With a heavy emphasis on “green” technologies, the American Society of Heating, Refrigeration and Air-Conditioning Engineers says the “rain city” of Seattle is a good site for its annual conference.

The event takes place June 28-July 2 at the Sheraton Seattle and Washington State Convention Center. Taking place again this year is a research “summit,” which will target high-performance building and HVAC designs. Keynote speaker will be energy journalist Robert Bryce, a senior fellow at the Manhattan Institute.

A number of technical tours and leisure activities are planned. Details are available at www.ashrae.org/seattle.
