The Energy Renovation Programme 2020 “By 2020 there will be no more energy wasting dwellings in the Flemish Region” (2007)

Operational objectives: 1. Every dwelling has roof or attic insulation 2. All single glazing in dwellings is replaced by HE glazing 3. Every central heating boiler has an efficiency of at least 90 % 4. Every gas heater has an efficiency of at least 90 %



Energy behaviour of Flemish households Investments: Insulation

Financial incentives: subsidies


Household subsidies 2008 148.035 = 30.7 M€ (+ 80% to 2007) 64% of household subsidies = 95.000 to priority measures of the ER2020 programme z z

Easy to communicate Easy to understand

No measures subject to easy critics Support of all stakeholders

Measurable effects 7


Mix of measures…

Public support essential

How to implement? Step by step development of coherent approach supported by stakeholders with specific attention to structural measures Investigate which situations may lead to problems when imposing measures and find solutions

Result: 10 Recommendations 3 types of recommendations in 3 groups : z Technical procedures : 3 z Public support : 5 z Quality : 2

12


Recommendations – Technical procedures 1. Use the EPC-concept to check the conformity of the requirements to fulfill in 2020 This means a generalised application of the EPC-certificate

Æ proposed timing : political decision in

2010 – phased introduction until 2020

13


Recommendations – Technical procedures 2. The 3 mandatory measures are not always evident to apply and/or economically not optimal. Æ exchangeable with alternative measures with at least the same result (expressed as EPC number). But: roof insulation and glazing should meet minimal reqs (e.g. Umax)

Æ Proposed timing : political decision in 2010


Recommendations – Technical procedures 3. Present calculation tool for EPC to be optimised to perform recs 1 & 2 to make it an effective tool for evaluation for the proposed measures.


Recommendations – Public support 4. To create a sufficient basis in the private rental market, it is proposed to foster (non-)voluntary agreements between tenant and landlord. This would be eased by: * a simple tool to calculate a fair increase of rent for the energy saving investments and the mutual profit for both parties * providing appropriate model contracts * specific provisions for co-owned buildings *… Minimal quality reqs may be used For social housing: specific measures

Æ Proposed timing: results of additional studies available in 2011

16


Recommendations – Public support 5. To timely realise the voluntary measures before 2020, the government communicates a clear plan on the evolution of the incentive measures (type of measures, level of support, time table, …), an efficient communication strategy, sensibilising and follow-up are essential. Communication and fine tuning with federal measures is desirable.

Æ proposed timing: communication plan in 2010


Recommendations – Public support 6. Special attention for sensibilisation ans financial support of owners and renters with too poor incomes or without access to financing of the necessary measures.


Recommendations – Public support 7. For each of the mandatory measures (roof insulation, glazing, heating) clear preformance criteria and requirement levels are necessary. For the alternative measures (wall insulation, …) minimal requirements should be ensured.

Æ Proposed timing: concrete requirements in 2010


Recommendations – Public support 8. To maintain and enhance the necessary societal basis for the Energy Renovation Programme 2020, it is proposed to continue the consultation of the stakeholders at a rate of 2 meetings/year for follow-up, feed-back and correction.


Recommendations– Quality 9. The application of energy saving measures should be done in a qualitative way. Thereto a concept of quality assurance is proposed adapted to each type of measure and its risk of failure. Suggestions: * Training and education (esp. professional schooling) * minimal requirements on systems and on execution *…


Recommendations– Quality 10. The application of energy saving measures should lead to improvement of the indoor comfort and should not lead to physical problems. It is proposed to ask sufficient attention to flanking measures such as summer comfort, ventilation, etc.

2. Coherent long term plan for measures Æ See rec 5

3. Concrete requirement levels for 2020 Æ See rec 7

4. Quality assurance Æsee recs 9 & 10
