Free and Open to the Public, Spread the Word!

We are proud to present guest speaker Douglas Mcdonald of, a Passive House expert, developer, and builder of Code Plus homes. Mr. Mcdonald’s presentation “What's So Special about a Passive House?” will cover the core concepts of a passive house, which is extremely insulated and virtually airtight. The design of these homes results in a 90 percent reduction of energy usage and minimal bills. Mcdonald created and lives in one of the first retrofitted passive houses in the country. There will be a Q & A session at the end of the program.

The Passive House standard has the most rigorous requirements for green building construction. Mcdonald will share his unique perspective of someone who actually lives in a 3,800-square-foot Passive House. This home was originally built in 1936 by Frank Lloyd Wright protege Barry Byrne, then transformed by Mcdonald into a super energy-efficient dwelling in 2012.

The temperature in Mcdonald's home is 73 to 74 degrees with relative humidity of about 45 to 50 percent all year round. 

Mcdonald's projects have been featured in New York Times Real Estate and selected for the Fine Homebuilding Reader Choice Award. Mr. Mcdonald has made guest appearances on The History Channel, where many of his innovative renovation ideas have been featured.

With his team of LEED architects and engineers, Mcdonald applies his unique and world class approach to creating iconic country homes utilizing the best building standards from around the world, including the Passive House standard, at a price comparable to conventional construction.

Passive homes maintain a comfortable interior climate  achieved through a system of interior and exterior air exchange, an airtight building envelope and energy-saving appliances. Additional energy needs can be generated by renewable sources. There are about 32,000 passive houses worldwide, most of them in Austria and Germany, but the designs are beginning to take root in America.
