4 countries control most of the world’s oil reserves
3 countries control most of the world’s gas reserves
Energy demand is growing, reserves are declining
The last oil

Climate change – where should we start?
77
33% of all energy in EU is used for transport
26% of all energy in EU is
used by industry
41% of all energy in EU is used by buildings
2/3 of energy consumption in buildings is used for heating,
cooling and ventilation.
Buildings are the biggest energy consumer and CO2 polluter
88
Where do you use most energy?
99
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
1010
Buildings for the future?
A building can last 100 years or more.
Short-sighted energy inefficiency is costly.
1111
More power plants or less energy waste?
Source: EU
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

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
2121
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
Key recommendations

Buildings account for some40% of energy consumptionAnd a major share of manmade CO2 emissions
The fight against
climate change starts at home
Most of this expensive energy is wasted
Mostly for heating, cooling and ventilation

The world leader in stone wool Global no. 2 in insulation Turnover USD 2.8 billion 8000 employees 21 factories in 14 countries

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)
Source: FORCE TECHNOLOGY/dk-TEKNIK
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.

Saved in life-cycle

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)
