Abstract

Purpose

The inherent characteristics of professional services (i.e. high in credence properties, customized and featuring information asymmetry) often cause difficulties for clients to confidently evaluate technical outcomes before, during or even after service delivery. This results in considerable client psychological discomfort. This study aims to blend a revised social interaction model and uncertainty reduction theory to investigate the role that service provider’s interpersonal communication style plays in establishing client psychological comfort and satisfaction in a health-care context.

Design/methodology/approach

The study draws on cross-sectional data collected from 355 hospital patients following visiting a physician plus an experimental design in an Eastern culture (Thailand).

Findings

The study reveals three key findings. First, an affiliative communication style is positively associated with psychological comfort, but not so a dominant communications style. When both styles are presented, the high-affiliative style overshadows the low-dominant style and creates the highest psychological comfort. Second, clients’ perceptions of professional’s affiliative and dominant styles influence psychological comfort differentially under varying conditions of clients’ cognitive social capital, collectivist value-orientation but not service criticality. Third, a competing model suggests psychological comfort acts as a partial mediator between affiliative communication style and satisfaction.

Research limitations/implications

To generalize the findings, further studies might be conducted in other professional services and in individualist Western cultures.

Practical implications

The findings have important managerial implications for the appropriate use of communication style to build psychological comfort and engage clients of professional services firms.

Social implications

The findings shed light on the important role of an everyday social function – interpersonal communications and how this impacts client psychological comfort and satisfaction.

Originality/value

This is one of the few studies in a services context that examines the impact of professionals’ communications style. Moreover, it examines the impact of cultural value-orientation, cognitive social capital, service criticality in moderating the communications style – client psychological comfort relationship.

Abstract

Purpose

Sports garments play an important role in the well-being of an athlete by protecting the wearer from changing environmental conditions and providing a comfortable feel. Clothing requirements have changed in recent years and demand for apparel with a higher comfort performance has been rising. Hence, the purpose of this study is to explore consumers’ expectations and perception of comfort and to examine how different textiles are perceived by consumers to provide useful knowledge that allows to engineer comfort into fabrics and sports garments.

Design/methodology/approach

This online survey comprised 292 respondents, classified by sex, age, nationality and physical activity. The respondents were asked a total of 18 questions through the Bristol Online Survey tool to explore expectation, perception and preference of clothing comfort, specifically of sportswear.

Findings

Fit and comfort are closely linked together, both forming part of the clothing comfort concept. When purchasing garments online, the haptics of fabrics were identified as a crucial missing parameter. However, priorities of attributes within the concept varied according to the person’s sex and nationality. Women put more emphasis on garment fit and showed a higher need for tactile input, whereas men prioritised physiological comfort descriptors, i.e. properties which facilitate thermoregulation. Furthermore, there is an increased importance of physiological comfort parameters for people exercising for 10 or more hours per week. Finally, it was possible to identify common associations and preferences for textile materials (cotton, polyester, cotton/polyester blend and wool). However, consideration should be taken concerning sex and nationality.

Originality/value

Sex and nationality are parameters modulating the clothing comfort concept and the conceptualised feel of materials. Therefore, the sex and nationality of the end-consumer should be considered during the development phase of sports garments and particular attention should be given to the targeted market in which these will be sold.

Abstract

Purpose

As suggested in many previous studies, good thermal comfort and indoor air quality (IAQ) played a significant role in ensuring human comfort, health and productivity in buildings. Hence, this study aims to evaluate the thermal comfort and IAQ conditions of open-plan office areas within a green-certified campus building through a post occupancy evaluation.

Design/methodology/approach

Using the field measurement method, environmental dataloggers were positioned at three office areas during office hours to measure the levels of thermal comfort parameters, CO2 concentrations and the supply air rates. At the same time, questionnaires were distributed to the available office staff to obtain their perception of the indoor environment. The findings were then compared with the recommended environmental comfort ranges and used to calculate the thermal comfort indices.

Findings

Results show that the physical parameters were generally within acceptable ranges of a local guideline. The neutral temperature based on the actual mean vote at these areas was 23.9°C, which is slightly lower than the predicted thermal neutrality of 25.2°C. From the surveyed findings, about 81% of the occupants found their thermal environment comfortable with high adaptation rates. A preference for cooler environments was found among the workers. Meanwhile, the air quality was perceived to be clean by a majority of the respondents, and the mean ventilation rate per person was identified to be sufficient.

Research limitations/implications

This study focussed on the thermal environment and air quality at selected office spaces only. More work should be carried out in other regularly occupied workplaces and study areas of the green educational building to allow a more thorough analysis of the indoor air conditions.

Practical implications

This paper highlights on the thermal comfort and air quality conditions of the air-conditioned office spaces in a green-certified campus building and is intended to assist the building services engineers in effective air conditioning control. The findings reported are useful for thermal comfort, IAQ and subsequently energy efficiency improvements in such building type where adjustments on the air temperature set-point can be considered according to the actual requirements. This study will be extended to other green campus spaces for a more exhaustive analysis of the indoor environment.

Originality/value

There is limited information pertaining to the environmental comfort levels in offices of green campus in the tropics. This study is, therefore, one of the earliest attempts to directly explore the thermal comfort and IAQ conditions in such workplace using both on-site physical measurement and questionnaire survey.

Abstract

Purpose

In vernacular buildings, many climatic and passive solutions have been used to create indoor thermal comfort. Seasonal occupant movement is an example of a traditional response to increasing thermal comfort. This article investigates the influence of these user behaviours on thermal comfort in courtyard houses.

Design/methodology/approach

Parametric models of three different scenarios of courtyard houses are simulated. The courtyard houses are located in Shiraz, Iran, and share the same orientation and construction materials. To enhance the accuracy of the study, the indoor adaptive thermal comfort (ATC) analysis is performed with three different window-to-wall ratios (WWR) of 25, 50 and 75%. The ACT analysis is performed on an hourly basis for summer and winter scenarios.

Findings

The results demonstrate that the indoor ATC is 8.3% higher in winter than in the summer in the seasonal zones. During the summer, the amount of ATC is relatively sustained in all zones. Unlike common beliefs, seasonal movement can enhance the ATC, especially during winter, specifically in the northern part of the courtyard. In northern zones, the seasonal movement of occupants improves the indoor ATC from 10.1 to 23.7%, and in southern zones, the improvement is from 2.2 to 4.8%.

Originality/value

This research presents a new numerical investigation into occupants' seasonal movements in courtyard houses during summer and winter. It provides a precise pattern to show how much this seasonal movement can affect the habitant's ATC.

Abstract

Purpose

This study aims to analyze the technical, environmental, economic and thermal comfort impacts of implementing passive measures and heating systems in Ciudad Verde, a large-scale social housing project located at the periphery of Bogota, Colombia.

Design/methodology/approach

A system dynamics (SD) model is proposed to evaluate scenarios through counterfactual experiments, including technical, environmental and economic components. Model inputs are obtained from building energy simulation models and data collected from official reports, public policy documents and construction records.

Findings

Results suggest that the use of heating systems is the best choice to achieve thermal comfort conditions throughout the day. However, both the capital expenditures and CO2 emissions associated with such system make their adoption very difficult. In line with that, the use of heating systems in combination with passive measures stands out as a viable solution since their costs are affordable and their use contributes to reducing CO2 emissions.

Originality/value

The proposed model recreates the dynamics underlying social housing construction processes, the adoption of heating systems and passive measures in low-income dwellings and their corresponding impact on CO2 emissions and indoor thermal comfort conditions. The model can be employed as a support tool in the formulation of social housing policies associated with thermal comfort specifications. In this way, the model represents a first step toward incorporating thermal-related variables into the decision-making processes related to social housing planning and development.

Abstract

Purpose

Improper evaluation and information mismanagement concerning thermal comfort appears to negatively affect occupants' satisfaction and building energy consumption in precast concrete (PC) building contexts. Predictive models are particularly problematic in PC building construction projects where natural ventilation levels do not coincide with occupants' thermal comfort and thermal sensation specifications.

Design/methodology/approach

A systematic literature review is undertaken to explore the viability and benefits of a new ICT-based approach for meeting social and environmental objectives.

Findings

Sophisticated thermal comfort system solutions are essential for optimising thermal comfort and saving energy in PC building construction projects.

Originality/value

It is imperative that designers and manufacturers are kept up-to-date with the possibilities and potentials associated with new and nascent technologies so that building projects can meet key sustainability criteria.

Abstract

Purpose

A major challenge faced by West Africa is to find comfortable housing as a result of climate change and population growth. The climatic adaptation of buildings and their indoor environment become an essential condition for maintaining the health and productivity of the occupants. This paper proposes a model to assess the thermal comfort of naturally ventilated buildings in hot and dry climates in Burkina Faso.

Design/methodology/approach

The proposed method is an adaptive model which relies on a combination of parameters such as the operative temperature, the new effective temperature and the basic parameters of thermal comfort. It consists in proposing the zones of thermal comfort on the diagram of the humid air for each climatic region.

Findings

A decision-making tool is set up for evaluating the comfort of buildings to better consider the bio-climatic concept through a long-term comfort index. This comfort index is defined and is used to assess the degree of thermal discomfort for various types of housing. Two natural ventilation pilot buildings located in Ouagadougou were considered. The results show that the pilot building whose wall are is made of Earth blocks achieves 26.4% of thermal comfort while the building made of hollow cement block achieves 25.8% of thermal comfort.

Originality/value

The decision-making tool proposed in the present study allow building stakeholders to better and easily design, assess and improve the thermal environment of buildings.

Abstract

Purpose

In cities with high density, heat is often trapped between buildings which increases the frequency and intensity of heat events. Researchers have focused on developing strategies to mitigate the negative impacts of heat in cities. Adopting green infrastructure and cooling pavements are some of the many ways to promote thermal comfort against heat. The purpose of this study is to improve microclimate conditions and thermal comfort levels in high-density living conditions in Seoul, South Korea.

Design/methodology/approach

This study compares six design alternatives of an apartment complex with different paving and planting systems. It also examines the thermal outcome of the alternatives under normal and extreme heat conditions to suggest strategies to secure acceptable thermal comfort levels for the inhabitants. Each alternative is analyzed using ENVI-met, a software program that simulates microclimate conditions and thermal comfort features based on relationships among buildings, vegetation and pavements.

Findings

The results indicate that grass paving was more effective than stone paving in lowering air temperature and improving thermal comfort at the near-surface level. Coniferous trees were found to be more effective than broadleaf trees in reducing temperature. Thermal comfort levels were most improved when coniferous trees were planted in paired settings.

Practical implications

Landscape elements show promise for the improvement of thermal conditions because it is much easier to redesign landscape elements, such as paving or planting, than to change fixed urban elements like buildings and roads. The results identified the potential of landscape design for improving microclimate and thermal comfort in urban residential complexes.

Originality/value

The results contribute to the literature by examining the effect of tree species and layout on thermal comfort levels, which has been rarely investigated in previous studies.

Abstract

Purpose

The purpose of this paper is to investigate the perceived thermal comfort experienced by active Muslim women (AMW) wearing hijabs determined by their experience of comfort sensation while doing sports activities or regular exercises. This study also examines whether the casual hijabs which are widely used among AMW are able to supply the appropriate comfort for active purposes.

Design/methodology/approach

This study used the quantitative method using survey questionnaires to collect 100 primary data obtained from AMW respondents who are university students located around the Klang Valley region in Malaysia.

Findings

Based on the overall results, this study suggests that the common hijabs that are used for casual applications do not offer sufficient comfort to Muslim women while performing sports activities or regular exercises.

Research limitations/implications

The outcome of this study will help to gain a better understanding on hijab preferences and comfort experienced from the viewpoint of regular hijab users. The information will assist industries to consider the selection of the right materials when developing sportswear hijabs to provide better comfort for more AMW in the near future. The method used in this study is useful to gain information on consumer’s profile and value-added details about the discomfort aspects of hijab which are scarce in the existing literature on thermal comfort.

Originality/value

This study was conducted to explore the type of hijabs commonly worn by AMW while performing sports activities and to obtain their views on the perceived thermal comfort.

Abstract

Purpose

This paper aims to measure the thermal comfort conditions and indoor air quality parameters, through on-site measurements taken in the areas mostly occupied by the passengers and airport staff. Terminal buildings consist of areas with various functions. Heating, ventilation and air conditioning requirements vary from area to area, thus leading to challenges in the management of indoor environment quality. Therefore, the study focuses on investigating the indoor environment conditions in various areas of the terminal buildings.

Design/methodology/approach

In this study, the thermal comfort and indoor air quality were evaluated based on the parameters [CO2 concentration, relative humidity, temperature, predicted mean vote (PMV) and predicted percentage of dissatisfied (PPD)] collected for summer 2019 from different zones inside the International Dalaman Airport terminal building located in the southwest of Turkey. The measurements were performed in the areas mostly occupied by the airport staff and passengers (check-in area, security control areas, international departure lounge, domestic departure lounge and baggage claim hall).

Findings

As a result of the study, it was observed that the CO2 concentration was 480–965 ppm, the relative humidity was 51.9–75.8% and the temperature was in the range of 23.9°C–28.3°C inside the airport terminal. The PMV values were determined to be in the range of −0.23 to 0.67, and the PPD values 5–15%, which are used to measure the thermal comfort conditions.

Originality/value

There has been limited study on the determination of the indoor air quality in airport terminals and the investigation of the thermal comfort conditions. However, in this study, indoor air quality and thermal comfort conditions were determined by on-site measurements in the five mostly occupied areas by passengers and employees in the terminal building.
