December 12, 08 Renee Co-OP Proto-type Solar System Fresh Meadows, N.Y.--U.S. Energy Group, a firm that develops and integrates energy control, monitoring and analysis systems for large residential properties, has launched USE Solar, a new solar energy initiative that focuses on the potential for multifamily and commercial buildings to use solar power. â € ¨Quixotic Systems Inc., a solar energy company offering consulting, design and engineering services, and Tristate Solar Inc., a solar energy system design, installation and service company, are working with U.S. Energy Group on the Renee and will install the photovoltaic system, which will consist of 142 solar modules of 200 watts each. Quixotic is designing the system and Tristate is working as a project integrator. The solar system is projected to provide 17 percent to 20 percent of The Renee ’ s common area electricity. Additionally, the system is projected to prevent the production of approximately 27,139 pounds of carbon dioxide each year. The New York State Energy Research and Development Authority (NYSERDA) is providing a $100,000 rebate incentive for this project, which may also receive federal and state tax credits and a property abatement tax of 8.7 percent for four years. In addition, the co-op can sell back the unused electricity to the grid and the tax credits will be passed along to the residents.

Residential Areas of Affordable Housing Projects: The *EPBI amount starting in 2007 is $3.50/watt. This applies to affordable housing projects of all sizes. Common Areas of Affordable Housing Projects: The EPBI level starting in July 2007 is $3.30/watt. This incentive level applies to solar electric systems serving the common areas of affordable housing projects.
