Bruce Brownell, of Adirondack Alternate Energy, has been creating low-energy, largely passive-solar-heated, resilient homes in the Northeast for forty years — and he’s still going strong. Since 1973, Bruce has built more than 375 homes in 15 states, a third of them in very cold (over 8,500-degree-dayMeasure of how cold or warm a location is over a period of time relative to a base temperature, typically 65°F (although other base temperatures, such as 75°F, can be used for cooling). To calculate the number of heating degree-days (HDD) of a given day, average the maximum and minimum outdoor temperatures and subtract that from 65°F. The annual number of heating degree-days is a measure of the severity of the climate and is used to determine expected fuel use for heating. Cooling degree-days (CDD), which measure air conditioning requirements, are calculated by subtracting the average outdoor temperature from an indoor base temperature.) climates. Most require just a few hundred dollars of heat per year.
