Effects of internal gain assumptions in building energy calculations /

The utilization of direct solar gains in buildings can be affected by operating profiles, such as schedules for internal gains, thermostat controls, and ventilation rates. Building energy analysis methods use various assumptions about these profiles. This paper describes the effects of typical internal gain assumptions in energy calculations. The results of this study indicate that calculations of annual heating and cooling loads are sensitive to internal gains, but in most cases are relatively insensitive to hourly variation in internal gains.

The growth of silicon sheets for photovoltaic applications /

The status of silicon sheet development for photovoltaic applications is critically reviewed. Silicon sheet growth processes are classified according to their linear growth rates. The "fast" growth processes, which include edge-defined film-fed growth, silicon on ceramic, dendritic-web growth, and ribbon-to-ribbon growth, are comparatively ranked subject to criteria involving growth stability, sheet productivity, impurity effects, crystallinity, and solar cell results. The status of more rapid silicon ribbon growth techniques, such as horizontal ribbon growth and melt quenching, is also reviewed. The emphasis of the discussions is on examining the viability of these sheet materials as solar cell substrates for low-cost silicon photovoltaic systems.

Solar thermal electric power information user study /

This report describes the results of a series of telephone interviews with groups of users of information on solar thermal electric power. These results, part of a larger study on many different solar technologies, identify types of information each group needed and the best ways to get information to each group. The report is one of ten discussing study results. Results from five solar thermal electric power groups of respondents are analyzed in this report: DOE-funded researchers, non-DOE-funded researchers, representatives of utilities, electric power engineers, and educators.
