ABSTRACT
On a national level, lighting, cooling, electronics and motor loads make up one third of all the energy used in buildings and industrial facilities. The remaining two thirds of the energy load is for heating needs. This simple fact draws to mind a series of questions: Where should energy managers to put the greatest resources to improve energy efficiency, heating or non-heating loads. If heating is the largest load, why not apply cost effective solar heating to the loads? How can facility energy managers use reliable solar heating energy to cut energy use in their electric, gas, fuel oil and propane loads. Can solar heat provide other benefits such as improved indoor air quality or reliability?
There are several techniques to apply solar energy to new and existing buildings that can:
Cut energy use
Improve reliability
Improve profit margins
Figure 1 Heating energy use dominates
Provide quick paybacks
Improve indoor air quality
Provide additional building space
Provide air conditioning load reduction
Provide environmental benefits to pany
Improve regional and national energy independence
The paper will discuss how solar heating techniques have evolved since the 1970s
