The purpose is to capture the total load that a bldg’s AC equipment will need to meet. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I am NOT trying to simulate a specific building - just a generic “office”, or “school”, or “hospital”, etc. To that end I dashed off a model w/o entering a single user input – all SD Wizard defaults. Assumption being that the defaults are suitable for “typical buildings”. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>‘----> Is this a reasonable assumption (using all defaults to represent “typical” bldg)? <o:p></o:p></p><p class=MsoNormal>‘----> Or are there some inputs – like system parameters - that I must define in order for the model to produce ball-park accuracy?<o:p></o:p></p><p class=MsoNormal>‘----> Which variables should I pull from the Hourly Blocks to make an 8760 hour report showing total cooling load equipment would need to meet?<o:p></o:p></p><p class=MsoNormal>*----> I noticed my “Building Loads” cooling load data (2 variables: sensible, latent) are much greater than “Building HVAC” cooling load data (1 variable: “coils+losses+gains”). “Building Loads” shows 472 kBtuh at the peak while “Building HVAC” shows just 296 kBtuh at same time. What is going on here?<o:p></o:p></p><p class=MsoNormal>*----> Finally, where do I find the OA Ventilation latent load? <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>My larger objective is to develop profiles for a fair size list of building types with the most common equipment combinations (location: Texas). <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I believe the cooling load depends on the equipment type to a certain extent, since some loads are added by the system components, such as fan or pump energy. Therefore, in order to develop a cooling (and heating) profile for each building type/equipment type combination, I suspect I’ll need to ensure that the system (and/or plant) is defined appropriately. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>‘----> Is that the right way to think about it?<o:p></o:p></p><p class=MsoNormal>‘----> Which additional variables would I need to pull for the load profile for a bldg. w/ a chilled water system?<o:p></o:p></p><p class=MsoNormal>‘----> Any suggestions?<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>(As you may have guessed, I’m familiar with eQUEST but have only limited experience.)<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Thanks for any advice,<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Willis Nessle<o:p></o:p></p><p class=MsoNormal>Nexant, Inc.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
