Thanks for the invitation from Prof. Tong Yang from the University of Nottingham-Ningbo Campus (UNNC) for a presentation of classroom acoustics to his colleagues and students on April 30, 2014. Dr. Siu-Kit Lau has a very good discussion with the professors and students in UNNC. He has visited their Centre for Sustainable Energy Technologies (CSET), which is the first “zero net energy building” in China (see photo), and also the facilities in Mechanical, Materials and Manufacturing Department. UNNC have a good team and facilities for green building research and education, as well as for acoustics. Dr. Lau also enjoyed his discussions with Profs. Rosangelar Tenorio and Dunant Halim.
