Atop the gymnasium roof a 112kW solar PV array is installed . Here too the plant deck for the gymnasium indicating the packaged VRF system and ducting to-and from the building . application of the content of these international treaties is considered negligent .
The gymnasium posed the most significant challenge in the HVAC design for this project , purely due to its sheer size – a monstrous void that houses various possible indoor activities and along with that – variable occupancy . Attached to the gymnasium itself is something similar to a minuature version of a gym or health club circuit , and the HVAC system installed there needed to run independently on its own AC system when the main gymnasium was not being used .
Technical difficulties that needed to be addressed in this project , and specifically under the changes in regulations imposed by the global Coronavirus pandemic that has caused severe issues with health and indoor air quality , in June 2020 the South African government issued a gazette ( 43400 ) that specifies all return air must be filtered through high efficiency particulate filters ( HEPA ) which provide a 95 % effective filtration at 0.3 microns . A custom sterilisation system ( described above ) was therefore designed and supplied to meet these requirements in the gymnasium .
UNIQUE ELEMENTS AND EFFICIENCY The custom system that has been installed in the gymnasium makes it one of the most advanced in the country – there is only one other system like this that is operating at a hospital in Klerksdorp in the North West Province , with the same
