IBO Ltd. provides services and technical consultancy that accelerate the development of ecological architecture based on the research from the IBO association.  Ecological building is the common purpose of both IBO Ltd. and the IBO association.

Building products, building services and equipment are examined to consider their whole-life cycle in a building and are appraised using building certifications.  Standardized assessments include the cradle-to-grave analysis of a product's environmental impact (lifecycle assessment), ecolabels, environmental product declarations (EPD) and building certification.

The IBO awards the IBO test mark and conducts tests for natureplus and the Austrian Ecolabel, primarily to inform end-consumers.
