Summary of literature review related to personal control.
| Authors | Control manipulation | Setting | Participants | Outcomes |
|---|---|---|---|---|
| Boerstra et al. 2015 [162] | Personal fan vs. recreation of fan usage through experimenter | Lab (office mock-up) | N = 23 | No effect on thermal sensation, preference, preference, and acceptance |
| Brager, Paliaga, & de Dear 2004 [163] | High vs low degrees of control over windows | Field (office) | N = 38 |
Significant effect on neutral temperature in warm season (High control: 23 °C, low control: 21.5 °C) Effect not calculable for cool season |
| Cao et al. 2014 [164] | Individual heating vs. district heating without control | Field (residential) | N = 24 (in ten apartments) | Significant effect on neutral temperature in winter (high control 18.6 °C; no control: 22 °C) |
| Luo et al. 2016 [165] | No control vs. placebo control | Lab | N = 22 | Significant effect on TSV and TCV in 4 out of 5 temperatures (more neutral TSV and greater comfort with control)5 |
| Luo et al. 2014 [166] | Individual heating vs. district heating without control | Field (residential) | N = 139 households (but in 3 groups, only 2 considered here) | Effect on neutral temperature (control: 20.7 °C, no control 18.1 °C) |
| Schweiker &Wagner 2016 [48] | Individual vs. multi-person set-up | Lab (office mock-up) | N = 36 | Significant effect on neutral temperature (2 °C difference between highest and lowest PC) |
| Schweiker et al. 2012 [167] | Control over clothes, windows, shading, fans vs. only clothing | Lab (office mock-up) | N = 21 | Significant effect on neutral temperature and comfort range (Tn more than 3K lower for no control and comfort range being 6K narrower) |
| Zhai et al. 2017 [168] | Personally controlled fans vs, experimenter set fans6 | Lab (office mock-up) | N = 23 |
No effect on thermal sensation votes as a function of effective temperature No effect of control at 24 and 26 °C on thermal comfort and preference |
| Zhou et al. 2014 [101] | No control (but signaling of discomfort) vs. control (activated through same signal)7 | Lab | N = 15 | Significant effect on TSV (control vs. none: decrease by 0.4–0.5) and on TCV (control vs. none: increase by 0.3–0.4) |
