10.0pt;font-family:Arial;color:navy'>You would need to follow the ECB method in
ASHRAE 90.1 2001 or Appendix G of ASHRAE 90.1-2004, depending on which LEED
version you were using. In either case you would need to model the base case
building and the design case building with a cooling system defined by the ECB
or Appendix G for the base case, even if there isn’t one. This is
unfortunate since buildings using natural ventilation do not gain a benefit
from an energy perspective. I have heard that there is some lenience by the
energy reviewers for naturally ventilated buildings, but it may depend on which
person is doing the LEED energy review for the USGBC.<o:p></o:p></span></font></p>

building. The first floor is used as classrooms and retails. The 2nd and
3rd floors are used for residential units. Most of the systems on the
first floor are air-cooled condensing unit with electric heat-pump
heating, and the rest are exhaust fan systems. For the 2nd and 3rd
floors, the apartment units use unit heaters without any
cooling. Corridors on these floors are served by make-up air units with
gas-fired heating. There is not any warning or error when I simulate the model.

value. I have tried adjusting air flow, throttling range, etc w/o
achieving the desired results. I looked at SS-O report and the problem is
there are too many hours when the cooling isn't satisfied for 2nd and
3rd floor. In other words, for all zones on 2nd and 3rd floors there
are many hours when the units are over 80 - 85F or even
above 85F. I also tweaked the fans night control cycle, infiltration schedule,
set-point temperature, and zone entering max supple temp but the out of
throttling range is still exceptionally high. </span></font><o:p></o:p></p>

experience or solution? Has anyone done LEED model w/o
cooling? I would appreciate any response, idea or hints that
would help solve this problem. I have described the problem as clear
as I can but I am sure there are things that I may have left out,
please don't hesitate to ask me. Again, I am trying to get some ideas, hints or
