Howard County General Hospital
Schematic Design Proposal
Casey Schardt
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.
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
General Considerations
• Cost/Efficiency
– It is important to minimize costs while maintaining quality of
all systems.
– This includes initial costs, maintenance costs, and operational
costs (power consumption)
• Age of Occupants
– Increased light levels to accommodate the elderly.
– Increased uniformity (older eyes are more sensitive to glare
sources.
• Atmosphere
– It is important to keep the hospital as uplifting as possible, to
ease the feelings of anxiety and depression that the patients
may be experiencing.
– An appearance of cleanliness should be conveyed.

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
Lobby/Reception Area
Design Criteria
• Reception Desk
– Ambient Illuminance: 30 fc
– Illuminance on Desk: 50 fc
– Low uniformity (4:1) on surfaces to minimize
veiling reflections both in paper tasks and VDTs
– Minimal direct glare
– Good color and modeling of faces
Lobby/Reception Area
Design Criteria
• Waiting/Vending Areas
– Local level of 30 fc available for reading
– Minimal glare to reduce veiling reflections in
reading material, such as the glossy pages of
magazines
• Corridor
– At least 5 fc for orientation
Reception Area
Fluorescent
Louvered Slots
(in bulkhead)
Semi-Indirect Pendant
Reception Area
• The semi-indirect pendant is to provide
the receptionists with an ambient light level,
while minimizing veiling reflections in their
VDTs
• The fluorescent slots are to provide the
necessary additional light on the desk
surface, while minimizing glare and veiling
reflections from the horizontal surface.

spotlights
Waiting Area
• The semi-indirect pendants are to provide
ambient light levels in the waiting area. They
also provide a bright ceiling to convey a brighter
appearance to the room.
• Table Lamps are provided to allow the user to
increase the light level for reading. They also
convey a more comfortable residential mood.
• Paintings with spot lights are added to
contribute some visual interest to the space for
patients to take their mind off waiting.
Lobby/Reception Area
• Corridor and Vending Area
– These spaces will also have the same pendants
to match the waiting area and reception desk.
• Color
– The standard CCT for the hospital is 4100 K,
however this area is to have a lower CCT of
3500 to give the space a less intimidating, more
residential atmosphere.

Design Criteria
• Nurse’s Desks
– Ambient Illuminance: 30 fc
– Illuminance on Desk: 50 fc
– Low uniformity (4:1) on surfaces to minimize

Design Criteria
• Charting
– Ambient Illuminance: 30 fc
– Low uniformity (4:1) on surfaces to minimize
veiling reflections both in paper tasks and VDTs
– Minimal direct glare
• Corridor
– At least 5 fc for orientation

Linear SemiIndirect Pendants
Nurse Station
• The linear semi-indirect pendants are to
provide the nurses with an ambient light
level, while minimizing veiling reflections
in their VDTs
• The fluorescent slots are to provide the
necessary additional light on the desk
surface, while minimizing glare and veiling
reflections from the horizontal surface.
Nurse Station
• Corridor
– 2x4 lensed troffers will be used in the
surrounding corridor spaces.
• Color
– The hospital’s standard CCT of 4100 K will be
used for the nurse station and surrounding
corridors.

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
Conference Room
Wall

Semi-Indirect
Pendants
Wallwash Downlights
Conference Room
• The linear semi-indirect pendants are to
provide light to the table and give the
ceiling a high uniform illuminance
• The wallwash downlights, along with the
pendants provide indirect light delivering
light to the background, and contributing to
a high uniform vertical illuminance.
• The wall slot is simply to provide light to
the white board when necessary
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
Overall Lighting Design
• There are many ways that the efficiency of
the lighting system can be improved.
• For example, downlights with 2 horizontal
compact fluorescent lamps are used
extensively throughout the building. These
fixtures have an efficiency of 39%.
• 1x4 linear fluorescent fixtures, which are
much less efficient than 2x4 fixtures are
also used in many locations
• The benefits of using more efficient fixtures
will be examined.
Overall Lighting Design
• T-5 lamps can be used in many types of
fixtures also to increase their performance.
• More dimming controls will be added in
many spaces to allow the users to reduce the
amount of light they use, if desired,
especially in those spaces with available
daylight.
• Automatic shutoff devices, such as
occupancy sensors will be added in spaces
where energy can be saved when no one is
in the room.
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).
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.
Electrical Design
• New load calculations will be done to
account for reduced lighting loads due to
installing more efficient systems.
