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 Waiting Area Reception Vending Vestibule Children’s Area Bulkhead over desk

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

7. Lobby/Reception Area Design 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 Semi-Indirect Pendant Fluorescent Louvered Slots (in bulkhead)

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 Veiling Reflections are harmlessly bounced upward Uniform background minimizes veiling reflections in VDT screens

11. Lobby/Reception Area Design 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 Indirect Pendants TV Table Lamps Paintings with spotlights

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 Charting Corridor Staff Corridor

16. Nurse Station Section

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

18. Nurse Station Design 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 Station Design 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 Linear Semi- Indirect Pendants Fluorescent Louvered Slots (in bulkhead) 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 TV PC Monitor

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

25. Conference Room Design 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.
