As its award criteria, the jury stated the following:
Joensuu Lighthouse is Finland's first 14-storey wooden apartment block. Rising to almost 50 metres, this student dormitory can be considered a pioneer in the development of high-rise wood construction that also attracts international interest.
To make the project possible, various aspects of wood construction solutions and processes needed further development. The fire safety design for the building is based on case-specific functional fire design, as the standard dimensioning tables only cover buildings up to 8 storeys high. From a structural point of view, the site was classed as exceptionally demanding. The structure is stiffened with steel rods inside the wooden structures, tensioned from top to bottom. This is the first time this technology has been applied in Finland.
The project used a competitive negotiation process, with the final choice being Stora Enso's frame system and local construction contractor Eero Reijonen Oy. The site exemplifies the compatibility of different wood products with its use of both LVL veneer and CLT cross-laminated plywood. A total of more than 2,000 m3 of solid wood products were delivered to the site. The wood product components store carbon in an amount equivalent to the annual carbon dioxide emissions of about 700 passenger cars.
The building was completed on schedule. Each individual storey took less than two weeks to build. The solid wood panel blanks were delivered to the site with the necessary window and door openings and conduits for building services in place, all machined by Timberpoint Oy of Loviisa. The final touches needed for installation were added under the cover of a tent. The elements were installed when the weather permitted, and after installation, the completed storeys were protected by a temporary roof to maintain the dry chain.
Lighthouse Joensuu will continue to promote wood construction as Karelia University of Applied Sciences will continue acoustics research and monitor the effects of variations in temperature and humidity, including structural displacement and creep. The apartment building exhibits the light artwork of lighting artist Kari Kola. The permanent installation employs an exceptional technique where the lightwork glows out of the building.

In selecting the winner of the Wood Award, the jury pays special attention to the architectural quality of the site, the innovative use of wood and the overall attention attracted by the site.
The 2019 jury consisted of Puulehti's Editor-in-Chief Mikko Viljakainen and writers Hilppa Iittiläinen and Kirsi Pellinen. The jury enlisted the expert opinion of Markku Karjalainen, Architect and PhD Eng., who is the Professor of Civil Engineering at the University of Tampere's Department of Architecture.
