Why save energy?
 Security of energy supply
 Reduce global warming
 Green jobs
 Cleaner air, better health
 Cut energy costs

3
The last oil
 4 countries control most of
the world’s oil reserves
 3 countries control most of
the world’s gas reserves
 80% of the oil producing
nations are facing, or already
struggling with, declining
production
 Energy demand is growing,
reserves are declining

How long will our resources last?
Most of our energy consumption is based upon nonrenewable sources

Climate change – where should we
start?

Buildings are the biggest energy
consumer and CO2 polluter
33%
26%
41%
of all energy in EU is of all energy in EU is of all energy in EU is
used for transport
used by industry
used by buildings
2/3 of energy consumption in
buildings is used for heating,
cooling and ventilation.

Where do you use most energy?

Higher emissions & losses to come
 50% of world population live in
urban areas.
This will grow to 70% by 2030.
 Aircon will triple before 2030
(McKinsey/Vattenfall)
 CO2 emissions from buildings
will grow by 50+% by 2030.
Mainly in North America and
East Asia (IPCC).
 Affordable and Sustainable
housing should be a main priority

Buildings for the future?
A building can last 100 years
or more.
Short-sighted energy
inefficiency is costly.
10
10
More power plants or less energy waste?
It’s more costly to build new power plants
than to save energy
The cost of saving a unit of electricity is
2.6 euro cents compared to a price of
delivered electricity of 3.9 euro cents

Energy efficiency is the largest ‘energy
resource’ – and it is far from exploited!

How low can we go?
It is possible with existing and proven technology to have
buildings with a fraction of the present average consumption!

Jobs – Climate – Money
Modernise energy efficiently!
Every year energy waste worth € 270 billion and some
460 million tonnes of CO2 pollution could be saved cost
effectively. More than 500 000 jobs could be created in Europe
alone.

Job Growth from Energy Efficiency
Aggressive increases in US building energy
codes could result in
 Increase of nearly 1.1 million US jobs
 Increase in income of $28.5 billion US
 Decrease in energy use by 20.8 Quads

Energy refurbishment – the untapped potential
 Single-family house from 1927
 Renovated 2004
 Energy use for heating before:
5300 litre oil yearly
 Energy saving: 57%
 CO2-reduction: 8 tonnes/year
 Net profit $ 2,500 /year
20
20
Key recommendations
 Strengthen energy requirements
considerably
 Make the Passive House our
standard choice (mandatory in new
UK buildings from 2013)
 Always make building renovations
energy efficient
 Make public buildings energy efficient
role models
 Provide one-stop energy efficiency
packages for home-owners
 Provide up-front financing

The fight against
climate change
starts at home
Buildings account for some
40% of energy consumption
And a major share of
manmade CO2 emissions
Mostly for heating, cooling and ventilation
Most of this expensive energy is wasted

Energy saving = Environmental
profit
In its lifetime
(more than 50 years)
Rockwool insulation
can save more than
100 times the energy
used for its production.
Positive environmental
balance after a few
weeks.

Positive environmental balance (1:128)
Rockwool Eco-balance:
Energy
Used in life-cycle
Saved in life-cycle
Rockwool/Roxul insulation is one
of the major energy savers. A
typical 250 mm Rockwool loft
insulation product – manufactured
and installed in Denmark and used
over 50 years - will save 128 times
more primary energy than was
used for its production, transport
and disposal. The energy balance
becomes positive only 5 months
after installation.

CO2 emissions
This year’s sale alone of Rockwool insulation will, over 50
years, save more than 200 million tonnes of CO2
(this is more than today’s annual emissions from the Netherlands)
