Energy Code In Iowa
•
ASHRAE 90.1 -2010/2012 IECC applicable to Iowa
• 9.1 Scope:
• Shall apply to interior spaces of buildings
• Exterior
• Exceptions:
• Emergency lighting
• Dwelling units
• Life safety lighting such as exit signs
• 9.1.2 Lighting Alterations
• The alteration of lighting systems shall comply with LPD requirements
and automatic shutoff requirements in 9.4.1.1 (lighting controls!)

Energy Code In Iowa
•
Automatic Lighting Shutoff 9.4.1.1 requirements:
• A scheduled basis turns lighting off at specific programmed times
• Occupant sensor turns off within 30 minutes of vacancy
• Signal from a control system that indicates the area is unoccupied
•
Exceptions:
• Lighting required for 24 hour operation
• Spaces for patient care
• Spaces where automatic control would endanger the occupant or the
security of the building would be compromised .

Glossary: Technology
PIR
Passive Infrared, detects differences in moving air temperature
Ultrasonic
Emits a high frequency sound and interprets occupancy by
hearing changes in frequency changes. Highly sensitive to
small motions. May cause hearing aid issues.
Microphonic Listens for sounds related to human occupancy
Microwave
Continuous microwave radiation is emitted and interprets
occupancy by phase shifts in the reflected microwaves. Can
see through concrete very powerful/sensitive.
Dual Tech
Combines PIR with another tech inside the same device.
Typically lights are on when PIR triggers and stay on with the
other tech.

Glossary: Technology
Manual On:
Lights do not turn on automatically when entering a
room or space. aka: Vacancy Sensor
Auto On:
Lights turn on automatically. aka: Occupancy Sensor
Wireless:
Wireless connections from control to relay or switch
Wireless Mesh:
A wireless network that only has to communicate with
the nearest device not to home base.
BAS:
Building automation system
Zigbee
Communication language of many building automation systems
Large Zones:
Aisle or large area of facility controlled all at once
Fine Zones:
Individual fixture control
Cool:
Something you should do
Not Cool:
Something you should avoid
