Abstract

The paper presents a study of conditions for the diffusion of high performance windows, as an example of an energy efficient technology. High performance windows are loosely defined as windows promising significant energy efficiency improvements over conventional windows. Exact definitions vary from country to country, according to local conditions. Our study is based on Finnish and Swedish conditions.

We first build a framework drawing on theoretical and conceptual insights from literature on innovation diffusion and the dissemination of technologies. The empirical data comes from interviews with actors relevant in the context of window choice, both in renovation and new construction. We organise the empirical analysis in terms of stages of decisions and adoption, considering the actors involved in supply, demand and intermediate functions, and examining their interaction. We have also interviewed actors involved in cases where high performance windows were chosen.

The conclusions suggest ways in which to put the particular problems that could be solved by high performance windows on the agenda. Ways to improve the planning sequence of new construction and renovation are suggested, as are ways of giving high performance windows a fair chance in comparisons with conventional alternatives.
