Abstract [en]

Brf Viva is an apartment building, housing society, planned for Gothenburg where one alternative for the façade and house structure is based on wood. The buildings have 6-8 floors with balconies on one or more sides, according to images in the prospectus from Riksbyggen 2014.

By utilizing Report TVBK-3066 [1] (ISSN 0349-4969, ISBN 978-91-87993-01-5) from Lund Technical University and from there in published data, lifetimes of different wooden details of planned buildings, and their maintenance intervals, have been estimated and summed in this report.

Details calculated consists of:

 Protected wood panel and topographically sheltered position and protection by buildings (A1)

 Protected wooden panel and unprotected position (A2)

 Wooden panel without roof overhang with topographically sheltered position and protection by buildings (B1)

 Wooden panel without roof overhang and unprotected position (B2)

 Protected wooden exterior corridor and balcony plate decking (C1). This detail is missing in the guide [1] and its results are therefore considered much more uncertain. Exposed wooden railings on the balcony with topographically sheltered position and protection by buildings (D1)

 Exposed wooden railings on balcony with unprotected position (D2)

The calculated estimates of wooden details life expectancy varied between 12 and 38 years.

Calculating other than those in the report TVBK-3066 [1] described facade panels should be seen more as an attempt to calculate and appears to yield unreasonably short life spans. Calculations on the exterior corridor (C1) is here only to illustrate the inability of the calculation model for the specific example above.
