    Sorry Nick, my bad regarding the tangent. What you've described in
    eQuest seems synonymous with the NoMass material in Energyplus.<br>
    <br>
    Perhaps I can bring it a little bit back on topic. Jeff mentions the
    use of Air walls to model existing buildings. However, if you know
    where all the partitions are in an <i>existing</i> building don't
    they introduce artificial boundaries?<br>

                                    we did on the Zachry building, which
                                    was the basis for the Predictor
                                    Shootout I
                                    and II, we looked at 1, 2, 5 and
                                    actual zoning on the building. What
                                    we saw was
                                    that, in general, the centroid of
                                    the "cloud" of data points remained
                                    about the same. However, the scatter
                                    in the cloud became more  pronounced
                                    at we added more zones.</span><span

                                    the zones in the floor are being

                                    zones per
                                    floor, depending on the functions of
                                    what's going on in each zone. Real
                                    walls
                                    or air walls between the zones

                                    way to get the light and receptacle
                                    loads on a real building is using
                                    "blink" tests, which can be done on
                                    a Saturday, with walkie talkies,
                                    and a data logger on the
                                    whole-building electric feed,
                                    possibly some sub feeds.
                                    I first heard of this test from Todd
                                    Taylor at PNNL. We've used it to
                                    help
                                    resolved motor loads, lighting
                                    loads, receptacles, etc. Seems to

                                    also several ways to get the plug
                                    loads, including: by proxy, by
                                    weather-day-type profiles, by daily
                                    readings, and a method that uses an
                                    energy
                                    balance. The proxy methods can use
                                    square proxies for for the occupancy
                                    based
                                    on OLF/ELF ratios, the
                                    weather-day-type method was
                                    something that I heard about
                                    from Don Hadley at PNNL, later
                                    adopted by Bou Saada on the
                                    Forrestal building
                                    and daycare center. The daily
                                    readings are just that, read the
                                    main meter by
                                    eye, daily, especially during
                                    weather independent times. The
                                    energy balance
