The creation of cooling degree (CDD) and heating degree day (HDD) climatic maps for South Africa

Author: Conradie, Dirk CU ; Van Reenen, Tobias H ; Bole, Sheldon Date: Dec 2015 The current six climatic regions map used in the SANS 204 (2011) South African National Building Standards does not optimally support quantified design decisions within the built environment. It also does not give an indication of the amount ... Read more

Developing demand driven ventilation criteria for airborne infection control in congregate spaces

Author: Van Reenen, Tobias H ; Grobler, Jan-Hendrik Date: Jul 2020 This article presents the case that 12 air changes per hour (ACH) does not provide adequate control against the amplification of disease in different indoor congregate settings. It proposes an occupancy and risk-based algorithm for determining ... Read more
Effectiveness of a low-cost UVGI chamber for decontaminating filtering facepiece respirators to extend reuse

Author: Singh, T ; Duba, T ; Muleba, L ; Matuka, OD ; Glaser, Daniel ; Ratshikhopha, E ; Kirstena, Z ; Van Reenen, Tobias H ; Masuku, Z ; Singo, D Date: Dec 2022 In emergencies like the COVID-19 pandemic, the reuse or reprocessing of filtering facepiece respirators (FFRs) may be required to mitigate exposure risk. Research gap: Only a few studies evaluated decontamination effectiveness against SARS-CoV-2 ... Read more
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
The importance of integrated system design for the effectiveness of portable air cleaners in airborne infection

Author: Van Reenen, Tobias H ; Salie, F ; Jensen, P ; Nardell, E ; Grobler, Jan-Hendrik Date: Dec 2013 The results of the recent study into the effectiveness of portable air cleaners (PACs), as an infection control measure against TB, delivered unexpectedly low results. That finding initiated a further study to understand the contribution of ... Read more
Indoor environmental quality and building energy efficiency

Author: Van Reenen, Tobias H Date: Mar 2014 Buildings are an expression of our need for shelter which is driven by a host of factors including the need for comfort and security. Our perceptions of, and responses to, our buildings are inseparable from the ways in which our buildings ... Read more
An investigation into turbine ventilators as a potential environmental control measure to minimise the risk of transmission of TB

Author: Salie, F ; Poluta, M ; De Jager, Peta ; Abbott, G ; Baloyi, N ; Van Reenen, Tobias H Date: Oct 2012 The subject of this research project is to review and study the effectiveness of natural ventilation design assisted by a turbine ventilator, introduced to minimise the risk of transmission of airborne pathogens like TB.
