Passive House 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.
