Two eight-story wood-framed residential buildings with the Swedish 2012passive house standard were built in 2009 in the Portvakten Söder quarter in the city of Växjöin Sweden. In this paper, we present the monitored specific energy use of the buildings andcompare to the requirements of the Swedish building code and recommendation for passivehouses. We also estimated the primary energy use and CO2 emissions and investigated thetenants’ views and experiences of the two buildings. Results show that the actual specificenergy use of 40.2 kWh/m2Atemp/year in the Portvakten Söder building fulfills, by a goodmargin, the requirements of the Swedish building code and the recommended passive housestandard, but is higher than projected. Applying a marginal perspective, the calculatedprimary energy use and carbon dioxide emission from operating the buildings (excludinghousehold electricity) was 40 kWh/m2Atemp/year and zero, respectively. Responses of 20 tenantsto a mail-in questionnaire survey showed that over 90% were satisfied with their apartments.
