Errors resulting from the use of single-zone ventilation models on multizone buildings: Implications for energy conservation and indoor air quality studies
Errors resulting from treating a house as an enclosure surrounding a single, well-mixed volume of air are explored in detail for a ranch house with a basement. A fairly typical ventilation pattern is assumed, and three quantities--the air exchange rate, the indoor pollutant concentration from a given emission, and the energy required to heat infiltrating air--are calculated and compared using both the one-and two-zone models for this house. In general, the errors were around 10% to 20% if the basement was included in the one-zone models and 30% to 40% if the basement was neglected. Other factors that effect the magnitude of these errors include the length of a pollutant release, the outdoor temperature, and the air exchange rate measurement protocol, as well as the particular ventilation characteristics of the house.
