8. Focus Create an environment that is inviting First space to be seen inside the existing building Be able to provide different appearance schemes Must be able to serve multiple purposes (main hallway during the day, social gathering space in the evening) Criteria Avoid reflected glare Specular floor surface Provide sufficient light to paintings along walls Divert attention to walls rather than specular floor Provide 10-20 fc on floor Provide > 15 fc on paintings Maintain a power density < 1.3W/ft^2 Lighting Design: LobbyDesign Focus and Criteria

9. Remove and relocate columns from center of lobby Implement 6” 32W wallwash/downlights along perimeter walls and 6” 52W downlights over stairwell Install 4’ 32W strip cove lights along new perimeter shelf of cove • Install dimming controls in ticket booth for perimeter wallwash/downlights and cove lights Lighting Design: LobbyDesign Solutions
