Mode 2 Storage-to-Classrooms (Occupied): This mode is entered at the
beginning of each school day as determined by a seven-day clock timer.
Circulation fan Fl runs continuously to transfer energy from storage, to
classrooms, and to provide ventilation. Outside air and return air
dampers are modulated to supply fresh air at a mixed return air tempera-
ture of 60F. Multizone control dampers modulate the mixed return air
with thermally heated air from storage to maintain the space heating sys-
tem supply air temperature. The auxiliary fuel-oil boiler supplements
solar energy to meet the space heating demand, and to maintain the build-
ing's indoor ambient temperature. The seven-day clock timer terminates
this mode at the end of each school day. The clock timer may be manually
overridden to provide Mode 2 heating for irregularly scheduled (outside
normal class hours) school events.


Mode 3 Storage-to-Classrooms (Unoccupied): This mode is entered when
there is a demand for space heating and the system is not in the Occupied
mode. The outside air damper Dl is closed. Circulating fan Fl runs when
a space heating demand exists to transfer energy from storage to class-
rooms, and to provide ventilation. Multizone control dampers modulate
the return air with thermally heated air from storage to maintain the
space heating system supply temperature. The auxiliary fuel-oil boiler
supplements solar energy to meet the space heating demand and to maintain
the building's indoor ambient temperatures. This mode terminates when
either the demand for space heating ceases, or the system is changed to
the Occupied mode.


Mode 1 operation can occur while either Mode 2 or 3 is active.


II. PERFORMANCE EVALUATION


The system performance evaluations discussed in this section are based
primarily on the analysis of the data presented in the attached computer-
generated monthly report. This attached report consists of daily site
thermal and energy values for each subsystem, plus environmental data.
The performance factors discussed in this report are based upon the

million Btu) is believed to have migrated to the building and contributed
to satisfying the space heating demand. Thus, the measured space heating
mand, when combined with the circulating fan and the rock thermal storage
energy contributions, results in an indicated space heating demand of 44.3
million Btu, which compares favorably with the predicted load of 46.9 mill
Btu.


D. Observations


The performance of the solar energy system continued to improve over the
winter months. The collector array efficiency normally increases as the
operating point moves from winter to spring. This is consistent with an
air system in which the collector array return air temperature is nearly
constant, which is the case for the Northview Elementary School (Howards
Grove) solar energy system. As the ambient outside temperature rises, the
operating point shifts toward lower values and the collector efficiency
increases.


E. Energy Savings


The solar energy system installed in Howards Grove School resulted in an
indicated savings of 11.14 million Btu (77 gallons) of fuel oil during May
at an expense of 1.88 million Btu (550 kwh) of electrical operating energy
The space heating energy savings calculations are based on the energy re-
quirements of a conventional propane-fired furnace with an efficiency of 7
percent compared to the energy requirements of the solar energy system.


The actual solar energy system's savings must include not only the direct
solar contribution from the rock thermal storage, but also the thermal 1r
contribution to the space heating demand. In addition, the fan energy ,
tribution should be considered an auxiliary contribution to the space'
demand. When these additional energy contributions are considered, t









vings become 44.34 million Btu (308 gallons) of fuel oil. Also, the solar
ntribution to the space heating load increases from 64 percent to 76 per-
nt.


I. ACTION STATUS


ditional instrumentation is being suggested to resolve the discrepancy
tween space heating demand measured by different instrumentation sensor
ts. This would allow a more accurate determination of solar energy con-
ibution and identify the source of the faulty sensor indications.
