States that adopt the updated 2024 International Energy Conservation Code could see building costs for a typical single-family home go up by $14,000, the Department of Energy (DOE) warned on June 26.
The International Energy Conservation Code (IECC) is a model code developed by the Washington-based International Code Council (ICC) for setting minimum energy efficiency requirements for commercial and residential buildings.
While the ICC doesn’t mandate its code, states and local jurisdictions can choose to mandate the code in their building standards. The IECC is the most adopted across the United States as it is recognized in federal law as the national model energy code for low-rise residential buildings.
The DOE takes part in the ICC’s consensus process to update energy efficiency provisions of the IECC. The code is revised once every three years.
Regarding the latest IECC codes published in 2024, the DOE has determined that adoption of the code “would increase residential construction costs by more than $9.2 billion annually compared to the 2006 code levels, adding more than $127 billion in cumulative costs nationwide.”
The IECC model regulation forces “American families to pay thousands of dollars more upfront for a new home, while projected energy savings may take decades to materialize. In most states, estimated payback periods exceed 10 years, with some exceeding 20 years—locking American families into decades-long repayment timeframes and restricting consumer choice.”
According to the National Association of Home Builders, the 2024 IECC contains several provisions related to energy efficiency, including heat or energy recovery ventilation systems; installation of energy-efficient appliances such as refrigerators, dishwashers, and clothes washers; and the deployment of renewable energy resources on building sites.
In March 2024, when the 2024 IECC codes were approved by the ICC’s Board of Directors, the ICC said that the new codes were anticipated to improve energy efficiency for commercial buildings by roughly 10 percent, and for residential buildings by around 6.5 percent.
On Feb. 15 this year, the DOE sent a letter to the ICC, raising “serious concerns” about the trajectory of the IECC.
The purpose of IECC is to provide model building codes that can be adopted to provide energy efficiency gains for communities. However, in recent years, IECC has expanded its scope to focus on areas such as energy generation infrastructure requirements and greenhouse gas emissions. This shift risks undermining existing DOE objectives, the letter said.
The department’s priorities for building energy codes involve ensuring affordability for American households and businesses, and safeguarding consumer choice to opt for their preferred appliances and equipment.
The DOE urged the ICC to return its codes to its traditional focus on building energy efficiency that would provide both “clear cost savings and beneficial efficiency advances” to consumers.
In its recent statement, the DOE said it encouraged the ICC to omit requirements related to onsite energy generation and greenhouse gas avoidance, which raise construction costs.
“This analysis shows how unnecessary regulations and ineffective building codes have drastically increased housing costs with little to no benefit for homeowners or communities,” Assistant Secretary of Energy Audrey Robertson said.
“Standard-setting bodies should take note: we prioritize the American homeowner and will not allow erroneous building requirements to push homeownership out of reach.”
The Epoch Times reached out to ICC for comment but did not receive a response by publication time.
Ensuring Housing Affordability
The DOE said in its recent statement that it would continue implementing President Donald Trump’s March 13 executive order titled “Removing Regulatory Barriers to Affordable Home Construction.”
In the order, Trump wrote that unnecessary regulatory barriers and “onerous mandates” have delayed construction and driven up the cost of new homes, making housing less affordable for Americans.
One of the provisions in the order directed the Secretaries of Energy, Housing and Urban Development (HUD), and Agriculture to take “appropriate action to reform and, where appropriate, eliminate unduly burdensome or costly energy-efficiency, water-use, or alternative-energy requirements regarding housing.”
This shall include reviewing and revising residential building energy codes, energy efficiency standards for certain new construction, and energy conservation standards for manufactured housing.
In a March 13 statement, HUD said that regulatory costs make up almost $94,000 in the final price of a new single-family home, with green energy mandates in building codes alone raising construction costs by $30,000.
As such, cutting red tape, including “onerous” energy and water requirements and “woke” green building codes, will boost housing stock and bring down the cost of newly built homes, the department said.
In April, HUD and the Department of Agriculture rescinded a policy related to energy standards, which HUD said would have pushed home construction costs by $20,000 to $31,000.
