WINDHAM >> Four long-established architects will explore recent projects that contain innovative ideas in the integration of high conservation and alternate energy solutions with real world conditions and constraints, on Aug. 20, from 1 to 5 p.m.

Speakers include Roc Caivano, from Maine, who converted a military base brick building to a state-of-the-art research facility. Lawrence Linder, of Louisiana, has created a generic housing type that can restore urban street fronts broken by parking lots, increasing density, and be aloof from flooding. Robert Shannon, of New Mexico, has combined a new type of SIPS panel with aerated-autoclaved concrete exterior panels and solar air collectors to produce three residential structures. And Dan Scully, of nearby New Hampshire, has transformed a 19th century mansion designed by Peabody and Stern into a carbon neutral future.

Each architect will discuss his project — each of which will be presented on the gallery walls during the forum. A question and answer period will be included, followed by a reception with food and drink.

A free event sponsored by the Fourth Corner Foundation. To reserve a spot, RSVP by Aug. 15 to or 802-875-2194.
