“…In indoor environmental quality field studies dealing with thermal, acoustic, and illuminous conditions and indoor air quality at a same time, various types of scales have been used for subjective assessment. Interval scales of 4-7 points [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35] have been frequently used for combined environmental assessments. Dichotomous scales [21,22,[36][37][38], 11-point scales [39], 13-point scales [39], and VASs [20,36] were also used for indoor environmental assessments.…”

Response scales are widely used to assess the personal experience of sensation and perception in built environments, and have a great impact on the quality of the responses. The purpose of this study was to investigate the effects of response scales on human sensation and perception in moderate indoor environments. Four different response scales were compared under three room temperatures (19.0 °C, 24.5 °C, and 30.0 °C) and five acoustic stimuli (ambient noise, 42 and 61 dBA × water sounds and traffic noise): a bipolar seven-point scale according to ISO 10551:1995, a unipolar 11-point scale according to ISO/TS 15666:2003, these two scales combined for each sensory comfort assessment, and a bipolar visual analogue scale. The degree of relative differentiation based on indoor physical factors made no significant difference across the four response scales. Therefore, the effects of physical factors on human response could be assessed by using any of the four scales tested in this study, with a statistical significance at P < 0.05 in moderate environments. The choice of response scale would depend not only on the type of physical stimulus but also on the question of sensation or perception. The reliability of each response scale was different according to the subjective attributes. The bipolar visual analogue scale was subjectively preferred by the respondents.

“…In today's buildings, the importance of indoor environmental quality (IEQ) has been increasing, especially the factors of thermal and visual quality, due to its significant impacts on occupants' productivity, health, and quality of life [1][2][3][4][5][6][7][8][9][10]. This indoor environmental significance has motivated numerous design and technology advancements, especially as applied to modern building environmental controls.…”

The quality and controllability of the building façade can significantly contribute to building indoor environmental quality (IEQ) as well as the building's energy efficiency. Advanced technologies that support a façade's dynamic response to climatic changes, such as electrochromic (dynamic) glazing, have emerged as smart systems for IEQ and environmental sustainability. This research summarizes a four-season study of office workers moving from a floor with conventional blinds to work environments equipped with smart dynamic glazing which changes tint in response to weather condition to control daylighting levels. Multiple occupant environmental satisfaction surveys were conducted over one year to investigate differences in environmental and psychological responses to office settings with manual, and often static, facades as compared to offices with dynamic glazing. This research confirms that dynamic glazing significantly affected occupants' environmental satisfaction-enhancing individuals' environmental perceptions and psychological health-as compared to manual blinds. It reveals that the occupants in work environments with dynamic glazing reported 21.7% higher productivity gains, 24.8% increased ability to relax, 12.7% improved concentration, 25.3% better moods and 29.4% greater alertness than when they were in offices in the same building with manual shading devices. Also, the dynamic feature of the smart glazing showed a significant contribution to perceived work productivity while enhancing positive emotional responses by an average of 26%.Energies 2020, 13, 60 2 of 20 sustainability. Most significantly, dynamic glazing is known to contribute to reduced glare, thermal discomfort and reduced cooling loads. The visual transmittance of dynamic glazing can be increased or decreased based on pre-defined control algorithms, and it can control the illuminance of natural light admitted through glazing in an optimal way to enhance the visual quality and allow for continuous window views without compromising the thermal-quality condition. These technical merits have been especially important for office and healthcare facilities where the occupants' environmental health and work productivity are important.Recent research has investigated the efficacy of dynamic glass, focusing predominantly on energy performance. Tavares et al. investigated the energy conservation potential of adopting electrochromic windows in a Mediterranean climate [15]. The research confirmed that electrochromic glazing saved 15-20% energy in a cooling dominant climate depending on orientation, and the impact was most significant for the west façade. DeForest et al. simulated energy consumption of three building types in 16 U.S. climate zones, identifying that electrochromic windows outperformed other glazing choices in x of the 48 set of locations and building types [16]. Picco et al. used both experimental tests and computation simulations to evaluate the impact of electrochromic glazing on energy efficiency [17].This study tested four different...

“…In the office, there is no significant difference amongst age groups regarding visual satisfaction [10]; The satisfaction with lighting of those workers occupying stations closer to the windows was significantly higher than those located in the core areas; However, gender elicited a difference in the evaluation of satisfaction with lighting only in the core areas and men's ratings were higher than the women's [11]; Significant gender differences were observed for mean satisfaction level with each indoor environmental quality factor based on data from office buildings [12]; User satisfaction revealed significant differences in illuminance level in different workstation locations in modern offices located in Southern California [13]. In Hong Kong housing units, no significant difference was found between males and females, however, distinct differences were found amongst age groups in satisfaction evaluation, and the elders' ratings were the highest [14].…”
