**BS-8 teleconference minutes - #8**

6 November 2001

Participants: **Vlado Bazjanac** (LBNL, author of these minutes),
**Jean‑Pierre Bedrune** (Laurenti), **Philip Haves** (LBNL), **Rob
Hitchcock** (LBNL), **Veijo Lappalainen** (VTT), **Darko Sucic** (IKE),
**PC Thomas** (UNSW), **Mike Witte** (Gard Analytics), **Peng Xu**
(LBNL).

**Activity report.**

*Task 1 (Connectivity)* - Kent prepared a brief white paper. A large
issue, the harmonization of connectivity concepts from different
professions (building services, structural steel, etc.) still needs to
be addressed. The IAI Technical Advisory Group (TAG) will discuss this
in a teleconference in two days; the topic was not discussed in the last
TAG telecon. The EXPRESS modeling of the connectivity model will proceed
after that.

*Task 2 (Time series)* - EXPRESS modeling of the time series schema is
finished. A white paper will be distributed for review by the end of
this week.

*Task 3 (HVAC object/attribute/relationship sets)* - Definitions of 20
or so types of equipment are almost complete for first reviews. An
initial list was sent out yesterday to the BS-8 exploder and to members
of ASHRAE GPC-20. Additional lists will follow after more internal
review. Phil is seeking primary reviewers for individual equipment
definitions; please send nominations of candidates from outside the BS-8
group directly to Phil. The following primary reviewers were assigned as
follows: Darko - boiler, Veijo - recovery unit, Jason Glaser (and
Mike) - ducts, Jean-Pierre - space heater, PC - damper, Rob - chiller.
Preliminary reviews should be completed by Monday, November 19

*Task 4 (Electrical systems)* - Vlado was tied up by another project and
on travel for two weeks; the work on this will resume next week.

*Tasks 5 and 6 (Controls model + Relationship to BACnet)* - Phil sent an
invitation to participate to about 10 people with interest in modeling
of sequences of operation; some of those are in the BACnet community. He
already received a few replies and is planning an initial
mini-teleconference in the next couple of weeks.

*Task 7 (Integration of BS-7)* - Darko modeled property sets using the
XML model.

*Tasks 8, 9 and 10 (EXPRESS model, IFC model integration, and Early
implementation)* - Darko will meet with Granlund in Frankfurt on Friday
to discuss HVAC implementations in the BS Pro server. Gard Analytics is
interested in writing an interface for E+ that will allow equipment
manufacturers to import user input files and run options with E+. Jason,
Rob, Phil, Vlado and other interested parties will schedule a
mini-teleconference on the subject.

*Tasks 11 and 12 (Project support + Coordination with the overall
CEC/PIER project)* - Both supporting agencies (DOE and CEC) are
continuously informed about the work.

Tasks 13 (The Project Advisory Group) - No news were reported regarding
the Project Advisory Group.

**Rescheduling of the face-to-face meeting.** Because of a major
scheduling conflict for Vlado the face-to-face BS-8 meeting cannot take
place November 29-30. Instead of reviewing spreadsheets then, we will
first assess the quality of spreadsheets and review them electronically.
Then we can involve more outside people (including GPC-20) in a review
of the reviews, perhaps at ASHRAE in Atlantic City on Saturday (January
12) and Monday mornings (the GPC-20 meeting is the morning or at noon
that Monday). This will be resolved and scheduled via e-mail.

**Action items**:

-   Phil will distribute spreadsheets of the remaining HVAC definitions
    for review.

The next general BS-8 teleconference will take place on Tuesday,
December 4. It will start at 17:00 GMT, which is 9:00 PDT, noon EDT,
18:00 in Germany and France, 19:00 in Finland and 2:00 (December 5) in
Australia.
