Invention Reference Number

This invention adapts background oriented schlieren (BOS) imaging to directly visualize building leakage in a fast and easy manner. Recent advancements have implemented this technology within a smartphone, utilizing the existing camera and a custom application to provide real-time visualization of leaks. This innovative approach offers a practical and accessible solution for detecting leakage in buildings.
Description
This invention addresses the challenge of locating air leakage sites in buildings, which is commonly performed using a blower door to create a large pressure differential along with infrared imaging, smoke pencils, theatrical smoke, or manually feeling around penetrations for drafts. These conventional techniques can be time-consuming, disruptive to occupants, and often require significant expertise. The invention adapts background oriented schlieren (BOS) imaging technology to visualize building leakage effectively, offering a faster and more streamlined approach. Additionally, this technology has been integrated into a smartphone application that utilizes the existing camera to provide visualization of leaks.
Benefits
- No need for large pressure differences: Eliminates the necessity for blower door setups by functioning effectively with or without high pressure differentials.
- Utilization of existing equipment: Can leverage existing building systems, such as exhaust fans or HVAC units, to create a modest pressure difference.
- User-friendly technology: Requires no specialized expertise, allowing anyone to use the system for direct visualization of air leakage.
Applications and Industries
- Building and construction industry: Building energy audits and inspections to identify and visualize air leakage in residential and commercial structures.
- HVAC sectors: Improvement of energy efficiency and indoor air quality, enhancing overall building comfort.
