Building diagnostics is a practical tool that can be used to identify the source of the problem and to identify the steps to be taken and recommend corrective action to the owner.
The diagnostic procedures may be used during any construction phase (planning, design, execution, and operational), and the missions involve:
- Assess the planned performance of buildings and structures during the design analysis (e.g., HVAC, envelope, energy conservation, etc.).
- Test the impact of environmental exposures and system performance on human response and occupant performance outcomes.
- Investigate mold impact on building materials and furnishings during construction and operation of buildings.
- Investigate complaints from occupants about discomfort, symptoms and diseases caused by chemical and microbiological contaminants.
Building diagnostics is a convenient method for detecting and isolating mold/moisture issues that are mostly related to envelope problems e.g. leaks from roofs, walls, foundations, windows and doors), minor and catastrophic pipe failures (e.g. plumbing and appliance leaks), and sewage backups and floods. Excessive duct leakage can cause pressure imbalances through the envelope, which can also cause problems with moisture control, including mold formation.
