In many cases, blower door tests are required by Colorado energy code. If you’re planning a new construction project, you will likely need one.
But even when it’s not mandatory, testing gives you valuable insights into your building’s energy efficiency and helps identify opportunities for improvement.
In this guide, we’ll cover when blower door testing is required in Colorado, when it’s recommended, and the key signs your building may need one.
Why Invest in a Blower Door Test?
A blower door test measures the total amount of air leakage in a building. This data reveals how airtight your building is and helps guide targeted air sealing improvements.
For building owners and managers, that leads to:
- Lower energy use and operating costs
- Improved occupant health and comfort
- Smaller carbon footprint
- Progress toward sustainability goals
For many commercial facilities, reducing uncontrolled air transfer is the most cost-effective way to improve energy efficiency.
When a Blower Door Test Is Required in Colorado
Most Colorado jurisdictions have adopted the 2021 International Energy Conservation Code (IECC), which requires blower door testing for new residential and commercial construction. Some jurisdictions also require a blower door test for additions and major renovations.
If your test is required by code, your builder cannot legally perform it. It must be completed by a licensed third-party. At e3 Power, we’re certified to perform blower door testing throughout Colorado and can help ensure your project meets energy code requirements. Contact us today to schedule a test.
When a Blower Door Test Is Recommended
Even if testing isn’t required by code, it’s still a smart investment. We recommend scheduling a blower door test if:
- Energy costs are too high – A blower door test will guide improvements that save energy and reduce operating costs.
- Comfort is a serious issue – A blower door test will determine whether air leakage is causing problems like drafts that impact occupant comfort and air quality.
- You’re buying a new building – A blower door test will help you understand the energy efficiency of a building before you buy it.
- You’re making insulation improvements – A blower door test will give you a baseline of total air leakage before an insulation and air sealing project, so you can verify whether the work was effective.
- You’re pursuing sustainability or decarbonization goals – Air leakage is a significant contributor to energy waste in commercial buildings. Testing is the first step toward making improvements that reduce your carbon footprint.
Signs Your Building Needs a Blower Door Test
Not sure if your building needs an air leakage test? Here are some signs that you could benefit from one:
- High Energy Costs – Inexplicably expensive heating and air conditioning costs are often due to air leaks.
- Poor Indoor Air Quality – Air leaks let allergens like pollen into your building. They also let moisture in, which can lead to mold.
- Drafts & Comfort Issues – Cold drafts and inconsistent temperatures indoors are often caused by a combination of air leaks and poor insulation.
