Source-derived summary

TAC is a Swedish-based building automation company in the fields of both energy and security. It also operates in other countries including the United Kingdom and the United States.

It was originally established in 1925 as Tour Agenturer in Stockholm.

TAC announced a name change of its parent company Schneider Electric in October 2009.

History

1925–1995

In the beginning, the company produced a product range focusing particularly on draught regulators and radiator valves.

It continued to develop its product range introducing the first transistorized heating regulator in 1962 and a computer-based system for climate control in 1974.

Tour Agenturer became Tour & Andersson in 1977 following a merger with AH Andersson.

Over the following years, Tour & Andersson extended its product range to include an integrated access control system and hotel management & signal system in 1980 and 1981 respectively.

In 1987 it released Micro 7, an IBM PC-based control system with an easier user interface than previously available. It was operated with a mouse in a similar fashion to modern-day computers.

Editorial analysis

Why this record matters

The phrase “swedish building automation company” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Critical limits

Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
