Sustainable high-rise residential buildings to be built in central Pudasj\u00e4rvi from logs<\/h1>\n

In autumn 2021, two hybrid buildings made from local logs will be completed in the centre of Pudasj\u00e4rvi. Logs are a healthy and ecological construction material whose carbon footprint is small, not least thanks to sustainable production. It is believed that the use of logs will increase in large construction projects.<\/strong><\/p>\n

Sweco\u2019s structural designers are involved in designing the high-rise residential buildings made from logs, which will be completed in the centre of Pudasj\u00e4rvi by Pudasj\u00e4rven Vuokratalot Oy in autumn 2021. The main contractor of the project is Rakennusliike Lapti Oy.<\/span>\u00a0<\/span><\/p>\n

\u201cThese are hybrid buildings whose load-bearing frame will be made from concrete elements and the external envelope, fa\u00e7ade and some of the adjoining walls will be made from locally sourced logs,\u201d says Sweco\u2019s structural engineering specialist\u00a0<\/span>Marko Karkulehto<\/span><\/strong>.<\/span>\u00a0<\/span><\/p>\n

The design of the nearly 9.5-million-euro project has paid special attention to moisture management and protecting the logs during construction. Data modelling was used to support the design process. \u201cIt has eased risk management and work supervision both in production and on site,\u201d says Lapti\u2019s project development manager for northern Finland\u00a0<\/span>Tapio Ronkainen<\/span><\/strong>.<\/span>\u00a0<\/span><\/p>\n

\u00a0<\/span><\/p>\n

The data model has also been a valuable tool for log manufacturer Kontiotuote. \u201dThe hybrid model provided the initial data for further design of the openings in the logs and enabled us to transport data directly to the machine in our log factory,\u201d says B2B Business Director\u00a0<\/span>Hanna Haipus\u00a0<\/span><\/strong>from Kontiotuote.<\/span>\u00a0<\/span><\/p>\n

Massive logs are ideal for large buildings<\/span><\/strong>\u00a0<\/span><\/p>\n

Traditionally, logs were used to build holiday homes and one-family houses, and in Finland, one in four detached houses is made from logs. Kontiotuote\u2019s\u00a0<\/span>WoodHow<\/span><\/em>\u00a0has a reputation of being the best in the world, but Hirsihovi has still been a learning experience for everyone involved.<\/span>\u00a0<\/span><\/p>\n

\u201cIt was our task to marry concrete and log structures as well as production boundary conditions to create a sensible and cost-efficient building,\u201d Karkulehto says.<\/span>\u00a0<\/span><\/p>\n

Acoustics proved one of the challenges, as noise has traditionally only been managed horizontally in log houses. In a high-rise residential building, noise may not travel between floors. \u201cCreating new solutions was a matter of having the right attitude and required that all parties allocate time for product development,\u201d Ronkainen emphasises.<\/span>\u00a0<\/span><\/p>\n

\u201dTogether with construction professionals and structural engineers, we were able to create a success story!\u201d Haipus says with a smile.<\/span>\u00a0<\/span><\/p>\n

A healthy and ecological building material<\/span><\/strong>\u00a0<\/span><\/p>\n

In Finland\u2019s log capital Pudasj\u00e4rvi, log is the building material of choice. Pudasj\u00e4rvi already has an impressive log campus that has attracted visitors from all over the world. The fa\u00e7ade of Hirsihovi in Pudasj\u00e4rvi is made of SmartLogs by Kontiotuote, which do not settle as they dry. They act as sufficient insulation on their own \u2013 even in the event of fire.<\/span>\u00a0<\/span><\/p>\n

\u201dAccording to building regulations, large logs can be used for any structures,\u201d Haipus says. In addition to this, logs also have an excellent ability to bind and release moisture, which makes for high-quality indoor air. \u201dThis makes logs a very attractive material for housing companies, as well.\u201d<\/span>\u00a0<\/span><\/p>\n

Log buildings also serve as carbon stock, which is why log construction is often associated with an ecological carbon handprint rather than a carbon footprint. \u201dChoosing logs is not a small, but a big action to take for the environment,\u201d Haipus notes.<\/span>\u00a0<\/span><\/p>\n

Sustainable production makes logs an even more eco-friendly construction material. The Kontiotuote log factory produces more energy than it consumes, because the residual resources of production, such as woodchips and sawdust, are utilised in local district heating production, for example. The carbon footprint of a log house will not increase even due to transportation. \u201dAll of the logs are sourced from responsible forest owners within a roughly 100-kilometre radius,\u201d Haipus says.<\/span><\/p>\n
