Transpired Collectors as Solar Air Preheaters

COURSE NO: R01-002
Transpired Collectors as Solar Air Preheaters
Course Highlights

This online engineering PDH course explains how solar collectors can save energy by serving as a means of preheating ventilation air entering a building.


The transpired collector is a simple, low tech, inexpensive means of preheating outdoor ventilation air coming into a building; thus reducing the energy requirement from traditional sources for building heating. It is basically a dark, perforated metal wall installed on the south side of a building to preheat incoming ventilation air entering the building from outside during the heating season.


This 1 PDH online course is intended for energy, mechanical, chemical, construction, and civil engineers. However, this course could appeal to engineers of other disciplines as well.

Learning Objectives

This PE continuing education course is intended to provide you with the following specific knowledge and skills:

  • Familiarizing with the components of a transpired solar collector
  • Familiarizing with the general configuration of a transpired solar collector
  • Knowing the building, site and climate characteristics necessary for a successful transpired collector installation.
  • Knowing the building, site and climate characteristics that would eliminate a building for transpired collector installation
  • Familiarizing with factors that make a transpired solar collector more cost effective
  • Familiarizing with sizing and energy saving calculations for a transpired collector
