Transcript
Worldwide, 30-40 % of all primary energy is
used in buildings
In the UNECE region, buildings cover
approximately 35 % of the total energy
consumption
CO2 emissions from buildings
are expected to rise of
140 % cent by 2050
Worldwide energy consumption in buildings is
expected to grow of 45% from 2002 to 2025.
2/3 of energy consumption in buildings is used for
heating and cooling
Worldwide, 111 million people
are employed in the building
and construction sector
The average new U.S house is 45 % bigger than
it was 30 years ago
Between 1985 and
1997, the average size
of a European home
increased from 83 sq.
metres to 87 sq.
metres
2,5 million households in the world use solar
lighting systems
80-90 % of the total energy used during the lifespan of
a building is consumed during the use phase
From 25 % to 40 % energy savings may be reached in
the housing sector
After buildings, the transport sector is the next largest
source of CO2 emissions
80 % of energy is used in small households
<1000 sq.m / Europe.
Thus, there lies the largest saving potential
In France, the government has decided to refurbish all its
public buildings by 2012 in order to cut the energy
consumption by almost 40% by 2020
By using well-proven energy efficiency techniques,
70 to 90 % of a building’s energy need for heating or
cooling can be cut.
Energy expertise is almost nonexistent within
financial institutions
Investments in improved energy efficiency in buildings
could generate an additional 2 - 3.5 million green jobs
in Europe and the United States alone
Typically, a low energy building uses at least 50 % less
energy than standard buildings.
Passive housing reduces energy consumption with
90 % compared to ”conventional housing”
No other sector offers a cheaper way to cut
emissions and save energy than the
building sector
Renewable energy generates more jobs than
employment in fossil fuels
Certain countries have 50 % more energy loss than
other richer countries of the region.
In low income countries, the residential sector often
represent over 90 per cent of all CO2 emissions from
buildings
2.3 million people have in recent years found
new jobs in the renewable energy sector alone
Out of more than 3000 CDM projects in the pipeline as
of May 2008, only 6 seek to reduce energy demand in
buildings
The building and construction typically provides
5-10 % of employment at national level and generates
5-15% of the GDP
In Germany for example, environmental technology is
to grow fourfold to 16 % of industrial output by 2030
In 2030, biomass use will still represent over half of the
residential energy consumption in developing
countries
40-50 % of the total flow in the global economy is used
for the manufacturing of building products and
components
