Unraveling the adoption patterns of Energy Efficiency Measures in SMEs: A Mixed-Methods Analysis

This study investigates the adoption patterns of Energy Efficiency Measures (EEMs) in Small and Medium Enterprises (SMEs) in Switzerland, focusing on the influence of various factors such as EEM characteristics, company characteristics, and the role of energy auditors. A mixed-methods approach was employed, combining a logistic regression analysis of proposed and adopted EEMs’ data with the findings of a questionnaire answered by auditors active in the field. The logistic regression analysis revealed that investment cost remains a significant barrier to EEM adoption, particularly for medium consumers (MCs), and that other company-specific characteristics, such as the sector, can influence adoption patterns. These findings highlight critical factors for promoting EE in SMEs. The role of auditors is also discussed, with the suggestion that they might lack the training and the required soft skills to present EEMs as strategic investments and to influence SMEs’ decision-making.
