As technology has advanced so has the future role of living labs evolved. With the increased availability of wireless monitoring technologies including climate and activity sensors as well as self-reporting tools, the capability to convert virtually every house or building into a living lab has become a reality. ICT enables now the connectivity and merging of data sets across multiple living labs and monitored homes, providing a unique infrastructure for accelerating the adoption and marketing of innovations focused on sustainable living. The LivingLab approach is gaining more and more importance as a mechanism to study and shape sustainable behavior from the public and private perspective.@en

A key goal of LivingLabs is to provide industry, including large companies and SMEs, knowledge institutes and policymakers with a unique new infrastructure in testing and the co-development of sustainable products, services, legislation and combinations of these, takes place directly with users. The threeTier Model of living lab research which aims to connect industry, academic, and public stakeholders, while facilitating user-centred studies, is presented in this section consisting of: (a) insight research involving the study of current practices in existing homes, (b) studies in prototype houses equipped with innovative products and services focused on sustainable living, and (c) field testing, in which research prototypes are up-scaled such that existing homes can be equipped with innovative sustainable technologies.@en

There are an estimated 170 active living labs across the globe. All have common elements but not all of them contribute to the delivery of sustainable living. Here we consider the business models of sustainability in living labs (SusLabs). Specifically we review four active living laboratories that are part of the SusLab North West Europe network. We show that the business cases are different for at least two reasons. One is that each SusLab project has a specific focus even though all are seeking to develop energy efficient innovative products, services or systems. Examples of focus include demonstration projects, knowledge generation through research and business to business development. The other is that each came about for different reasons which might include significant public or private sponsorship, or through academia-business co-creation, and this too is reflected in the business case. We also show that the business cases are not static, but may evolve over time as opportunities are created and as partners develop a clearer understanding of the potential of each SusLab. We propose that, based on a common definition of a SusLab, theoretical considerations and societal needs, as well as insights from the cases, it should be possible to build a business case for a SusLab which draws on knowledge rather than learning-by-doing.
