Method for converting CWEEDs weather files to EPW format for multiyear simulation of building thermal dynamics

This paper outlines a method in converting Historical CWEEDs (Canadian Weather Energy and Engineering Datasets) stored in WY3 format into individual weather files in EPW format so it could be used for Building Energy Simulation (BES). The method outlined is independent of the programming language used, however, a sample MATLAB script is presented to illustrate its feasibility. Highlights of the methodology are as follow:• Key feature in weather converters created under this methodology is the ability to divide multiyear weather data stored in WY3 format (with. wy3 extension) into individual years in EPW format (Standard mode)• And provide ability to extract weather data within a defined time range
