District heating
(and cooling)
systems
Allows to transport centralized
produced heat by
cogeneration, renewables and
or waste heat into city centres
with a high urban density

Energy labelling –
Example CasaClima Agency
The CasaClima Agency, born in 2002, is an
independent public society from South Tyrol
(Italy) which operates as a certification body
for the energy efficiency of the construction
sector.
The main goal of the
agency is to ensure the
quality of the work at
every step of the
process, and puts a
special emphasis on
the performance of all
actors taking part in
the process of
construction.
