B Keywords – buildings; chromogenic technologies; electrochromic glazing; energy savings

An important feature of modern architecture is the widespread use of transparent fac¸ades.

Various architectural aspects have primarily motivated the use of glass nowadays.

Typically, the aim of admitting more natural daylight through glazed fac¸ades and

simultaneously providing indoor comfort is not always achieved. In particular, the focus

is currently on the air-conditioning loads in buildings owing to their rapid growth.

Extended glazed areas in buildings increase the cooling requirements, but on the other

hand very small windows lead to bad indoor comfort and hence poor job satisfaction

with subsequent poor job performance. Thus fac¸ades with demand-oriented or variable

throughput control of visible light and solar energy flux are required.
