4 National Renovation Strategy from 30 April 2014 Descriptive report of current situation The available instruments alone will not be sufficient to reach the ambitious goals. (p. 26) However, report contains only general ideas on future instrumental developments. 4

5 Today s instruments in the building sector (Selection) Energy efficiency Building code QP, HT, component requirements Renewable Energy RE heating law (new) Heat Law BW (building stcok) Small boiler ordinance KfW Programmes (1.8 bill ) (New construction and renovation) Energy taxes Market incentive programme (400 Mio. for RES heat) Energy audit programmes BAFA-Vor-Ort, VZ NRW, ESC etc. Energy performance certificates 5

6 Current situation Efficiency level Subsidy 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. EH 55 Only 3 % of the supported buildings have the level we need for the building stock in But: many owners use support for individual measures. EH 70 EH 85 6 EH 100 EH 115

8 Philosophy of the indivual renovation roadmap 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. 8

10 First step: develop the i-renovation roadmap as a consultancy tool Sanierungsfahrplan Baden-Württemberg Page 1: Why renovation? Co-benefits, etc. Page 2: Current state: Efficiency, rising energy costs (etc.) The software program contains a database of many pre-written text items and checklists. 10

11 The roadmap page The individual renovation measures must fulfil ambitious technical requirements. If these are not possible to fulfill, the consultant must explain the deviations. 11

12 Further pages with very detailed information What if e. g. what to consider if you insulate the roof first and then the wall Small measures Co-benefits First steps 12

13 Integration of the i-renovation roadmap into the Baden-Württemberg renewable heating policy 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.

15 Further possible approaches to link instruments to the i-renovation roadmap: IFEU ideas 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 15

16 The renovation puzzle Inform owners Target-oriented advice Create occasions for audits Campaigns Motivate owners One stop shop Further financial incentives Create visions for tomorrow Convoi retrofits Incentivise deep renovations, avoid lock-ins Building renovation roadmap More differentiated support. Overcome specific barriers Elderly people Owners assoc. Simplify instruments EnEV and EEWärmeG ISO standards Enforcement Activate professionals Incentives for architects and craftsmen Qualification One stop shop, craftsmen groups etc. Focus on cartiers and social housing Quartierskonzepte Heat plans Overcome financial barriers Support schemes New financing mechanisms Strengthen techn. options RES heat instruments District heating Innovative, cheap insulation 16
