CONTAM To EnergyPlus Infiltration Features of the CONTAM Results Export Tool



Brian J. Polidoro, Lisa C. Ng, William S. Dols, Steven J. Emmerich, Andrew K. Persily


As building envelope performance and HVAC equipment efficiencies continue to be improved to reduce building energy use, a greater percentage of the total energy loss of a building can occur through envelope leakage. Although the energy impacts of unintended infiltration on a building’s energy use can be significant, current energy simulations and building designs generally do not accurately account for envelope infiltration and the impacts of improved airtightness. Infiltration has long been recognized as a key component of heating and cooling loads. Various methods exist to account for infiltration in load calculations and more detailed energy analysis. However, the inputs for these methods are not readily available. Thus, a tool has been developed to incorporate infiltration rates from a multizone model, CONTAM, into a building simulation model, EnergyPlus. This document describes how to use the CONTAM to EnergyPlus Infiltration Tool available at http://url-to-be-determined.
