 ==== Comfort ====
-Thermal comfort is a defining living quality. The cold air pockets, drafts, uneven temperatures, and heat losses can all influence the comfort. With PHPP circulation, these factors can be calculated and controlled, ensuring balanced air circulation and consistently meeting the comfort standards.

 ===== Ventilation =====
+Window ventilation ensures the sufficient fresh air replacement. However, if ventilation is insufficient, the air quality will be poor and there will be a risk of condensation occurring. If too much ventilation takes place, the air will become too dry and energy consumption will become excessively high.  Read more about [[https://passipedia.org/planning/building_services/ventilation/basics/types_of_ventilation#purge_ventilation_through_windows|Purge ventilation through windows]]
