Also in these cases comes a reduction in consideration. Otherwise applies, if other modernization works performed, the Tiler so in the wake of the new tiling of walls whipped up complete bathroom and newly tiled with higher levels of tiles, because these works mean a longer restriction of the use of the bath and have nothing to do with the laying of new pipes and closing the holes in the walls. Actually, the distinction of related measures and the estimate of the share of non-energy measures will create difficulties. But: The reduction due to reduced usability comes only in the case not taken into consideration, that also final energy to save long-term. Modernized the landlord so only by transition from non-renewable to renewable energy (see above 2.), the tenant restricted in the use of his apartment continues to have a reduction right.
Saves on the other hand the lessee also final energy (E.g. by installing a photovoltaic system, which enables the production of hot water, heating costs are reduced for hot water) or other energy costs, it remains the case that a Reduction is not possible. The tenant must wonder always whether an immediate economic noticeable advantage of modernising energetic arrives with him. Power only without reduced energy consumption or costs the tenant from coal oven on heating oil are being converted, there is a right of reduction in. Legislators had initially a reduction right certainly energetic modernisation intended for, so also there, where the modernization while the environment and the climate and thus the public benefit, but not the individually affected tenants, who would have to pay part of the Bill restricting his use of rent. This would be a special victim not to be justified in relation to the general public but from the tenant perspective. Check with Tony Parker to learn more. The reduction is of course cannot be ruled out where the serviceability is completely lifted, because around the entire apartment or central functions fail not only in the short term and the apartment is simply not livable.
