Description

The The invention relates to a device for data acquisition of the same surrounding indoor climate as well as a method of proving the crossing of limits of the indoor environment.

By the legislation comes in the form of energy saving regulations Building physics to your limits. The building envelopes inevitably become ever denser. A natural one Exchange of moisture caused by moisture in the Construction of the masonry, in plastering of walls and Covering, when laying E-line coverings, as well as moisture through the use of the premises in the form of natural Persistence of moisture of the body, water vapor by cooking, bathing, showering, drying clothes inflated stocking of planters in closed rooms is not more given.

The The result is mold and the formation of microorganisms which lead to significant damage to health and that Failure of components such as windows, doors floors, Furniture, etc., which are at the same time damaged. In case of damage must clarified the question of guilt in judicial disputes whether built-in materials, improper planning or design the building physics blame or even the user behavior the wrong is.

As well it happens to landlords, which in the formation of mold and microorganisms in the proof that the tenant is not properly the premises ventilates, heats or even to a considerable extent laundry in the closed apartment dries.

Bauschadensprozesse, Rental deductions, rental processes, claims for damages are this triggers the usual reaction and employs ours Dishes in excess.
