Nick,
Type!
55 would allow you to integrate only over a certain time period (your 8am to 4pm time frame) and reset daily. Alternatively, you can get a daily sum of a function that has a value of 1 when the sun is up and a value of 0 otherwise: sunUp = GT(Ih,0) (where Ih is an output of your weather processor). That will get you the number of daylight hours each day. You'll then need to print out your hourly temperatures and do the integration in Excel after the simulation.
Best,
David

Is it possible to create running averages based on certain criteria? For instance, could I calculate the average of the temperature each day only when radiation is present (during daytime hours) so that the average does not re!
flect the cold nights?
The cl
osest solution I have found to this is to use an 8 hour running average, so that you are getting 3 averages each day:
Midnight to 8am, 8am to 4pm, and 4pm to Midnight. And then using Excel to average only the 8am to 4pm data and erase everything else. The problem with this is the radiation is still present after 8am or before 4pm at certain locations and depending on the time of season.
Thanks,
Nick

You can also use the utility model that creates a running average - in your case a running 24 hour average. This will keep you from getting step changes at midnight.

Lana,
I think you can also use Type55, from utility library.
Best regards

Lana, you can use Type127 to calculate an running mean value. Best regards, Arno Dear all, is there a Type that can calculate the average ambient d!
ay temperature of each day in the year, and where can I find it? I would like to use that to control the inlet temperature of a concrete core activation system.
