Evaluate Building Envelope for Energy Efficiency
|
Conversion Technology, Inc. (CTI) conducts various tests to evaluate the building envelope for energy efficiency. The methods used are:
- Test Method for Determining Air Leakage Rate
and
- Standard Test Methods for Determining Air Tightness of Buildings
Field tests are conducted on days of low-wind pressure conditions to minimize error associated with non-laboratory conditions. Each multi-zone building is divided into numerous and convenient smaller single-zones by opening or sealing interior doors/openings or by inducing equal pressures in adjacent zones. CTI, where practical, calibrates facility makeup air fan(s) for testing the entire facility as a single zone.
Measurements of pressure differences and airflows are used to determine air tightness and other leakage characteristics of the buildings envelope. Testing is recommended to occur during minimal building traffic to optimize the integrity of the results.
- Thermal leakage is also performed using digital thermal camera technology to identify “hot”/”cold” spots in building envelope. Special attention is focused on envelope piping penetrations, weather stripping, electrical conduit and facility egress and glazing openings. Camera thermal accuracy is maintained down to 0.1 °C or better.
