Gunn Memorial Library in Washington will present a program on the revolutionary energy performance approach of passive house design Jan. 28 at 6:30 p.m.

A snow date of Feb. 4 is set.

Hicks Stone, founder and principal of Stone Architecture, LLC in Roxbury will be the guest speaker for the program at the Wykeham Road library.

Passive house design seeks to use simple and inexpensive methods to reduce home energy consumption by 90 percent.

The methods are based on building research conducted in the U.S. and Canada and refined by German buildings scientists.

Rather than using exotic and expensive mechanical systems and controls, or incorporating unappealing aesthetic elements into the building design, passive house design is virtually invisible and is said to only modestly increase the cost of construction.

In this slide lecture, Stone will review the principles of passive house design and discuss how these can be easily incorporated into both new and existing building construction.

When put into practice, the cost of heating and cooling buildings will be dramatically reduced.

Stone, son of the late American architect Edward Durell Stone, opened his practice in 1991 in New York City after working as a senior designer in the office of Philip Johnson and John Burgee Architects.

He has a national practice with projects from Maine to Florida and the Bahamas to California.

His firm’s principal focus is the design of single and multi-family residential housing, retail boutiques and cultural facilities.

Stone is working on private homes in Connecticut that will seek certification from Passive House Institute as exemplars of modern, energy-conscious design.
