The arrangement of the 1953 National Building Code brought all the weather data together in one part. "Part 2: Climate," contains twelve maps of Canada on each of which are shown the variations in one weather element. Each regulation in the Code which depends on the value of some weather element contains a reference to the map from which a value can be obtained for any location. The charts are as follows: 1. Winter Design Temperature, 2 1/2 % Basis. -- 2. Winter Design Temperature, 5% Basis. -- 3. Mean Annual Total Degree-days, 65 degree F Basis. -- 4. Mean January Daily Minimum Temperature. -- 5. Mean July Daily Maximum Temperature. -- 6. Fifteen-minute Rainfall Expected Once in Ten Years. -- 7. Mean Annual Total Precipitation. -- 8. Computed Maximum Snow Load on a Horizontal Surface. -- 9. Computed Maximum Gust Speed. -- 10. Direction Frequencies of Winter Winds. -- 11. Earthquake Probability. -- 12. Approximate Southern Limit of Permafrost. Peer reviewed: Yes NRC publication: Yes
