Another passive design strategy is using insulation to minimize heat transfer in and out of the building.
R-values are the way we measure a material’s resistance to heat transfer over time. A material with a higher r-value is more effective at insulating than a material with a lower r-value.
At the R.W. Kern Center, we used materials with high r-values—like triple-pane glass windows, cellulose insulation, and an r-guard air barrier—to keep heat in or out. Having sufficient insulation in buildings increases energy efficiency by putting less stress on our heating and cooling systems.
