E&B staff is trained in obtaining and recording critical conditions and events using digital video and still photography so that the images are relevant, admissible and convincing.

E&B has the capacity to store and cross reference thousands of digital images so that they can be organized according to multiple criteria, and can be recalled nearly instantly.

Using a combination of real-time Type 1 and Type 2 survey meters, and Type 2 Datalogging Meters, sound sources can be profiled, monitored and graphed as to frequency, level and duration.

As part of exterior envelope and environmental investigations, E&B uses digital and analog devices to detect relative levels of moisture in surfaces including wood, plaster and concrete. Portable weather monitors provide ambient readings of temperature, humidity, air velocity and barometric pressure.

E&B utilizes a camera that observes the infrared spectrum of objects and surfaces, versus the visible light spectrum, and which displays the surface temperature of the object in an image with color gradations. This can be used to infer the presence of moisture in the material, analyze cold or hot air intrusion, and/or performance issues with heating and cooling systems.

Pressure differentials in building compartments, walls, and from space-to-space indicate a flow direction and volume. Determining the physical factors of the air (temperature and humidity) and the direction and volume of the air movement can assist in determine building energy performance (air leakage), dew point locations (for potential moisture concerns), HVAC equipment performance (flow, volume, temperature and humidity), and exhaust system performance.

Utilizing a PID with a 1 PPB (part per billion) detection limit can trace back sources of chemicals and odors. Floor and deck sealants, applied two-part compounds, and solvent residue can be traced and mapped, detecting improperly mixed, cured or applied building materials (which contain VOC’ s as a component).

Combustion sources in buildings can be a source of carbon monoxide exposure, if not installed and operated correctly. Using a real-time carbon monoxide monitor, sources can be tracked, and, exposures can be determined during the operating cycle. The system can then be evaluated for isolation, fire separation, supply air / exhaust requirements.

Using a non-toxic gas not found in nature, in combination with portable hand-held detectors, the route of odors, fugitive air sources and combustion sources can be traced through a building. If a toxic gas (such as carbon monoxide) is suspected from a source to reach a receptor location, a non-toxic gas can be used at the presumed point of origin of the toxic gas to confirm or deny the route through the building.

Cigarette smoke, metallic fumes and fine corrosion products can be traced to their source using our real-time ultra-fine particle counter (UFP). Breaches in building seals, firestopping, and ductwork can be detected by comparing UFP concentrations in the ambient air versus at the seal locations. Plenums and interstitial wall spaces can be checked and tracked back to breaches in sealed separations.
