Building envelope trade-offs offer a flexible path to energy code compliance, but they require careful analysis and documentation, especially in high-rise projects.
If you need help navigating trade-off calculations, E3 Power is here for you. We use COMcheck™ to calculate building envelope trade-offs in high-rise projects, making code compliance simple and stress-free.
Here’s a closer look at what COMcheck is and how it helps with building envelope trade-offs in Colorado.
What Is COMcheck?
COMcheck is a software tool that was developed by the Department of Energy to help architects, builders, and designers verify code compliance in high-rise buildings. It simplifies building envelope trade-offs with automated calculations that are checked against IECC and ASHRAE 90.1 standards.
Can you DIY a COMcheck Report?
COMcheck is a free software program that anyone can use. But the learning curve is steep. If you don’t want to waste time and money on software training for your team, it’s best to hire a professional like e3 Power for COMcheck reports.
Why Use Trade-Offs in Your Design?
Building envelope trade-offs allow you to compensate for certain elements of your design that don’t meet energy code by going above-code in another area.
For example, if your building has a high window-to-wall ratio, you could increase the R-value of insulation in walls and ceilings to make up for the added heat loss and heat gain attributed to the windows.
The benefits here are significant:
- Reduce Project Costs – Utilizing trade-offs strategically can lower overall project costs by allowing you to meet code through the most cost-effective combination of measures rather than upgrading every component to prescriptive minimums.
- Increase Design Flexibility – Trade-offs give you more design freedom, so you can prioritize aesthetics, daylighting, or layout while ensuring energy code compliance.
- Streamline Code Compliance – When used correctly, trade-offs can simplify the path to compliance by balancing performance across the entire building envelope rather than forcing strict pass/fail requirements for each individual element.
How COMcheck Helps with Building Envelope Trade-Offs
Simplifies Complex Trade-Off Calculations
Calculating the overall UA for a building envelope gets tricky fast when trade-offs are involved, especially if multiple are needed. COMcheck automates the trade-off calculations, speeding things up and ensuring accuracy.
Ensures Accurate Calculations
It’s easy to make mistakes when calculating trade-offs without software. By using COMcheck, you know your calculations are 100% accurate, so there are no surprises when you submit your permit application to the Department of Buildings.
Verifies Code Compliance with Comprehensive Reports
When you use COMcheck for building envelope trade-off calculations, you receive an official compliance report that can be submitted directly with your building permit application. Because COMcheck is a widely recognized and trusted tool, these reports help streamline plan review and give code officials confidence that the project meets energy code requirements.
Have Questions? e3 Power Is Here for You
Building envelope trade-offs can be a powerful tool for achieving energy code compliance, but only when they’re calculated correctly and documented clearly. In high-rise projects, even small errors or assumptions can lead to plan review comments, delays, or costly revisions.
e3 Power helps project teams avoid those risks by providing accurate, defensible COMcheck™ reports tailored to Colorado energy code requirements. Whether you’re in early design or preparing for permit submission, we can support your project with clear analysis and reliable documentation.
