LIVING SYSTEMS

DECEMBER 1978


I. SYSTEM DESCRIPTION

The Living Systems site is a single-family residence in Davis, California.
The home has approximately 1700 square feet of conditioned space. The solar
energy system consists of two independently controlled systems: An active
system for preheating domestic-hot-water (DHW) and a passive system for space
heating the home.

The active solar DHW system has an array of flat-plate collectors with a gross
area of 46 square feet. The array faces south at an angle of 45 degrees to
the horizontal. Potable city water is the transfer medium used throughout the
system. When water in the collector is sufficiently warmer than that in the
preheat tank, the controller starts the circulation between the preheat storage
tank and the collector. The preheat tank holds 82-gallons and water is supplied,
on demand, to a conventional 20-gallon DHW tank. When the water preheated by
solar energy is not hot enough to satisfy the hot water load, a natural gas
burner in the 20-gallon DHW tank provides auxiliary energy for water heating.
The system is shown schematically in Figure 1.

The passive solar space heating system is of the direct-gain type illus-
trated schematically in Figure 2. Incident solar energy is admitted to the
building through both the large south-facing vertical windows (approximately
200 square feet) and the overhead skylight (approximately 80 square feet at
60 degrees from the horizontal). Manually operated insulating curtains pro-
vide insulation during the night and sunless days for the south-facing col-
lector windows; manually operated insulating shutters provide night insula-
tion for the skylight glazing and are aluminum coated to provide reflection
to the space below when open. Solar energy storage is provided by blue-
painted steel water-filled tubes containing approximately 3600 gallons of
water placed near the south window wall and under the skylight. Additional
storage is provided by the 6-inch-thick concrete slab floor of the building
which is covered by brown tiles. Collected solar energy is distributed by
natural convection, by conduction through the slab, and by radiation. Floor
covering is minimal: linoleum in the kitchen and eating area and white shag
rugs in two bedrooms. The building envelope is well insulated in order to
ensure energy conservation, with R-19 insulation in the walls and R-30
insulation in the roof. The effective R-value of the window areas with
curtains and shutters in place is in the range of R-2 to R-10. All glass
surfaces are double-glazed with minimum window area in nonsouth-facing
walls. Auxiliary space heating is provided by a gas-fired wall furnace; as
with the solar heating, natural convection distributes the heat. Additional
auxiliary energy can be supplied from a wood-burning stove.

Building summer overh_-jt protection is provided by several means: First,
roof overhangs over the south-facing glazed areas provide shading; second,

operable windows in the south wall along with a vent in the north wall are
used for r,,ss-ventilation of the house at night, cooling the solar storage
russ and providing moderation of daytime building temperatures; third, the
curtains and shutt-,r- over the windows can be closed during the day to pre-
vent collection of incident solar energy. When necessary, a ceiling fan is
available to assist distribution of heating and venting.


I I. PERF',IMCE EVALUATION


IN- JCTI 'I

.!-;:o ,.. e evaluation is presented in two parts for this solar energy site:
The first part covers the active solar DHW system; the second covers the
I :ssive solar space heating syst.-:-ii.

c r.:.nications system was operable only during the last 16 days of the
ith and the active solar DHW system was extensively damaged by freezing on
,er 8. Only limited information is available on the active DHW system.
The passive solar space heating system provided over 50 percent of the space
i.* ting ,.,.r,.,nd during the month. Operation of the wood-burning stove during
.-ri .is of l -wi incident solar energy provided backup energy while reducing the
s,..ce -,.ting d0-,:.and. Daily variations in building temperature were minimal,
ir 'i ting the presence of substantial amounts of energy storage capacity.
ort l,-.,els -*'-.iined reasonable throughout the month.


STH _NDITIO''S, ACTIVE SOLAR DHW SYSTEM

rinL the oith total incident solar energy on the DHW collector array was
0. 6 million Btu for a daily average of 606 Btu per square foot. This was
I-1 t.-.: estimated average daily solar radiation for this geographical area
duirng ..', br of 943 Btu per square foot for a south-facing plane with a
tilt of 5 :rees to the horizontal. The average ambient temperature during
r was ', F as comwp.ared with the long-term average for December of



SERFi'. ,NCE, ACTIVE SOLAR DHW SYSTEM

11 :tor The total incident solar radiation on the DHW collector array for
f c er was 0. 6 million Btu. During the brief period of the
S col tor was o., native, no info,-: tion was available. luring
.. nth n th data was collected and the Ch',-; collector
S tora i es, sr.ors, etc. were still .,orking. There
e f 1 million OBt f.--. the passive heating syste, into the DHW
S, ting in an effective collector a-r.iy efficiency of 7
s on o l incint insolation. There was no operating energy
Sa ive lcol ctor loop.

S y 0.061 million tu of solar eneri,' and 1.8
Sx l ia, er al ner' / (.* jivalent to 3.0 millionn Btu of








auxiliary fossil fuel energy) to satisfy a hot water load of 1.9 million Btu.
The solar fraction of this load was 11 percent. The passive system spill-
over resulted in fossil fuel energy savings of 0.10 million Btu. A daily
average of 122 gallons of DHW was consumed at an estimated average temperature
of 1220F delivered from the tank.


WEATHER CONDITIONS, PASSIVE SOLAR SPACE HEATING SYSTEM

During the month, total incident solar energy on the passive collector south
windows and skylight was 5.4 million Btu for a daily average of 633 Btu per
square foot. This was below the estimated average daily solar radiation for
this geographical area during December of 982 Btu per square foot for a
south-facing plane with a tilt of 60 degrees to the horizontal. The average
ambient temperature during December was 38F as compared with the long-term
average for December of 460F.


THERMAL PERFORMANCE, PASSIVE SOLAR SPACE HEATING SYSTEM

The total incident solar radiation on the collector windows for the month of
December was 5.4 million Btu. The total solar energy for the month of December
delivered to the space heating load was 4.4 million Btu, resulting in a
collector array efficiency of 82 percent, based on total incident insolation.
Auxiliary thermal energy of 3.7 million Btu (equivalent to 7.3 million Btu
auxiliary fossil fuel energy) was added to satisfy a space heating load of 8.0
million Btu. This resulted in a fossil fuel energy savings of 7.3 million
Btu. The solar fraction of this load was 55 percent. The average storage
temperature for the month was 69'F.

On many days during December, the wood-burning stove was used to satisfy a
measurable amount of the building load. The thermal energy derived from
operation of the wood-burning stove is applied as a reduction to the building
load; that is, the major difference between the building load and the space
heating demand is the energy derived from operating the wood stove. During
December, this renewable energy was approximately 1.9 million Btu. Assuming a
wood stove energy conversion efficiency of 30 percent, this 1.9 million Btu is
approximately equivalent to 21 percent of a cord of dry hardwood (such as oak).
In terms of the savings of nonrenewable energy, this renewable thermal energy
derived from the wood is equivalent to over 3.2 million Btu of fossil fuel
energy.

The interior comfort level was given as 68'F in zone 1, the south end of the
building, and 66F in zone 2, the north end. The temperature difference
occurs because comfort zone 2 is heated by conduction through the slab and
walls, and by convection and infiltration associated with the doors. The
cooler temperatures in the bedrooms do not seem objectionable.


OBSERVATIONS

During the month of December, the new owner was still moving in and not fully
advised of the normal usage of a passive solar home. The insulative shutters,
one of the back doors, and the insulative curtains were not fully operational.









rin ir 23 to ?''' r 26 holiday season, measurement values were
bn ause the 'J stove overheated; the windows and vent were opened
S an s tur~ i on, so, iti. !t-S for an extended period on cloudy days.
r the their -istat ..',.s raised ard fossil fuel was used to heat


jt, forL I'-.,els inside the building were reasonable during the entire
nth in zr.s of 'h, building. Zone 1 was the primary collection and
o a' of house. The nifort level in zone 2 was slightly lower
S *t i 1 ie to the .-.thod of trarnferring heat to zone 2. Daily
vri Lio in building t, :.,.,ratur--, averaged only 6VF for the month with a
vari>ti .ii of 10 F center, I on 70.5F occurring on both December 15 and


S s froze on DeiuLi:ber 8, apparently due to an installation problem.
*rijn-' in*n controls operated prop',,rly, but sufficient water remained in
e _to freeze and destroy them. With the collectors inoperative,
rsi rble spill-over of solar energy occurred from the passive system
t -,rtion of the i':,nth when data was being collected.


e solar er ,' system provided a total fossil fuel energy savings of 7.4
I tu. Although the DHW system was inoperative, it received an energy
!st f. re .Issi..;. system for a fossil fuel savi-gs of 0.10 m-illion Btu.
Te s ce ating syst-:i contributed an energy savings of 7.3 million Btu.



III. TICO: STATUS

e tive system was inoperative and requires major repair; insulative
s ters nd curtains require s ,- work by i. Intee or owner. Boeing has
t cr ir i 'e *r.' direction indicator and has to replace the DHW collector
f] ter by '-e ti '- the DK.-J system is repaired.
