Re: [EnergyPlus_Support] breaking up heating vs cooling loads

["Drury Crawley" <drury.crawley@xxxxxxxxxx>]

You would first want to look at the balance point temperature--the
temperature when the building is neither heating or cooling.  (This
will likely give you a range of temperatures, say 60-75 in a house,
depending on other loads.)

That would give you a way to break the other data--if outside temp is
above the balance point temp, then it's cooling, otherwise, heating.

		 Subject: [EnergyPlus_Support] breaking up heating vs cooling loads

>From Energy Plus, I have a years worth of energy data for a house.; I am wondering how to break it up into what contributes to the overall heating load and what contributes to the overall cooling load.; So far, all the energy data during hours the HVAC system is heating goes to the heating load and likewise, all the energy data during hours the HVAC system is cooling goes to the cooling load.; Pretty straight forward.; Yet I am wondering how to break up those hours when the HVAC system is off.; Right now all I do is put this remaining data into heating load if the hourly outside drybulb temperature is less then my inside temperature set point (70 C) and the rest of these hours into my cooling load.; This is just a rough estimate.; I am wondering if there is a set benchmark or what most energy pluser's due for breaking up the cooling and heating loads.

Thanks
