LIVING SYSTEMS

APRIL 1979

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. In the event of freezing and no insolation, the con-
troller drains the water from the collectors. When water in the collector is
sufficiently warmer than the water in the preheat storage tank, the controller
starts the circulation between the preheat tank and the collector. The preheat
tank holds 82-gallons of water which 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 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 also provide night
insulation for the skylight glazing and are aluminum coated to provide reflec-
tion to the space below when open. Solar energy storage is provided by steel
tubes that contain approximately 3600 gallons of water. The tubes are painted
blue and placed near the south window wall and under the skylight. Additional

storaqjt is provided by the 6-inch-thick concrete slab floor of the building
which is covered by ceramic brown tiles. Collected solar energy is distributed
by natural convection, by conduction through the slab floor, and by radiation.
Floor covering is minimal: linoleum in the kitchen and eating area and white
shai 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-values of the windows (uncovered and
covered., with curtains and shutters) are 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 which
distributes the energy by natural convection. Additional auxiliary energy can
be supplied from a wood-burning stove.


The building has summer overheat protection which is provided by several
means: Roof overhangs over the south-facing glazed areas provide shading;
operable windows in the south wall and a vent in the north wall provide cross-
ventilation of the house at night, cooling the solar storage mass and moder-
ating daytime building temperatures; the curtains and shutters over the windows
prevent collection of incident solar energy during the day; and a ceiling fan
assists the heat distribution and the venting process.



II. PERFORMANCE EVALUATION



INTRODUCTION


Performance evaluation is presented in two parts for this solar energy site:
The first part covers the active solar DHW system; the second covers the
passive solar-space heating system.


The active solar DHW system, extensively damaged by freezing on December 8,
was repaired during April. However, during the interim period and the
repair activities, some sensors became inoperative; therefore, only limited
information is available on this system. The active solar DHW system satisfied







14 percent of the hot water load, while the passive solar space heating
system satisfied 100 percent of the space heating demand during the month.
The wood-burning stove was operated in order to reduce the space heating
load, but this occurred for only a few hours during the first morning of the
month. Daily variations in building temperature were minimal, indicating the
presence of substantial amounts of energy storage capacity. Comfort levels
remained reasonable throughout the month.



WEATHER CONDITIONS


The average ambient temperature during April was 570F as compared with the
long-term average for April of 580F. The number of heating degree-days for
the month (based on a 650F reference) was 341 as compared with the long-term
average of 227.


During the month, total incident solar energy on the DHW collector array was
2.0 million Btu for a daily average of 1485 Btu per square foot. This was
below the estimated average daily solar radiation for this geographical area
during April of 2011 Btu per square foot for a south-facing plane with a tilt
of 45 degrees to the horizontal.


During the month, total incident solar energy on the passive collector south
windows and skylight was 10.3 million Btu for a daily average of 1263 Btu per
square foot. This was below the estimated average daily solar radiation for
this geographical area during April of 1800 Btu per square foot for a south-
facing plane with a tilt of 60 degrees to the horizontal.



THERMAL PERFORMANCE, ACTIVE SOLAR DHW SYSTEM


Collector The total incident solar radiation on the DHW collector array for
the month of March was 2.0 million Btu. The collector system, inoperative
due to freeze damage in December, was repaired on April 23. However, while
the collectors were inoperative during the first part of the month, the
storage, pipes, sensors, etc. were still working. There was leakage of 0.024








million Btu from the passive heating system into the DHW preheat system.
When the system was repaired on April 23, the collector pump sensor was made
inoperative and the auxiliary fuel sensor load already failed on Merch 4. In
addition to the leakage, solar energy was collected for a total of 0.216
million Btu. The effective solar collector array efficiency was 11 percent,
based on total insolation. The operating energy required by the collector
loop was not measurable, despite the zeroes indicated in the printed report.


DHW _Load The DHW system consumed 0.216 million Btu of solar energy. The
hot water load was 1.6 million Btu. The passive system spill-over and the
energy collected after the system was repaired resulted in fossil fuel energy
savings of 0.36 million Btu. A daily average of 113 gallons of DHW was
consumed at an average temperature of 1250F delivered from the tank.



THERMAL PERFORMANCE, PASSIVE SOLAR SPACE HEATING SYSTEM


The total incident solar radiation on the collector windows for the month of
April was 10.3 million Btu. The total collected solar energy for the month
of April was 3.9 million Btu. The total solar energy delivered to the space
heating load was 3.7 million Btu, resulting in a collector array efficiency
of 36 percent, based on total incident insolation. Auxiliary thermal energy
was not used to satisfy the space heating load, and the pilot light was
turned off to save energy. The result was a fossil fuel energy savings of
6.1 million Btu. The solar fraction of this load was 100 percent. The
average storage temperature for the month was 680F.


During the early morning of the first day in April, the wood-burning stove
was used to satisfy a measurable amount of the building load. During April,
this renewable energy was only 0.042 million Btu. Assuming a wood-stove
energy conversion efficiency of 30 percent, this 0.042 million Btu is less
than 1 percent of a cord of dry hardwood (such as oak). In terms of the
savings of nonrenewable energy, the renewable thermal energy derived from the
wood was equivalent to over 0.07 million Btu of fossil fuel energy.








The interior comfort level was measured at 690F in both zone 1, the south end
of the building, and zone 2, the north end. A slight daily temperature
difference is usually expected because comfort zone 2 is heated by conduction
through the slab and walls, and by convection and infiltration through the
doors.



OBSERVATIONS


During the month of April, the passive solar system completely satisfied the
space heating with enough energy left over to raise the storage temperature
by 2F. The woodburning stove was used a few hours during the first day of
the month. With the space heating load reduced by milder weather, operation
of the reflective (and insulating) shutters and curtains was not as critical,
and the operational to incident solar energy went down. This resulted in a
lower solar conversion efficiency. The curtains are not yet fully operational.
With reasonably large uncurtained windows in the northeast bedroom, some
afternoon overheating has occurred. The DHW system was repaired during the
month. The monthly average DHW solar fraction was 14 percent for the last
seven days of the month; after the repairs, the solar fraction jumped to 41
percent.


Computed comfort levels inside the building were very stable during the
entire month in both zones of the building, varying at most by 10F over the
daily averages.


The fuel meter and collector pump sensors were inoperative and the water
meter read high. Installation of insulating curtains has not been completed
by the owner.



ENERGY SAVINGS


The solar energy systems yielded a total fossil fuel energy savings of 6.5
million Btu. The DHW system provided an estimated fossil fuel energy savings
of 0.36 million Btu, while the space heating system contributed a fossil fuel
energy savings of 6.1 million Btu.








III. ACTION STATUS


Boeing has been requested to inspect the sensor anomalies.
