The belief that the environment shapes human emotions followed by behaviour is not new, as acknowledged by many researchers. Recent studies show that the most significant illness by 2030 is depression, as most of our time spent inside the buildings. Hence, the importance of "re-connecting architecture with emotions" is an essential solution to improve the quality of life. A single-case experimental design (SCED) aimed to investigate the relationship between neural underpinnings of the brain, for a single participant and various environments. Data collected was based on the Electroencephalography tests. Findings showed a significant contrast between different water elements and environmental settings, each with its unique effect on participant emotions as well as the electrical activity of the brain.
