Brief abstracts of projects funded by the Energy Research and Development Administration (ERDA) and conducted under the National Program for Solar Heating and Cooling of Buildings are presented in three volumes. This, the second volume, identifies the major efforts currently underway in support of the national program. The National Aeronautics and Space Administration (NASA) is responsible for the management of the projects contained in the first section, Development in Support of the Demonstrations. The major thrust of this program is to ensure that truly marketable solar energy systems and subsystems will be available for testing and evaluation in the demonstration program. The second section of the report, Standards and Criteria Development, reflects the effort conducted by the National Bureau of Standards (NBS). It contains efforts underway to satisfy both ERDA and the Department of Housing and Urban Development (HUD) requirements for solar systems such as performance criteria; standards, test, and evaluation; and technical data requirements.
