The aim of this study is to compare the life cycle costs (LCC) and energy performance of different heating and ventilation systems (HVAC) in deep-energy renovation of Norwegian detached houses. More specifically, the relative performance of nine different HVAC combinations based on heat pumps is compared...
Propellers are a vital component to achieve successful and reliable operation of drones. However, the drone developer faces many challenges while selecting a propeller and a common approach is to perform static thrust measurement. However, the selection of a propeller using a static thrust measurement...
The visual appearance and mechanical properties of aluminium alloy extrusions are strongly dependent on the microstructure and texture of the extruded profiles, where the desired microstructure and texture may depend on the specific applications. In the present work, the evolution of deformation as well...
...climate change is regarded as a major global challenge, and the de-carbonization of the energy sector requires a massive transformation that involves an increase of renewable shares in the energy mix and the incorporation of carbon capture and storage (CCS) processes. Given all this strong new momentum...
...is performed and the energy consumption for different systems is compared. The components of the heat pump (evaporator, compressor, 2 condensers, expansion valve and controller) were dimensioned for a 250 kW (thermal) system and a drying model based on the similarity between heat and mass transfer...
Overall the activities in 2011 have developed satisfactorily and in accordance with the project schedule. The wildlife and power-line corridor subproject is focusing the moose habitat use of the clear-felled area beneath a selected transmission-line section in Bangdalen, Nord-Trøndelag County. Existing...
...new opportunities for studying electricity consumption patterns. Measurement of end-uses on appliance level remains however to be very time consuming and expensive, so the possibility to model segmented end-use demand based on metering of total electricity consumption is essential. The paper presents...
LNG infrastructures and gas pipeline projects, by using data relating to projects whose financial close occurred between June 2004 and March 2011. Most results are consistent with the basic view of risk-averse funds suppliers. Especially, the projects located in risky countries and larger projects tend...
