About the project

The 16,000 m2 Central Library Oodi embodies a new era of libraries in Finland. Besides functioning as a traditional library, the modern and vibrant space serves as a new cultural hub for the citizens of Helsinki. The building is an example of a concrete, steel, wood and glass construction, making it highly energy efficient with an energy consumption level almost equivalent to a Zero Energy Building (nZEB). 

Key challenges

Oodi Library is a benchmark for energy consumption in modern high-technology facilities and included an LCA target. One of the key challenges was, thus, to build the library using mainly local materials while keeping the local climate conditions in mind. 


Ramboll was responsible for structural design, project management and construction as well as HVAC& Life-cycle design, maintenance book coordination and cooling design. Only the glass structures and some of the wooden structures of the façade were imported while the main structures of the building were manufactured in Finland. The library has an estimated life span of 150 years.
