Rocky River Public Library completed a phased renovation and entry expansion of their 1928 vintage public library building. Tec completed the engineering support for a rather extensive remodeling of the lower level community rooms, main level entry, reading room, and upper level children’s department. A major improvement in the lighting quality for the Grand Reading Room was achieved by replacing the existing wall mounted indirect fixtures and inefficient recessed ceiling fixtures with high performance energy efficient ceramic metal halide luminares. The concept for the interior illumination was to provide a comfortable environment and minimize debilitating glare. Providing illumination on the walls enhances visual comfort and increases the apparent size of spaces.
