Smart cities and the sum of their parts

Business premises are one of the first places companies take stock of when assessing their electricity usage and the optimisation thereof. And rightly so, approximately 30% of global greenhouse gas (GHG) emissions, and 70% of energy consumption are attributed to buildings. Moreover, it is estimated that 30% of energy is wasted in buildings.

Coupled with our country’s much-talked-about volatile grid, buildings must become smarter. Also, as they become smarter, through the upgrade of existing premises and development of new, smarter buildings, we will steadily see the dawn of a new era, the smart city.

If a smart building is a collection of disparate systems seamlessly working together, a smart city is a microcosm of disparate environments, including smart buildings and the grid, operating as one organism.

Cities define a civilisation, which shines light on the human element. Thus, today’s push for a smart building to meet these people-centric objectives, such as wellbeing and social cohesion, will form a key part of the transformative journey to a smart city.

Start first

However, for us to realise smart cities, we must lay the building blocks and it starts with buildings. A holistic building management system (BMS) is the key to a smart building strategy as it overcomes many of the struggles that both service providers and owners face when establishing a smart building.

At Schneider Electric, our BMS offering is a collaborative Internet of Things (IoT) solution that features a scalable, secure and global architecture to make buildings of all types, smart.

It connects hardware, software and services over a digital IP backbone to help service providers and owners maximise building efficiency, optimise comfort and productivity, and increase building value.

And the grid?

If there is one driver that is going to become a vital part of our journey towards smart cities, it is electricity. The future relies on our ability to provide resilient electricity to the infrastructure within the smart city.

The grid’s ability to respond actively to surges in energy demand and supply will be a key enabler to realising our smart city vision. However, this also remains one of our biggest challenges, particularly with technology’s reliance on electricity.

Condition-based monitoring systems, for example, can lead to self-healing designs, which will in turn enable modernisation of the power system to an automated microgrid. Furthermore, smart grids will enable consumers to readily gain access to their energy data. This will enable them to make decisions autonomously on their energy consumption.

Let’s get real

To some, smart cities still feel like belonging to an advanced civilisation in a sci-fi movie. Not quite, already we are seeing developments such as Steyn City emerging as bona fide mini smart cities, which will or already feature entirely self-contained resources such as generators that protect its residents and tenants against power disruptions.

In South Africa, smart cities will likely be built on a smaller scale but the adage ‘lead by example’ will undoubtedly drive the country towards implementing smart buildings that will eventually lead to bigger smart cities.

As a country we need to keep on investing and believing in the future of smart cities with leadership in both public and private sectors forging the way towards smart buildings and cities that establish a future built on sustainability, resiliency, hyper efficiency and people-centricity.
