Investigation Of The Effectiveness And Failure Rates Of Whole-House Mechanical Ventilation Systems In Florida, Florida Solar Energy Center, Jeffrey Sonne
Investigation Of The Effectiveness And Failure Rates Of Whole-House Mechanical Ventilation Systems In Florida, Florida Solar Energy Center, Jeffrey Sonne
FSEC Energy Research Center®
This report presents the results of a field investigation of the effectiveness and failure rates of whole-house mechanical ventilation systems installed in Florida homes over the last 15 years. The report includes homeowner survey and ventilation system testing results and code modification recommendations based on study findings.

Energy recovery ventilator (ERV) or Heat Recovery Ventilator (HRV) devices recover energy from building's exhaust air to precondition outdoor air. Energy savings of ERV/HRV devices were determined for various commercial buildings in Florida climate using whole building energy simulation tool. The annual HVAC energy percent savings due to ERV/HRV device were calculated from HVAC energy use of a standard reference building without and with ERV/HRV device using EnergyPlus. The annual HVAC energy savings potential (ERV Credits) will be used for code compliance calculation when a compliance software does not have ERV modeling capability. The ERV/HRV credits were reported by building …

Most studies on the transmission of infectious airborne disease have focused on patient room air changes per hour (ACH) and how ACH provides pathogen dilution and removal. The logical but mostly unproven premise is that greater air change rates reduce the concentration of infectious particles and thus, the probability of airborne disease transmission. Recently, a growing body of research suggests pathways between pathogenic source (patient) and control (exhaust) may be the dominant environmental factor. While increases in airborne disease transmission have been associated with ventilation rates below 2 ACH, comparatively less data are available to quantify the benefits of higher …
