ASHRAE Design Conditions posted on EnergyPlus helpdesk
Posted by Linda Lawrie on 27 November 2012 03:24 PM

EnergyPlus SizingPeriod:Designday object definitions have been posted on the EnergyPlus helpdesk.

The ASHRAE Handbook of Fundamentals specifies design conditions for 5500+ locations.  These zip files have "macro defined" sets for each in EnergyPlus V7.1 (and later) format. Included in the articles are the "keys" to finding the location in the larger .imf files.

Climatic Design Conditions are discussed in the ASHRAE Handbook of Fundamentals, Chapter 14, 2009 edition.

Annual Design Conditions are (represented by the attachments in EnergyPlus SizingPeriod:Designday form) also discussed in this chapter.

Monthly Design Conditions (represented by the attachments in EnergyPlus SizingPeriod:Designday form) and how they are to be used are also discussed in this chapter. Monthly design conditions for dry bulb temperature (with mean coincident wet bulb temperature) and wet bulb temperature (with mean coincident dry bulb temperature) for .4% and 2% are included.
