Research output: NRELSubcontract Report


In fiscal year 2013, Pacific Northwest National Laboratory (PNNL), Florida Solar Energy Center (FSEC), and Florida Home Energy and Resources Organization (Florida HERO) began a collaborative effort to evaluate the impact of ventilation rate on interior comfort conditions, space-conditioning energy use, and indoor air contaminant concentrations. Relevant parameters were measured in 10 homes in Gainesville, Florida, along with corresponding outdoor conditions, to characterize the impact of differing ventilation rates. This report provides information about the data collection method and results from more than 1 year of data collection during a period from summer 2013 through summer 2014. Indoor air quality was sampled in three discrete periods with the first occurring in August/September 2013, the second occurring in March/April 2014, and the third occurring in August 2014.
