BOURNE, MA, April 14, 2011 - A wind mapping study of Boston is being conducted to determine the feasibility of wind power for 10 high-rises throughout the city, including the Equity Office Properties building at 60 State Street and the Massachusetts Eye and Ear Infirmary.

Eastern Wind Power (EWP), the Cambridge, MA-based green energy technology firm conducting the study, claims that a "Sky Farm" consisting of ten 50 kilowatt vertical access wind turbines (VAWTs) can generate 10% of the energy that a typical 500,000 square foot high-rise consumes.

"One turbine can power a building's electrical emergency backup, eliminating the need for a diesel generator," said Jonathan Haar, president of EWP. "It can also produce more usable energy than a 10,000-square-foot solar photovoltaic array, at one-quarter of the capital cost."

To assess the potential for wind power, EWP has deployed weather stations from Bourne, MA-based Onset Computer Corp. to measure wind speed, wind gust, and wind direction at the test sites.

"The weather stations allow us to measure all three parameters simultaneously, and access the data online," said Linda Haar, board chair at EWP. "By charting microclimates in downtown Boston we will be able to help local companies learn if greening their sites with wind power is feasible."

The interest in harnessing wind energy is growing in the U.S. and around the world. Several trends and events are now converging that support such interest: a desire to lessen dependency on petroleum products; rising energy prices; and the recognition that environmentally sustainable building management practices can be both environmentally responsible and cost-saving.

In the City of Boston, July 2010 energy prices were up 78% as compared to July 2009, according to The Boston Business Journal. This rise is attributed to more energy consumption and to higher natural gas and oil prices, which are used to generate the majority of electrical power in Massachusetts.

Wind data from the top of the Massachusetts Institute of Technology's Green Building in Cambridge, MA has already helped EWP conclude that a single Sky Farm 50 kW turbine installed there will generate 55,000 kWh of electricity per year. This amount of energy can power six to eight homes.

EWP is currently gathering wind data from the roofs of both 60 State Street and Mass Eye and Ear. They plan to collect data from eight more high-rises in downtown Boston by 2013. Looking ahead, EWP plans to install at the City of Boston's Marine Industrial Park as its first high-rise turbine site in Boston.
