Oppgaven skal undersøke langsiktig effekt av energifokus for Quality Hotel Harstad, som er prosjektert etter Byggteknisk forskrift (TEK17). Energiberegningsverktøyet SIMIEN er anvendt for å analysere energibehovet til hotellet, og kartlegge hvilke energibesparendetiltak som gir høyest effekt. Hovedmålet er å vurdere hvilke tiltak som bør iverksettes for å heve hotellets energiklasse fra B til A i ...

Sammendrag I forbindelse med Lurøy kommunes sterke fokus på enøk ønsker de å se hvilken nytte ulike tiltak kan ha på eksisterende bygg. Størsteparten av bygningsmassen til Lurøy kommune er fra 1960- til 1980-tallet. Flere av FNs bærekraftsmål er aktuell for oppgaven. Strøm, fremtidig utsikt for energipris, miljø, resirkulering, gjenbruk og oppgradering av eksisterende boliger og begrense sløsing ...

Arbeidsproduktiviteten i bygg- og anleggsnæringen i Norge fortsetter med en negativ trend, samtidig som byggekostnadsindeksen for nybygg stiger. Næringsaktører identifiserer et betydelig forbedringspotensial i bransjen. Flere peker på standardisering og prefabrikasjon som en del av løsningen. Consto Nord har bred erfaring med bruk av prefabrikkerte ytterveggselementer, både ved innkjøp og egen ...

Crystallographic aspects of heterogeneous plastic flow during ductile tearing are assessed experimentally by combining in situ synchrotron laminography imaging of notched flat samples with a full-field measurement technique and numerical simulations with the crystal plasticity finite element method (CP-FEM). Advantage is taken of the plane strain condition in the region ahead of the notch root (i.e., ...

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 ...

The rapid oxidation of carbon black (CB) is a major drawback for its use as a catalyst support in polymer electrolyte fuel cells. Here, we synthesize poly[2,20 -(4,40 -bipyridine)-5,50 -bibenzimidazole] (BiPyPBI) as a conducting polymer and use it to functionalize the surface of CB and homogenously anchor platinum metal nanoparticles (Pt-NPs) on a CB surface. The as-prepared materials were ...

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 ...

While designing the power requirements of a ship, the most important factor to be considered is the ship resistance, or the sea drag forces acting on the ship. It is important to have an estimate of the ship resistance while designing the propulsion system since the power required to overcome the sea drag forces contribute to ‘losses’ in the propulsion system. There are three main methods to calculate ...

In this paper, the inhibitory effects of added hydrogen in reactor headspace on fermentative hydrogen production from acidogenesis of glucose by a bacterium, Clostridium acetobutylicum, was investigated experimentally in a batch reactor. It was observed that hydrogen itself became an acute inhibitor of hydrogen production if it accumulated excessively in the reactor headspace. A mathematical model ...

Missing or incomplete documentation for management, operation, and maintenance can become a problem in relation to both cost and quality. This thesis presents demands and responsible roles in given such documentation and uses the new standard SN/TS 3456:2018 Documentation for management, operations, maintenance and development (FDVU-documentation) to prepare a checklist/control-form for this ...
