On my instigation this building was renamed "Buys Ballot Laboratorium" after C.H.D. Buys Ballot, a physicist who in 1863 had started the Utrecht astronomical observatory together with the Dutch institute for meteorology at Zonnenburg. Actually, I proposed to call it "building" rather than "laboratory" since there was not much experimental physics anymore at that time already; most rooms held just desks with X-terminals or then new personal computers (especially Atari-STs). The director of the "Subfaculteit Natuur- en Sterrenkunde" accepted the renaming but stuck to "laboratory" although his own group in flame spectroscopy was also gone (the astronomers taking its floor).
Eventually, in 2011, the building was finally renamed to "Buys Ballot building" taking off the "Laboratory", but already in 2000 I had suggested a much more appropriate name. Presently there is no astronomy and almost no physics anymore in this building. Only the Institute for Marine and Atmospheric Research still warrants naming the building after Buys Ballot. It remains a monstrosity despite endless renovations.
