Among various types of ground heat exchangers (GHEXs), a coaxial-type GHEX exhibits outstanding thermal performance owing to the geometric characteristics of the concentric tube-in-tube configuration. In this study, a computational fluid dynamics (CFD) model was developed and verified using...

Behavioral approaches to reduce energy consumption in the built environment are becoming increasingly common. In particular, the application of individual feedback and the use of social norms have shown promise in the short term for improving occupant energy use behavior in the home. However,...
