Keelia, I am not sure which CWEC files you are referring to, but you can download the original CWEC (period 1960-1989) and the updated ones (CWEC16, data up to 2014) in the EPW format from the web. I think that would be the easiest solution to your problem. CWEC from US DOE : https://energyplus.net/weather-region/north_and_central_america_wmo_region_4/CAN CWEC16 from climate.onebuilding.org http://climate.onebuilding.org/WMO_Region_4_North_and_Central_America/CAN_Canada/index.html Michaël Kummert, Polytechnique Montréal From: TRNSYS-users <trnsys-users-bounces@lists.onebuilding.org> On Behalf Of Keelia LaFreniere via TRNSYS-users Hello everyone, I am new to TRNSYS 18 and I'm trying to get a Type 15 to read in a CWEC weather file (extension .WY3). I try to change the input file parameter to 5 in order to read the proper file format, but even going into the proforma and changing this value does not make any difference. I save the type after I've changed the parameter file, then run the program, but I always get the error that TRNSYS can't read the input file. I can't find the weather data for this specific region in any other format. Does anyone have any suggestions? Cheers, Keelia |
