ASTM E3158 Testing in Oregon

ASTM E3158-18 Air Leakage Testing

ASTM E3158-18 is the standard test method for measuring the air leakage rate of large or multizone buildings. This method involves pressurizing and depressurizing a building to quantify its air leakage, providing valuable data on the building envelope’s performance. In Oregon, conducting ASTM E3158-18 testing is essential. It helps identify unintended air leakage pathways, enabling targeted improvements that enhance thermal performance. This test reduces energy consumption and ensure compliance with local building codes. By adhering to this standard, building professionals can contribute to the development of sustainable and comfortable structures.

What to Expect with ASTM E3158-18 Testing

When undergoing ASTM E3158-18 testing, expect a thorough evaluation of your building’s air leakage performance. Technicians begin by sealing intentional openings and setting up specialized blower-door equipment to pressurize and depressurize the building. Throughout the test, airflow rates are carefully measured and recorded, enabling precise identification of leakage points and overall envelope performance. Upon completion, you’ll receive a detailed report clearly outlining the measured air leakage rates, highlighting compliance with Oregon’s energy-efficiency standards, and offering practical recommendations for improving the building’s airtightness and energy performance.
