Comparative Assessment of Three BIPV Curtainwalls

1.3. Weather Data

The model developed was implemented as a TRNSYS [11] component. It was then simulated for one year using the typical meteorological year (TMY) weather data and the Perez sky model for diffuse radiation for the three following Canadian cities: Yellowknife, Montreal and Iqaluit. From the cities climate information presented in Table 1, it can be observed that Yellowknife and Iqaluit have similar solar radiation potential than Montreal for south-facing vertical installation even though their global annual daily horizontal radiation is much lower. This can be explained by the cities high northern latitude and thus, lower sun angle throughout the year.
