Economic performance of heating systems for energy renovation of wooden dwellings in Norway
(Master thesis, 2022)Etter at Norge sluttet seg til i Parisavtalen i 2015, ble det satt som mål å redusere landets klimagassutslipp med 50 til 55 %, sammenlignet med 1990-nivået, innen 2030 [1]. Det ble derfor i 2016 vedtatt at energibruken ... -
Economic savings linked to future Arctic shipping are at odds with climate change mitigation
(Journal article; Peer reviewed, 2016)This paper assesses costs, emissions, and climate impact by freight shipping in the Arctic with main focus on the Northern Sea Route. The entire route lies in Arctic waters, which due to global warming, has become ice free ... -

Ecotoxicity effect factors for plastic additives on the aquatic environment: New approach for life cycle impact assessment
(Peer reviewed; Journal article, 2023) -
An effect factor approach for quantifying the entanglement impact on marine species of macroplastic debris within life cycle impact assessment
(Peer reviewed; Journal article, 2019)Plastic waste from anthropogenic activities is accumulating in the marine environment and poses a threat to marine biodiversity. Nevertheless, tools to assess the potential ecosystem damage from plastic waste are currently ... -
Effect factors for marine invasion impacts on biodiversity
(Journal article; Peer reviewed, 2024)Purpose Marine vertebrate populations have halved in the past decades, and invasive species are a major driver for this loss. While many model the spread of invasive species, a model to assess impacts of marine invasions, ... -
Effect of additives in reducing ash sintering and slagging in biomass combustion applications
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:254, Doctoral thesis, 2012)The objective of this study was to investigate sintering and slagging behaviors of biofuels during combustion processes. Biofuels tested are derived from the agricultural sector, wood and furniture industry as well as from ... -
Effect of an Azimuthal Mean Flow On the Structure and Stability of Thermoacoustic Modes in an Annular Combustor Model with Electroacoustic Feedback
(Peer reviewed; Journal article, 2020)Thermoacoustic oscillations in axisymmetric annular combustors are generally coupled by degenerate azimuthal modes, which can be of standing or spinning nature. Symmetry breaking due to the presence of a mean azimuthal ... -
Effect of anion exchange ionomer content on electrode performance in AEM water electrolysis
(Journal article; Peer reviewed, 2020)Anion exchange membrane water electrolysis (AEMWE) has acquired substantial consideration as a cost-effective hydrogen production technology. The anion ionomer content in the catalyst layers during hydrogen and oxygen ... -
Effect of Atmospheric Stability on Meandering and Wake Dynamics
(Master thesis, 2023)Denne studien undersøker effekten av atmosfærisk stabilitet på strømningsdynamikken bak vindturbiner, med fokus på "wake deflection" og "wake meandering". Numeriske Large-Eddy simuleringer med en "Actuator Line" modell ... -

The effect of building attributes on the energy performance at a scale: an inferential analysis
(Peer reviewed; Journal article, 2022)The commitments to mitigate the negative impacts associated with final energy use stipulate the increase of energy efficiency of the built environment. This is the focus of urban energy policies and of built stock energy ... -
Effect of design specifications for off-design operation of low temperature Rankine cycles using zeotropic mixtures and pure working fluids
(Master thesis, 2018)Using organic Rankine cycles to produce power from low temperature heat sources seems like a promising solution to lower our reliance on environmentally damaging energy sources. By introducing this technology to new and ... -
Effect of energy standard on energy and materials use intensity associated with GHG emission from building envelope in U.S. office buildings
(Master thesis, 2021)Studies have shown that the existing building stocks consume about 40% of the energy and resources around the world. They are also responsible for one-third of the total global greenhouse gas (GHG) emissions. Commercial ... -
Effect of excess charge carriers and fluid medium on the magnitude and sign of the Casimir-Lifshitz torque
