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.
