[Bldg-sim] energy plus/open studio hourly results (DView)

[Michael J Witte]

The structure of the various sql tables are fixed, but the contents of 
the sql time series output are completely user-specified. And generating 
output for the design day simulations is also optional. Each specified 
Output:Variable can be reported at one or more of the following 
frequencies: hvac timestep, zone timestep, hourly, daily, monthly, or 
annual.

So, to do as you suggest (always report drybulb and wetbulb to match the 
weather data), the user would create a snippet of input to add to every 
idf file specifying these output variables at the timestep frequency 
(due to sub-hourly interpolation it will match the hourly weather data 
once per hour).

Always interested in building bridges. Maybe we can pique your curiosity 
enough to consider adding another tool to your toolbox. :-)

Mike
p.s. See many of you soon in KC for ASHRAE and IBPSA-USA.
