BUILDING EFFICIENCY – DRIVER FOR SUSTAINABLE DEVELOPMENT
SUSTAINABILITY
88% - 91%
WHAT IS THE GOAL?
STARTING POINT?
It is one of the most used words in European policytoday. We all agree it is important,but howwill we balance social,economic and environmentalobjectives when making decisions?

dependency
53%
We import
worth of energy each year of all the energy we use
or
Reduce the
demand for energy
by avoiding
heat losses and
implementing
energy-saving
measures.
Produce and use
fossil energy as
efficiently as
possible
Use sustainable
sources of energy
instead of finite
fossil fuels.

HOW CAN BUILDING RENOVATION CONTRIBUTE TO
SUSTAINABLE DEVELOPMENT?
REDUCING BILLS
If we want to save energy, buildings are a great place to start.
The most cost-effective savings potentials by2030,more than transport or industry, the other two big energyusers.
*% = cost-effective savings potential
REDUCING EMISSIONS
Buildings account for about
of the
EU’S TOTAL
CO2
EMISSIONS
36%
INSULATION IS ONE OF THE SIMPLEST AND MOST COST EFFECTIVE
WAYS TO IMPROVE THE ENERGY EFFICIENCY OF BUILDINGS,
WHETHER THEY ARE OLD OR NEW.

POLYURETHANE INSULATION IS THE RIGHT TOOL FOR THE JOB
EUROPE IS LEADING THE WAY
Energy used
to produce
the insulation
material
Energy saved by
using insulation
Additional insulation
will increase the
embodied energy of
buildings,but this is
more than largely offset
by use-phase savings.
At an equal thickness,PU insulation is the energy savings champion. This is especially important
in renovated buildings.PU insulation does more with less. Less material means less resources.
The EU cannot achieve its
climate goals unless the energy
consumption of buildings is cut by
80% by 2050.
A key element of this policy is that
all new buildings must have nearly
zero energy demand from 2021
onwards.
To reduce the energy demand of EU buildings by 80%
by 2050 an annual renovation rate of 3% is required.
Energy efficient buildings are a major
contributor to achieving the EU’s long-term
climate and energy goals.
Tackling the savings potential of existing
buildings is paramount.
PU is best placed to respond to these
challenges as it saves more energy for every
centimeter of insulation.
Member States must implement long-term strategies
for the renovation of the building stock.
EU legislation needs to create a
coherent framework for renovation.
The Energy Performance of
Buildings Directive introduced
several innovative tools:
- Energy performance certificates
- Pathway towards nZEBs
- Concept of cost-optimality
- Certain renovation requirements
- Inspection schemes
The Energy Efficiency Directive
added further important
requirements:
-National building renovation
roadmaps
-3% renovation rate for central
government buildings
-1.5% energy savings obligation
for energy suppliers
per year

At an equal thickness,PU insulation is the energy savings champion. This is especially important in renovated buildings.PU insulation does more with less. Less material means less resources. The EU cannot achieve its climate goals unless the energy consumption of buildings is cut by 80% by 2050. A key element of this policy is that all new buildings must have nearly zero energy demand from 2021 onwards. To reduce the energy demand of EU buildings by 80% by 2050 an annual renovation rate of 3% is required. Energy efficient buildings are a major contributor to achieving the EU’s long-term climate and energy goals. Tackling the savings potential of existing buildings is paramount. PU is best placed to respond to these challenges as it saves more energy for every centimeter of insulation. Member States must implement long-term strategies for the renovation of the building stock. EU legislation needs to create a coherent framework for renovation. The Energy Performance of Buildings Directive introduced several innovative tools: - Energy performance certificates - Pathway towards nZEBs - Concept of cost-optimality - Certain renovation requirements - Inspection schemes The Energy Efficiency Directive added further important requirements: -National building renovation roadmaps -3% renovation rate for central government buildings -1.5% energy savings obligation for energy suppliers per year IT SAVES ENERGY TOWARDS NZEBs 1 2 3 BUT MORE NEEDS TO BE DONE EPBD EED -1,5% IT SAVES SPACE & RESOURCES NZEB OBLIGATIONS 3% CONCLUSIONS
