<p class=MsoNormal style='margin-bottom:10.0pt'><span style='font-family:"Calibri","sans-serif"'>I
assume that the 15 ft perimeter zone depth used in energy analysis is so that
the interior heat gains do not cancel out the envelope heat losses in winter
(when it is say -40 outside). Design loads programs are not affected
since interior heat gains are not deducted from the heat losses. Office
Building Envelopes are being designed to have up to 90% glass. The glass
can be from the bottom of the floor slab to the underside of the next floor
slab. The ceiling depth next to the glass is zero and it slopes down to
about 3 feet 2 to 5 feet away from the glass. Day-lighting can now reach
25 ft away from the glass. Also, when you turn the day-lighting option
on, the lighting load goes down and the heating load goes up.</span><o:p></o:p></p>
<p class=MsoNormal style='margin-bottom:10.0pt'><span style='font-family:"Calibri","sans-serif"'>Can
energy analysis programs have perimeter zone depths of up to 25 ft or equal to
the depth of the actual perimeter space (rarely will it be less than 10 ft and
could go up to the core zone) for day-lighting and set another zone depth of 2
to 5 ft for heating? </span><o:p></o:p></p>

for SPACE-CONDITIONS, ZONE-CONTROL and SYSTEM-CONTROL. I have used this
in DOE2.1E to set up “Design Criteria” for different types of
Spaces (based on building room types), types of Zones (terminal boxes, etc) and
types of Systems (VAVS, PIU, WLHP – starting with that shown in the
DOE2.1E BDL Summary). Templates of this type of information can be
transferred from one project to another and edited for the project. It is
similar to the TRACE700 Project Library.</span><span style='color:#333333'>
DOE2.2 has SET-DEFAULT that allows master data for one room, zone and system

<p class=MsoNormal style='margin-bottom:10.0pt'><span style='color:#333333'>It
is possible that I do not understand the DOE2.2 and eQUEST programs well enough
and I have missed something. The 6 DOE2.2 Manuals could do with more
examples showing the BDL for modeling PV, GSHP, TES, Load Management,
etc. Case studies would show the full picture. </span><o:p></o:p></p>
