The recent amendment of the building code („EnEV 2014“) has strengthened the requirements for new buildings from 2016, but
hardly any changes for the building stock.
However, the KfW Renovation Programme already today gives incentives for deep renovations.

The indivual building roadmap
Develops a long-term strategy for the
individual building,
Incentivises a renovation as deep as possible, Checks the compatibility of stepwise
renovation measures with the long-term target,
Considers the starting point of the building
and the user including low-threshold
renovation measures (context sensitivity),
Develops an optimal sequence and packaging
of measures and points to things to consider in the case of staged renovations.

Page 2: Current state: Efficiency, rising energy costs (etc.)
First step: develop the i-renovation roadmap as a
consultancy tool
The software program contains a database of many pre-written text items and checklists.
The „roadmap page“
The individual renovation measures must fulfilambitious technical
requirements. If these are not possible to fulfill, the consultant must explain the deviations.

State-funded energy audit product for private households
Similar tools are being developed for non-residential buildings and
building portfolios.
Integration into the renewable heating law
Baden-Württemberg has (as the only German State) a RES-heat
use obligation for existing buildings.
When biomethane or biofuels are used to fulfil the heat
obligation, a renovation roadmap must be provided to comply with the law
A small part of the use obligation can be covered with the
renovation roadmap. (5 %-points)

Baden-Württemberg renewable heating policy

Developing the subsidy scheme into the direction of a
longterm bonus-malus system
Energy tax/fee to fund the extension of the subsidy scheme Support deep renovation even more (higher subsidy rate for
most ambitious levels), especially individual measures (the more measures and the more ambitious, the higher the support)
Differentiate additional funding according to the situation of
the building (income level of tenants, etc.)
Include a reward for „target compatible buildings“ in
the property tax, the tax on purchase of real estate and
the death tax
Further possible approaches
