Howard County General Hospital

1. Howard County General Hospital Schematic Design Proposal Casey Schardt

2. Project Information • Location: Columbia, Maryland • Size: 81,000 square foot addition , and 44,000 square foot renovation to an existing 230,000 square foot facility • Cost: $20 Million Construction Cost • Constructed between September 2000 and July 2003. • New Emergency Dept., Birthing Dept., Neonatal ICU, Pediatric Nursing Unit, and expanded Imaging Dept.

3. Redesigned Spaces • Lobby/Reception Area: Includes reception desk, waiting room, vending area, and connecting corridors • Nurse Station: Features 2 desk areas open to the surrounding corridor, and an enclosed charting area • Conference Room: To be designed to accommodate meetings, audiovisual presentations, and video conferencing

4. General Considerations • Cost/Efficiency • Minimize costs while maintaining quality • Includes initial costs, maintenance costs, and operational costs (power consumption) • Age of Occupants • Increased light levels to accommodate the elderly. • Increased uniformity (minimal glare) • Atmosphere • Uplifting Ambiance • An appearance of Cleanliness

5. Lobby/Reception Area Children’s Area Vestibule Waiting Area Bulkhead over desk Reception Vending

6. Lobby/Reception AreaVisual Tasks • Reception Desk • Reading, Paper tasks • Interaction with patients • VDT use • Waiting Area and Vending Area • Light Reading • Relaxing • Corridor • Orientation

7. Lobby/Reception AreaDesign Criteria • Reception Desk • Ambient Illuminance: 30 fc • Illuminance on Desk: 50 fc • High uniformity (less than 4:1 luminance ratio) • Minimal direct glare • Good color and modeling of faces

8. Reception Area Fluorescent Louvered Slots (in bulkhead) Semi-Indirect Pendant

9. Reception Area • Pendant provides an ambient light level, while minimizing veiling reflections • Fluorescent slots provide additional light on the desk, while minimizing glare and veiling reflections

10. Reception Area Uniform background minimizes veiling reflections in VDT screens Veiling Reflections are harmlessly bounced upward

11. Lobby/Reception AreaDesign Criteria • Waiting/Vending Areas • Local level of 30 fc available for reading • Minimal glare to reduce veiling reflections (such as in magazines) • Corridor • 20 fc for orientation

12. Waiting Area Table Lamps TV Paintings with spotlights Indirect Pendants TV

13. Waiting Area • Pendants provide ambient light levels and light to ceiling to convey a brighter appearance to the room. • Table Lamps allow the user to increase the light level for reading. They also convey a more comfortable residential mood. • Paintings with spot lights contribute visual interest

14. Lobby/Reception Area • Corridor and Vending Area • These spaces will compact fluorescent downlights with cross-baffles • Color • Lower CCT of 3500 (more residential atmosphere)

15. Nurse Station Corridor Charting Nurse Station Nurse Station Staff Corridor

16. Nurse StationSection

17. Nurse StationVisual Tasks • Nurse’s Desk • Reading, Paper tasks • Interaction with patients • VDT use • Charting • Heavy VDT use • Also reading (paper tasks) • Corridor • Orientation

18. Nurse StationDesign Criteria • Nurses’ Desks • Ambient Illuminance: 30 fc • Illuminance on Desk: 50 fc • High uniformity (less than 4:1 luminance ratio) • Minimal direct glare • Good color and modeling of faces

19. Nurse StationDesign Criteria • Charting • Ambient Illuminance: 30 fc • High uniformity (less than 4:1 luminance ratio) • Minimal direct glare • Corridor • 20 fc for orientation

20. Nurse Station Fluorescent Louvered Slots (in bulkhead) Linear Semi-Indirect Pendants Lensed Troffer

21. Nurse Station • Pendants provide the ambient light level, while minimizing veiling reflections • Fluorescent slots provide additional light on desk surface, while minimizing glare and veiling reflections

22. Nurse Station • Corridor • Wall wash fixtures • Color • The hospital’s standard CCT of 4100 K for both nurse station and surrounding corridors

23. Conference Room Projection Screen Marker Board PC Monitor TV

24. Conference RoomVisual Tasks • Meeting • Reading, Paper tasks • Personal Interaction • Presentations • Projection Screen • Marker Board • Television and PC Monitors • Videoconferencing • Viewing Monitor • Camera Considerations

25. Conference RoomDesign Criteria • Horizontal Illuminance of 50 fc on table • Vertical Illuminance of 30 fc on faces • Vertical Illuminance of 30 fc on white board • Good uniformity on faces for videoconferencing • Minimal veiling reflections on VDTs and paper tasks • Good color and modeling of faces

26. Conference Room Semi-Indirect Pendants Wall Slot Wallwash Downlights

27. Conference Room • Pendants provide light to ceiling • wallwash downlights, contribute to vertical illuminance • wall slot simply provides light to the white board when necessary

28. Conference Room • The table surface is to have a high reflectance which will help to reflect some light to the underside of people’s faces, increasing uniformity • The wallwash downlights and the direct light from the pendants deliver a direct component for better facial modeling. • Dimming controls will be provided to achieve various scenes for each of the different uses of the space • Lower CCT of 3500K

29. Electrical Design • The emergency power loads will be calculated. • A new emergency generator will be sized for the addition (the facility’s existing generator was accurate, but I’ll design one assuming it wasn’t).

30. Electrical Design • An uninterruptible power source will be designed to serve the radiology equipment (currently when the generator starts up, the small power fluctuation affects this sensitive equipment.) • Panels located in the interstitial spaces will be eliminated and served from panels in other locations.
