  Five Principles of Mold Cleanup

  There are five general principles of cleaning up - or remediating - mold.
• Relative Humidity

  Does Your Home Have High Relative Humidity?

  Humidity refers to the water-vapor content of air. Because there is always some moisture in the air, it can be difficult to think of humidity as a pollutant. Yet, if your indoor air contains high levels of water vapor, it can cause major problems.
• Chemical Sensitivity

  Case Study: Building a Home for the Chemically Sensitive

  In early 2007 Kevin and Kathy Christopherson set about building a home in Hanover, Wisconsin. This was no ordinary new home construction, though. Since Kathy has an acute chemical sensitivity, special precautions were necessary – precautions that presented some particularly challenging construction issues.
• Ventilation

  What are HRVs/ERVs?

  Heat recovery ventilators (HRV) and energy recovery ventilators (ERV) are air exchange systems that help to enhance indoor air quality and minimize heating costs.
• HRV

  Heat Recovery Ventilators - Getting Technical

  The majority of the balanced ventilation systems on the market are heat recovery ventilators (HRVs). Most HRVs consist of an insulated cabinet, a heat-recovery core, two fans, some ductwork, and a control. But not all HRVs are created equal.
