The present work is focused on the control of indoor thermal comfort in buildings equipped with HVAC (Heating, Ventilation and Air Conditioning) systems. The occupants’ thermal comfort sensation is addressed here by the well-known comfort index (PMV Predicted Mean Vote). In this context, different strategies for the control algorithms are proposed by using only-one-actuator system that can be a...

UNLABELLED Environmental conditions such as lighting and thermal comfort are influencing factors on sleep quality and visual tiredness. The purpose of this study was the determination of the relationship between thermal comfort and light intensity with the sleep quality and eye fatigue in shift nurses. METHOD This cross-sectional research was conducted on 82 shift-work personnel of 18 nursing...

Attractive public open spaces can serve as key design elements for enhancing life quality in urban areas and to diminish the negative effects of urbanisation. In order to fulfil this task, open spaces must meet the expectation of potential users and offer the right mix of environmental, economic and social conditions. It is well known that the local microclimate belongs to the main factors driv...

Localized HVAC systems with the task-ambient conditioning concept represent a promising option towards energy-saving in buildings. The design of such systems needs to involve evaluation of the local thermal comfort that corresponds to different body segments. In this work, an experimental technique using a thermal manikin was developed to determine the optimum configuration(s) among different v...

This paper discusses the link between thermal comfort and productivity of office workers and presents some limited conclusions from a European field study of office buildings. The importance of productivity measurement and current methodologies of measurement are discussed and shortcomings highlighted. The paper concludes with an introduction to a new technology developed in Japan that may prov...

The aim of this study is to present a thermal human bioclimate analysis of Hungary by means of mapping, useing multiple linear regressions. The present study links geographical information with climatological data in order to generate a spatial distribution of PET values of a region. The distribution of average PET values of seasons are drawn at 1 km resolution. Meteorological data used to draw...

Human’s disregard to nature and consequently his living environment’s distance from natural endowments and potentials have caused many problems. Human’s living spaces are less desirable for him, and have destroyed his comfort in many cases, as man-made things. In this regard, public open spaces in residential areas can be mentioned because they are usually considered among the most vulnerable s...

Phase-change materials (PCM) can be used to reduce thermal stress and improve thermal comfort for workers wearing protective clothing. The aim of this study was to investigate the effect of PCM in protective clothing used in simulated work situations. We hypothesized that it would be possible to optimize cooling performance with a design that focuses on careful positioning of PCM, minimizing to...

The origin and development of the adaptive approach to thermal comfort is explained. A number of the developments in the application of the theory are considered and the origin of the differences between adaptive thermal comfort and the ‘rational’ indices is explored. The application of the adaptive approach to thermal comfort standards is considered and recommendations made as to the best comf...
