Wind engineering

Climatic extremes on communications towers
Customer: Telenor
Location: Norway
Many communication towers have seen increased antennae-construction in line with technical developments.These new installations are likely to have reduced the towers’ resistance to icing and wind loads. Telenor would thus like to update the load calculations for their towers. Kjeller Vindteknikk will deliver expected extreme values of wind and icing for up to 2000 communication towers.

 

Sandsfjord bridge
Customer: Statens Vegvesen Region Vest
Location: Åsarødholmen, Suldal Kommune, Rogaland, Norway
Kjeller Vindteknikk has been commissioned to measure wind and turbulence at 60m height, as well as to carry out analyses of extreme winds and the spectral distribution of turbulent energy.

 

Bjørvika - Urban wind conditions
Customer: HAV Eiendom, Bjørbekk & Lindheim
Location: Oslo, Norway
Expansion of Bjørvika will affect the local wind conditions. Kjeller Vindteknikk has assessed the wind conditions for the planned Munch Museum and Deichman Library, as well as the surrounding buildings. Frequency of wind in different speed classes and exceedance of comfort criteria were calculated for the Munch Museum.

 

Analysis of meteorological conditions for possible airport locations in the Faroe Islands
Customer: Landsverk
Location: Glyvursnes and Søltuvik, Faroe Islands
Kjeller Vindteknikk has been commissioned to analyze wind and turbulence conditions, as well as visibility and cloud-heights for two possible locations of a new airport in the Faroe Islands.

 

Wind and climate conditions in Oslo
Customer: Plan- og bygningsetaten
Location: Oslo, Norway
Kjeller Vindteknikk has conducted an assessment of the wind and climate conditions in the new area Filipstad planned in central Oslo. Computational fluid dynamic simulations (CFD), combined with climate data from a numerical weather model, have been used to determine the future wind conditions in the area. The end product is an estimate of the area’s future wind comfort. The wind comfort levels are used as guidance by the architects in the planning and design of the new buildings and roads in the area. The results of the assessment are also useful in determining the suitability of different places for distinct purposes, such as cafés, benches, playgrounds, walkways and bike paths etc.
