About SiGA Wolfsburg
SiGA GmbH & Co. KG is a regionally significant provider of system solutions in the heating, ventilation and air conditioning (HVAC) sector as well as in building management, headquartered in Wolfsburg. Founded in 2006, the company offers complete building automation: from planning and consulting through execution and coordination to support and maintenance. In doing so, SiGA creates control schematics, function lists and automation strategies as well as software and visualizations for automation stations and building control systems. Circuit diagrams and cable lists are produced with the CAD systems E-Plan and WS-CAD; switchgear construction and electrical installation work are coordinated and carried out. In the field of system integration, the company links the entire technical building services across trades, for example in the areas of security, Internet Services, heating and energy management. With the GEG package, SiGA supports building operators in meeting the requirements of the Building Energy Act (§ 71a), from feasibility analysis through cost determination and funding application to planning and monitoring. Customers include BraWoPark, VfL Wolfsburg, Volkswagen, the City of Wolfsburg and the Lilienthalhaus Braunschweig.
