“…Currently, a number of methods are available to help monitor principle occupant behaviour, e.g. window behaviour and heating behaviour, in buildings, for example, self-recording by the building occupants (Haldi and Robinson, 2008;Raja et al), electronic measurement devices (Spataru andGillott 2011, Yun andSteemers, 2010), surveyor observation (Wei et al 2013;Zhang and Barrett, 2012) and self-estimation by the building occupants (Guerra Santin, 2013;Huang et al 2014). A deep understanding of the advantages and disadvantages of each method is still highly needed so the most suitable method for refurbishment applications can be identified.…”

In building refurbishment projects, dynamic building simulation is popularly used to predict the energy saving potential of various refurbishment scenarios.However, in this process, it is not clear whether occupant behaviour should be carefully modelled due to the lack of evidence about its impact on the prediction results. To answer this question, this study selected an UK public building and used dynamic building simulation to predict the energy saving potential of common refurbishment measures, under various occupant behavioural conditions. The results revealed that for the case study building occupants' heating behaviour has a significant impact on the predicted energy saving potential of all evaluated refurbishment measures: when changing from passive heating users to active heating users, the energy saving potential was nearly doubled. Although occupants' window opening behaviour was not shown to be as important as heating behaviour for the refurbishment of the case study building, it has a specific influence on the refurbishment measure of increasing window layers: when windows are opened longer, the effectiveness of increasing window layers on promoting the building energy efficiency is decreased. According to the findings from this study, occupant behaviour should be considered as an important aspect in building refurbishment projects.

“…A future study will use sophisticated statistical methods to estimate the probability of a certain adaptive behavior happening as a function of temperature variations. The common statistical method used in similar studies is multiple logistic regression technique [30][31][32]36]. Usually, the adaptive behaviors should be analyzed separately: using each behavior as the dependent variable and the outdoor air temperature as the dependent variable [28].…”

“…They derived statistical models to predict the percentage of adaptive behaviors such as operation of air-conditioners, heaters, fans and windows, as a function of outdoor temperature. The adaptive behaviors and related thermal environments can also be found in office buildings with different climates [30][31][32].…”

Abstract:This article presents a pilot study of thermal comfort and adaptive behaviors of occupants who live in naturally ventilated dormitories at the campus of the National University of Singapore. A longitudinal survey and field measurement were conducted to measure thermal comfort, adaptive behaviors and indoor environment qualities. This study revealed that occupants living in naturally ventilated buildings in tropics were exposed to higher operative temperatures than what American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) comfort standards recommend for naturally conditioned spaces. However, they still felt that such conditions were acceptable. Two behavioral adjustments were found to have profound impacts on occupants' acceptance of the imposed heat stresses: (1) increasing the indoor air velocity by turning on mechanical fans and opening the door/windows for cross ventilation, and (2) reducing clothing insulation by changing clothes and dressing in fewer clothes. Higher indoor air velocities were also associated with greater satisfaction with indoor air quality. The future study should develop a statistical model to correlate adaptive behaviors with temperature variations for tropical climates.

“…Unfortunately, manually controlled internal solar shades are widely used in office buildings in China [13]. Moreover, occupants' shade control is not as efficient as motorized systems since occupants' behavior is stochastic [13][14][15][16]. Therefore, the rigorous evaluation of the impact of manual solar shades on indoor visual comfort should account for the stochastic characteristic of occupants' behavior.…”

Daylight plays a significant role in sustainable building design. The purpose of this paper was to investigate the impact of manual solar shades on indoor visual comfort. A developed stochastic model for manual solar shades was modeled in Building Controls Virtual Test Bed, which was coupled with EnergyPlus for co-simulation. Movable solar shades were compared with two unshaded windows. Results show that movable solar shades have more than half of the working hours with a comfortable illuminance level, which is about twice higher than low-e windows, with a less significant daylight illuminance fluctuation. For glare protection, movable solar shades increase comfortable visual conditions by about 20% compared to low-e windows. Moreover, the intolerable glare perception could be reduced by more than 20% for movable solar shades.
