Studies & Reports
The following reports were authored or co-authored by Bright Power staff:
- The Negative Impact Of Cold Water Bypass On Solar Domestic Hot Water Systems - Bright Power, Inc. (NYSERDA and New York City Economic Corporation, August 2011) Post-installation monitoring of a 24 collector SDHW system recently installed in the Bronx revealed that the overall performance of the system is far lower than expected. The initial hypothesis for the cause of this reduced performance posited that less water is being drawn through the preheat tanks than designed for, thereby impeding the distribution of the thermal energy collected and reducing the efficiency of the solar thermal system. To investigate this theory, a study was commissioned to analyze the internal dynamics of the system.
- Solar Real-Time Pricing: Is Real-Time Electricity Pricing Beneficial to Solar PV in New York City? - Bright Power, Energywiz, Association for Energy Affordability (New York City Economic Development Corportation, July 2009) A study analyzing if real-time pricing in the form of Con Edison's Rider M tariff can improve the economics of solar electric photovoltaic (PV) installations, as well as facilitate greater use of hourly pricing within the New York City area.
- Solar Domestic Hot Water Technologies Assessment - Jeffrey Perlman and Andy McNamara (NYSERDA, August 2008). A report by Bright Power that compares the energy and economic performance of solar against conventional domestic hot water heaters in 13 regions of New York, using the TRNSYS hourly simulation tool.
- CUNY Solar Training - Market Assessment (PDF, 634 kB) In 2008, Bright Power conducted a comprehensive market assessment of the demand for a solar electric photovoltaic (PV) system installation technical training program in New York City. The study was funded by NYSERDA and was performed under contract to the Environmental Business Association of New York State, for the City University of New York (CUNY). Bright Power's report found a growing demand for solar photo-voltaic installation training in New York City, driven by an increase in solar installations in the area. Typical PV installations in New York City have characteristics that differ from systems in other locations. The report also outlines a marketing plan to attract students to the program. The City University of New York (CUNY) is developing a comprehensive training program for PV installers that will be accredited by the Institute for Sustainable Power (ISP).
- Greening A Block Feasibility Study - Charles Komanoff and Jeffrey Perlman (Greening A Block, January 2006). A proposal to take a whole city block and transform every building on it into a green, energy-efficient version of itself.
- National Review of Green Schools: Costs, Benefits, and Implications for Massachusetts (PDF, 800 KB)- Greg Kats, Jeffrey Perlman, and Sachin Jamadagni (Capital E, December 2005). Report for the Massachusetts Technology Collaborative, reviewing the costs and benefits of green schools. These benefits include: energy savings, emissions reductions, water and wastewater reductions, increased earnings potential for students, asthma reduction, health improvements (cold/flu reduction), and increased teacher retention.

- Analysis of PV System Performance Versus Modeled Expectations Across a Set of Identical PV Systems - Jeffrey Perlman, Andy McNamara, Dante Strobino, BASIC (American Solar Energy Society, Summer 2005). A study analyzing the outputs of various solar PV arrays in the real world versus their expected outputs.
- The Costs and Financial Benefits of Green Buildings - Greg Kats, Leon Alevantis, Adam Berman, Evan Mills, Jeffrey Perlman (Capital E, October 2003). A report to over 40 California state agencies demonstrating the conclusive findings that building green is a worthwhile investment.
