Harviainen, J. TuomasPikka, Harri2025-09-242025-09-242015https://repository.ifla.org/handle/20.500.14598/5493This paper discusses the systematic audio-spatial co-design processes implemented in four units of the Vantaa City Library in Finland. Using service design and co-design methods, staff and customers created together new library space designs which fit the needs of both current and potential future library patrons. Through the use of these techniques, customer experiences were significantly improved while the operational costs of each unit were reduced. The paper discusses these design processes through case examples and then makes suggestions for implementing such low cost, high impact changes also elsewhere.engAttribution 3.0 Unportedhttps://creativecommons.org/licenses/by/3.0/Articlehttp://conference.ifla.org/ifla81open accessAudio-spatialityCo-designLibrary SpacesPublic librariesService design
