Linking Housing Policy, Housing Typology, and Residential Energy Demand in the United States
(Peer reviewed; Journal article, 2021)Residential energy demand can be greatly influenced by the types of housing structures that households live in, but few studies have assessed changes in the composition of housing stocks as a strategy for reducing residential ... -
Linking inventories and impact assessment models for addressing biodiversity impacts: mapping rules and challenges
(Peer reviewed; Journal article, 2022)Purpose An adequate matching between the nomenclature of elementary flows in life cycle inventory (LCI) databases and life cycle impact assessment (LCIA) methods is key for ensuring the proper application of life cycle ... -
Linking marine plastic debris quantities to entanglement rates: Development of a life cycle impact assessment ‘effect factor’based on species sensitivity
(Master thesis, 2019)Etter hvert som produksjon og bruk av plast fortsetter å vokse eksponentielt, øker også andelen «feilbehandlet avfall» som ender opp i naturen. En voksende forskningsgruppe har forsøkt å kvantifisere effekten av dette ... -
Liquefaction Process Evaluation for Floating LNG
(Master thesis, 2013)The gas expander processes have attracted growing interest for FLNG facilities due to utilization of non-flammable fluids i.e. nitrogen as refrigerant and simplicity in configuration and operation. New developments of the ... -
