A Martin Garage Door system is energy efficient, findings from a solar test home project show.
Those findings come in relation to a garage door that Martin contributed to a solar home make-over in Holladay, Utah in March of 2009.
The findings include the following facts and data:
---Martin Door's DC opener cuts down on power usage. The homeowner found the old garage door opener was heavy on energy usage in comparison to the new opener. It takes approximately 40 watts of power to operate the opener, according to Ned Hart, marketing director for TerraSun Energy. He said the old opener used about 440 watts to open or close the door The family cycles the garage door about 600 times a month, so Hart estimated a substantial savings in energy, with the Martin DC opener.
“This is a dramatic energy savings over the course of a month, reducing energy consumption from 4500 watts to 435 watts each month, or 48,000 watts annually. For solar homes, this is a REALLY big deal,” Hart said.
---the Martin opener also facilitated use of CFL or LED bulbs, while the old opener did not. That cut energy usage from 120 watts to three, according to the energy official.
---the double pane acrylic windows used made a big difference in energy savings in the garage. Hart said the added insulation factor from the door has made a noticeable difference in the garage temperature, and thus has impacted the temperature of the home itself. As part of the energy efficiency upgrades, workers applied Temp-Coat, an insulating paint, to the walls of the garage adjacent to the home.
Test data and measurements are constantly being taken. “You have a great product, and we will be heartily recommending it to every customer,” Hart said.
Before the project began, the home’s gas and electric bills for January, 2009 alone totaled $460. The goal for the home is “0” monthly gas and electric utility bills. Various measures are being taken to accomplish this.
For example, during the day the surplus electricity generated by the solar panels actually backs up the meter. At night, the meter moves forward as electricity is consumed from the land line.
Updates to the home include the insulated Martin Garage Door, Martin DC3700eO belt drive opener, energy efficient heat pumps, a biomass boiler, solar electric and hot water panels, extra insulation, tree management (shading solar panels), new roof shingles, etc.
