Title: Emishaw D Iffa: Innovator in Building Leakage Detection
Introduction
Emishaw D Iffa is a notable inventor based in Knoxville, TN (US). He has made significant contributions to the field of building leakage detection through his innovative patent. His work focuses on non-invasive techniques that enhance the efficiency of identifying leaks in building structures.
Latest Patents
Emishaw D Iffa holds a patent for a "Building leakage detector using reference-free background oriented schlieren photography." This invention presents a non-invasive method to measure exfiltration and infiltration in buildings. The system employs RFN-BOS photography, which allows for the visualization of leakage through a building envelope when the background has sufficient texture and the temperature difference between the leakage and ambient air is adequate. Notably, leakage can be detected with a temperature difference as low as 12° C to 15° C through CMU and brick claddings. The detection limit can be reduced to 5° C, making the RFN-BOS technique applicable across all climate zones. If the cladding lacks sufficient texture, the system utilizes a projection system to project a high-contrast image pattern on the cladding surface. The invention also prioritizes sealing of leaks based on their corresponding leak-ranking parameters.
