Thorb’s mission is to maximize its residents’ home happiness. That’s why we’ve done extensive research into home happiness. This research has identified a total of nine happiness factors, and we have added one factor called ‘other’, which you can fill in yourself, so that we can learn from you as well. Using these happiness factors we formulated so-called Functional Requirements. If these requirements are fully met, home happiness will be as good as possible too. When you register as a participant you will immediately be able to view the nine happiness factors and the associated Functional Requirements. Not that we believe this is an exhaustive summary of determining factors and Functional Requirements. This is just the beginning. The home happiness model is dynamic and will develop further with the help of your concepts.
