Sustainable construction trends to watch for in 2026

Architecture, engineering, and construction firms are expected to adopt new strategies, technologies, and materials to reduce carbon emissions, minimize waste, and support more sustainable building practices in 2026 — especially in markets where clients and regulatory bodies make sustainability a priority.

Across their full lifecycle, buildings remain one of the biggest contributors to both greenhouse gas emissions and waste generation. The construction and operation of buildings account for roughly one-third of global greenhouse gas emissions, while construction and demolition debris represented 30% to 40% of the world’s total solid waste stream in 2022.

However, meaningful change is unlikely to happen at scale unless governments, developers, and property owners actively demand it.

As Eamonn Connolly, director of engineering at McHugh Construction in Chicago, explained, what ultimately gets built is determined by what regulations require and what clients prioritize. At the moment, low-carbon construction is still not the industry’s main focus, and even when it is, the spread of best practices remains slow.

The construction sector has traditionally been cautious when it comes to adopting new methods, including sustainability initiatives. Even so, progress is being made. As more companies, suppliers, and professionals gain experience with low-carbon approaches, they become more capable — and more willing — to support and implement them.

For architecture, engineering, and construction (AEC) firms, incremental improvements are no longer enough. The industry needs to embrace approaches that create deeper, more systemic change. Below are four sustainable construction trends to watch in 2026 — trends that may not be entirely new, but are becoming increasingly influential.

Adapt, don’t build

Architects often point out that the most sustainable building is the one that never has to be built. Avoiding new construction reduces the embodied carbon associated with extracting raw materials, manufacturing products, transporting them, and assembling a structure. That makes the reuse of existing buildings one of the most effective sustainability strategies available.

A strong example of this can be seen in Detroit’s redevelopment efforts, where many projects involve buildings listed on local, state, or national historic registers. In many cases, the original craftsmanship and materials are either too expensive to replicate today or no longer available at all. Retrofitting these structures with modern, energy-efficient systems can significantly improve performance, while preserving the original building envelope often saves both time and money compared to ground-up construction.

Adaptive reuse takes this concept further by repurposing older buildings for entirely new uses. McIntosh Poris, a Detroit-based architecture firm, has played a major role in transforming outdated structures instead of demolishing them. Its projects include converting a 1925 bank building into the techno nightclub Panacea, turning the former Detroit Fire Department Headquarters into the boutique Detroit Foundation Hotel, and redeveloping Fisher Body Plant 21 — originally opened in 1919 and abandoned in 1993 — into a mixed-use residential development with retail and coworking space.

Across the U.S., adaptive reuse generated around 25,000 new apartments in 2024, representing a 50% increase year over year. Nationwide, this type of development is gaining momentum, with a record 181,000 apartments currently in progress, many of them created from office buildings that remained underused after the pandemic.

A major driver behind this growth is the role adaptive reuse can play in expanding affordable housing. Reusing existing buildings can lower both construction costs and development timelines, especially in highly desirable urban locations. For example, at least 20% of the units at Fisher 21 Lofts will be reserved for residents earning 80% or less of the area median income. Tax incentives and public funding programs can further improve the financial viability of these projects, especially when they include mixed-income housing and contribute to neighborhood revitalization.

Design around climate

Rather than relying on generic building formulas, climate-responsive design focuses on creating energy-efficient architecture based on a building’s site conditions and surrounding environment. This approach considers factors such as sunlight, wind patterns, orientation, and local climate to reduce energy demand naturally.

Designers use building placement, shading strategies, and carefully selected materials to either capture or block solar heat and wind. The goal is to reduce dependence on mechanical systems for heating, cooling, ventilation, and lighting.

For example, natural ventilation can significantly lower the need for air conditioning. To achieve this, Foster + Partners designed the Bloomberg European Headquarters in London with a distinctive “breathable” façade. Its automated bronze louvers open and close to regulate airflow, and when paired with a central atrium, they help reduce energy use by approximately 35% compared to a conventional office building.

Over time, climate-responsive design has evolved into a more holistic, technology-driven architectural approach. Google’s Bay View campus in Silicon Valley, which opened in 2022, reflects this shift. The campus includes a large-scale geothermal system, solar-integrated roofs, 100% outside-air ventilation, abundant natural daylight, native landscaping, and net-zero water use.

Despite these examples, the overwhelming majority of the world’s building stock still requires major upgrades before it can truly be considered climate responsive.

Reenvision glass

The popularity of sleek glass curtain walls and bright, open interiors explains why glass now makes up more than half of the exterior surface area on many modern skyscrapers. However, this design preference often comes at the expense of energy efficiency, since glass traditionally provides relatively poor insulation.

That said, several innovations are helping make glass façades far more efficient:

• Low-emissivity (low-E) coatings that better regulate heat transfer.

• Insulated glass units that seal two or three panes together to reduce heat loss.

• Argon or krypton gas fills between panes, which slow heat transfer more effectively than air.

The next step in this evolution is the development of energy-generating windows that capture light and convert it into electricity. One example is the technology from NEXT Energy Technologies, which has been installed at Patagonia’s corporate headquarters in Ventura, California.

Equally important is improving the sustainability of how glass itself is manufactured. Producing glass requires mining raw materials such as sand, soda ash, and limestone, while also operating furnaces at temperatures around 1,500°C, often powered by fossil fuels.

To reduce this environmental impact, manufacturers are increasing the use of recycled glass content, adopting cleaner oxy-fuel furnace technology, improving furnace efficiency, and investing in carbon capture systems. Because glass can be recycled indefinitely, it has strong potential to become a truly circular material if production processes continue to improve.

Optimize with AI

According to a survey of 235 contractors conducted by Dodge Construction Network, many industry professionals believe that artificial intelligence will eventually transform construction — once the sector more widely adopts the digital tools that make AI useful.

That transition may take time. In Yooz’s 2023 Technology in the Workplace survey, construction workers ranked their own industry as the least technologically advanced among those surveyed.

Even so, the value of AI is becoming increasingly clear. Autodesk’s 2025 State of Design & Make: Spotlight on Construction report highlights several major sustainability-related uses for AI, including:

• Supporting data-driven decision-making.

• Improving and analyzing supply chains.

• Enhancing sustainability reporting.

• Optimizing energy performance and efficiency.

• Reducing material waste.

Concerns around data privacy and security still exist, but architects and engineers are already using generative AI to test alternative structural designs that use the least amount of material while still maintaining safety and performance.

AI can also be trained to predict the exact quantity of materials needed for a project, helping eliminate over-ordering and reducing both waste and cost. By measuring the embodied carbon of different materials — including modern façade solutions such as FRP panels and exterior FRP panels — AI tools can also help teams make decisions that lower a project’s overall carbon footprint.

Another major development is the use of digital twins — virtual models of physical buildings or infrastructure assets. These systems rely on AI to simulate building performance from the design stage through operation and even end-of-life scenarios. When updated continuously with data from embedded sensors and other sources, digital twins allow building managers to test changes, predict performance, and improve outcomes.

For example, a digital twin of Heathrow Terminal 5 is used to simulate energy use, airflow, and thermal comfort, helping improve operational efficiency and post-occupancy building performance.

Double down

By 2050, the global building stock is expected to double in size. The tools, materials, and strategies needed to reduce the carbon impact of future buildings already exist — what’s missing is stronger demand and broader adoption.

As Connolly noted, the construction industry is not lacking solutions; it is waiting for a clearer signal from clients, regulators, and markets to do more.

The sustainable construction trends to watch in 2026 make one thing clear: the future of building depends less on isolated upgrades and more on a broader shift in priorities. From adaptive reuse and climate-responsive design to high-performance glass systems and AI-driven optimization, the industry already has access to many of the tools needed to cut emissions, reduce waste, and create more resilient buildings.

What will determine the pace of progress is not a lack of innovation, but the willingness of governments, developers, and clients to demand better outcomes. As the global building stock continues to expand, firms that commit to sustainable practices now will be better positioned to meet future regulations, reduce lifecycle costs, and contribute to a built environment that is both efficient and responsible.
