This article focuses on how Sweden’s largest tenant–owners’ organization, HSB, dealswith energy efficiency. The aim is to examine HSB’s energy goals, how they are determined and howthey should be implemented at four levels: the national association, the regional office, the localhousing co-operatives and the tenant–owners. Representatives of all four levels were interviewed.Achieving energy goals calls for common strategies involving all levels of HSB. The analysisindicates that ambitious energy goals have not been followed up with similarly ambitiousimplementation plans by the organization. Champions in HSB mobilize support for energy efficiencyat the regional and co-operative levels, but have no effect on household engagement. The lack ofinterest in energy efficiency on the part of households was not only due to the collective metering ofenergy, but also because energy constitutes only a small part of household life.
