The values for a typical wall of an old building, which is not even poorly insulated, are given in the first row. The occupants will spend about € 644 each year just to compensate for the heat losses through 100 m² of this wall. Applying insulation according to the Passive House standard, heat losses will decrease by a factor of 10; the annual costs for the energy loss through the external wall are reduced to less than 64 €/year.

In warmer climates or during summer months the interior surface temperature is also close to the indoor air temperature which means that it is lower than that of poorly insulated components which allow heat to be transported from the outside towards the inside. Highly insulated constructions have a **high temperature amplitude attenuation** reducing the temperature fluctuation of external building components, even with very small masses (e.g. double plaster board). | In warmer climates or during summer months the interior surface temperature is also close to the indoor air temperature which means that it is lower than that of poorly insulated components which allow heat to be transported from the outside towards the inside.
