Our vision of energy efficiency
1. Reduce the energy demand
• Bioclimatic design
• High performance insulation, airtight building envelop
2. Use high performance equipments
• for heating, cooling lighting, ventilation and hot water,
• locally produced renewable energy
3. Optimize and ensure operational performance
• Proper maintenance over time
• Efficient monitoring, measurement and management
By doing so, it is possible to cost-efficiently reduce by 80%
the energy consumption of the building stock.

The Context
Looking at savings potential of buildings
• Buildings (approx 210 Million) account for :
– 40% of Europe’s energy consumption
– 36% of Europe’s CO2 emissions
• Building’s life span > 50 years
• Buildings undergo major renovations every 30 years
• CO2 and RES on track for 2020, not EE
• EPBD recast only addresses new built & major
refurbishments
• Biggest savings potential lies in existing building stock
Biggest savings deemed to remain untapped
if no action is taken

Barrier : Awareness
Domestic use of energy

Barrier : lack of clear targets
• No clear incentive for strong actions
• Potential of savings remains unquantified
• Low hanging fruits attitude prevails
• Lock-in effect far below full potential
• No incentive to act at national level
– build capacity,
– develop training & technical know-how
– develop support programmes
No vision on how to meet 2050 targets
RE.gif
Barriers : Economics
Do we ask the right question (s) ?
• Refurbishment investment to increase by
What does
200€ billion (will)decade
over next it cost (Source:
to SAVE EC)
one unit of energy ?
• Accessibility of available money
• Payback time and
• Lack of strong fiscal incentives
What does (will) it cost to BUY
• Landlord / tenant dilemna
one unit of energy?
RE.gifOpportunity:
Positive economic impact
Renovating buildings so that they consume 80% less energy :
• Save 32% of EU’s primary energy consumption
= Energy produced by coal and nuclear
= 4 billions barels of foreign petrol oil
• Create 2 millions jobs in EU
• Co-benefits : Higher quality energy services :
– Better thermal comfort
– Health : Better indoor air quality
– Positive valuation of buildings
• Co-benefits : Risk reduction
– Less risk of damaging building construction
– Less poverty risk in case of steeply increasing energy prices
RE.gifOpportunity :
Meet Climate Targets
Meeting EE 20%
targets would
enable a de facto
reduction of 25%
GHG by 2020
RE.gifOpportunity
Respond to EU citizen’s expectation
• 80% Europeans support
mandatory energy savings
targets
– Priority to household savings
– Smart metering and transparency
– Tax breaks for EE investments
• 81% citizens in favour of
measures to reduce energy
precariousness
• EE : Stakeholders expect strong

1990 2010 2020 2050What to do ?
Encourage Deep Renovation
• Achieve reduction in energy consumption of 80%
• Incorporate available energy saving technologies
• Start with building envelope (measures providing most
savings, then RE & equipments
• 3% EU buildings renovated each year for the next 40
years = meeting 2020 & 2050 energy & GHG targets
• EEP :
– Public sector (12%) to lead by example, private to
follow
– Ambition needed to avoid lock in effect
RE.gifWhat to do ?
National roadmaps for wide-scale renovation
Member States should be encouraged to :
a) Complete the deep renovation of their entire
building stock by 2050
b) Define ambitious intermediate objectives for
2020 and 2040
c) Develop a roadmap to achieve these objectives
according to local, regional and national needs
d) Set targets at building stock level and per
building type
RE.gifThe ISOVER Energy Efficiency Awards
• Since 2007, every 2 years
• Target: established
professionals www.isover-eea.com
• Objectives: to reward
Europe’s most successful
building renovation and
construction projects; to
emphasize the creative
and innovative ways by
which energy efficiency
can be achieved
RE.gifTo conclude
• Key role of buildings
• Look at the EE challenge from the right side, namely,
how to reduce demand first
• Build scenarios towards 2050, per sector
• Buildings : Deep renovation will be key
• Renovating 3% of building stock per year = meeting
energy & GHG target by 2050
• Increase awareness : Renovate Europe Campaign
