As plans for South Africa’s new 4IR-ready smart cities begin to take shape, attention is increasingly shifting to construction – particularly how smart technology can be implemented to ensure energy efficiency, safety and sustainability in commercial buildings. BUILDING A SMARTER, SAFER AND MORE SUSTAINABLE SA STARTS WITH SMART BUILDINGS

printers may draw excess power unnecessarily when left on overnight or throughout the day. Install ing smart plugs can make a big difference in this regard, shutting devices off when not in use and l imiting how much power is used in standby modes. An added energy-saving bonus of install ing smart solutions in an office space is that it is possible to track and monitor where and how much power is being used, and to have full control from a remote smart device, allowing for better consumption management. It also helps management to make more informed decisions about equipment and devices being used in the office, and the need to change to models with better energy ratings. Smart safety and security The last two years have been challenging for businesses, having faced financial challenges as a result of lockdown, a decl ining local and global economy, nationwide lootings and unrest resulting in many businesses being burned down, as well as ongoing power cuts affecting operational efficiency and the bottom l ine. Added to this, South Africa was recently named the third most dangerous country in the world, as well as having the third-highest number of cybercrime victims in Africa. This all adds up to a need to adopt both physical and digital security measures to safeguard the well-being of building occupants and businesses. “In smart buildings, adaptive evacuation sign systems would form an integral part of an overarching smart l ife safety and building security system so that during a fire, for instance, occupants are directed away from danger and towards the safest exit, based on real-time information del ivered through integrated heat sensors and smoke detectors,” says Gopal. From a cyber security point of view, it’s worth pointing out that integrated smart technology increases the risk of cyberattacks on building infrastructure. This is the nature of l iving and working in an increasingly connected world. Data encryption is key in smart buildings, ensuring connections and communications are secure. “The biggest barriers to smart building adoption do not come down to a lack of available technology. Connectivity infrastructure, education and awareness, and an enabl ing regulatory environment are the main obstacles standing in the way of more wide-scale adoption. Once these are overcome, we are sure to see a mushrooming of smart buildings across the country, helping to real ise the dream of developing smarter, safer, and more efficient cities,” concludes Gopal . 

A nd while the conversation around the development of smart cities is still happening in future tense, the technology and opportunity already exist to turn office spaces, warehouses, retail sites and even hospitals into smart hubs. This means that businesses and other entities can start benefiting from technology that allows them to harness the energy, safeguard building occupants, and ensure the longevity of capital infrastructure. “As the national power util ity struggles with ageing infrastructure and inabil ity to meet demand, businesses simply can’t afford to rely solely on the grid to power their operations,” says Dean Gopal , Product Manager of Eaton’s Life and Safety Division for Africa. “Commercial players are also responsible for contributing positively to the country’s sustainabil ity goals and taking steps to reduce environmental impact. Optimising buildings to ensure energy saving is a key part of this, and the cost-saving certainly doesn’t hurt either.” Smart changes for energy savings Automation ensures more efficient use of resources. For workspaces, this means that power-intensive equipment, appl iances, and devices necessary for the daily running of a business can be better managed to prevent high energy consumption. These include HVAC (heating, ventilation, and air conditioning) or central air systems, which typically draw a great deal of power to operate. Install ing a smart thermostat, for instance, allows you to control temperatures from a smart device, setting the system to heat or cool on a schedule to save electricity, or to respond to the weather. Automated l ighting that operates in conjunction with occupancy and vacancy sensors help keep electricity costs down too, detecting when people are in a room or area of the office as well as when they’ve left, switching l ights on or off accordingly. Plug load devices such as computers, monitors and
