A Statistical Approach for DeltaQ Modeling Concerning Building Envelope and HVAC Duct Leakage Behavior Prediction

March 22, 2006 - 12:00pm
Bldg. 90

The DeltaQ duct leakage test method has been created as an improvement to existing Duct Pressurization tests. It focuses on measuring the Building's Envelope Air and the HVAC duct air leakages to outside at operating conditions, needed for energy lost calculations or for infiltration impacts.  The laboratory measurement data used for DeltaQ estimations are applied in the balance equations in dimensioned mode and this involves uncertainty and error distribution in calculation process. This study is targeted to using dimensionless data approach, applicable as in online data calculations in an automated experiment method as well as in a statistical data prediction approach. Derived statistical model can be used in the developed here new modified balance equations for a DeltaQ test application. If time permits, two additional topics will be discussed:  "Global Criteria Used for the Estimation of Heat Insulation Efficiency", and "Solar Screen made from Phase-Exchange Material - Radiative Heat Exchange Model".
