• Leaky and poorly insulated ducts typically raise heating and cooling costs 20% to 40%
• A conservative estimate is ducts waste over $10 billion in energy in residential homes
• HVAC ducts are “low-hanging WSEC-R fruit”
• Design HVAC within the conditioned space?
• Why drive a Tesla on flat tires?

• The hole needs to be connected to the outside
• Heat loss is proportional to temperature and pressure differences
• Holes that see high pressures and high temperature differences are most important for energy savings
In heating climates, this is the supply side near the air handler
In cooling climates this is the return side near the air handler

• Airflow in = airflow out, so
flow through fan = flow through leaks in system
• CFM25 is an aggregation of all holes throughout the entire duct system – that’s all!
It does not tell us where to find the holes
It does not tell us how much the ducts leak under normal operating conditions
Without a blower door, it does not tell us how much of the holes are connected to the outside

• Duct leakage to the outdoors measures effective duct leakage to the outside
• Combines a blower door with the duct blower
• Total duct leakage measures leakage to indoors and outdoors
Both tests provide cubic feet per minute (CFM) duct leakage numbers

• Close exterior windows and doors
• Close fireplace and stove doors
• Close dampers (depressurizing the house sucks gravity dampers closed)
• Plumbing traps must be filled with water or blocked in some other manner
• Open interior doors
Did I fill the plumbing traps?

• Determine leakage rate of house with blower door (CFM @ 50 Pascals)
• Calculate to volume of the house (ft3)
ACH50 = (CFM x 60) ÷ volume

• 2,000 sf house
• Volume = 16,000 ft3 (2,000 x 8)
• Blower door CFM = 1,300 CFM
• ACH50 = (CFM x 60) ÷ volume
• ACH50 = (1,300 x 60) ÷ 16,000
• ACH50 = 78,000 ÷ 16,000
• ACH50 = 4.8
