The psychological drivers of design that evoke emotion and behavior will be presented. What shapes and colours are most pleasing, the emotions they evoke, and how aesthetics impact the psychological state of occupants will be investigated. Other discussion points include: • How to attract tenants and retain employees by activating common spaces to enliven buildings by offering more amenities and adding vibrancy. • Biophilic designs and how they help to connect humans to natural environments in order to strengthen and support psychological and sociological needs resulting in relaxed absorption, effective and efficient cognition, and strengthened health responses contributing to well-being. • Situational constructs that trump disposition and can be used to induce favored behavior despite innate personality traits and tendencies. • Feature frequency and how position, perspective, and design can impact traffic flow. • How variables such as lighting and views, sound control and space, and ventilation and aesthetics play a role in productivity and performance. • Desired emotion and occupant behavior can be supported by creating congruent situational attributes. • Design principles such as the Cathedral Effect, Hick’s Law, Highlighting, Modularity, Nudge, Operant Conditioning, and Attractiveness Bias can impact occupant behavior.
