Buildings designed for intellectual and<br />
physical activities world-wide are equipped<br />
with automatic, intelligent control systems,<br />
shown in Figure 2, that act upon the<br />
functional installation systems to ensure the<br />

2 Main factors that contribute to the<br />
energy efficiency <strong>of</strong> buildings<br />
Researches made at global level show that<br />
the energy consumption <strong>of</strong> lighting systems<br />
is different in the case <strong>of</strong> buildings with<br />
different functions. Buildings designed for<br />
intellectual and commercial activities use<br />
up to 40-50% <strong>of</strong> the total consumed energy,<br />
while in the case <strong>of</strong> industrial buildings the<br />

achieve the state <strong>of</strong> comfort (thermal, air<br />
quality, acoustic and luminous) required by<br />
human activities.<br />

Permanently and constantly ensuring<br />
the comfort required by human activity<br />
(heating, air quality, acoustic and<br />
luminous comfort)<br />
percentage goes down to 20% (in this case,<br />
the structures that support the industrial<br />
process have a greater importance).<br />
Figure 3 shows that the only way to<br />
reduce the energy consumption <strong>of</strong> interior<br />
lighting systems is by implementing<br />
modern designs that are based on the<br />
integrated use <strong>of</strong> natural light and electric<br />
light.<br />
