Achieving Net Zero: Smarter, Sustainable Building Solutions

Hello, Champions of Net Zero!

The world of energy is poised for a monumental transformation by 2030, catalysed by an increased reliance on renewable resources, the integration of hydrogen, and significant advancements in energy storage and AI-driven optimisation. As we navigate this evolving landscape, one thing is abundantly clear for building operators: adapt to these changes or risk obsolescence. The ambitious net-zero goals set by the UK and EU further intensify the pressure on the building sector, recognised as one of the continent’s largest polluters. However, amid these challenges, smart technologies emerge as a promising pathway towards decarbonisation.

Digital innovations are not merely enhancing the functionality of buildings; they are fundamentally reshaping them into more efficient, sustainable, and comfortable environments for occupants. From occupancy-based smart controls that adjust heating, ventilation, and air conditioning (HVAC) systems to energy-saving modes during unoccupied periods, to advanced data analytics driving informed decision-making, the potential for transformation is immense. Even minor interventions can lead to significant operational cost reductions—up to 22% on low-occupancy days—illustrating that optimising electricity consumption, which currently accounts for 34% of total final energy consumption in buildings, is not just beneficial; it is essential.

Driving a Low-Carbon Future with Sustainable Buildings

As we strive towards the EU’s target of achieving net zero by 2050, decisive action within the building sector is imperative. Fortunately, many forward-thinking operators are already embracing smart technologies, laying a robust foundation for a sustainable future. The UK green building market exemplifies this momentum, projected to soar from £5.09 billion in 2024 to an impressive £13.2 billion by 2033. This growth signals that a significant shift in practices is already underway. However, it is important to note that this transition encompasses more than just adopting best practices; it requires a commitment to sustainable construction as urban populations expand and new developments emerge.

To facilitate this shift, building owners must gain increased visibility into their operations. Without a comprehensive understanding of energy consumption, usage patterns, and areas of loss, meaningful reductions in energy use remain elusive. The climate challenge is fundamentally an energy challenge, making intelligent technologies indispensable in providing insights that drive efficiency and sustainability.

For existing buildings, retrofitting with smart technology is not only feasible; it is becoming increasingly straightforward and cost-effective. The deployment of low-cost Internet of Things (IoT) sensors throughout a facility can yield real-time data on occupancy, temperature, air quality, and energy consumption. When integrated with a robust software management system, this data empowers operators to make informed decisions that optimise energy consumption and streamline maintenance processes. By leveraging real-time insights, operators can reduce workforce requirements, tighten budgets, and ensure the efficient use of space.

Consider, for instance, a facility grappling with inconsistent temperature control. By closely monitoring heat distribution, operators may discover that a specific room is inadequately insulated. Rather than relying on assumptions or incurring the expense of a comprehensive audit, they can act swiftly—installing high-quality, sustainable insulation to enhance thermal performance. This proactive approach not only improves comfort but also contributes to overall energy efficiency.

As smart technologies continue to evolve, buildings themselves will become increasingly adaptable. Rooftop solar panels, wind turbines, and microgrids can seamlessly integrate into existing infrastructure, reducing reliance on external energy sources. Furthermore, maintenance will transition from scheduled servicing to predictive, needs-based interventions, ultimately cutting costs and enhancing operational efficiency. At its core, the transition to smart buildings represents a pivotal step towards a sustainable future.

Finding Efficiencies Through Smart Tech

The impact of smart technologies extends far beyond building operations; the construction sector itself is undergoing a profound transformation, driven by advancements in AI and Generative AI (GenAI). From the initial design phases to on-site workforce management, AI is redefining how structures are conceived, constructed, and maintained. By equipping architects with tools to digitally model buildings before breaking ground, these technologies help minimise waste and enhance sustainability.

Material production is similarly benefiting from AI-driven efficiencies. Within the construction realm, digital procurement is streamlining supply chains, ensuring optimal resource utilisation. Moreover, automated quality control advancements are improving sustainability—concrete slabs can now be scanned for imperfections prior to installation, significantly reducing material waste.

Beyond the construction phase, digital twins are proving invaluable for ongoing efficiency enhancements. These virtual replicas allow operators to simulate various scenarios, testing energy-saving measures before implementing them in the real world. A noteworthy example comes from the University of Liverpool, which employed a digital twin to evaluate refurbishment strategies, resulting in a remarkable 23% reduction in energy consumption for one campus building—translating to an annual cost saving of £25,000.

Even after a building becomes operational, smart technologies continue to refine its performance. Sensors monitor critical metrics—such as temperature, lighting, and air quality—adjusting systems dynamically based on pre-set criteria. Over time, machine learning algorithms analyse this data, identifying patterns and fine-tuning performance. This continuous cycle of improvement enables operators to achieve peak energy efficiency with minimal manual intervention. As automation increases, energy waste decreases, allowing building owners to focus on other areas that enhance sustainability and long-term asset value.

A Blueprint for the Technological Age

For building operators, data is the key to unlocking efficiency. Modern AI and machine learning systems continuously analyse historical trends, growing more precise over time. The benefits are extensive: predictive maintenance extends the lifecycle of elevators, escalators, and HVAC systems; occupant comfort improves as buildings learn user preferences; and workplace productivity rises due to optimised environmental conditions.

Moreover, facility owners are witnessing a shift in the design and maintenance of electrical systems. Digital twins empower engineers to model power infrastructure in a virtual environment before physical implementation, significantly reducing design flaws and inefficiencies. Additionally, the concept of the “live digital twin” ensures that a facility’s virtual model remains dynamically updated with real-time operational data. This continuous optimisation enables facility managers to plan future upgrades with precision—whether integrating renewable energy sources, implementing electric vehicle (EV) charging stations, or scaling up power capacity to meet rising demand.

While there is no one-size-fits-all solution for smart buildings, the essential factor lies in connectivity: the more systems that are brought online through IoT devices, the greater the potential for efficiency gains. By iteratively scaling from basic monitoring to fully autonomous building management, operators can future-proof their assets without incurring significant upfront costs.

The Path to Net Zero

In the UK, several building operators are already showcasing the potential of smart technologies. Take Sidara, a multinational design, engineering, and construction firm, for example. At its 150 Holborn headquarters, over 650 IoT devices gather and process data from more than 60,000 data points. Through smart building controls, these systems monitor environmental conditions, occupancy patterns, and energy consumption—enabling precise adjustments that drive efficiency.

The results speak for themselves. Meeting rooms remain in a resting state—automatically lowering HVAC, lighting, and plug loads—for an impressive 76% of business hours, thanks to occupancy-based controls. Over a four-week monitoring period, these measures resulted in a remarkable 22% reduction in energy use and carbon emissions during low-occupancy days. Importantly, these efficiencies were achieved without compromising indoor air quality; CO₂ levels, humidity, and volatile organic compounds (VOCs) all remained within optimal ranges, demonstrating that sustainability and occupant well-being can indeed coexist.

Financially, the returns are equally compelling. Sidara estimates a two-year payback period for its smart building investments, with additional savings anticipated as HVAC components undergo further optimisation. They are not alone in this endeavour; according to Deloitte’s 2025 commercial real estate outlook, AI is set to play an even more significant role in shaping the future of both commercial properties and data centres. As the race to net zero accelerates, smart buildings will be pivotal in minimising the built environment’s carbon footprint—ensuring a more sustainable and resilient future for generations to come.

In conclusion, as we embark on this journey towards net zero, the integration of smart technologies into our buildings is not merely a trend; it is a necessity. With the right tools and strategies, we can reshape our built environment into one that is efficient, sustainable, and responsive to the needs of its occupants, ultimately contributing to a healthier planet.
