Castle Square facade

The Castle Square Apartments, a 1960s-era low-income housing development, will get a makeover on the outside and inside through the green building renovation. It will have a highly insulating exterior with a new look and an improved ventilation system designed to improve indoor air quality. Developers expect that it will get LEED certification from the U.S. Green Building Council. Construction of the project, which is funded by state and federal grants, is expected to cost about the same as a typical renovation and be completed next year.
