This research investigates a solar thermal system and a solar photovoltaic system which produces local energy, by incoming solar radiation, to meet the energy consumption demand of a residential building in the arctic region. The study on the use of the solar systems in the arctic areas is rare and often doubted. So, to analyze the potential of solar energy, a study case of an existing building block ...

Oppgaven retter fokus mot hvordan vi tradisjonelt planlegger fremdriften i byggeprosjekter i dag, og hvordan digitale verktøy som 4D BIM klarer å effektivisere planleggingen. I tillegg vil også Lean filosofien befinne seg i ulike planleggingsmetoder, man ønsker å skape verdi både for selskapet, kundene og alle andre deltakere som er involvert i prosjektet. Dermed ønsker man å skape flyt i produksjonen ...

Heat engines, such as internal combustion engines, have significant adverse effects on the environment due to their heat and harmful emissions. In addition, they are dependent on energy from fossil resources, which are depleting rapidly and they are not being properly utilized due to the relatively low efficiency of heat engines usually expressed by Carnot's efficiency. The low temperature direct ...

The concept of Green Building refers to environmentally friendly constructions with the target of minimizing the impact on the natural environment through sustainable and efficient use of resources over their life cycle. Since modern buildings are large contributors to global energy consumption and greenhouse gas emissions, policies and international strategies intended to reduce the carbon footprint ...

Green Buildings are defined as environmental-friendly buildings aimed at minimizing the impact on the natural environment through a sustainable and efficient use of resources over their life-cycle. This is, perhaps, a recently-introduced building concept that is increasingly gaining attention due to the policies and strategies intended to reduce the carbon footprint of conventional buildings, which ...

Inquiry-based methods have been seen as important for developing science in school. There are good reasons why the work of designing various technological devices in technology should also be part of inquiry-based methods. If so, it requires that the teachers have an exploratory approach in communicat-ing with students. In this paper, we analyze the communication between teachers and students in six ...

Tilsetting av fiber i betong har vært noe som lenge har vært benyttet for å tilføre strekkegneskaper i betongen og hindre blant annet riss i betongen. Det har i de siste årene vært et ønske om å undersøke om det er forsvarlig å bruke fiber betong i bærende konstruksjoner, og ikke kun i fundamenter og sprøytebetong som fiber har normalt sett vært benyttet til. Etter publiseringen av NB.38 i 2020 har ...

Renewable energy technologies are becoming widely integrated into energy generation systems around the world. While the majority of such technologies are integrated at a large scale in the form of wind and solar farms, there is a need for their incorporation into the built environment. A university campus is an ideal place for testing and understanding how renewable energy technologies can be ...

While design optimization of buildings seeks to improve energy efficiency and, thus, leads to greenhouse gas emissions reduction, the thermal performance of buildings can be compromised. Thermal performance is an important aspect as it directly affects the health and wellbeing of occupants. This study aims to investigate using a simple simulation tool to examine the correlation between a set of ...

A The innovative idea of utilization of iron ore dust (IODust), characterized by red hue typical for Narvik, came up during designing artwork for The Arctic University of Norway campus Narvik. The use of waste from iron ore production as a natural pigment was completed by partial replacement of natural aggregates (NA) by recycled concrete aggregates (RCA) to achieve a higher level of material ...
