Control Humidity Levels Since silverfish are attracted to moist, humid environments, reducing your home's humidity level to below 60% can help eliminate them. Consider using a dehumidifier in high ...
Mold growth can be inhibited by keeping surfaces at conditions that are further from condensation, with relative humidity levels below 75%. This usually translates to a relative humidity of indoor air below 60%, in agreement with the guidelines for thermal comfort that recommend a relative humidity between 40 and 60 %.
Midea's popular dehumidifier covers up to 1,500 square feet, making it great for an entire floor of your home or your basement. This dehumidifier is Energy-Star certified, so it won't jack up your ...
T07 Humidity Control, control of humidity receives 1 point by having mechanical system that can maintain relative humidity 30% to 60% at all times or submitting document that modeled relative humidity levels in space from 30% to 60% for at least 98% of all business hours or by meeting thermal comfort monitoring (T06) with relative humidity ...
For humidity ratios above 0.012 kg H 2 O/kg dry air (0.012 lb H 2 O/lb dry air), or for metabolic rates up to 2.0 met, the analytical model must be used to determine thermal comfort sensation. Also based on the PMV model, this method uses tools such as the ASHRAE Thermal Comfort Tool or the online CBE Thermal Comfort Tool for ASHRAE 55 [ 2 ] to ...
