Global construction and AEC activity is expected to grow 3.0% in 2025, but the carbon story around buildings is far less steady. Lifecycle emissions are often dominated by operations and maintenance, while energy demand and delivery systems keep shifting across countries. This post brings those building, materials, labor, and software signals into one set of statistics so you can see where architecture decisions lock in both performance and risk.
Key Takeaways
- 3.0% expected global growth rate for the AEC industry in 2025 (Oxford Economics AEC outlook, 2025 forecast)
- 79% of AEC firms reported using BIM in some capacity, according to the 2023 AIA/Construction/ArchTech survey results compiled by Dodge Construction Network.
- 4.5% year-over-year growth in global construction software market value between 2022 and 2023 (industry research estimate), reflecting increasing spend on digital architecture and project delivery.
- Building operations and maintenance represent the largest share of lifecycle carbon emissions for many building types, often exceeding embodied carbon depending on design and lifespan (IPCC AR6 WGIII synthesis on emissions breakdown)
- 37.1% of all energy-related CO2 emissions in the United States came from the buildings sector in 2023, split between residential and commercial buildings
- 1,100 trillion BTU of delivered energy was consumed by U.S. buildings in 2022
- 40.7% of global final energy consumption was used by buildings in 2022
- 0.23% of global construction output was lost to rework due to design errors in a 2017 study of construction project performance
- A 2021 study found that BIM-enabled visualization can reduce design cycle time by 15% on average in sampled projects (peer-reviewed)
- A 2019 meta-analysis reported that design coordination technologies can reduce clashes by roughly 10% to 50% across project types (peer-reviewed review)
- 6.2% median annual growth in U.S. A/E/C employment between 2022 and 2023 (BLS employment figures; A/E/C occupations)
- In the U.S., the architecture and engineering services sector employed 1.8 million people in 2023 (BLS employment series)
- The U.S. construction sector spent $1.57 trillion on new construction and repair in 2023 (US Census / BEA construction spending)
- In 2022, 60% of architects used project management software (PM tools) for at least some projects (industry survey)
- 65.2% of U.S. construction firms reported having difficulty finding skilled workers in 2022, reflecting labor tightness that directly affects architecture-led projects.
Buildings drive most carbon and energy use, so better design, BIM, and efficiency can cut emissions significantly.
