Hybrid design strategies for recommended indoor air quality: The case of Hillside Clinic, Beaufort West

Author: Van Reenen, Coralie A ; Van Reenen, Tobias H ; Nice, Jako A ; Motsatsi, Lorato L ; Conradie, Dirk CU ; Van Wyk, Llewellyn V ; Bhikoo, Bhikoo, J ; Kuschke, U Date: Oct 2020 The high occupancy that typically occurs in South African clinics, and the accompanying risk of airborne infection, make ventilation and thermal comfort particularly important considerations in the design. Passive (natural) ventilation offers ... Read more
Maximising the sun

Author: Conradie, Dirk CU Date: Aug 2010 South Africa is blessed with some of the best quality solar radiation in the world. In the light of this many exciting opportunities exist to utilize the sun to its full potential in the design of energy efficient buildings. Passive solar ... Read more
Performance of a solar chimney by varying design parameters

Author: Kumirai, T ; Grobler, Jan-Hendrik ; Conradie, Dirk CU Date: Aug 2015 Trombe walls and solar chimneys are not widely used or well known in South Africa. A previous Green Building Handbook article described the University of Fort Hare teaching complex in East London (Stratford, 2012) that inter alia used a trombe ... Read more
The performance of innovative building technologies in South Africa’s climatic zones

Author: Conradie, Dirk CU Date: Mar 2014 This chapter quantifies the thermal performance of a cross section of Innovative Building Technologies (IBT) in South Africa's climatic zones. An IBT in the context of this chapter means a South African Agrément certified building system, but ... Read more
