        4.Approval of the minutes from the previous meeting.
        5.Discussion and approval of the agenda for this meeting.
        6.Liaison updates (NEMA, IESNA, DALI)

        Robert Hick reported on progress of NEMA 243 DALI protocol standard
        and harmonization with IEC 602386 DALI protocol standard. Hope was to
        have a final draft for IEC voting by summer.

        7.Status of SSPC-135-2004 Addendum i PPR2
        The draft of SSPC-135-2004 Addendum i PPR2 was submitted to SSPC 135.
        It contains 2 unresolved comments. [post meeting edit: the two
        comments were resolved in the SSPC 135 meeting on Monday. The
        document was voted out for publication public review on Monday.].

        8.LA-WG proposal discussion / resolution via consensus

        DMF-047-1 - Theatrical Lighting Object
        David Fisher presented DMF-047-1 and a discussion ensued.

        Several points were debated:

        Separate Color Object.
        Color control has long been a part of entertainment lighting. It also
        was noted that color control is starting to be used for architectural
        lighting fixtures for both colored accent lighting and changing color
        temperature of white light sources such as LED's. Should BACnet lean
        toward addressing the architectural uses over the entertainment uses?
        It was noted that the Life Safety and Security working group had a
        multimedia control object that included x, y, pan, tilt, and zoom
        control for use with a security camera. Should there be a separate
        Color object? Can both a Color Object and LO be used to control the
        same light source? Should color properties be added to Light Object?

        How to best define color?
        It was noted that there were several ways to define color.
        RGB values – used in computers and entertainment lighting.
        CIE xy coordinates – Precise color, used to define LED's
        Color Temperature Tc– Used to define white light
        It was suggested that RGB is best for entertainment lighting devices
        while XY and Tc may be the best way to describe architectural color.
        The devices accuracy in attaining the desired color may be a local

        Robert Hick suggested that the IEC has done some very good work on
        defining control of color changing light sources and planned to
        distribute some of the drafts to Lighting Applications working group

        David agreed to review the information and make revisions to DMF-047
        for the next meeting.

        Discuss Addendum H clause H.X "Using BACnet with DALI"
        Robert noted that he discussed this with IEC DALI committee and they
        agreed to provide input. Robert agreed to continue working towards
        providing a draft later in the year.

        Review of Lighting Output white paper
        David Fisher drafted a white paper discussing BACnet lighting
        applications. The draft was reviewed by several committee members.

        9.Discussion of Non-Agenda Items
        10.Schedule for future meetings.
        The group plans to meet at the next SSPC meeting in Germantown in
        April, 2008. The date and time of the meeting will be determined at a
        later date.

        Meeting minutes respectfully submitted by Robert Hick. Edits by Steve Karg.
