Water: The Ideal Thermal Mass? (EDC Magazine Edition)

A classic example of a roofpond application, the Atascadero House (Atascadero, Calif.) was designed with the assistance of Harold R. Hay and built in 1973. Photo credit: John Reynolds. Thermal mass is an essential component for any passive solar heating or cooling strategy. It’s useful because it absorbs solar energy and provides inertia against interior temperature fluctuations despite diurnal temperature cycles. Design teams can introduce thermal mass into projects in a number of ways. Baked clay, adobe and various types….

The Invention of the Roofpond System

The roofpond system has always been a dark horse of sorts in the realm of passive solar heating and cooling. Most literature on passive systems will pay lip service to roofponds, but few give credence to the system’s immense potential as exemplified by various case studies with well-documented performance. The reason that the roofpond is often overlooked is two-fold. First, the system has always had a difficult time  “fitting in” with any one category of environmental control systems. It can be used….
