*3.5. Greek-Catholic Church*

The last location we have consiidered in this article is the Greek-Catholic Church of the Nativity of the Virgin Mary in Moyzesova Street. We also focused on the south-facing facade of the building. At 8:50 a.m., we measured 348 W/m2; v.sun (Figure 10) calculated a value slightly lower (237 W/m2) (Table 5). With the r.sun model, we again recorded a significantly higher value, due to the aforementioned facade representation issues.

At 11:44 a.m., the pyranometer recorded value of 534 W/m2. The r.sun and v.sun models also recorded similar values, which were increased compared to the morning measurement. The value recorded at 3:25 p.m. by the pyranometer (313 W/m2) is approximated by the v.sun model with a value of 357 W/m<sup>2</sup> and 202 W/m<sup>2</sup> by the r.sun model. This lower value by r.sun is clearly also affected by a geometric distortion of the DSM.
