A New Foundation Model for Integrated Analyses of Monopile-based Offshore Wind Turbines
(Journal article; Peer reviewed, 2017)Offshore wind turbines are highly dynamic and tightly coupled systems subjected to variable cyclic loads. Designing and optimizing the support structure is a complex task, where several load scenarios have to be analysed ... -
A review and comparison of floating offshore wind turbine model experiments
(Journal article; Peer reviewed, 2016)Floating off shore wind turbines provide more access to deeper water than conventional fixed bottom wind turbines, which expands the viable area for wind energy development, reduces visibility from shore, and can potentially ... -
A review of slamming load application to offshore wind turbines from an integrated perspective
(Journal article; Peer reviewed, 2017)In harsh sea conditions, it is possible for offshore wind turbines (OWTs) to be exposed to slamming loads due to breaking waves, especially plunging breaking waves. These slamming loads lead to significant structural ... -
Air-Filled Nanopore Based High-Performance Thermal Insulation Materials
(Journal article; Peer reviewed, 2017)State-of-the-art thermal insulation solutions like vacuum insulation panels (VIP) and aerogels have low thermal conductivity, but their drawbacks may make them unable to be the thermal insulation solutions that will ... -
An exergy analysis for Milano smart city
(Journal article; Peer reviewed, 2017)Cities represent fundamental hubs in the world’s energy-flow network, and their role is expected to gain further relevance in the next decades, following the ongoing urbanization process. Reducing energy use and increasing ... -
Climate Adaptation Framework for Moisture-resilient Buildings in Norway
(Journal article; Peer reviewed, 2017)In the next decades, buildings and infrastructure will be exposed to significantly different climatic strains than they are today. Still, building standards and design guidelines presuppose use of historic weather data. ... -
Climate adaptation of buildings through MOM- and upgrading - State of the art and research needs
(Journal article; Peer reviewed, 2017)This study presents an overview of research initiatives and projects addressing climate adaption in management operation and maintenance (MOM) and upgrade of existing buildings. The aim was to identify knowledge needs and ... -
Coupled mooring systems for floating wind farms
(Journal article; Peer reviewed, 2015)In this paper it is investigated if, by coupling the catenary mooring systems of a number of turbines, the number of lines and anchors needed and subsequently the costs could be reduced and what kind of dynamic phenomena ... -

Effect of Load Sequence and Weather Seasonality on Fatigue Crack Growth for Monopile-based Offshore Wind Turbines
(Journal article; Peer reviewed, 2016)Offshore wind turbines are subjected to variable amplitude loading, but the impact of load sequence is commonly neglected in fatigue analysis. This paper presents an initial investigation if load sequence and weather ... -
Exploring the CO2-Impact for Building Height; A Study on Technical Building Installations
(Journal article; Peer reviewed, 2016)Building tall typically requires a different operational energy demand and additional material. The purpose of this article is to analyze the adaption of technical systems to increased building height with particular ... -
Fatigue crack detection for lifetime extension of monopile-based offshore wind turbines
(Journal article; Peer reviewed, 2017)Lifetime extension becomes increasingly crucial for industry, since the first offshore wind farms face the end of their design lifetime. The remaining useful lifetime of offshore foundations is driven by fatigue design and ... -
Feasibility Study of Novel Integrated Aerogel Solutions
(Journal article; Peer reviewed, 2017)The market share for fibre reinforced aerogel insulation materials is expected to increase as production costs are lowered, and in this context, the development of layered products with integrated aerogel is highly ... -
High-Rise Timber Buildings as a Climate Change Mitigation Measure - A Comparative LCA of Structural System Alternatives
(Journal article; Peer reviewed, 2016)This paper reports on a study examining the potential of reducing greenhouse gas (GHG) emissions from the building sector by substituting multi-storey steel and concrete building structures with timber structures. Life ... -
Impact of urban density and building height on energy use in cities
(Journal article; Peer reviewed, 2016)Compact cities have been attributed to lower per capita energy use. However, the complexity of relationships between the elements that constitute energy consumption in the urban system is poorly understood. Little or no ... -
Influence of Soil Parameters on the Fatigue Lifetime of Offshore Wind Turbines with Monopile Support Structure
(Journal article; Peer reviewed, 2016)Designing support structures for offshore wind turbines is a complex task as these are highly dynamic systems subjected to long-term cyclic loads with variable amplitude. Long-term cyclic loading may cause stiffening or ... -
