Fully nonlinear phase-resolved wave modelling in the Norwegian fjords for floating bridges along the E39 coastal highway
(Peer reviewed; Journal article, 2023)Coastal wave conditions are highly influenced by bathymetry variations and coastlines. The Norwegian fjords present large gradients of bathymetry changes and irregular coastline geometries that make the understanding of ... -
Non-target and suspect screening reveal complex pattern of contamination in Arctic marine zooplankton
(Peer reviewed; Journal article, 2023)Although increasing, there is still limited knowledge of the presence of ‘contaminants of emerging concern’ in Arctic marine biota, particularly in lower trophic species. In the present study, we have applied a novel ... -
BREEAM Communities and ZEN Definition at a glance. A qualitative comparison and what we can learn
(ZEN Memo;56, Research report, 2024)Learning across BREEAM Communities and ZEN definition A significant effort in ZEN has been put into defining what to measure to define a neighbourhood as ‘zero emission’ through the identification of assessment criteria ... -
Sustainability within food cold chain sectors in Norway
(Chapter, 2023)Food processing, storage, and distribution demand a considerable amount of energy and raw materials. Processes that are especially energy demanding includes cooling, freezing, drying and heating, but they are also necessary ... -
Reducing cold chain GHG emissions in Norwegian fish and meat industry sectors
(Chapter, 2023)The food chain represents a climate impact of major concern as it is a significant source of greenhouse gas (GHG) emissions. Norway has a long coastline with perfect conditions for salmon farming and well-established ... -
Study on retaining natural refrigerant in seafood processing industries in India
(Chapter, 2023)In the seafood processing sector in India, natural refrigerant such as NH3 is currently replaced by Freon refrigerants such as HFC-404A, because these systems are comparably more compact, operate above atmospheric pressure ... -
Integrated CO2 refrigeration and heat pump system for a dairy plant: Energy analysis and potential for cold thermal energy storage
(Chapter, 2023)Dairy processing is considered very energy-intensive due to significant thermal demands for both cooling and heating at different temperature levels. Conventional dairy plants have separate systems for supplying the various ... -
Numerical investigation of an ammonia-water absorption-compression high-temperature heat pump for hot water and steam production in food processing
(Chapter, 2023)To achieve climate neutrality in the food sector, there is an urgent need for eco-friendly steam boilers. The absorption-compression heat pumps (ACHP) using an ammonia-water mixture as working fluid can provide a high heat ... -
Investigation and analysis of a CO2 heat pump chiller with novel two-stage evaporator
(Chapter, 2023)This study was carried out to investigate the performance of a transcritical CO2 heat pump chiller that provides heating and cooling simultaneously. There are several applications where such CO2 systems are implemented, ... -
Systematic review: Upscaling energy retrofitting to the multi-building level
(Peer reviewed; Journal article, 2024)Retrofitting the building stock is pivotal to achieving climate neutrality by 2050. Most of the existing research on energy efficiency focuses on new residential buildings. The focus must shift to multi-building retrofits, ... -
Demonstrating the load-shifting potential of a schedule-based control in a real-life educational building
(Peer reviewed; Journal article, 2024)This work investigates the potential of simplified control approaches to deploy the building energy flexibility (BEF), here for the shifting of the space-heating load in a real-life educational building. The educational ... -
Impact of practical challenges on the implementation of data-driven services for building operation: Insights from a real-life case study
(Peer reviewed; Journal article, 2024)Data-driven applications in buildings using AI and machine learning have generated a lot of interest, but scaling these applications is challenging due to the uniqueness of each building. During the process of implementing ... -
