Machine Laboratory The historic chimney and the adjacent water tower rising above the buildings of the Gdańsk University of Technology campus were created as part of the Machine Laboratory. Built in 1904 and based on the design by Hermann Eggertt and Albert Carsten, those buildings met the university's heating, water and electricity needs as well as offering more teaching space. The structure consisted of a basement machine room with an adjoining boiler-house, a chimney situated between them with an adjacent water tower and a set of rooms. The system was designed by Prof. Josse. This was the first peaking power plant in Gdańsk in 1945 serving the residents of the Gdansk district of Wrzeszcz. The laboratory was expanded and modernized in 1994–1997 and has retained many of its original technical features. Cooling tower The cooling tower and the machine operator building were erected close to the laboratory. The steel-frame cooling tower, 28m high, designed to work as a closed circuit system was built on a granite foundation behind the machine hall. The lower part is a cold sprinkler of an oval cross-section that served as a heat exchanger. A circular chimney was then placed on the oval cross-section to get a free flow of air. The dome of the cooling tower is crowned with a spearhead. Building of the Faculty of Electrical and Control Engineering The Institute of Electrical and Control Engineering (Elektrotechnisches Institute) was established in 1900–1904 and the building was designed by Hermann Eggertt and Albert Carsten. It consisted of four distinctive spaces and areas interconnected by a corridor: workshops and laboratories with a small auditorium hall, a machine hall (Drive Hall), an auditorium hall and laboratories, and the drafting hall with additional rooms. Today, the building is named after Prof. Kazimierz Kopecki. The building now houses large auditoriums, a renovated auditorium E1 and a historic auditorium E41 named after Prof. Stanisław Szpor. Following extensive renovation and restoration the latter was returned to its original appearance going back to 1904. Completed in 2011 the work of renovation, modernization and fitting the historic rooms with modern audiovisual and ICT equipment was funded by the project "Modern Auditoriums at Gdańsk University of Technology." One of the most interesting sculptures on the university campus can be found on the façade of the building. It shows a
