Abstract
Dette speciale sammenligner klimaaftrykket fra tre typer ventilationskanaler i danske erhvervsbygninger: skræddersyet tekstil, glasuld og galvaniseret stål. To konkrete bygninger—Sofiendalskolen og City Campus Aalborg—blev brugt som cases. Ventilationssystemerne blev først dimensioneret og derefter vurderet med værktøjet LCAbyg. Der blev lavet en livscyklusvurdering (LCA) fra vugge til grav, som omfattede produktion, udskiftninger, energiforbrug i drift og behandling ved endt levetid. Resultaterne viser, at materialevalget har stor betydning. Tekstilkanaler giver lavere CO2-udledning og et mindre samlet miljøaftryk end kanaler af galvaniseret stål. Omvendt medfører kanaler af glasuld højere CO2-udledning, fordi de oftere skal skiftes. Indsigterne kan støtte mere bæredygtige materialevalg til ventilation i erhvervsbyggeri.
This thesis compares the climate impact of three types of ventilation ductwork in Danish commercial buildings: tailor-made fabric, glass wool, and galvanized steel. Two real buildings—Sofiendalskolen and City Campus Aalborg—serve as case studies. The ventilation systems were first designed and then evaluated using the LCAbyg tool. A life cycle assessment (LCA) from cradle to grave covered production, replacements, energy use during operation, and end-of-life treatment. The results show that material choice matters. Fabric ducts have lower CO2 emissions and a smaller overall environmental footprint than galvanized steel ducts. In contrast, glass wool ducts lead to higher CO2 emissions because they need to be replaced more often. These findings can guide more sustainable material choices for ventilation in commercial buildings.
