Short trips gas eaters It's estimated that we use 30 per cent of our gaso- line on car trips of less than 8 km. These short trips con- sume fuel at a higher than average rate because the en- gine is cold for much of the time. Kilometrage improves greatly when an engine reaches its ideal operating temperature. Winter driving can increase fuel consump- tion up to 50 per cent. Stop- and-go city driving can cost even more. In light of the savings possible through careful trip planning or vehicle manage- ment, it's not surprising that large fleet operators devote great care to the operation of their vehicles. For a com- pany whose major overhead is transportation costs, trip economy can spell the dif- ference between profit and Popularity of Propane- Powered Vehicles Grows Propane as a vehicle fuel is becoming popular in Canada. This is the result, in part, of Canada's Propane Vehicle Program and the fuel's affordable price There are now more than 5500 propane fuelling Stations across the country that service the demand cre- ated by more than 70 000 propane-powered vehicles. Oil self-sufficiency is the main reason that the Government of Canada en- courages vehicle owners to switch to this Canadian fuel. Canada's Propane Vehicle Program offers taxable grants of $400 to vehicle owners to help offset the $1400 to $1800 cost of con- verting a vehicle. So far more than 33 000 vehicles have been switched with Government of Canada financial help. Besides the affordable price -- well below that of gasoline or diesel fuel -- it is propane's efficient perfor- mance in stop-and-go city traffic that makes it a prac- tical alternative. It is also in abundant supply; most of it is produced from natural gas, the remainder is a byproduct of oil. Other advantages of propane are extended engine life and reduced mainte- nance costs. Operating a car or truck on propane could double engine life because propane will not con- taminate engine oil or wash down the lubricant on cylin- der _ walls. Maintenance costs are reduced because oil and filter changes are required less often. The goal of the Govern- ment of Canada's Propane Vehicle Program is to have 100 000 vehicles operating on propane by the end of 1985. COMPLETE CHIMNEY CARE AND ACCESSORIES CHIMNEY SWEEPING - BUILDING-REPAIRS STAINLESS STEEL loss. To a private motorist the economies are not as obvious, but the opportuni- ties to save energy~ and money are certainly real. Let's look at a few of the tips that can add up to significant yearly savings. ® Do you really need to make this trip? Can you combine several errands or chores into one trip and save both time and money? Some of the alter- natives to climbing behind the wheel are a telephone call, public transporta- tion, walking, a bicycle and ridesharing. Planning ahead saves time and money. If you have a choice of vehicles, take the one adequate for the job -- the smaller the bet- ter. Use expressways, highways and bypasses whenever possible to minimize stop-and-go driving. If you are going to an unfamiliar place get good directions so you don't strain your temper or wallet searching for the right destination. @ Allow plenty of time to reach your destination. Don't put yourself behind the 8-ball by rushing to meet deadlines. Driving to beat the clock forces you to speed here, brake sharply there, accelerate too rapidly and generally waste fuel while putting unnecessary strain on your car.

It pro- vides an unbroken seal that prevents moisture from es- caping from living spaces and accumulating in insula- tion or cavities in the build- ing's structure. The air- vapour barrier also reduces uncontrolled air change be- tween the house and out- doors. This is an essential ingredient in any strategy that aims for high energy efficiency. Polyethylene __ plastic sheet is the most common material used for air-vapour barriers, though aluminum foil is effective also. It is not easy to install an air-vapour barrier in an existing house. Unless ma- jor renovations are in pro- gress the job is expensive and impractical. There are vapour resistant paints on the market that will improve the resistance of walls to moisture flow by diffusion: and a thorough caulking and sealing job around base- boards, window trim and electrical outlets will cut air flow. In some cases an air- vapour barrier can be in- stalled on an attic floor prior to adding insulation, but this job should be done carefully and with professional guidance. Air-vapour barriers should always be installed on the inside or warm side of insulation. The ideal situa- tion is a complete air- and water-resistant barrier on the inside of a building shell ac- companied by a breathable air barrier on the outside of the insulation to allow any penetrating indoor moisture to escape. One exception to this rule involves the use of moisture barriers. A mois- ture barrier is intended to protect insulation and structural materials from moisture entering from the outside of the building. For example, plastic sheeting is often placed over the below- grade portion of basement walls before framing and in- sulation are installed on the inside. In these situations a thorough sealing job on the inside air-vapour barrier is essential to prevent moisture from being trapped in hidden insulated cavities. Remember that any- thing -- a pipe, electrical wire or duct -- that passes through an air-vapour bar- rier, is a potential trouble spot.
