Comparison of FTX and FX systems from an energy efficiency and energy cost perspective in the country of Sweden : Comparison of two alternative renovation solutions for heat recovery in apartment buildings (Swedish)
Abstract [sv]

Denna rapport omfattar en energimässig och geografisk jämförelse mellan två alternativa renoveringslösningar för värmeåtervinning i flerbostadshus. Jämförelsen omfattar ett flerbostadstyphus som är representativt för miljonprogrammet, och genomfördes på grund av den debatt som pågår om vilket system som fungerar bäst vid renovering av flerbostadshus. Projektarbetet genomfördes med simuleringar i programmet TMF-Energi 2.2 framtaget av SP, Sveriges Tekniska Forskningsinstitut.

Rapportens syfte var att ta fram två geografiska representationer för Sverige som skulle visa var i landet två olika ventilations- och värmeåtervinningssystem fungerade mest primärenergi- samt energikostnadseffektivt.

Resultaten visade att det inte fanns någon gräns eller gråzon i landet, FTX-systemet var mer effektivt inom primärenergianvändning men inte lika energikostnadseffektivt, FX-systemet visade högre primärenergiförbrukning i hela landet men var mest energikostnadseffektivt.

Diskussionsdelen i rapporten innehåller diskussion över en rad olika ämnen t.ex. primärenergifaktorer, hur BBR kraven klaras, ”smutsig” el och hur en byggnads lufttäthet påverkar resultatet.

Slutsatserna för arbetet innefattar att FTX-systemet är mest primärenergieffektivt och FX-systemet mest energikostnadseffektivt. Det blev ingen gråzon eller gräns i landet för det valda testobjektet, och FTX-systemet påverkas mer av varierande lufttätheter än FX-systemet.

Abstract [en]

This report includes an energy- and geographical comparison between two alternative renovation solutions for heat recovery in apartment buildings. The survey includes a typical apartment building that is representative of the ‘Miljon Program’, and was carried out because of the ongoing debate about which system works best for the renovation of apartment buildings. The project work was carried out with simulations through an Excel-based program called TMF Energy 2.2 developed by SP, Sweden’s Technical Research Institute.

he purpose of this project was to develop two geographical representations of Sweden that would show where in the country the two different ventilation and heat recovery systems worked most efficiently regarding primary energy and energy costs for heating.

The results showed that there was no threshold, boundary of grey area in the country, one of the systems was more efficient in terms of primary energy use and the other system was more energy cost efficient.

The discussion section of this report includes a variety of topics such as primary energy factors, how to manage requirements, why airtightness affects the systems differently and energy costs for district heating.

The conclusions that were drawn from the results includes that the FTX-system is the most primary energy efficient and that the FX-system is the most energy cost efficient. There was no boundary or grey area in the country for the chosen building, and the FTX-system is affected more by varying airtightness than the FX-system.
