What analysis focuses on the safety and vibrancy of a building's ground floor?

• A. Indoor Lighting Analysis
• B. Wind Comfort Analysis
• C. Eyes on the Street analysis
• D. Public Transportation Accessibility Analysis

Answer: (C)

Natural surveillance and street vitality are at play here: the safety and liveliness of a building’s ground floor come from how visible and active the street-facing front is. Eyes on the Street analysis looks at how people can see and be seen from the sidewalk—through transparent storefronts, accessible entrances, outdoor seating, and other ground-floor uses that invite pedestrians and occupants to be present. When there's continuous activity and clear sightlines at the street level, informal supervision emerges, deterring unwanted behavior and creating a sense of safety and energy for the area. This idea, tied to the notion that well-used streets with active frontages foster safer, more inviting neighborhoods, centers the impact of ground-floor design on everyday life. In contrast, Indoor Lighting Analysis focuses on interior illumination, Wind Comfort Analysis addresses outdoor wind and comfort, and Public Transportation Accessibility Analysis looks at how easily people can reach transit—factors that matter but don’t directly capture the downtown vibrancy and safety created by visible, active ground-floor frontage.
