Market Drivers and ConstraintsMarket Drivers and Constraints


Economic/Financial Incentives for residential buildingsReducing the gap between the European and Portuguese practices in the field


• End-use consumers

• Companies

• Mixed

Subsidies act as policy instrument to help incentivize end consumers

• Direct subsidies to the

private sector• Tax incentives• Loans• Direct subsidy to the public

An isolated Financial incentives programme won’t generate the expected result

• Requirements generally include an energy saving estimation of the measure to be implemented by a third party.

• Generally, countries adopt a combination of financial incentives programmes.

• Financial support is not the only focus of Governmental incentives. Educational campaigns and research and development also represent a main focus of the funds available for EE.


Subsidies program should be segmented to address the EE measures of old buildings

1) Different levels of segmentation are applied among countries to concentrate their efforts in supporting specific building targets.

2) Different levels of supports are provided to different EE measures.

Besides products, additional items associated to EE are integral part of Tax incentives programmes in EU


Financial instruments targeting a combination of EE products have proved to be more effective

Less frequently applied EE instruments in Europe

1)Countries like France, Germany have created subsidized credit programs

2)Some financial products are also combined with other instruments

Marketing Assessment- for the Portuguese Residential Buildings


There is a gap between Intent and Action in Consumer Behaviour...

75% of Portuguese consumers claim to worry about climate change and 59% believe that their energy usage causes climate change.

Intent“Have you bought an environmentally friendly product in the last month”, only 17% of the Portuguese consumers responded with a ‘Yes’,

Action

Portuguese consumers are aware of the impact they can have on Energy Efficiency but have not really translated their deeds into actions

The ‘gap’ affects the buyer decision process, thus hindering adoption of EE measures...

Whilst there are positive market drivers that will help in the long term, current market constraints also need our focus in the short-term...

There is a need to segment the market, before marketing of EE measures, because there exists, a varying ‘referencing’ behaviour of customers...

Energy Efficiency Measures

- for the Portuguese Residential BuildingsAction points


Equipments

• Improve Solar thermal penetration

• Increase the number of high efficiency boilers

•Higher efficiency in climatization systems

Building Envelope

• Insulation

• Glazing

Proposal

• Improve energy efficiency in residentialSector;

• Average savings of €514 /household in the annual energy bill

• Payback : from 6 to11 years

Current project, shows that energy efficiency in buildings will require a stronger focus in some priority key areas

Level of Energy Efficiency Implementation

Level of Energy Efficiency


Road map to get a higher efficiency level in buildings

Incentives and grants •Reduce price gap betweenHigh and low efficient products

• Follow EU best practices

Value Chain

• Product availability in new trade channels, eg.: - DIY stores/Hipermarkets• New “added value” services

• Market research addresingconsumer benefits• Above the line communications
