Trend Analysis: How are Renovation & Embodied Carbon Changing the Construction Value Chain?

The low carbon building market conversation has gone beyond energy efficiency alone and is taking a holistic look at the building lifecycle. While the critical issue of operational energy usage still exists, the "blind spot" of embodied carbon, such as emissions due to materials such as concrete, steel and aluminum, is now center stage. These 3 materials alone have 23% of global emissions. With embodied carbon expected to make up nearly half of emissions coming from new construction between now and 2050, the market is aggressively shifting to alternative materials.

This trend is most apparent in the development of the mass timber market, which was worth $1.3 billion in 2024. Despite wider economic headwinds in construction, North America low carbon building market saw 155 mass timber projects move forward in one year alone. At the same time the steel industry is being radically transformed with green hydrogen steel production predicted to reach 46 million tons by 2035. The trend is clear: The value chain is decarbonizing from the mine to the job site. Another enormous possibility is the concept of adaptive reuse. Data from the AIA 2030 Commitment indicates that 46% of the reported projects in 2024 were renovations. Architects and developers are also increasingly choosing to upgrade existing assets instead of demolishing and rebuilding, moving from the realization the greenest building is the one that is already here.

Future Landscape: Why Are Investors Betting Trillions On the Green Building Transition?

The financial sector has woken up to the point that climate risk is investment risk and capital is flowing. With issuances in excess of $1 trillion, the green bond market is heavily skewed toward the built environment with energy efficiency and green buildings representing 46% of the value of the green economy in public markets. In the financial sector investors are not just chasing virtue but returns. Green-certified buildings are selling for 8-12% more on resale, indicating a real exit strategy for developers who make an investment in sustainability.

However, there is still a large investment gap in the low carbon building market, which represents a huge investment opportunity for private equity and institutional finance. To achieve climate targets, there will need to be a doubling of annual energy efficiency investments to some $522 billion by 2030. In the European Union alone a cumulative investment of EUR1.2 trillion is needed to meet this goal: 2030 Energy Performance of Buildings Directive. This gap is the market potential. We are also seeing the democratization of this investment with households making up 60% of the efficiency investments globally, through mostly retrofits. The smart money is now pouring into companies that can scale retrofitting solutions (indeed the European renovation market alone is expected to grow at a CAGR of almost 20% through the end of the decade).

Technology Impact Analysis: How and Which Technologies and Milestones Effective at Displacing Fossil Fuels?

Technology in the built environment has moved past the phase of pilot projects to become mass-market, especially in the fields of electrification and digitalization. The heat pump has become the flagship technology of decarbonization of heating in the low carbon building market. While Europe experienced a temporary slump caused by energy pricing volatility, the United States and China experienced an increase in sales of 15% and 13% respectively in 2024. In the U.S. market heat pumps have just crossed a symbolic milestone when they outsold gas furnaces by 30% - the beginning of the end for fossil fuel heating in residential new build.

Beyond hardware, digital intelligence is unlocking value. The application of digital twins is now proven to lower operating costs up to 20% and the smart building market is growing at a double-digit rate. We are also witnessing the industrialization of green tech with ventures such as H2 Green Steel raising $4.5 billion to demonstrate that the decarbonization of heavy industry is possible. The milestone to be watched is "Zero-Carbon Ready" standard. With 100% of new buildings having to comply by 2030 to meet the objectives of the Paris Agreement, over the next five years we're going to see a scramble to implement the technologies to integrate on-site renewables, which currently are growing at too slow rates of 5% of final energy demand.

How Do Rigorous Certifications and Strict Policies Work As Market Accelerators?

Voluntary certifications and mandatory policies are playing the role of the "carrot and stick" to move the low carbon building market forward. On a voluntary basis, certifications such as LEED and BREEAM have become non-negotiable in prime real estate assets. BREEAM has passed 1 million asset certifications and LEED covers more than 29 billion square feet worldwide. These certifications are evolving as well; for example the 200% increase in BREEAM certifications for data centers in 2024 indicates the extent to which niche asset classes are joining in with the movement. The data shows that certified buildings don't only save carbon, they protect asset value.

On the regulatory side, the situation in the low carbon building market is turning from passive encouragement to active enforcement. 2025 is the turning point for France with a ban on the rental of the lowest-performing energy buildings, which is pushing landlords to either renovate or divest their properties. Vietnam has introduced mandatory GHG inventory plans for large construction projects and the US Inflation Reduction Act has succeeded in triggering a manufacturing boom for low carbon materials. However, there is a dangerous gap because 50% of new construction in the world is still happening in countries without mandatory energy codes. This regulatory vacuum is the single biggest risk for the sector, but it will also signal where policy advocacy and international aid will likely be targeting in the years ahead.

Commercial application represents a strong 51.22% market share of the low carbon building market, with multinational tenants simply refusing to lease non-compliant spaces being a key factor. JLL's 2025 outlook report predicts there will be an acute supply shortage for zero-carbon offices in locations such as London and New York, where developers will be forced to upgrade or lose clients. BlackRock has changed financial landscape as it revised its guidelines to distribute US$ 150 billion to funds assessing energy transition risks. Amazon is setting the bar for construction worldwide with its net-zero certified headquarters expansion in Arlington and Nashville. Google is making the same steps, pledging to geothermal heating systems for its new campuses to sever all ties with natural gas.

• Tenants are signing green leases that legally require that data on energy consumption be shared.
• Big-box retailers are tricking up stores with automated energy management systems to save on costs.
• Landlords are scrambling to retrofit heating, ventilation and air conditioning systems to prevent devaluation of their assets by new regulations on the horizon.

Financial incentives are also helping to widen the gap between green and brown assets in the Low carbon building market. CBRE data confirms that prime offices with low carbon certifications are commanding large rental premiums over older stock. Empire State Realty Trust has taken the proactive step to procure wind power to offset 100% of its electricity load of its commercial portfolio. IoT systems are taken up by hotel chains to monitor emissions per guest night to cater to the eco-conscious travellers. Data center operators are turning to green steel to reduce scope 3 emissions. The "Green Tipping Point" report suggests that the upcoming lease expiries are colliding with 2030 targets, they need to rapidly retrofit.

Advancements In Mass Timber and Green Steel Redefine The Structure

Structural components account for the most significant market share at 42% for the low carbon building market because engineers are finally replacing carbon-heavy concrete with lighter and smarter alternatives. The International Building Code updates for 2024 and 2025 do not impose as many constraints on mass timber structures and pave the way for 18-story wooden high-rises in the US. Mercer Mass Timber has seized on this with many cross-laminated timber facilities finished to capitalize on this growing demand. Nucor recently introduced "Aeos" a net zero, steel product designed for heavy structural beams. Blue Planet Systems is successfully scaling its synthetic limestone aggregate produced from sequestered CO2 for structural concrete applications to make buildings carbon sinks.

• Hybrid timber-steel systems are minimizing the foundation needs and overall weight of the building.
• Prefabricated structural panels are reducing on-site waste and transportation related emissions.
• Carbon-cured concrete blocks are becoming standard specifications for Municipal infrastructure projects.

Heavy industry is changing at a fast pace to meet the structural needs of the Low carbon building market. ArcelorMittal is supplying its XCarb recycled steel to major infrastructure locations, such as foundations for renewable energy projects. Modvion has demonstrated the viability of wood in heavy industry by building towers for wind turbines made of wood. Third Party Certificate- Brimstone has received a critical third party certification that their rock based ordinary portland cement meets the structural standards as required by the American standards for materials. (ASTM). CEMEX has introduced Vertua low carbon concrete for highway pillars. The "Heartwood" workforce housing project in Seattle shows that the concept of mass timber can work on a residential scale. Meanwhile, the "Hybrit" technology of Swedish steel maker SSAB is bringing fossil-free steel for building frames.

Regional Analysis 

Strict European Climate Policies & Industrial Retrofits Power Regional Market Leadership

Europe currently leads the low carbon building market with a massive market share of 39.17% of the market, mainly because the region has moved from voluntary targets to legally binding targets. In 2024 the EU aggressively passed the revised Energy Performance of Buildings Directive that now legally mandates the zero-emission of all new public structures by 2028. Such pressure through policy induced Heidelberg Materials to complete its Brevik plant in Norway mechanically, the cement industry's first industrial-scale carbon capture facility. Sweden is also pushing boundaries with SSAB confirming the conversion of its Lulea mill in a massive green steel project with a value of US$ 4.8 billion. At the same time, the UK Net Zero Carbon Buildings Standard started to launch its pilot in September 2024, finally providing developers with clear technical limits for embodied carbon.

Corporations are responding quickly to these regulatory signals to ensure that they have their place in the Low carbon building market. Saint-Gobain recently closed its acquisition of Fosroc in order to solidify its position in the market of sustainable construction chemicals on the continent. ArcelorMittal has already broken ground on a 1.1 million tons Electric Arc Furnace in Gijon, Spain, so there is a guaranteed supply of green steel rails. Holcim has completely exploited its ECOPact low-carbon concrete in its European fleet to satisfy infrastructure needs. Additionally, Parmaco and SSAB signed a ground-breaking deal for the world's first fossil-free steel concept building in Finland it by 2025. These concerted drives are the reason why Europe is at the forefront of the Low carbon building market.

North America Speeds Up Decarbonization With Record Federal Funding, Material Shifts

North America in the global low carbon building market has made an aggressive shift towards low-carbon technologies in 2024 with large federal incentives and a real shift in consumer heating preferences. The region witnessed the shipments of United States heat pumps on the order of 4.1 million in 2024, continuing a critical trend where these electric appliances outsold gas furnaces by a margin of 32%. Federal support was a huge kickstarter with the Department of Energy recently awarding US$ 6 billion for industrial decarbonization projects in March 2024 with specific grants of US$ 500 million for Heidelberg Materials carbon capture.

Innovation in materials also got unprecedented financial support, as seen in Sublime Systems winning a US$ 87 million federal award to scale fossil fuel-free cement. At the same time, Brimstone Energy was chosen for a US$ 189 million grant to produce carbon negative ordinary Portland cement. Market adoption of clean technologies was also seen in the regional low carbon building market with homeowners using Inflation Reduction Act tax credits for 453,000 heat pump installations in 2024 alone. Corporate maneuvering reflected this value shift, with Holcim announcing a spin-off of its North American business with an envisaged valuation of more than US$ 30 billion. Major consolidations, such as the US$ 3.9 billion acquisition of Masonite by Owens Corning, are a further indication that the market is reorganizing around sustainable building envelopes and energy-efficient retrofits.
