At Firestone we've engineered heavy equipment tires that play a vital part in developing Canada's energy resources. _ We've also engineered a new radial passenger tire that helps the Canadian motorist conserve energy.

The walls are insulated to RM, double that recom- mended by the. Ontario Building Code and CMHC. Insulation in the roof is R61. The New Trillium is high enough. wide enough. and long enough to setisfy any need a traveller might have, Its smooth fiberglass body gives it the best towing performance and least wind resistance of any travel trailer on the market.

Mrs. Rice says she was hoping they would not have to use their ttack-up system as much as they did. It is necessary that Mr. and Mrs. Rice switch on the fan which draws the heat from the roof to the rock storage bin. Mrs. Rice says they are not always able to take full advantage of the sun when both are working and not home to switch the fan on. The heated air is drawn to the base of the house by a power motor and blower which forces the warm air to the rock storage bin. With the open concept of the house, (six levels with four to five steps between each), heated air is allowed to rise to the top of the house and a return duct sends the warm air back down for dis- tribution throughout the house. This air is warmed when the sun‘s rays are attracted through the two layers of fi- breglags to the black traint- ed metal absorbers. The black sheets are co» vered by two inch fibre- glass. Cool air in the collec- tor comes through a vent formed by two rafters on the west end of the roof and even distribution results from suction across the roof to a vent between the rafters at the east end of the roof.' _ Sheet metal absorber plates. covered with a flat black paint are placed hori- zontally over the strapping. The south roof is con- structed with two. by 12inch Douglaslir rafters with alu- miniud gyproc laid on top plus two by four inch strap- pll'lg. . this was new to have a “Minted ,unount of sun- shine" but the is not sure if the winter um typical or ac- tually had fewer - days than usual.

BROWN BROTHERS CONTIACYOIS (TF3 A house in London which Mr. Fryett and Mr. Somfay designed cost $4,000. not in- eluding land costs or archi- tect fees. For the months of November. December and January, the electrical bill for hack-up heating and all major appliances was $4.00. Two other designs which the men have completed were done from standard home designs but changed to use the sun as a major sour- ce' of heat. For the $64,000 design. it will cost 88,000 for the extra devices used for solar. Some of these include a greenhouse. reorienting windows and insulation. A complete energy audit is required to tell what the payback period will be. A “0.000 home in Mono Mills. which was designed by Som- fay and Fryett, will have a payback period of - to tight years.

Changing ideals " ho se design Mr. Fryett works with air- chitect Joe Somfay and they have completed 12 solar heated homes in the past two years and expect to de- sign another five or six this year. by Rim Dodson "Young people are beco- ming painfully aware that they will not have the homes their parents did." says James Fryett, architect. “1 see in the future, higher density becoming a reality." says the Elora based architect who Specia- lizes in solar homes. Mrs. Rice believes if there was no solar heat She also estimates the amount of solar used was the same for both winters. This past winter the elec- trical bill was 8150 plus $100 for wood. "We halved our costs because we're using wood." said Mrs. Rice. Mrs. Rice estimated their savings for the past two years. Their electrical Mil for the first winter was 8650: the storage bin had not had time to store much solar heat so was not func- tioning at full capacity. Mrs. Rice says they have also installed a wood burn- ing stove and did not have to use the electric heat this past winter. They do have to buy "their wood: this winter they used about tour cords with a cord costing between $25 and $35. They have an insulated fireplace and a five kilowatt electric heater. This heater is equal to tive baseboard heaters and is able to heat the entire house without solar. /i , l -, / ueirtjlit,i,iy 237/ I pn' NN. 2 Ct:; "js","',",:')):):';)):;,,:::)::,,,,,,,,,,, i: r? iil Cl T\\>\; Some of his suggestions for energy saving in a home include an air-lock entry. placing heat generating rooms, such as the kitchen to the north side of the house and living ‘areas to the south. night insulation on windows - perhaps giving up the traditional sheer and de- creasing the size of our homes eliminating wasted space and rooms. One of the ways the design costs are kept down is to minimise the finishing touches to allow people to upgrade'the home at their own pace. . Solar is "pretty well our main business.” says Mr. Fryett. "It seems to be eoming the ideal." Mr. Fryett believes' we will have to re-examine how we define "house" and that many of our conventional ideas will have to be forgot- ten. The coat of the collector is about $5.” and it uses very conventional materials. The collector plate is aluminum. To add this collector to an existing home. however. would cost more. The collector design used on their solar homes was de- veloped by Somfay and Fryett. “It is easy to in- tegrate with a roof struc- ture," says Mr. Fryett. extra investment made for solar would be paid back in this period. The important fact is, the Rice family has proved Can- adians can live comfortably in a solar home. As the world situation becomes more precarious and the chance of our oil stippiies depleting becomes very real. it is apparent solar's time has come. Although Mrs. Rice was hoping for a more efficient active. solar system. many of us have to envy their heating and electrical bill Cor the past winter. Before completing the de- sign of the Rice home. Mr, Somfigy used computers at the university to simulate the validates in the house. Through juggling of these; it was determined on paper what would produce what approached solar self-ef- ficiency. boring the summer the windows can be opened to allow cool air to pass through the house. Windows at the top of the house can also be opened to allow warm air to leave. and, their out: each year wguld be about no» more.
