Energieffektivisering av äldre småhus avseende tekniska åtgärder och brukarbeteende

- Abstract (Swedish)
- Syftet med denna studie är att undersöka hur olika energieffektiva renoveringsåtgärder kan påverka energiprestandan i äldre småhus. Studien omfattar en genomgång av tidigare forskning och en fallstudie av ett småhus byggt 1919, och undersöker effekten av tekniska åtgärder och olika användarbeteenden på energiprestanda. Fallstudien genomfördes med hjälp av simuleringsprogrammet IDA ICE. Det innebar också en ekonomisk lönsamhetsbedömning av de olika renoveringsåtgärderna. Resultatet av studien visar att samtliga sju undersökta renoveringsåtgärder minskade värmebehovet för fallstudiehuset. Installation av två värmepumpar i kombination med en extra isolerad fasad visade sig minska värmebehovet mest. Resultatet av den ekonomiska... (More)

Installation av två värmepumpar i kombination med en extra isolerad fasad visade sig minska värmebehovet mest. Resultatet av den ekonomiska bärkraftsbedömningen visade att majoriteten av renoveringsåtgärderna kan anses lönsamma över tid, även om lönsamheten i hög grad är beroende av framtida energipriser. Studien visar också att olika användarbeteenden både kan öka och minska behovet av uppvärmning. (Less)
- Abstract
- The purpose of this study is to investigate how different energy-efficient renovation measures may affect the energy performance of older detached houses. The study involves a review of previous research and a case study of one detached house built in 1919, and investigates the impact of technical measures and different user behaviors on energy performance. The case study was conducted by using the simulation program IDA ICE. It also involved a financial profitability assessment of the various renovation measures. The results of the study show that all seven investigated renovation measures reduced the heating requirement for the case study house.

The results of the study show that all seven investigated renovation measures reduced the heating requirement for the case study house. Installation of two heat pumps in combination with an additional insulated facade proved to reduce the heating requirement the most. The result of the financial viability assessment showed that the majority of the renovation measures can be considered profitable over time, although profitability is highly dependent on future energy prices. The study also reveals that different user behaviors can both increase and reduce the need for heating. (Less)
