Indoor environmental quality (IEQ) generally refers to the quality of a building’s environment with respect to the health of its occupants. RHP specializes in IEQ testing in commercial buildings, industrial facilities and residential homes.

Indoor environments have high variability from building to building and may present complex issues, including thermal conditions, air quality, lighting, dampness & even personal hygiene. Maintaining the health of a building’s indoor environment is critical to maintaining the health of its occupants. A healthy indoor environment will support elevated focus, reduced stress and injuries and allow occupants to conduct their business. Increased IEQ also supports the relative value of a building and reduces the risk and liability for building ownership and/or management.


Indoor environments have high variability from building to building and may present complex issues. Some of the more common sources include: airborne chemicals; airborne particulates; combustion byproducts; dampness & mold growth; ergonomics (lighting & noise); poor ventilation; temperature & relative humidity; tobacco & vaping smoke; and Volatile Organic Compounds (VOCs).

Inspections and Testing

RHP’s approach to projects varies depending on the nature of the problem. Each project typically requires an interviewing process to gather essential information followed by a walk-through of the space to understand the client’s concerns. Once an understanding of the project objectives is established, RHP is able to conduct the investigation.

RHP utilizes state-of-the-art monitoring and sampling equipment in order to provide the most accurate and defensible data. If desired, RHP can provide a written representation or oral summary on the details of our findings and recommendations.

RHP’s expert team of certified industrial hygienists, public health scientists, and certified safety professionals carry decades of experience working closely with clients and regulatory agencies in identification, analysis, and management of existing and potential health concerns associated with air quality issues.
