The DNA of Smart Buildings: Past, Present, and Future

In my previous posts, we looked at the Smart Building concept and discussed digitisation strategies. In this, the last post of my series, we will look at sustainable digitisation journeys for old and new facilities alike.

The growing role of IT in Facility Management

2019 Digital Transformation Benefits Report

With the growth of Smart Buildings, it is no surprise that Facility Managers today are expected to be more IT-savvy. This poses several interesting challenges to the role of the Facility Manager. Firstly, the vast amounts of data generated is far too much to consume and understand with a siloed work approach and without tools and applications to assist. The integration of multiple systems provides predictive operational capability, reduces administrative tasks through automated reporting and alarming, and ultimately requires a quick transition from the aforementioned siloed mindset into a system-oriented approach. This is not the future – it’s today, and thereby creates a need to urgently train and upskill existing personnel. Furthermore, the challenges of security through connected systems, particularly when leveraging cloud-based services, requires an unprecedented level of network and cybersecurity awareness. Hence, the Facility Manager becomes key to the digital strategy, and the associated success in adoption.

Implementation in Older Facilities

IT networks form the backbone of any Smart Building. For older facilities, transitions to systems on an IP network may provide challenges, particularly around establishment of the physical infrastructure. Wireless network architectures may be more favourable to avoid disruptions in operations, but will also be constrained by the network reach and space layouts that could cause connectivity challenges. Multiple IT networks may also be required to securely host an array of systems.

Choice of the IT networks in older facilities also depends on the capabilities of the associated hardware generating data and controlling the building. Today, most high-end BMS have some form of wired IP-capability, with wireless controllers gradually appearing. However, advanced Smart Building technology like Space Utilisation solutions employ wireless sensors (e.g. LoRa, Bluetooth, WiFi, NFC, Zigbee). Therefore, depending on the level of investment and size of the facility, owners may wish to diversify the variety of IT infrastructure available.

Implementation in New Facilities

While newer facilities have greater flexibility over choice of IT infrastructure and technology, greater care should be taken that investment made does not get outdated within a short period of time. Moore’s law may be slowing down [1], but innovation isn’t, with networks becoming faster, and the cloud expanding in terms of both storage and analytical capabilities. Therefore, new facility owners need technologies that compliment business operations. It is crucial that buildings and systems are designed to suit their businesses and not the other way around. Bearing that in mind, network designers are best poised to provide a variety of IT infrastructure.

Equipping the facility with a basic array of environmental and occupancy sensors helps keep up with industry trends and evolving employee expectations. Small design implementations, like enabling expansion capabilities through a range of network ports, and widespread power outlets can have a huge impact on technologies invested in the future, and the costs associated with implementing the same. Maximising IoT devices and cloud connectivity further helps ensure a continuous assessment of operations, analyse cross-system data, and ultimately streamline building performance to improve occupier experience and comfort.

The Realistic Approach to Technology Investments

What do you do if your facilities have a mix old and new buildings? Most organisations are under a constant pressure on available funds, while being pressed to improve performance and enhance occupant experience. What is the realistic approach to technology investments in such cases?

Consider the case of Swansea University. The old campus was on an outdated BMS with limited analytical capabilities and integration with the power infrastructure. The new facility was designed with the latest high-performance BMS and Power infrastructure, sitting an IoT platform that could bring together multiple systems under a single architecture. What this system also allowed was the integration of operations of legacy and modern assets across the two campuses. Furthermore, an upgrade strategy for the older site was put in place that enabled the facility managers. Given the high levels of compatibility and the bespoke, modular nature of the new system, the upgrade or complete replacement of the legacy infrastructure can be done in parts and aligned with budget and planning cycles, as opposed to a one-off, costly investment. Swansea University represents a well-thought-out upgrade strategy for an older facility – read more about it here.

A Sustainable Path for Smart Buildings

Smart Buildings underpin the future of an energy-efficient economy. Facility Managers and Building Owners should note that a digital ecosystem is in the present. A lack of action today is only cause for pain tomorrow. Ultimately, Smart Buildings are not a pocket-draining investment – if done the right way with a clear vision, returns far outweigh costs.
