This study aims to raise the employment rate for people with disabilities. It quantifies the monetary value of improvement effect, introduces universal design to existing buildings, and provides basic data for facility management planning. Sixteen buildings owned by Company A have been investigated to evaluate universal design by applying the Comprehensive Assessment Systems of Universal Design Achievements (CASUDA) method developed by Sawada et al. Based on the findings of universal design evaluation, improvement studies were conducted and quantified the improvement effect and the facility cost. The installation of an elevator is most highly recommended on the evaluation, followed by toilet improvements, elevator retrofitting, and renovation of the corridor and stairs. The monetary value of a skeleton retrofit has been compared and elevator was most highly valued, whereas if new elevator shaft was not installed, the value is equivalent to that of a toilet retrofit.
