Innovative Design
's long history of energy efficient buildings has evolved from residentail projects with passive solar strategies in the 1970s and 80s. All projects included passive solar strategies such as southern orientation, proper overhang for heat gain control, thermal mass and natural ventilation. Many projects also included solar domestic hot water and photovoltaics.
Between 1980 and 1984, our firm organized and conducted a national, award-winning program geared at implementing passive solar in speculative home market, The Solar Spec program. As a result of this effort, we successfully achieved an average reduction of 40% or more in energy consumption in the homes of the 25% of the builders in North Carolina who participated. These superior passive solar homes have been built repeatedly for over 4,000 residences.
