At Alpha Weatherization, we help homeowners, property managers, and businesses throughout Chicagoland understand how well their buildings truly perform. Our building performance testing services provide a data-driven look at energy efficiency, comfort, and indoor air quality—identifying the issues that waste energy, increase costs, or reduce comfort. By combining advanced diagnostic tools with years of construction expertise, we deliver precise insights that guide smarter upgrades and ensure your building operates at its best.
Every structure, whether a single-family home or a large commercial space, functions as a system. When one component underperforms—insulation, ductwork, air sealing, or ventilation—it affects the entire building. Alpha Weatherization’s performance testing helps uncover these inefficiencies, providing a clear path to improvements that make your space more comfortable, more efficient, and more sustainable.
What Building Performance Testing Involves
Building performance testing measures how effectively your property retains conditioned air, manages airflow, and maintains consistent comfort levels. Our testing services are customized to your specific property and goals, and may include:
- Blower Door Testing: Identifies air leaks in the building envelope by depressurizing the home and locating areas where outside air infiltrates.
- Duct Leakage Testing: Measures how much air escapes from ductwork, revealing inefficiencies in heating and cooling delivery systems.
- Infrared Thermal Imaging: Uses advanced cameras to detect heat loss, insulation gaps, and air leakage points hidden within walls and ceilings.
- Combustion Safety Testing: Ensures gas appliances are venting properly and that indoor air quality remains safe and healthy.
- Ventilation and Airflow Testing: Verifies that fresh air systems meet performance and comfort standards.
Together, these tests provide a detailed picture of how your building performs and where improvements can make the biggest impact.
Our Proven Testing Process
Alpha Weatherization follows a structured, transparent process to ensure accurate results and actionable insights.
1. Consultation and Inspection
We begin with an on-site visit to understand your concerns—whether high utility bills, uneven temperatures, or indoor air quality issues. Our team evaluates the building’s construction, HVAC systems, and insulation levels to establish a baseline before testing.
2. Diagnostic Testing and Data Collection
Using specialized equipment, we conduct a series of controlled tests to measure air tightness, duct efficiency, and overall energy performance. We record detailed data on airflow, pressure differences, and temperature variations throughout the building.
3. Analysis and Reporting
After testing, we analyze the results to identify performance gaps, such as excessive air leakage, inadequate insulation, or ventilation imbalances. We then compile a clear, easy-to-understand report outlining what we found and how to fix it.
4. Recommendations and Next Steps
Based on your test results, our experts recommend targeted improvements that offer the greatest return on investment—often through air sealing, insulation upgrades, or mechanical system adjustments. If you choose, our team can also complete the recommended work to ensure verified results and compliance with local energy standards.
