The 13th annual IAB Bookmark Awards took place today in a prestigious virtual celebration. Hosted by the multi skilled Selae Thobakgake and Merica Monamodi; the most thrilling and innovative digital marketing campaigns of the past year were announced.
The winners of the 11th edition of The Radio Awards were announced on today, Friday 30 July 2021, in an online awards ceremony hosted by comedian Loyiso Madinga. A total of 80 winners were celebrated across 30 categories.
Construction on The Capital Mbombela's R205m project, set to be a game-changer on the city's hotel and accommodation industries, is well underway with an anticipated hotel opening set for November 2021.
"The city hasn't seen any significant new additions to its hotel repertoire since development ahead of the 2010 FIFA World Cup projects," says Marc Wachsberger, managing director of The Capital Hotels and Apartments.
"Its status as a leading city in Mpumalanga, at the heart of the province's tourism and agriculture sectors, means that the time is perfect to build an exciting new offering that will be appealing to tourists and corporates alike."
According to a new NielsenIQ report, South Africa's latest liquor ban equated to a loss of R7,6bn during the four weeks it lasted (based on average sales - 13 weeks to end of May 2021 of R1,9bn per week).
The unpredictability and increases in the cost of electricity renders Solar Photo Voltaic (PV) an extremely viable alternative source of energy. Solar PV prices have dropped dramatically in recent years whereas the output power and efficiency per PV module ("panel") has conversely increased.
As more and more buildings are equipped with PV, facility managers need to ensure that these installations are correctly maintained. Below are some guidelines for PV system maintenance:
- Clean PV modules on a three-monthly basis using only water and a squeegee. No high-pressure hoses or cleaning detergents are necessary. It is paramount that safety regulations are adhered to. Therefore, insist that the installer provides adequate access, walkways and railings required for safe maintenance.
- Annual or bi-annual electrical checks for hot spots (infrared inspection), signs of heat discolouration of cabling and a check for exposed wires should be done. Specialist measurements of the insulation resistance, I-V curve performance and inverter tests should be carried out by the Solar PV installer.
- Annual retorqueing of all PV modules must be done along with an inspection of the mounting structures for signs of corrosion. If a ballasted system is used, the ballast blocks must be checked for cracks and chips, especially if they are installed over a subframe. The positions of the ballast blocks are determined based on the wind loading calculations and the ballast weight, it is therefore important that this weight distribution is maintained.
- Replace damaged Solar PV modules as soon as possible as the output of the entire string of PV modules connected in series will be affected. It is advisable to replace the PV module with one of the same technology (i.e. mono-, poly-crystalline or thin film) and an output that is equal or larger. If in doubt, contact a reputable Solar PV installer.
Solar PV Plants that are well engineered can be a great asset to a building that helps facility managers to:
Reduce the building operating cost.
Predict the cost of future electricity.
Provide a reliable source of power.
