<p>Buildings represent 30 percent of total final energy consumption, and more than half of electricity consumption<sup>1</sup>.</p>

02

<p>The built environment is undergoing a major transformation with trends such as AI, smart energy management, predictive maintenance, etc.</p>

03

<p>ABB is supporting the sector in its transformation with a range of advanced technologies.</p>

The role of smart and sustainable buildings

Buildings are far more than enclosures of walls and roofs. They are the spaces where people live, work, play, rest and grow. Beyond protecting us from weather, noise, and pollution, they also express our identities: personal, social, and cultural. As they become smarter and more sustainable, these spaces are evolving from passive shelters to intelligent, energy-efficient and thriving environments. 

By 2050, over two-thirds of the global population - an additional 2.5 billion people - is projected to reside in urban areas, placing unprecedented strain on city infrastructures. As cities grow and urbanization continues, smart and sustainable buildings will play a crucial role in reducing environmental impact and making urban infrastructure more sustainable.  

However, according to the International Energy Agency (IEA), buildings are responsible for a staggering 30 percent of final energy consumption and are one of the largest sources of greenhouse gas emissions.

Smart buildings are a smarter choice due to three overarching ways they deliver next-level benefits: savings, security and sustainability.

 

Governments and enterprises worldwide are also playing their part in adopting green building certifications like LEED (Leadership in Energy and Environmental Design) and BREEAM (Building Research Establishment Environmental Assessment Method) to promote sustainability initiatives.

There are several megatrends leading to the transformation for buildings around the world:

AI and digital technologies optimizing building performance

<p>Advanced sensors and AI-powered BMS (building management system) are revolutionizing the way we manage energy in buildings. Smart systems now reduce waste and improve efficiency<sup>2</sup>, while taking care of peoples’ comfort and safety.</p>

Electrification (and smart grid integration to expand)

<p>From electrified HVAC to EV charging infrastructure, buildings are becoming key players in the energy transition. These technologies continue to reduce emissions but also enhance buildings’ resilience.</p>

Sustainability and energy efficiency are key priorities

<p>Enhancing energy efficiency in buildings is crucial, as they account for 30 percent of global final energy consumption and 26 percent of energy-related emissions<sup>3</sup>.</p>

Circular construction, materials and system components

<p>By recirculating used materials through harvesting, recertifying, and testing, construction projects can be delivered at a lower cost than by using virgin materials with equivalent performance criteria.<sup>4</sup></p>

The world is becoming increasingly urbanized

<p>68 percent of the world's population is projected to be urban by 2050.<sup>5</sup> Integrated management systems are helping buildings achieve optimal performance, from energy use to tenant comfort, with technologies that predict, adapt and learn.</p>

Digital connectivity

<p>Gartner predicts that by 2028 there will be over four billion connected IoT devices in commercial smart buildings, powered by telecommunications infrastructures, with 5G and High Efficiency Wi-Fi (6 or 6E) at the forefront.</p>

Challenges within the building industry

Policy, codes and regulatory gaps

<p>Many markets still lack building codes, retrofit mandates, or regulations that require/enable low-carbon design, grid-readiness (demand-response) or minimum digital/data standards, which creates uncertainty for investors and developers.<sup>7</sup></p>

Financing & high upfront costs

<p>Deep efficiency retrofits, on-site renewables, batteries and smart systems often require large initial capital and complex financing.<sup>8</sup></p>

Skills, supply-chain and workforce capacity

<p>Scaling retrofits and smart systems needs large numbers of trained installers but reports highlight shortages in trained labour and bottlenecks in manufacturing/installation capacity.<sup>9</sup></p>

Digital maturity, interoperability & data governance

<p>Many buildings lack basic digital instrumentation; where systems exist they’re fragmented (vendor silos, proprietary protocols), making portfolio-level optimisation and digital twins difficult.<sup>10</sup></p>

Electricity system & infrastructure constraints

<p>Widespread electrification (heat pumps, EV charging) and building-level flexibility depend on grid capacity, renewables and storage. In many regions the grid and market arrangements aren’t yet ready to integrate millions of smart, flexible buildings.</p>

Retrofitting complexity & embodied carbon trade-offs

<p>Existing building stocks are heterogeneous: deep retrofits are technically complex, disruptive and can incur high embodied emissions if not managed carefully.</p>

ABB solutions for smart and sustainable buildings

  

Renewable energy integration and storage

Smart buildings pave the way for the integration of renewable energy sources like solar panels, wind turbines and geothermal systems. To truly leverage their potential, we need solutions for storing excess energy generated during peak production times such as microgrids and energy storage systems. ABB's microgrid technology allows buildings to manage their own power generation and consumption, reducing reliance on the traditional grid and minimizing the impact of power outages.

Digital technologies

Integrating IoT in buildings is crucial for evolving property supervision and management methods. It gradually transforms traditional buildings into intelligent structures, capable of dynamically and efficiently addressing user needs and environmental challenges.
