15.6-26.7°C (60-80°F) for both air ...

Thermal comfort

2018
The processes of thermoregulation are roughly divided into two categories: autonomic and behavioral. Behavioral thermoregulation alone does not have the capacity to regulate core temperature, as autonomic thermoregulation. However, behavioral thermoregulation is often utilized to maintain core temperature in a normal environment and is critical for ...

Dynamic thermal environment and thermal comfort

Indoor Air, 2015
Research has shown that a stable thermal environment with tight temperature control cannot bring occupants more thermal comfort. Instead, such an environment will incur higher energy costs and produce greater CO2 emissions. Furthermore, this may lead to the degeneration of occupants' inherent ability to combat thermal stress, thereby weakening thermal ...

Thermal Stress and Thermal Comfort

Ergonomics, 1973
The factors which determine the level of heat stress and the difficulties inherent in its measurement are discussed. The degree of thermal comfort or discomfort is shown to he a useful measure of thermal stress and methods for the determination of the preferred temperature are described.

The Thermal Comfort of Sedentary Workers [PDF]

open access: possibleAsia Pacific Journal of Public Health, 1987
Two hundred and eighty-five Office workers were surveyed and the micro-climatic conditions in which they worked were measured to evaluate their preferred temperature. About 78% of workers considered the natural tropical climate uncomfortable. However, 76% to 87% of workers in airconditioned Offices approved of their thermal environment if its ...

A guide to thermal comfort

Applied Ergonomics, 1973
This guide provides a simple design procedure for dealing with the requirements for a comfortable thermal environment. From the expected activity level and clothing insulation of the people concerned, a subjective temperature is calculated which will provide thermal comfort.

Thermal Comfort in Nurseries

Indoor Air, 1995
The mean skin temperatures as well as the temperatures of the hands, feet and forehead of small children were measured in nurseries at air temperatures of 20 degrees C and 22 degrees C. Differences were studied between babies remaining still, babies crawling on tiling, wooden floors or rubber foam groundsheets and older walking children.

THERMAL COMFORT IN THE HOME

Journal of Consumer Studies & Home Economics, 1980
The thermal conditions required for comfort in the indoor environment have stimulated much research. Results of this research have both elucidated the physiological mechanisms which determine what conditions are comfortable as well as defining the combinations of physical variables which constitute these.

Thermal comfort

2006
Publisher Summary Thermal comfort is primarily controlled by a building's heating, ventilating, and air-conditioning systems, though the architectural design of the building may also have significant influences on thermal comfort. This chapter discusses the seven factors that influence thermal comfort and why thermal comfort depends on the individual ...
