21st NCBC Conference

COURSE DESCRIPTION

This session goes in-depth on commissioning of facility lighting and lighting control systems. This presentation lays the foundation for commissioning lighting systems in the design phase. Part 2 of this presentation focuses on the construction phase.

This presentation describes impacts of lighting design review and commissioning. The presentation uses industry standards and two case studies to discuss early lighting design involvement, along with the CxA's role in design review according to current IES lighting Cx guidelines; energy implications of early lighting design decisions; a CxA’s OPR and BOD review methodology for lighting; and a CxA’s design review methodology for lighting.


At the end of this session, participants will be able to:

1. Learn how to identify basic lighting issues with other

professional disciplines involved the building design review

and submittal process

2. Participate with design team in development of integrated,

phased approaches and activities for daylighting and

lighting commissioning

3. Describe and recommend lighting system commissioning

and daylighting system commissioning methods, phases,

and testing opportunities to owners and design teams

4. Identify red flags in lighting system design and daylighting

system design

UNDERSTANDING LIGHTING FOR A CXA

• DG-29-11 documents all requirements

• Include big ideas with smart goals in the

OPR

• Who are the occupants

• Describe tasks

• Minimizing Lamp Types

• Desired Level of Control

• Integration Goals

• If no OPR, CxA needs to be aware

of pitfalls in subsequent reviews

• BOD informs the design as the

OPR informs the BOD

• Identifying lighting issues now

saves time and money later

• Review requirements include

making sure the BOD meets

the OPR

• BOD may not be achieved

early in the predesign process

• Occupancy sensors are in ASHRAE/IESNA 90.1

• Finding discrepancies & improper applications

• Ultrasonic or Dual Technology Sensors in spaces with barriers

• Coverage pattern matches application & area

• Make sure sensors are detailed in the Specification (26 27 26)



Sensors come in many different shapes and

sizes, each with specific performance

criteria and application

• Check that override

controls are located for easy

use by cleaning staff

• Avoid whole-floor overrides

• Ensure that specification

includes language

documenting accessibility to

controls & programming

vendors or electricians but represent a

barrier to building managers

• A couple of hours and a lighting model later, you can identify over-lit spaces

• LEDs increasingly appear in design documents and the CxA needs to know how to identify quality products

• Recommend LED fixtures for high or otherwise difficult to maintain areas

• Avoid TT5 (long CFL) lamps

• The luminous efficacy (lu/W) is low

• Maintenance is problematic



The widening application of LEDs may push TT5

lamps out of the marketplace
