“…The window opening behavior was also found effective in temperate climates such as Denmark where residents opened windows according to outdoor climates [28]. Research in other climates showed that these adaptive behaviors in naturally ventilated or mixed-mode conditions were closely linked to and can be predicted by outdoor temperature [29,36]. These precedent studies support the present study that adaptive behaviors can help occupants in naturally ventilated buildings in tropical climates adapt to thermal environments beyond the comfort zone.…”

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.

“…These variations are partly attributed to differences in occupancy patterns (Branco et al 2004;Haas et al 1998;Leth-Petersen and Togeby 2001;Jeeninga et al 2001;Andersen et al 2009;Groot et al 2008;Linden et al 2006;Papakostas and Satiropoulos 2007), which are determined by household characteristics, lifestyle, cognitive variables and perception of comfort (Andersen et al 2009;Poortinga et al 2005;Vringer and Blok 2007;Schweiker and Shukuya 2009). The relationship between the amount of energy used for heating and household characteristics such as age, composition and size has been extensively studied internationally (Leth-Petersen and Togeby 2001;Sardianou 2008;Andersen et al 2009;Groot et al 2008;Linden et al 2006;Schweiker and Shukuya 2009;Lenzen et al 2006;Liao and Chang 2002;Biesiot and Noorman 1999;Vringer 2005). Other studies have looked at the effect of household motivation, attitudes and values (Linden et al 2006;Poortinga et al 2005;Vringer and Blok 2007;Schweiker and Shukuya 2009;Raaij and Verhallen 1983), although these have been more difficult to relate to energy use.…”

In addition, authors agree that the way in which the occupant controls the heating and ventilation systems is an important factor.…”

Occupant behaviour in energy efficient dwellings: evidence of a rebound effect

The energy required for space heating has been significantly reduced in recent decades by making use of insulation and more efficient heating and ventilation systems. Even so, wide variations in energy consumption are still observed between similar dwellings and between actual and predicted levels. It is thought that these variations stem from differences in occupant behaviour, the structural quality of the building, and a rebound effect. This paper statistically examines differences in occupant behaviour in relation to the building characteristics of the housing stock in the Netherlands and explores the possible existence of a rebound effect on the consumption of energy for space heating. Rebound effect can be defined as the increase on energy consumption in services for which improvements in energy efficiency reduce the costs. We found that although energy consumption is lower in energy efficient dwellings, analysis of the behaviour variables indicates their occupants tend to prefer higher indoor temperatures and to ventilate less. This finding might be related to a rebound effect on occupant behaviour. However, the improvement of thermal properties and systems efficiency still lead to a reduction on energy consumption for heating.

“…For example, the use of windows by building occupants has been shown to be closely related to prevailing indoor and outdoor conditions [16,17]. Field studies on the use of air-conditioning systems by building occupants are relatively rare, but the existing research reveals that occupant control of air-conditioning systems is a key determinant in changes in building energy consumption [18,19]. Thus, it is evident that occupant behavior should be considered in any analysis of the effects of climate change on energy use in buildings.…”

Occupant factor is a critical element in the overall energy consumption of buildings. This study aims to reveal how occupant factors influence the energy consumption of example buildings in Seoul, Tokyo, and Hong Kong under climate change projections, and to prioritize factors with energy saving potential for buildings in consideration of future climate change. The study finds that the cooling degree-hours base of 23.3 • C in the three cities sharply increases with future climate change by analyzing future hourly weather data produced herein. Simulations are made with EnergyPlus Runtime Language (Erl) for modeling occupant behavior. The simulation results reveal that a dynamic thermostat control based on an adaptive comfort model is an effective method to reduce cooling energy consumption under future climate change, reducing cooling energy consumption by up to 18% in some instances. In particular, we reveal that a combined application of the adaptive comfort control, nighttime ventilation, and the use of occupancy-based lighting and equipment result in reducing cooling energy consumption by 28%. The outcomes of this study are potentially useful in providing cost-effective solutions to adapt buildings for future climate change with simple modifications to occupant behavior. Also, the roles of renewable energy are briefly discussed.
