Temaområde Miljøsystemanalyse
Oppgavenr: MSA1
Tittel: Environmental impact assessment of concrete structures used in infrastructure projects.
Tilknyttede emner: TBA4171 - Bygnings- og materialteknikk, videregående kurs
Bakgrunn:
Infrastructure projects consumes a large volume of concrete, and cement production alone contributes to more than 5% of annual anthropogenic greenhouse gas emissions.
The strength of concrete structures varies with a number of variables, among them curing time. Normally we use the strength after a curing time of 28 days as the design criteria.
Kort beskrivelse av oppgaven:
In this project, we seek a better understanding how variations in curing time would influence design of concrete structures (volume), and thus environmental impact of concrete for various purposes in infrastructure projects.

Oppgavenr: MSA2
Tittel: LCA of construction machinery
Tilknyttede emner: TBA4171 - Bygnings- og materialteknikk, videregående kurs, TBA4151 Anleggsteknikk, videregående kurs
Bakgrunn:
How we use machineries in construction projects has a huge impact on greenhouse gas emissions from these projects. At the department or Civil and Environmental Engineering, we have a huge empirical dataset on costs and fuel consumption from numerous construction machines for different types of loads and work. However, this needs to further developed to also include environmental impact (LCA).
Kort beskrivelse av oppgaven:
We need a motivated student to work develop LCA on construction machinery

Tittel: LCA of Tunnel Boring Machines (TBM)
Tilknyttede emner: TBA4171 - Bygnings- og materialteknikk, videregående kurs, TBA4151 Anleggsteknikk, videregående kurs
Bakgrunn:
Tunnels and underground spaces is important in the development of more sustainable cities. However, so far there is few studies of the environmental impact from using tunnel-boring machines. At the department or Civil and Environmental Engineering, we have some data on costs and fuel consumption from tunnel projects machines for different types of tunnel-boring. We are also in contacts with ongoing tunnel projects.
Kort beskrivelse av oppgaven:
We need a motivated student to work on LCA of tunnels made with TBMs.

Tittel: Environmental impact of geometric design of roads
Tilknyttede emner: TBA4171 - Bygnings- og materialteknikk, videregående kurs
Bakgrunn:
The geometric design of roads have a strong impact on energy consumption of road traffic. At the department of Civil and Environmental Engineering, we have an ongoing project in cooperation with Chalmers and SVV (E39) on understanding the environmental impact from the roads geometric design. How much should we try to modify curves and elevations in order to optimize/reduce the total environmental impact from roads and traffic? How will a shift in technology from fossil to renewable energy for vehicles influence these calculations?

Oppgavenr: MSA5
Tittel: Life cycle assessment of winter maintenance operations in Norway
Tilknyttede emner: TBA4171 - Bygnings- og materialteknikk, videregående kurs
Bakgrunn:
In Norway, there are 55.000 km of national and state roads that need different type of maintenance and service, including winter maintenance. The driving distance of the clearing vehicles for winter maintenance was over 19 million kilometers in 2013. I in addition 188.000 tons of salt and 575.000 tons of sand was used during winter maintenance.
At the department of Civil and Environmental Engineering, we have an ongoing project in cooperation with Chalmers and SVV (E39) on understanding the environmental impact from the winter maintenance operations.
