The Trifecta Approach →
Our Trifecta Approach represents the foundation of every service we deliver — a deliberate process that connects diagnostic precision, targeted improvement, and measurable verification. It begins with testing: gathering real building data through blower door analysis, thermal imaging, and pressure mapping to locate where energy and comfort are being lost. Next comes optimization — sealing attics, ducts, and pressure boundaries to bring the system into balance. Finally, we verify performance, confirming that the improvements deliver measurable comfort, code compliance, and return on investment. By combining science, craftsmanship, and community purpose, Project Probono has made the Trifecta Approach the standard for sustainable home performance throughout the Lehigh Valley since 1997.
