Building automation – impact on energy efficiency - Siemens ...

The consequences include an increase in storm winds and storms, damage to
crops and forests, an increase in the sea level as well as mudslides, droughts and
erosions – so for example, hurricane Katrina (New Orleans):
The Climate Change Report 2007 by the United Nations is calling for global action.
2.2 Primary energy consumption in Europe
<strong>Building</strong>s account for 41% of primary energy consumption.
Of which 85% is used for room heating and room
cooling as well as 15% for electrical energy
(in particular, for lighting).
Overall, buildings account for 35% of primary
energy use to achieve comfortable temperatures
and 6% for electrical energy. That amounts
to a significant portion.

2.3 Turning the tide – a long-term process
Europe has developed visions for a low-energy future and is intensely searching
for ways to implement the visions:
Vision for the future
We want to find ways to continue enjoying our lives in reasonable comfort, but using
less energy, and with fewer CO 2 and greenhouse emissions than today.
The scenario "Paths toward a 2,000 watt society" as part of Swiss energy policies
pursues goals that are similar to current efforts at the EU level.
