Union Trust Building

          The old Union Trust Building in downtown Pittsburgh adds its strange beauty to the understory of the city skyline.  It's the one with the Flemish-style roof.  Constructed by Henry Clay Frick in the 1917, the old skyscraper--now hardly worthy of the word--is being refitted for LEED certification by the Green Building Alliance.  Occupancy rates are very high in the "first tier" office towers downtown.  But in these old buildings, the occupancy rates are relatively low due to a lack of amenities: outdated heating and cooling systems, no employee parking, not enough restrooms, not enough electrical outlets, etc.  It's good to see them renovating rather than tearing down and building something ugly and cheap.
