| description | One of the environmental issues facing today’s society is the increased emission
of greenhouse gases, such as carbon dioxide, from urbanization. There is a need of
innovative solutions to that problem and this thesis aim to evaluate sedum green
roofs ability to yearly carbon sequestration and evaluate if it could reduce the effect
of urbanization on climate change.
Another aim is to analyse the impact of air temperature and the medium’s moisture
content on carbon sequestration at different light levels. The potential of sedum
roofs to sequester carbon was estimated using light response functions established
from carbon dioxide (CO2) exchange measurements in climate chambers and scaled
up to a yearly value using data of air temperature and photosynthetically active
radiation (PAR) Uppsala 2013. The result showed that sedum roof sequesters 45 g
C m-2 year-1. Put in relation to prior studies about carbon sequestration the amount
is low, but if other positive aspect of sedum roof such as it´s ability to isolate rooftops,
which indirect reduces the emissions of green house gases, is encountered it is
a good solution for urban environments. The fact that the alternative roofs such as
tile roof, felt roof and tin roof do not sequester any carbon dioxide shows sedum
roofs potential of being a great solution to reduce greenhouse gases in urban areas. |

Ett av de stora miljöproblem samhället står inför idag är de ökade emissioner av växthusgaser, såsom koldioxid, som kommer av urbanisering. Det finns ett behov av innovativa lösningar för att lösa detta problem och den här studien syftar till att studera sedumtaks potential att lagra in kol på årsbasis och att bedöma om de kan bidra till minskad klimatpåverkan. Ytterligare syfte är att analysera hur lufttemperatur och substratets fuktighet påverkar koldioxidutbytet vid olika ljusnivåer. Sedumtaks potentiella årliga koldioxidupptag skattades från ljusresponsfunktioner som baserades på koldioxidutbytesmätningar av sedumtak i klimatkamrar och skalades upp till ett årsvärde med klimatdata över lufttemperatur och fotosyntetisk aktiv strålning (PAR) från Uppsala år 2013. Resultatet visade att sedumtak lagrar in 45 g C m-2 år-1. I relation till tidigare studier om kolinlagring är mängden mindre, men vägs andra positiva aspekter in, exempelvis att sedumtak isolerar, vilket indirekt minskar utsläpp av växthusgaser, kan sedumtak vara en bra lösning i urbana miljöer. Det faktum att alternativen tegel-, plåt- och papptak har ett obefintligt nettoupptag av koldioxid visar sedumtaks potential att vara en bra lösning för att minska växthusgaser i urbana miljöer. 2015-10-06 First cycle, G2E NonPeerReviewed application/pdf sv https://stud.epsilon.slu.se/8539/1/taylor_s_151006.pdf Taylor, Sofie, 2015.
