When new energy efficient products are struggling with their commercialisation and diffusion into widespread applications you would typically expect policy-makers and green lead-users to guide the way. This paper examines the case of the hot water circulator pump industry in Europe, where parts of the industry envisioned and worked for a voluntary energy label, bringing technological innovation, new business and energy savings of approx. 85% for each new circulator pump. The case study explores the complexities of innovation processes where technology, market, actors and policy co-evolve over time to transform an existing socio-technical regime. The paper highlights the importance of policies to reduce barriers towards innovation and energy efficiency and shows that it is not always policy-makers that establish the crucial policies that change the innovation dynamics for the benefit of the environment and the industry.

The European Energy Efficiency Directive requests the application of high quality and cost effective energy audits across Europe. The potential of up to 20% of energy savings shall be realized to follow the strategy of smart, sustainable, and inclusive growth. A number of barriers must be tackled to implement the Directive, especially among small and medium sized enterprises (SMEs). A large number of cost effective energy efficiency measures remains unimplemented because of financial reasons, a lack of information, and limited in-house skills. Information measures, audits, capacity buildings are suggested as potentially effective measures to support implementation of energy efficiency measures. Within the work described in this paper, an auditing approach was developed, focusing on modelling the energy consumption of an SME. The model of the energy consumption is built using simple MS Excel tools, dividing the process into unit operations and attributing annual consumption to these units, from measurements or by calculation. Consumption is linked to drivers of consumption and corresponding losses, thus developing an understanding of the origin of energy consumption, priorities, and the potential for reduction. The approach simultaneously addresses the needs for the identification of measures, capacity building, information and awareness raising. The auditing approach was tested with 280 companies in Austria, Bulgaria, Cyprus, Italy, Romania, Slovakia and Spain. A wide range of energy efficiency measures was identified and implemented, partly consisting of no-cost options, but partly also innovative technical solutions. Over EUR 10 million investments with a simple payback time of less than three years were triggered. 6500 toe per year of primary energy savings were realized, as well as greenhouse gas emission reductions of 13,500 tonnes per year.
