The building that I was talking about has four 30 ton rooftop units that were never used for cooling from the get go. They only used the air rotation unit for heating in the winter. They reversed all the rooftop units fan flow to the warehouse/manufacturing areas and opened all the dock doors during the summer months. They essentially turned the rooftop units into a terribly inefficient exhaust fan to create a cool breeze for the workers in the summer time. A good portion of their electric consumption in the summer is due to the rooftop unit supply fans (now exhaust) running constantly and I believe off the top of my head that they are each 20 or 25hp motors. I was proposing to add sidewall prop fans on VFDs based on temperature and interlocked with louvers on the opposite side of the warehouse that would cut the fan power usage by about %70 and replacing that air rotation unit with several radiant tube heater vacuum systems. I originally modeled the building as is because I wasn’t going to try for the Section 179D, and was saving about 30% of their total utility costs. Could I add exhaust fans to the warehouse to recreate the rooftop units they converted even though it doesn’t show it on the prints If I were to model this as an ASHRAE 90.1 2001 baseline?<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><div><p class=MsoNormal><span style='color:#1F497D'>Thanks,<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>Tom Mickley<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>Mechanical Engineer CEM<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>The K Company<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>Cell 330-760-3994<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>Office 330-773-5125<o:p></o:p></span></p></div><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><div><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif";color:windowtext'>From:</span></b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif";color:windowtext'> Steve Jacobs [mailto:sjacobseng@gmail.com] <br><b>Sent:</b> Friday, April 25, 2014 11:38 AM<br><b>To:</b> Daniel Knapp<br><b>Cc:</b> Busby, Aaron; Tom Mickley; equest-users@lists.onebuilding.org<br><b>Subject:</b> Re: [Equest-users] Section 179D Question<o:p></o:p></span></p></div></div><p class=MsoNormal><o:p> </o:p></p><div><p class=MsoNormal>I've used this approach in the past. Appendix G requires the schedules to be the same, and where no cooling systems exist you need to model it the same as the proposed. The NREL guidelines say you can use the " [schedule of the] taxpayer’s building if they are known (see Section 3.6)." If a building has no cooling setpoint it is not unreasonable to interpret a no cooling setpoint as a high cooling setpoint. A large heated warehouse will have most its energy use in fans, lighting, and heat (depending on the heating setpoint). I don't think you would be gaming the system at all to have your model be consistent with the actual energy profile of the building. <br><br>- Steve<br><br>On 4/25/2014 8:45 AM, Daniel Knapp wrote:<o:p></o:p></p></div><blockquote style='margin-top:5.0pt;margin-bottom:5.0pt'><div><p class=MsoNormal>This requirement of adding cooling where it is not designed is an odd one to be sure.
