By 1978, it had become apparent to library leaders that the Carnegie Library was simply too small to house the rapidly growing library collection. In 1979 a firm of architects were chosen and construction began on a new library for the Brownsburg community. The new library would be located on Jefferson Street, just two blocks away from the Carnegie Library. The Jefferson St. library was intended to reflect the latest in libary design. Energy effiency was the main design element, and the library was the first in the state of Indiana to be solar heated and lighted4. Additional design features also promoted energy effiency. The entries were designed to face away from winter winds, and the windows were designed to be opened during the summer to keep the cost of air conditioning down4. The library would also feature a separate children's area, which had become a popular library feature in the mid-twentieth century4.  The $1.8 million building was completed in August of 19814. The library had 25,000 square feet of space and even housed six computers, a new state of the art technology2.
