The Journal of Solar Energy Engineering - Including Wind Energy and Building Energy Conservation - publishes Research Papers that contain original work of permanent interest in all areas of renewable energy and energy conservation as well as discussions of policy and regulatory issues that affect renewable energy technologies and their implementation. Papers that do not include original work but nonetheless present quality analysis or incremental improvements to past work may be published as Technical Briefs. Review papers are accepted but should be discussed with the Editor prior to submittal. The Journal also publishes a section called Solar Scenery that features photographs or graphical displays of significant new installations or research facilities. The ASME Journal of Solar Energy Engineering is published quarterly (February, May, August, November) by ASME, Three Park Avenue, New York, NY 10016-5990. This journal is sponsored and supported by the ASME Solar Energy Division.
