Database Overview
The database includes around 100,000 valid certificates.

• Urban Apartment
• Up to 3 floors building
• T3 tipology
• Over 110m2
• C class energy certification


Currently 40% of the certiﬁed buildings have at least B-
as its energy classiﬁcation

Data Analysis – Outcome
Experts recommendations focus on domestic hot water, insulation and solar systems


Applying all the energy efficiency measures will result in
85% of the buildings being classified with at least B-

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

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

Marketing Assessment
Buildings


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

Intent Action
75% of Portuguese consumers claim to worry “Have you bought an environmentally friendly product in
about climate change and 59% believe that their the last month”, only 17% of the Portuguese
energy usage causes climate change. consumers responded with a ‘Yes’,

Source: Attitudes towards Energy, Special EUROBAROMETER 295/Wave 68.2-TNS
Opinion & Social, (PORTUGAL-2008)

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...
Top-most
reasons for the
‘gap’:

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...
