Differentiating Each State’s Unique Building Energy Codes 

Differentiating Building Energy Codes US

May 8th, 2023

Building Energy Codes play a crucial role in regulating the energy efficiency of new and renovated buildings, reducing energy use and operational carbon emissions over the building's life cycle. The United States has adopted rigorous energy standards across states and territories to reduce energy consumption and combat climate change. 

Energy codes in the United States have become increasingly stringent over the last few years, with many states adopting newer versions of the code. This progressive tightening of energy codes is supported by federal policies, recognizing that robust regulation will contribute to the country's efforts in achieving its national sustainability targets. 

Additionally, some states comply with their own energy code that they have developed. The selected code loads all the prescriptive inputs based on the codes, such as envelope and lighting. Other inputs not specified by energy codes are based on industry-standard practice, ASHRAE (American Society of Heating, Refrigerating, and Air Conditioning Engineers) User's Manual, and the PNNL Prototypes

In cove.tool, the project's building energy code is automatically selected based on building location, with each state in the US adopting a specific version of ASHRAE 90.1 or IECC (International Energy Conservation Code) standards.  

By utilizing cove.tool, building professionals can ensure that their projects are compliant with the latest energy codes, leading to more sustainable and efficient buildings.
