Harlan H. Bengtson, Ph.D., P.E.
Course Outline
This course identifies and describes six components that typically make up a passive solar heating system and five basic types of passive solar heating systems. Sources of data on solar radiation rates and on heating requirements are discussed and estimation of the heating load for a building is discussed and illustrated with an example. Estimation of the fraction of heating requirement provided by a passive solar heating system of specified size at a specified location is discussed and illustrated with examples.
This course includes
a multiple-choice quiz at the end, which is designed to enhance the understanding
of the course materials.

This course is intended for mechanical, electrical and energy engineers.
Benefits
to Attendee
An attendee of this course will have basic knowledge about passive solar heating system components and types of systems. The attendee will also be able to obtain required data on heating requirements & solar radiation rates, and will be able to make calculations to estimate building heat loss, and fraction of heating requirement provided by a passive solar heating system of specified size at a specified location.
Course Introduction
A passive solar system for space heating converts the sun’s radiant energy to heat upon absorption by the building. The absorbed thermal energy (heat) is stored in components of the building and/or used directly to heat the building. In a strictly passive system, energy flow within the building is by natural means (conduction, natural convection and radiation). This course describes components of and types of passive solar heating systems. It also presents methods of obtaining required data and making calculations on performance of a passive solar heating system.
