LIVING SYSTEMS

JANUARY 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 soace 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 controller 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 uxiliary energy for water heating. The system is shown schematically in Figure 1.

The passive solar space heating systein is of the direct-gain type illustrated schei'atically in Figure 2. Incident solar energy is admitted to the building through botil 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 provide insulation during the right and sunless days for the south-facing collector windows. iianually operated insulating shutters also provide niqht insulation for the skylight glazing and are aluminum coated to provide reflection 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 storage 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, conduction through the slab floor, and by radiation. Floor covering is minim linoleum in the kitchen and eating area and white
sh- ,1 rugs in two bedroo1:m. 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 are in the range of R-2 to R-1O (uncovered and covered with curtains and shutters). All gldss 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.

II. L 1ORM. I VALUATION

I fiT: .)[Li T IO

'ror ance aluation is presented in two parts for this solar energy site:
The irst art covers the active solar DHW system; the second covers the ssive sola.r space heating system.

,e native solar DHW system was extensively damaged by freezing on December 8 t 1. limited information is available on this system. Spill-over from
t e vste: during the month of January satisfied 13 percent of the DHW J, .nile h< passi.e solar mace heating system satisfied 85 percent of the a s eatin; dem and during the month. Operation of the wood-burning stove rin periodss of low incident solar energy provided backup energy while u. in thie space heating demand. Daily variations in building temperature .,ere iinilal, indicating the presence of substantial amounts of energy storage ap.cit o ,iart levels remained reasonable throughout the month.


,;1!t:U CONDITIONS, ACTIVE SOLAR DHW SYSTEM

r e ionth total incident solar energy on the DHW collector array was
i iw t fr a daily average of 821 Btu per square foot. This was
S Sti i:ated average daily solar radiation for this geographical area .Oun, inuary of 995 Btu per square foot for a south-facing plane with a tilt of 45 degrees to the horizontal. The average ambient temperature during January was 44F as compared with the long-term average for January of 45cF.
Se er of eating degree-days for the month (based on a 65F reference) wa 001 as opared with the long-term average of 617.


T' .~,,, ~ CTIVE SO.]R DHW SYSTI

L11 :- T, total incident solar radiation on the DHW collector array for
t tI Iry was 1.2 illion Btu. The collector system was inoperative
Sage in Decerber; however, while the collectors were inoperative,
sensors, etc. were still working. There was leakage of 0.078
illi) a ro the passive space heating system into the DHW preheat system, resutin in an effective collector array efficiency of 7 percent, based on
1 ibn InFt insolation. There was no operating energy required by the it (rati /0o1 tor loop.








DHW Load The DHW system consumed 0.078 million Btu of solar energy and a measured 1.8 million Btu of auxiliary thermal energy (equivalent to 3.0 million Btu of auxiliary fossil fuel energy) to satisfy the hot water load of 1.9 million Btu. The solar fraction of this load was 13 percent. Losses from the DHW system were 0.031 million Btu. The passive system spill-over resulted in fossil fuel energy savings of 0.13 million Btu. A daily average of 124 gallons of DHW was consumed at an average temperature of 120'F 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 7.1 million Btu for a daily average of 842 Btu per square foot. This was below the estimated average daily solar radiation for this geographical area during January of 1027 Btu per square foot for a south-facing plane with a tilt of 60 degrees to the horizontal. The average ambient temperature during January was 44F as compared with the long-term average for January of 45F. The number of heating degree-days for the month (based on a 65F reference) was 601, as compared with the long-term average of 617.


THERMAL PERFORMANCE, PASSIVE SOLAR SPACE HEATING SYSTEM

The total incident solar radiation on the collector windows for the ilonth of January was 7.1 million Btu. The total collected solar energy for the month of January was 4.8 million Btu. In January, the total solar energy delivered to the space heating load was 5.0 million Btu, resulting in a collector array efficiency of 70 percent, based on total incident insolation. Auxiliary thermal energy of 0.87 million Btu was added to satisfy a space heating load of 5.9 million Btu. (This was equivalent to 2.1 million Btu of auxiliary fossil fuel energy, which includes the pilot losses not applied to the load.) The result was a fossil fuel energy savings of 8.3 million Btu. The sclar fraction of this load was 85 percent. The average storage temperature for the
month was 59'F.

On iiany days during January, 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 oas applied as a reduction to the building
load; that is. the major difference between the building load and the space heating demand was t;e energy derived from operating the wood stove. During January, this renewable energy was approximately 2.0 million Btu. Assuming a wood-stove energy conversion efficiency of 30 percent, this 2.0 million Btu is approximately eqptivalent to 22 percent of a cord of dry hardwood (such as oak). Tn terms of the savings of nonrenewable energy. the renewable thermal energy derived from the wood was equivalent to over 3.3 million Btu of fossil fuel energy.

The interior comfort level was given as 69F in zone 1, the south end of the building, and 66F in zone 2, the north end. The temperature difference
