LEED Interpretation Inquiry
Can Passive House projects use the PHI or PHIUS + approach to kitchen exhaust, as opposed to meeting ASHRAE 62.2 requirements of 5 ACH of the kitchen volume for continuous ventilation?
LEED Interpretation Ruling
Projects that are PHI or PHIUS + certified are permitted to use a continuous kitchen exhaust rate of 25 CFM per 2009 IRC table M1507.3, powered by an energy or heat recovery ventilator, but only if there are no combustion appliances in the kitchen (such as gas ovens or ranges). \n\n

Additional note: This ruling aligns with EPA ENERGY STAR for Homes and DOE Challenge Home ruling 00343, while adding in the requirement that no appliances can be combustion fueled.
