The Ashby Free Public Library is a passive solar building, intended to serve as a model for the Massachusetts Board of Library Commissioners (MBLC). The project is an 8,000 SF addition to an existing masonry library. The two-story structure houses a children’s library on the lower level. The upper level contains a young adult’s area, main adult library, periodicals, and director’s offices. The resulting efficient plan separates children’s, and adults programming, while allowing integration on various levels. The South facing glazed portion acts as a passive solar element, allowing the warmth of winter sun to enter, with shading applied for the summer months. Complex site conditions were resolved with the design of a 30 foot long cantilever, allowing LEED certifiable covered parking.
