Det er mest energi å spare i de husene som allerede er bygget, og etterisolering av den eldre bygningsmassen er blant de mest effektive tiltakene....

Ved å forutsi det faktiske oppvarmingsbehovet i et bygg kan man spare mye energi....

A risk assessment methodology is developed to analyse the impact of natural hazards on cultural heritage objects. The methodology involves both qualitative and quantitative risk analysis approaches. In the qualitative risk analysis, probability and consequence classes based on NS 5815 are used...

Four surrogate modelling techniques are compared in the context of modelling once-through steam generators (OTSGs) for offshore combined cycle gas turbines (GTCCs): Linear and polynomial regression, Gaussian process regression and neural networks for regression. Both fully data-driven models and...

As an integral part of the Norwegian full-scale CCS project Longship, the Northern Lights joint venture owned by Equinor, Shell and Total, is responsible for transporting liquified CO₂ by ship from the industrial capture sites in the south-eastern part of Norway to an onshore terminal located on the...

Combined cycle gas turbine plants (CCGTs) fulfill an important role in emission reduction of offshore power systems as the bottoming cycle (BC) produces additional power from exhaust heat of the gas turbines (GTs). With increasing integration of wind turbines, CCGTs offshore must be flexible and...

A comprehensive waste composition analysis was undertaken in 2021, covering ten municipal waste companies in Central Norway. The results are used in a multiple linear regression model to explore factors influencing the municipal solid waste sorting behaviour. The aim of the study is to better...
