How to prepare for a ResCheck inspection

by admin

If you are building a new residential structure or making substantial renovations to an existing one, chances are you will need to undergo a ResCheck inspection. ResCheck is a software tool developed by the Department of Energy to ensure that new homes and additions meet specific energy efficiency requirements outlined in the International Energy Conservation Code (IECC).

One of the most critical components of a ResCheck inspection is blower door testing. This test measures the airtightness of a building envelope and helps identify areas where air leakage may be occurring. Proper preparation for a ResCheck inspection, including blower door testing, can help ensure that your building passes inspection and meets energy efficiency standards.

Here are some key steps to help you prepare for a ResCheck inspection and blower door testing:

1. Familiarize yourself with the ResCheck requirements: Before scheduling a ResCheck inspection, it is essential to understand the specific energy efficiency requirements that your building must meet. The ResCheck software will help you calculate the required insulation levels, window U-factors, and air leakage rates based on the IECC standards.

2. Ensure proper insulation installation: Proper insulation is essential for achieving energy efficiency in a building. Before the ResCheck inspection, make sure that all insulation materials are installed correctly and meet the minimum R-values required by the IECC.

3. Seal all potential air leaks: Air leakage can significantly impact the energy efficiency of a building. Before the blower door testing, thoroughly inspect the building envelope for any gaps, cracks, or holes where air may be escaping. Seal these areas with weather-stripping, caulking, or spray foam insulation to improve airtightness.

4. Schedule a blower door test: A blower door test is a crucial part of the ResCheck inspection process. This test measures the airtightness of a building by depressurizing it and quantifying the amount of air leakage. Contact a certified energy auditor or building performance professional to schedule a blower door test before the ResCheck inspection.

5. Prepare for the blower door test: Before the blower door testing, make sure all windows and doors are closed, and all combustion appliances are turned off. The auditor will install a blower door system in an exterior door to measure airflow and identify areas of air leakage. Be prepared to provide access to all areas of the building during the test.

By following these steps and adequately preparing for a ResCheck inspection and blower door testing, you can ensure that your building meets energy efficiency standards and passes inspection. Remember that energy-efficient buildings not only reduce utility costs but also contribute to a healthier and more comfortable indoor environment.
