Simulating co-diffusion of innovations: Feedback technology & behavioral change. Promotor: Prof.dr.ir. P.M. Herder (TBM).

This thesis explores how behavior-changing feedback devices can reduce energy demand of heating residential buildings. Greenhouse gas emissions of residential buildings need to be reduced as soon as possible, which can be achieved by changing heating behavior. Behavior-changing feedback devices are a useful approach to change energy-consumption behavior. They use the so-called 'nudge effect' to make consumers change their behavior – without forcing them to do so.

This thesis attempts to forecast the spreading of these devices among consumers - from their first adopters to a potential larger user base. In addition, the conservation behavior incentivized by feedback devices can also diffuse. The thesis captures both these 'diffusions of innovations' simulations. This shows the consequences of what happens if a feedback device will diffuse successfully.

Overall, results show that the impact of behavior-changing feedback devices can successfully be assessed by systematically simulating them. This relied on four pillars. First, technology assessment and simulations were closely linked to a novel framework of 'co-diffusion of technology and behavior'. This framework generalizes the understanding of the potential impact of feedback devices. Second, the simulation models were backed up by empirical data. Third, a thus empirical-based model then allowed to assess the potential for policies to influence the impact of feedback devices. Fourth, a method was developed to build simulation models from empirical data in an automated way. This new method can be expected to make similar assessments of technologies quicker and more accessible to non-programmers.
