There are always exciting things going on in Milwaukee Public Library’s Downtown Central Library, 814 W. Wisconsin Ave. But, these days, there is also some excitement on the building’s roof, too.
When the library needed to replace its 25-year-old roof last year, instead of going for a conventional roof, a 30,000-square foot green roof was constructed and 132 solar electric panels were added to generate about 36,000 kilowatt hours of electricity per year. That’s enough to power four homes annually.
