"Greenest Design in America is Right Here"

Much like President John F. Kennedy’s challenge 50 years ago to beat the Russians to the moon, the green energy movement has tapped into many Americans’ competitive streak. This competitive spirit is embodied perfectly in the West Tisbury home of Alexander Boyle, which recently won a national award for the most innovative green energy design in the country.

The Boyle home was designed by Brian K. Nelson and David Sprague of Nelson Mechanical Design, and was built by general contractor Aaron Zeender. The home was selected for top honor by the Green Mechanical Council — formed to educate contractors and industry leaders about creating environmentally sound mechanical systems.

During a tour of the Boyle home this week, the three men who designed and built the home — Mr. Nelson, Mr. Sprague and Mr. Zeender — emphasized that Mr. Boyle did not build a green home with any thought of winning an innovative design award. But they did agree that this inherently competitive American spirit — the same that drives men to build a better mousetrap or design a faster car — will certainly play a role in placing this nation ahead of the green energy curve. “We like a challenge in this country,” Mr. Nelson said. “This time the challenge is not to win an award, but to end our dependence on [fossil fuels] and maybe even save the planet.”

Daikin Altherma Heat Pump systems available soon on Martha's Vineyard

The Daikin Altherma heat pump uses the stored solar energy in the outside air to heat water up to 130°F – even during the middle of winter. This heated water can be used for radiant heating systems and domestic hot water. The Altherma heat pump is also designed to work with solar hot water panels to create a truly energy efficient heating system.

The Altherma is a revolutionary air to water heat pump that will make combustion obsolete! We are getting a demo unit for Living Local on Oct 3rd – first time this unit has been shown in US outside a brief appearance in Chicago in January. It will be released in October for sale.

Operating costs will typically be half the cost of operating a similarly sized fossil fuel boiler – for example, if a home currently used $4,000 in propane a year with a boiler or furnace, the Altherma operating cost would be $2,000 in electricity a year with no propane bill.

The efficiency of the Altherma meets or exceeds that of geothermal heat pumps. Because with the Altherma there is no need for a geothermal field, the installation price will be about half that of a geothermal system. This heat pump represents a truly revolutionary advance and will be an essential part of the effort to make our island energy efficient and all electric.
