Seven built-in parlours (A) and 6 stand-alone parlours (B) were included in the long-term follow-up. The air temperature in the exterior and in the interior of the parlour was measured throughout the year. The measured values were divided into three zones (1st zone: cold period, zone 2nd: transition period, 3rd zone: warm period). The differences in air temperatures in parlours A and B were not statistically significant in any zone. The construction disposition of the parlor did not affect the temperature conditions in the parlor interior. The air temperatures in the parlour were strongly dependent on the exterior air temperature (A: r = 0.9285; B: r = 0.9402).
