Summary

The Austrian building sector accounts for 16 percent of national CO2 emissions. This makes it a key sector to decarbonize if long-term environmental targets are to be met. Relevant measures focus on the thermalrefurbishment of existing buildings and the phaseout of fossil-based technologies. The task specified by the Austrian government, involves replacing 600.000 oil heaters currently in use against renewable alternatives by 2035. This is the point of departure of this study. We investigate key barriers and solutions for the switch from fossil-based systems to comfort & climate boxes (CCBs) in the Austrian 1-2 family housing segment. CCBs are integrated systems encompassing a heat pump, storage and integrated control. The study applies a two-step approach: First, 11 problem-centered stakeholder interviews are conducted and evaluated using quantitative content analysis. Next, a stakeholder survey is conducted to assess the subjective relevance of barriers identified in the interviews. Results yield 45 barriers clustered into 6 categories. We identify discrepancies in the relevance-perceptions between stakeholder groups, especially between researchers and key market actors. We advise realigning research agendas along market actors’ perceptions, as these actors possess closeup insights about the market environment for CCBs.
