Course Description

It will also be of interest to any engineers wanting to learn more about the renewable energy field.  The principles of passive solar heating, such as basic types of systems, their description, and the components making up any passive system are presented in this course.  Sources of data for heating requirements and available solar radiation throughout the U.S are identified and discussed along with a method for estimating the rate of heat loss from a home.  The use of these three inputs in a method for estimating performance of a passive heating system of specified size at a specified location is presented.  The data retrieval and calculations are illustrated with numerous examples.


Course Objectives

Upon successful completion of this course, participants will be able to:

  • Obtain and interpret data for solar radiation rate on vertical and horizontal surfaces of buildings for any of the 239 locations in the NREL database..
  • Obtain and interpret data for heating degree days at any of the 239 locations in the NREL database.
  • Calculate an estimated rate of heat loss (Btu/oF-day/ft2) from a building if one year’s monthly power bills for the building are available.
  • Calculate an estimated monthly percentage of a building’s heating requirement that will be provided by a given size passive solar heating system at a given location in the U.S. it specified rate of heat loss from the building in Btu/oF-day/ft2.
