Solar Heating
Solar energy may be utilized to provide part or all of a building’s
space-heating requirements, for domestic or process water heating, as
the heat source in an absorption refrigeration cycle, and in many other
useful ways. Technically, the most important problems have been
solved. At this writing, active solar heating systems have such a high
first cost that the economic recovery period is excessive in all but a
few special cases. This will change only when conventional fuel costs
increase to several times their present rate or when some way is found
to decrease the first cost of solar heating systems. For a full discussion
of solar heating design, see the chapter on solar energy in the
ASHRAE Handbook.
