My building does not appear to be affected by its surroundings, despite having set high infiltration values (ranging between 0.5 and 0.005 floor rate per area). Additionally, the building has no insulation, as the walls are composed of 2 cm of lime mortar, 19 cm of ceramic brick, and 2 cm of gypsum mortar. No ventilation or HVAC system has been implemented, yet the building seems to remain perfectly insulated even under extreme weather conditions, such as 44ºC in summer in Barcelona. The indoor-temperature is never higher than 33º meanwhile the outdoor-temperature is minimum 34º.
I am struggling to understand this issue, and I have an upcoming deadline to provide accurate simulations. Does anyone have any insights?
