INTEGRATING WHOLE BUILDING AIR LEAKAGE TEST DATA INTO ENERGYPLUS INFILTRATION MODELS
Our presentation for the 2014 ASHRAE/IBPSA
conference, “Simulating Air Leakage in a Whole
Building Energy Model – An Existing Building Study”,
summarized our effort to model a building before and
after a window replacement project. We obtained very
good model correlation to actual heating loads using data
from whole building air infiltration tests integrated with
an EnergyPlus Airflow Network object. The following
reviews our process and results.
ASTM International 2010 Standard Test Method for Determining Air Leakage Rate By Fan Pressurization, Para 9.5, Eq 3.
American Society of Heating Refrigeration and AirConditioning Engineers Handbook Fundamentals 2013, Chap 16.15; Chapter 16.7 Eq. 24 and 25.
