Energy Code Update Key Points Adoption of the new Energy Code will be impacting projects and specifications in Montana. Newly adopted energy codes have slightly different requirements, so be aware! Northern Rockies Agency does it’s utmost to help keep our partners on top of code requirements and developments for their projects.

In December of 2004, Montana will begin the enforcement of the 2003 International Energy Conservation Code (2003 IECC). What is this going to mean to you?

Missoula will be enforcing the 2003 IECC as of Dec.3, 2004

Lighting Systems Scope Applies to the design of: –First installed lighting systems in conditioned or unconditioned spaces –Altered systems as part of alteration –Altered system that increases the lighting load if change of occupancy –Exterior lighting systems 2003 I.E.C.C.

Interior Lighting Requirements : Interior Lighting Power Requirements Partial Building Mandates : - Controls - Switching - Wiring Entire BuildingInterior

IECC 2003 Interior lighting controls At least 1 manual control for each area enclosed by walls, or ceiling height partitions Must be located in the space Remote location OK if –the switch identifies the lights being controlled and – indicates status Exceptions Areas that must be continuously lit Spaces part of means of egress (stairway, corridor, etc.)Interior

IECC 2003 Additional Controls Additional controls for each area required to have a manual control Additional controls include: –Light Reduction Controls, and –Automatic shut-off, and –Guestroom controls (when suits application) Exceptions –Areas with 1 luminaire –Areas controlled by occupancy sensors –Corridors, storerooms, restrooms, public lobbiesInterior

IECC 2003 Light Reduction Controls 50% load reduction via the following: – Controlling all lamps or luminaires (Dimming – Daylighting) – Dual switching of alternate rows, luminaires, or lamps – Switching independent lamps within a luminaire – Switching each luminaire or lamp Exceptions: Areas with 1 luminaire Areas controlled by occupancy sensors Spaces that use < 0.6 W/ sq. ft Corridors, storerooms, restrooms, public lobbies, guestroomsInterior

Bi-Level Switching Compliance Examples Example: Alternate Luminaires SSInterior

Exempted areaIECC 2003 Ltg for 24-hr operation √ Areas controlled by occupancy sensor √ Corridors, storerooms, public lobbies √ Areas with 1 luminaire √ Automatic Shut off Exceptions

Exterior Lighting Requirements: Mandatory Requirements: - Controls Exterior Lighting Requirements: - Energy Efficient Sources - Use Load Shedding Devices 2003 IECC

Automatically Turn Lights off During Daylight Hours – Photo Cell – Automatic Time Switches Seven Day/Seasonal Daylight Program 4 hour Minimum Backup – Exception Lights Intended for 24-hour Operation 2003 IECC Exterior

Demonstrating Compliance Section 104 Include the following information on the electrical plans –Switching / Dimming schemes –Make/model of exterior lighting controls –Make/model of interior programmable controls –Notes for tandem wiring –Make/model of the occupancy sensors –Sensor placement scheme
