This helps with a variety of decisions, from determining the cost to condition a space, or the viability of foregoing mechanical systems altogether.
ECOTECT WEATHER DATA FILE PLUS
The TMY Plus utility creates confidence intervals for the temperatures levels represented in the TMY file, allowing the user to understand to what degree the weather file can be expected to accurately predict real weather patterns. The availability of TMY data makes it highly universal however, the results represent typical extremes and cumulatively contribute to seasonal and annual averages, creating uncertainty about how realistic our energy model outputs may be.
ECOTECT WEATHER DATA FILE SOFTWARE
This includes industry standard software such as eQuest, Energy Plus, and Ecotect, as well as proprietary software developed in-house. We rely on government-provided TMY (typical meteorological year) weather files to provide data for the weather parameter found in building performance simulation software. The months are chosen by statistically comparing individual monthly means with long-term monthly means for daily total global radiation, mean, minimum and maximum dry bulb temperature, mean, minimum and maximum dew point temperature, and mean and maximum wind speed.Can weather files generated for energy modeling reflect worst and best case annual scenarios? The use of SUNY data allows the use of many stations, especially autostations, that would otherwise not be suitable for use in CWEEDS files owing to lack of cloud observations for estimating solar irradiance by the MAC3 model.Ĭanadian Weather Year for Energy Calculation (CWEC): FTP downloadĥ64 datasets created by joining twelve Typical Meteorological Months selected from a database of up to 30 years of CWEEDS hourly data. Previously, the CWEEDS solar irradiance fields were primarily based on the MAC3 model estimates using sky condition and cloud layer type and cloud amount observations from 24/7 staffed weather stations. SUNY data sets are available at about 10 km grid spacing for 1998-2014 for all of Canada south of 58° N. For locations where solar irradiance observations are not available (the vast majority), solar values are now primarily based on satellite-derived solar estimates using methods developed at SUNY (State University of New York) and provided to Natural Resources Canada and Environment and Climate Change Canada by Clean Power Research. This 2016 version of the CWEEDS files has several different characteristics compared to the previous major release of CWEEDS files from Environment Canada in 2005. The dataset released in 2016 includes 492 Canadian locations with at least 10 years of data for the period between 19. Previously, the 23 northern locations incorporated solar radiation estimated by the MAC3 cloud-layer model described in the 2016 release notes below. All 95 locations north of 58° N in this release now incorporate solar data from this new northern gridded solar data set. National Aeronautical and Space Administration). There are 72 new locations at northern sites incorporating solar data in a gridded data set derived from polar-orbiting meteorological satellites, developed in a cooperative project involving Natural Resources Canada, SUNY (the State University of New York), and NASA (the U.S. The period has been extended three years to 2017. There are now files for 564 Canadian locations compared to 492 in the 2016 release. This dataset has been updated with the most recent changes made in July 2020.

Updates of IDF files are provided approximately every two years depending on the availability of data.Ĭanadian Weather Energy and Engineering Datasets (CWEEDS): FTP download In addition, historical versions of IDF files are also available for download. Current IDF files can be accessed through our station finder application or downloaded for each province and territory across Canada. Intensity-Duration-Frequency (IDF) Files: Includes the latest version of short-duration rainfall Intensity-Duration-Frequency (IDF) statistics in the form of tables and graphs with accompanying documentation for various locations across Canada.
The Historical Data Daily and Monthly report summaries are updated by adding the extremes for Total Rain, Total Snow, and Total Precip in the daily and monthly reports where the values are available. The Canadian Historical Weather Radar has been updated so that the radar images delay reduced to 20 minutes.
