  Living labs have been established across different countries to evaluate how
the interaction between humans and buildings can be optimized to improve
comfort, health, and energy savings. However, existing living labs can be too
project-specific, not scalable, and inflexible for comparison against other
labs. Furthermore, the lack of transparency in its software infrastructure
inhibits opportunities for critique and reuse, reducing the platform's overall
potential. In the face of climate change and global energy shortage, we
envision the future of living labs to be open source and scalable to support
the integration of different IoTs, subjective measures, human-building
interactions, security, and privacy contexts. In this work, we share our living
lab software stack and present our experience developing a platform that
supports qualitative and quantitative experiments from the ground up. We
propose the first open-source interoperable living lab platform for
multidisciplinary smart environment research.
