GUILDERLAND — Last May, George Keleshian got a new address and, when he recites it, he enunciates every syllable with a propriety tone.

When Keleshian built his energy efficient home on Johnson Road in 1980, he planned to build three more houses to create Solarview Estates.  His home’s new address, 100 Solarview Lane, heralds the beginning of his long-planned project, since his private road off of Johnson has been officially recognized by the town and his subdivision has been approved.

Now the president of Zeroenergy, Keleshian has a history of environmentalism, dating back to his undergraduate years at the University at Albany in the late 1960s.

“Back in 1969, I took a course, ‘Man Against his Environment,’” Keleshian said of what brought him to environmentalism.  He credits his professor, Louis Ismay, with putting him on his path, and, referring to his career and new company, said, “I’m still doing his course — it’s a long three credits.”

His company, which is in the process of moving to Guilderland, designs and builds houses and commercial and municipal buildings that don’t depend on fossil fuels.  It also retrofits houses to be more energy efficient, Keleshian said, noting that the great majority of houses already built are not energy efficient.

“It’s very easy for me to build a zero-energy building new,” he said, and then asked, “What about the 95 percent of houses already built?”

“God has provided mankind with everything we need,” Keleshian said, explaining that there are different sources of energy all around the world that people haven’t been focusing on.  “We’re going to have to make a leap in a new direction,” he said, referring to the current energy situation.

Anticipating that leap, Keleshian has brought together seven of the Northeastern alternative-energy manufacturers with whom he has worked over the last 30 years and he has plans to make Zeroenergy into a national company.  “It took four or five years for me to get everyone together under one roof,” he said, and he’d like to start wholesale marketing across the country.

“The beauty of our system is simplicity,” he said.
