Abstract
Dette kandidatspeciale, udført af studerende i Bygningsenergidesign ved Aalborg Universitet, undersøger tre praktiske aspekter af indendørs luftkvalitet (IAQ). For det første analyserer vi, hvor meget fugt almindelige aktiviteter indendørs producerer over tid, baseret på litteratur og avancerede bygningssimuleringer. For det andet måler vi partikelkoncentrationer i tre danske lejligheder. For at gøre dette designede og samlede vi specialudstyr og udviklede sammen med datalogistuderende et dataopsamlingssystem til partikelsamlere. Over en tre ugers målekampagne beskriver vi, hvordan beboernes adfærd påvirker fine partikler (PM2,5) og grovere partikler (PM10), og vi estimerer beboernes eksponering for partikler. For det tredje undersøger vi, om mikroplastpartikler og -fibre findes i indeluften. En åndende termisk manikin (et apparat, der efterligner kropsvarme og vejrtrækning) blev brugt til at vurdere potentiel eksponering, og universitetspersonale analyserede de indsamlede data med FPA‑µFTIR-billedspektroskopi (en avanceret infrarød billedteknik). Rapporten præsenterer metoder, målinger og resultater fra disse tre undersøgelser.
This master's thesis by Building Energy Design students at Aalborg University explores three practical aspects of indoor air quality (IAQ). First, we analyze how much moisture everyday indoor activities generate over time, using published research and advanced building simulations. Second, we measure particle concentrations in three Danish apartments. To do this, we designed and assembled custom equipment and, together with Computer Science students, developed a data acquisition system for particle samplers. Over a three-week campaign, we describe how occupant behavior influences fine particles (PM2.5) and coarser particles (PM10) and estimate occupant exposure to particulate matter. Third, we investigate whether microplastic particles and fibers are present in indoor air. A breathing thermal manikin (a device that simulates body heat and breathing) was used to assess potential exposure, and university staff analyzed the gathered data using FPA‑µFTIR imaging spectroscopy (an advanced infrared imaging technique). The report presents the methods, measurements, and findings from these three investigations.
