Satavuo School in Laukaa has become the ecological centre of the entire village<\/h2>\n

Satavuo School in Laukaa serves as an example for Finnish wooden schools and ecological construction.\u00a0The new school, which combines three village schools, has grown into a centre for the entire village and a beacon for an ecological lifestyle.\u00a0Sweco was in charge of the school\u2019s structural and building services engineering.<\/p>\n

Implemented as a project management contract, Satavuo School became the most ecological school building in Finland upon completion. The cosy and healthy new school was made available to preliminary school, preschool and day care children from three villages in 2018. The school has gradually become the centre of the entire village, around which low-carbon housing and sustainable business is being planned.<\/p>\n

\u201cThe school has been welcomed with open arms, and the occupants are particularly pleased with the building itself as well as the selected materials and technical solutions,\u201d says\u00a0Jukka V\u00e4h\u00e4s\u00f6yrinki<\/strong>, Development Engineer for the Municipality of Laukaa. \u201cIn addition to this, the building has become an ecological example in the region.\u201d<\/p>\n

Adaptability in practice<\/h3>\n

Sweco was in charge of the school\u2019s structural and building services engineering. The open, well-lit and easily-modifiable spaces were constructed in a modular fashion. \u201cThis means that the school can adapt to a variety of uses over the coming decades, both in terms of teaching and other activities in the evenings,\u201d says\u00a0Heljo Hakulinen<\/strong>, Sweco\u2019s design director for HVAC and automation technology.<\/p>\n

The concept of adaptability has already been realised in practice. \u201cWe divided one space into two in a cost-efficient manner, which was possible thanks to careful planning in advance,\u201d V\u00e4h\u00e4s\u00f6yrinki says. In the design phase, it was ensured that any modifications and adjustments to electrical, ventilation and structural engineering solutions could be easily implemented, in case of a need to divide spaces, for example. \u201cThe building will most certainly expand in the future, since the school\u2019s capacity is already in full use.\u201d<\/p>\n

The school\u2019s staff and pupils, village residents and municipal residents were listened to carefully in designing the school. One of the most important goals was to ensure that the premises were comfortable and healthy for all occupants. \u201cThis is why the \u2018Terve talo\u2019 criteria were used for moisture management, and the highest possible P1 category was applied to cleanliness control during construction,\u201d Hakulinen says.<\/p>\n

\u201cAnother goal was to utilise industrial wood construction as much as possible and design a versatile building that will stand the test of time for the next 100 years,\u201d adds\u00a0Jouko Rossi<\/strong>, Sweco\u2019s department manager for structural engineering.<\/p>\n

Energy calculation to compare CLT and log<\/h3>\n

Satavuo School was built from CLT Finland Oy\u2019s (Hoisko) CLT solid wood, for which the raw material is PEFC-certified Finnish wood. However, the school was originally designed as a log building. Sweco\u2019s experts conducted multiple energy and life-cycle calculations. \u201cThe first calculations on the optimal positioning of the ventilation machine rooms were already included in the building\u2019s spatial model,\u201d says Sweco project manager\u00a0Juho K\u00e4\u00e4ri\u00e4inen<\/strong>.<\/p>\n

As the design process progressed, energy consumption calculations were also conducted to compare log and CLT. The variables were the exterior wall\u2019s thermal transmittance (U value) and both wood materials with and without insulation. The comparison was used to put together a table that indicates the total energy consumption. \u201cCLT elements turned out to be the superior choice in terms of life-cycle costs and energy efficiency,\u201d K\u00e4\u00e4ri\u00e4inen says. \u201cOutdoor air leaks through the CLT wall are nearly non-existent.\u201d<\/p>\n

Seamless cooperation in structural and technical engineering<\/h3>\n

Many new solutions were created in order to make the solid wood work as the school\u2019s load-bearing structure. For example, the exterior walls were implemented without separate pillars. \u201cWe compared the pros and cons of numerous alternative structural solutions,\u201d Rossi says. Costs, functionality, buildability, carbon footprint and energy efficiency were the most important factors in terms of the final choice.<\/p>\n

The process of combining innovative wood structures and technology requires seamless cooperation. \u201cWood is a sensitive material with less load-bearing capacity than concrete or steel. This is why we took the utmost care in going over the lead-throughs and technical rooms with the structural engineers,\u201d Hakulinen says.<\/p>\n

Interaction within the same company was easy. \u201cWe could react to changes quickly and provide the client with solutions that worked from the perspectives of both structural and building services engineering,\u201d Hakulinen says. Information modelling was also used to fit the various technical categories together. \u201cBuilding information modelling is also an important tool for energy calculation and carbon footprint simulation.\u201d<\/p>\n

A long-lived wooden school is a carbon sink in itself, and Satavuo School is also a low-energy building. 40% of the annual power consumption is generated by means of solar panels, and the school is heated with its own pellet power plant. \u201cIn addition to this, energy circulation is supported with a needs-based ventilation system with heat recovery,\u201d Hakulinen says.<\/p>\n

On 1 February 2021, Satavuo School received the OKKA Foundation\u2019s sustainable development certificate.<\/p>\n
