Utrecht University says:
The Merriweather and Open Sans are our standard fonts for all communication. Centres and institutes of the UU can also use the Zilla Slab as an alternative for the Merriweather. The Merriweather is a serif font, with a high x-height, a bit narrow lettershape, a pronounced serif and an open expression.
Utrecht University uses a complex typographic model with both Open Sans and Merriweather used variously in body text, headings and subheads. The logo is still based on Bembo Bold.
