  21. HC FINAL REPORT Phil Mackey HOLY CROSS HOSPITAL – NORTH ADDITION Final Conclusions Lighting Depth – Registration Space – complimented architectural elements while keeping fixtures minimally obtrusive to the space, provided sufficient illuminance levels under ASHRAE 90.1 Power Density recommendations Main Lobby – utilized light as a means to call attention to particular functions and artistic features within the space, created a more inviting space by washing the back wall, provided sufficient illuminance levels for various tasks under ASHRAE 90.1 Power Density recommendations Electrical Depth – investigated cost impact of centralizing normal branch step-down transformers, provided alternative emergency back-up power generation system and assessed the feasibility of proposed implementation
