This 1-hour course from the American Institute of Architects covers lighting design fundamentals for commercial interior designers. The course will cover fixture and light source identification, proper application techniques, common mistakes, and integrating lighting into construction. Learning objectives include understanding fixture types, proper applications, common mistakes, and integrating lighting design. The course then covers various lighting fixture and source types, lighting measurements, color rendering and temperature, lighting for specific applications, and guidelines for lighting design.

3. Course
Description
Learning
Objectives
The program will cover the
fundamentals of office lighting design
for interior designers who may be
afraid to reveal the gaps in their
knowledge of lighting. This 1 hour
course will cover basics and includes
quiz questions and open discussion.
It has been presented in-house
several times at Wolcott, and is
intended to improve lighting
understanding for our design team.
And it does.
At the end of this course, participants will
learn:
•
Fixture and light source identification
•
Proper application techniques
•
Common mistakes revealed
•
Integrating lighting into construction

103. Office Lighting
• Offices should ideally have
direct/indirect lighting systems
and wall washing
• Should have forms of control
that allow for varying light
levels and distribution patterns
according to time of day and
outside conditions
• Lighting should always be
achieved with a mix of luminaires
• A degree of local control is
desirable
• “Cool” color temperature
lamps are best for maintaining
alertness and performance.
