Innovation Diffusion and Substitution in Fragmented, Inert Systems

abstract Mitigating climate change is one of the most significant challenges facing humankind. The building sector of a developing country requires about one fourth of that country’s energy demand. Reducing this demand, and thus abating greenhouse gas (GHG) emissions, is often imperative, but also problematic since the level of energy efficiency in the building stock is considerably low. Policy makers therefore ask themselves how improvements in energy efficiency can be achieved. One part of the answer is the availability of energy-efficient building codes, which require improved energy-efficient technologies. This thesis develops a model about how the energy efficiency required by building codes evolves. It shows that the evolution of energy efficiency results from complex interactions among agents in the residential building sector. How can policy makers influence this system to enhance energy efficiency? What reductions of GHG emissions can be achieved? Using a case study design, the thesis elaborates a dynamic model of the Swiss residential built environment that explains the evolution of energy efficiency in the Swiss building stock over four decades. This model then enables one to estimate possible reductions of GHG emissions in the future.
