Passive House Institute U.S. Schedules Conference

The 9th annual North American conference will take place in San Francisco in September 2014

Passive HouseA residential building construction standard requiring very low levels of air leakage, very high levels of insulation, and windows with a very low U-factor. Developed in the early 1990s by Bo Adamson and Wolfgang Feist, the standard is now promoted by the Passivhaus Institut in Darmstadt, Germany. To meet the standard, a home must have an infiltration rate no greater than 0.60 AC/H @ 50 pascals, a maximum annual heating energy use of 15 kWh per square meter (4,755 Btu per square foot), a maximum annual cooling energy use of 15 kWh per square meter (1.39 kWh per square foot), and maximum source energy use for all purposes of 120 kWh per square meter (11.1 kWh per square foot). The standard recommends, but does not require, a maximum design heating load of 10 W per square meter and windows with a maximum U-factor of 0.14. The Passivhaus standard was developed for buildings in central and northern Europe; efforts are underway to clarify the best techniques to achieve the standard for buildings in hot climates. Institute U.S. says that it is now accepting both papers and presenters for its annual North American conference, scheduled this year from September 10-14 at the Marriott San Francisco Waterfront.

PHIUS was still firming up its speakers and other conference details, and said it would have registration links posted at its website later in the week.

In the meantime, the organization announced the basic framework for the conference, including pre-conference technical workshops on September 10-11 covering topics such as WUFI-Passive, mechanical systems, and multi-family buildings.

The main conference takes place September 12 and 13 and will include four two-hour tracks each day. On September 14, there will be a bus tour of projects in the area.

An unrelated conference, the North American Passive House Conference, will take place this year in Portland, Maine, also in September. The Maine conference is sponsored by the North American Passive House Network.
