In line with COSATU’s resolution for unions to take “reasonable steps to reduce each affiliate’s carbon footprint”, the National Union of Metalworkers of South Africa (NUMSA) has refurbished its regional office in 32/34 Eloff (cnr. Frederick St) Street in Johannesburg’s central business district (CBD).
The building is retrofitted with a 30 kilowatt peak (KWp) solar panel; motion and ultra-sonic sensors; low-energy fluorescent lighting; and a central control system that has the ability to switch on lighting and air conditioning on all the floors at preselected times.
The air conditioning system has inverters that have the ability to modulate compressor speed and that has soft start features to reduce power consumption by 50%. [For a technical note on the renovations click here].
