The Propane Energy Pod: Behind the Numbers

How modeling analyses of home energy consumption and CO2 emissions gave rise to the Propane Energy Pod.

The research behind the innovative Propane Energy Pod is extensive, detailed, and as up to the minute as possible. Carried out by Newport Partners, a Davidsonville, Md.-based research firm with a long history of work in the energy field, the numbers tell a distinct story.

In four different climate zones, two sizes of Propane Energy Pod homes and two sizes of "standard" homes (2,400 square feet and 3,600 square feet), both two-story, single-family detached plans, were compared in three areas: annual energy cost; annual CO2 emissions; and HERS Index scores.

In every case the Propane Energy Pod home outscored the standard home in all categories. The most noteworthy findings were as follows:

  • In the Annual Energy Cost category, the 3,600-square-foot Propane Energy Pod home in a cold climate zone (Northeast) was projected to save residents more than $500 per year in energy costs.
  • In the Annual CO2 Emissions category, the 3,600-square-foot Propane Energy Pod home in a cold climate zone (non-Northeast) came out the best with a savings of 11.29 metric tons of CO2 emissions.
  • And in the HERS Index category, the 2,400-square-foot Propane Energy Pod home in a cold climate zone (non-Northeast) showed the biggest difference between scores. (The HERS Index is a system that measures the energy efficiency of a home on a scale of 0 to 100; the lower the score the better.) The Propane Energy Pod home's HERS Index was 67 compared to 86 for the standard home. In other words, the Propane Energy Pod home was 33 percent more efficient than a home built to code, while the standard home was only 14 percent more efficient.

For those less inclined to do the math themselves, the Propane Energy Pod Interactive Tool (coming this summer) will allow users to compare the performance of a Propane Energy Pod home to a standard home built in their geographic area. A side-by-side comparison of the two homes will show exactly how much energy and emissions savings the Propane Energy Pod model can achieve by combining the individual benefits of efficient propane appliances.
