1 Smart Summer Savings Calculatins and Surces Air cnditining can accunt fr up t 50 per cent f yur summer electricity bill. Try t use it nly when necessary t remain cmfrtable. As much as pssible, use it during Off-Peak hurs. Use the fllwing tips fr further savings. Install and use a prgrammable thermstat. Then yu can autmatically manage yur air cnditining. Yur energy savings will easily pay fr the cst f the thermstat in the first year. Run yur air cnditiner just a little warmer and save up t $17 (average 3.9% increase ver last year) a mnth. Set yur thermstat at 25 C fr eight hurs a day. Then shift t 22 C during Off-Peak hurs t save. When yu turn n air cnditining, d nt switch yur thermstat t a clder setting than yu need. It will nt cl the rm any faster. When yu re nt at hme, turn yur air cnditiner ff, but keep yur ventilatin fans running t circulate the cl air. Yu can prgram the thermstat t turn n just befre yu get hme. Reduce heat gain in yur hme. Drawing blinds r shades during the day n windws facing suth r west can reduce yur air cnditining csts by up t $12 (average 3.9% increase ver last year) a mnth. Think fans befre air cnditining. A ceiling fan can save yu abut $19 (average 3.9% increase ver last year) a mnth n cling csts. Set yur air cnditiner 5 C higher, use an ENERGY STAR qualified ceiling fan and yu culd reduce cling csts by up t 30 per cent. Studies have shwn that during spring and fall, the cst t perate a fan is apprximately $1.60 (average 3.9% increase ver last year) per mnth vs. $21 (average 3.9% increase ver last year) per mnth fr air cnditiners. Try t install yur air cnditiner in a shaded area. An air cnditiner that is expsed t direct sunlight will cnsume five per cent mre energy than ne that is shaded. Prper maintenance f yur air cnditiner can increase its efficiency by abut five per cent. Yu can clean the utside cmpressr yurself with a hse, remving debris that impedes airflw. On average, the savings will be $4 (average 3.9% increase ver last year) a mnth during the summer. Shpping fr an air cnditiner? Pay attentin t the Energy Efficient Rati (EER). The higher the EER f the unit, the lwer the cling csts. Replacing yur ld air cnditiner (EER f 10) with a new unit (EER f 14) will typically save $26 (4.7% increase ver last year) a mnth during the summer.

Fr easy tclean lads, use the light r shrt cycle. Always wait until the dishwasher is full befre yu run it If yu have an electric stve and ven, trying shifting their use t Off-Peak. When pssible, use a micrwave r taster ven. A micrwave uses up t 50 per cent less electricity than an electric stve. Use lids n yur pts while cking and reduce energy cnsumptin by up t 14 per cent If yu re lking fr a new majr appliance, read the EnerGuide label and cmparisn-shp fr the mst energy-efficient mdel. The lwer the kwh rating, the better the efficiency. Lk fr ENERGY STAR qualified mdels. Did yu knw an ENERGY STAR fridge is 20 per cent mre efficient than a nn-qualified mdel? If yu have an electric ht water tank, yur water heating csts can be a substantial prtin f yur ttal. Use these tips t reduce yur csts. Have a qualified persn check the temperature f yur ht water tank. The recmmended setting is 49 C 60 C (140 F). Any higher is prbably wasteful and may prduce water that is t ht at the tap. Wrap yur electric water heater with an insulating blanket t save abut $2.30 per mnth. Be sure it s CSA certified. (average 3.9% increase ver last year)

4 Average standby lsses fr a dmestic ht water tank are 0.7 kwh per day.21 kwh per mnth 21 kwh per mnth * 10.7 per kwh-average (average 3.9% increase ver last year) Insulate at least the first three feet f pipe leading t and frm the ht water tank with tape wrap r fam pipe tubing. Dn t wrap plastic pipes the extra warmth might sften them Fix leaky taps. A tap dripping at ne drp per secnd wastes 800 litres f water per mnth. Usually the cause is just a wrn-ut washer, which is cheap and easy t replace Quick shwers use less ht water than baths. A typical bath uses abut 75 litres f ht water, while a 5- minute shwer with an energy-efficient shwerhead uses less than half f that. Abut 25 per cent f all husehld ht water is used fr clthes washing. Use cld-water washing and rinsing wherever pssible. Cld water rinsing can save yu enugh energy fr abut 100 ht baths r 220 shwers per year. When yu d use ht water washing, be sure t set the water level t match the lad. An energy-efficient shwerhead can reduce yur ht water use by up t 30 per cent. In ne year, yu can save ver 28,000 litres f water. Yu ll still get brisk shwers, and save a significant amunt n yur electricity bill. Install faucet aeratrs n yur sink faucets t lwer water flw. Aeratrs mix air int the water flw and reduce water cnsumptin by per cent per tap. Little things add up t bigger savings. In many cases yu nly need t d smething nce and the savings keep cming. Fr example, as yur incandescent bulbs burn ut, replace them with cmpact flurescents. It s an easy way t make the transitin. Save $4 a mnth by switching frm incandescent (average 3.9% increase ver last year) t cmpact flurescent lights (based n eight lights, five hurs per day). CFLs last up t 10 times lnger and can use up t 75 per cent less electricity. Yu can replace an incandescent 100W light bulb with an 18W 23W cmpact flurescent and get the same amunt f light. s

Eliminate drafts in yur hme air leakage arund windws, drs, vents and electrical utlets can accunt fr as much as 25 per cent f yur ttal heating csts. That als applies t letting cl air ut. Caulk and weather-strip windws, drs, dryer and ther vents, and install insulated plates n electrical utlets.

6 Increase the amunt f insulatin in yur hme t keep it warmer in the winter and cler in the summer. The attic and basement represent as much as per cent f yur hme s verall heating and cling lsses. Make sure yu add attic vents s ht air can escape Many businesses can apply the same mney-saving tips that apply t hmes. Hwever, energyefficient lighting likely plays a bigger rle, as des the wise use f air cnditining. In the summer, set yur thermstat t 25 C instead f the lw 20s. Add a prtable r ceiling fan t help cling. Typically a small business can achieve mnthly savings f $21 t $78 with these measures. Relax yur dress cde t help keep emplyees cmfrtable. (average 3.9% increase ver last year) Dn t leave the frnt dr pen when air cnditining. This csts the average small business $83 t $260 a mnth.. (average 3.9% increase ver last year) Replace standard incandescent light bulbs with energy-efficient cmpact flurescent lamps. Yu ll get the same lighting level at a fractin f the cst. andescent_bulbs_with_cfls.html Replace T12 flurescent tubes with mre energy-efficient T8 tubes t save up t 25 per cent Add reflectrs n flurescent tube fixtures t increase the effectiveness f lighting, which ften allws fr lwer wattage and/r fewer bulbs. Remve light bulbs in areas with excess lighting levels, such as near windws, in hallways and in areas with n furniture. Replace traditinal EXIT signs with newer LED signs. By law, EXIT signs must be lit whenever a building is ccupied, s they are ften n 24 hurs a day. While mre expensive t purchase, LED bulbs can last up t 10 years, which can mean lwer csts ver the lng term. r_exit_signs.html Install ccupancy sensrs and dimmers in break rms, restrms and cnference rms t reduce lighting csts by up t per cent.

7 Keep cmputers n standby. On average, cmputers are nly used 10 per cent f the time they are turned n Many electrnic items such as TVs, cmputers, phtcpiers and ther equipment cntinue t cnsume small amunts f electricity, even when turned ff. Try plugging these items int a pwer bar with a switch, s yu can easily turn them ff when they are nt in use Replace ld cmputer systems and mnitrs with ENERGY STAR qualified mdels t reduce energy use by up t 75 per cent. Fr example, a flat-panel LCD mnitr cnsumes less than half the energy f a CRT mnitr. Cnsider using ink-jet printers they require less energy than laser printers. If yu have a large walk-in refrigeratr, cnsider installing a humidity cntrl system t increase its temperature by tw t fur degrees. Since walk-ins usually stre fresh fd r meat, humidity and temperature must be kept at the prper levels t preserve fd quality. Check with yur appliance supplier t ensure the ptimum levels. If yu have a cmpressed air system, check it fr leaks. A small leak f nly 0.8 millimetres can waste up t $104 f energy per year. (average 3.9% increase ver last year)
