We relate our previous as well as ongoing research in the domain of smart homes to the concept of HabiTech. HabiTech can benefit from existing approaches and findings in a broader context of whole buildings or communities within. Along with data comes context of data capture and data interpretation in different dimensions (spatial, temporal, social). For defining what is 'community' proximity plays a crucial role in context, both spatially as well as socially. A participatory approach for research in living in sensing environments is promising to address complexity as well as interests of different stakeholders. Often it is the complex context that makes even simple sensor data sensitive, i.e. in terms of privacy. When it comes to handle shared data then concepts from the physical world for shared spaces might be related back to the data domain.
