Summer forecast: Heat wave returns The retu nI ofihe heat wave means a long, hot sumi "ef ls 'îIznl Monit li oluon. Hoat waves uiade a comeback duning the Summer of 1993, with 41 cities reporting an increase in cooling degree days from Victoria Day through Labour Day. A cooling degree day is defined as the accumulation of degrees which the average daily temperature ils above 65 F (18 C). For example, a mean temperature of 78 F yields 13 cooling degree days. The more cooling degree days, the more energy used to cool our homes and work- places. The cooler, weîîer summers of the early- 1990s con be traced t0 two significant evenîs: the June, 1991 eruption of Mount Pinatubo, in the Philippines, reilected enough sunlight 10 cool the carth by 1 F, and the reappearance of El Nifio, the vasî pool of warm water that devclops every two- t0 seven-years sn the eastern Pacific Ocean off'South America. El Nifio's return in early- 1992, sel off a chain of' atmospheric eenîs that among other things, brought heavy rains 10 Texas and conîribuîed to storms in draughî-plagued Califomia, as well as across the country and mbt the Northeast i n the winter of' 1992-93. Taking mbt account the graduai diminisbing of both the cooling effect of the Mount Pinatubo eruption and tbe disappearance of El Nifio, the satellite data sug- geaIs a global warming trend that, by the laie-1990s, will cause average global bemperatures to exceed the record levels of the late- 1980s. Don't Wait For A Crisis If these findings are correct, now lis an ideal lime for homeowners to consider purchasing a central air con- diîioning system or replacing one that is more than 10 years old. Today's systems are up 10 60 percent more energy efficient than a typical 10- to I 5-year old unit. "No one wanîs to walk in aller a hard day's work to a home that isn'î cool because the air conditioner isn't working properly," says Derrick Marris, director of product marketing, Payne Heating & Cooling. "You should be able to count on being cool and comfortable when you need 10 be."

"Surveys show that while homeown- ers wanî comforî, they also want a syslem that responda 10 peak demands and performs quieîly," Marris adds. Fighting Indoor Air Pollution "Total indoor comfort does not end with the selec- lion of an air condiîioning unit," notes Marris. "In facî, Ibis ls the perfect lime 1e, have a conîractor evaluate your home's indoor air qualiîy, as well as energy effi- ciency." While today's homes are builî or retrotitted 10 maxi- mize energy efftciency, the result con oflen be harmful t0 their inhabitants. Indoor air quality problemrs, mosî commonly associaîed wiîh modem office buildings, are becoming more prevalent as homes are built "tighter" 10 keep worm air from escaping in winîer, and from entering in summer. Pollutanîs are trapped indoors, and the resulîs con be harmnful over lime. 'Me simple answer to Ibis serious problem li 10 open the windows. Buat doing Si) compromises many of the home's energy-saving features. However, there ls good news for concemed homeowners: for the annual cost of operaîing o 30-watt lighîbulb, today's homes can be protecîed against the residential equivalent of "sick building syndrome." A healthy. energy-efficient answer t0 these proh- lems is a heat recovery ventilator. When installed in conjuniction with the heating and cooling system, heat recovery ventilators like Payne's Vent PerfecTm are designed 10 remnove indoor air pollutants and draw fresh, oulside air mbt the home. By recycling heat mbt the fresh air stream and simultaneously exhausîing the stalle, over-humid air fromn the home, Vent Perfect recovers up 10 84 percent of the exiting air's heat. Another solution 10 the indoor air qualiîy question is Payne's elecîronic air cleaner, which effecîively and affordably removes duslt, dirt. smoke, pollen, grease and microorganisms that circulate inside a home.
