    • Grønne tak som LOD- og miljøtiltak 

      Hanslin, Hans Martin; Johannessen, Birgitte Gisvold (NIBIO Rapport;, Research report, 2018)
      Grønne tak kan bidra med mange økosystemtjenester og funksjoner som å holde tilbake og fordrøye nedbør på tak, fremme biologisk mangfold, estetikk osv., inkludert nye trender som takhager og urbane uterom, dyrking av mat ...
    • Investigating the use of extensive green roofs for reduction of stormwater runoff in cold and wet climates 

      Johannessen, Birgitte Gisvold (Doctoral theses at NTNU;2019:99, Doctoral thesis, 2019)
      Urban development, with the introduction of piped drainage systems and increase in impervious surfaces, have altered the natural runoff patterns severely. This has resulted in increased risks of flooding and damages, and ...
    • Modelling detention performance of green roofs in cold climates 

      Russwurm, Ingrid Lindberg (Master thesis, 2018)
      Green roofs (GRs) have become a popular sustainable drainage system (SuDS) technology in urban areas. As many countries and regions experience political encouragement and substitution schemes in implementing GRs, there is ...

    • Modelling of a Combined Infiltration and Detention Solution with Investigation of System Performance 

      Vartdal, Anette (Master thesis, 2021)
      Befolkningsvekst og urbanisering i kombinasjon med global oppvarming er drivende faktorer for utviklingen av et nytt tankesett innen overvannshåndtering. De eksisterende konvensjonelle avløpssystemene strekker ikke til i ...
    • Oppfølging grønne tak fra Fremtidens byer, 2016 

      Hanslin, Hans Martin; Johannessen, Birgitte Gisvold (NIBIO Rapport;, Research report, 2016)
      Grønne tak demper og fordrøyer avrenning etter nedbør og er etablert som et tiltak for lokal overvannsdisponering. I prosjektet Fremtidens Byer, ble det i 2014 etablert forsøkstak med utprøving av ulike tekniske løsninger ...
    • Temperatures and precipitation affect vegetation dynamics on Scandinavian extensive green roofs 

      Lönnqvist, Joel; Hanslin, Hans Martin; Johannessen, Birgitte Gisvold; Muthanna, Tone Merete; Viklander, Maria; Blecken, Godecke (Peer reviewed; Journal article, 2020)
      Standard succulent vegetation mixes developed mostly in temperate climates are being increasingly used on green roofs in different climate zones with uncertain outcome regarding vegetation survival and cover. We investigated ...
    • Temporal downscaling of IDF curves applied to future performance of local stormwater measures 

      Kristvik, Erle; Johannessen, Birgitte Gisvold; Muthanna, Tone Merete (Journal article; Peer reviewed, 2019)
      Low-impact development (LID) structures are combined with traditional measures to manage stormwater and cope with increased runoff rates originating from heavy urbanization and climate change. As the use of LIDs for climate ...
