Slide 10

Efficiency Data Model numbers were coordinated to databases of machine efficiencies CEC, ARI, AHAM, and so on. Once coordinated, the relating effectiveness was appointed to the coordinated machine Matching rates changed extraordinarily by apparatus sort and age.

Slide 11

Primary Cooling Systems Saturation: Over half (53%) of all homes have some sort of cooling framework System Type: Increase in the immersion of focal frameworks, and a diminishing in room/space molding frameworks from 2000 Size: The most well-known focal ventilation system size is the 4-ton class (23%), and the following most regular size is the 3 ton classification (22%). More than 80% are in the vicinity of 3 and 5 tons Efficiency: Of the 257 focal frameworks reviewed, 164 units were coordinated to a productivity database for deciding the SEER. The outcomes propose that focal ventilation system effectiveness has just marginally expanded in the most recent five years.

Slide 12

Primary Heating Systems Saturation: The review comes about demonstrate that 84% of homes make them warm framework, 13% have two frameworks, and 3% have 3 frameworks or more System Type: The most well-known warming framework sort are focal framework constrained air heaters (63%), trailed by divider unit frameworks (13%) Fuel: Single family segregated homes are a great deal more prone to be warmed utilizing characteristic gas, while condos will probably be warmed by electric frameworks Efficiency: The normal Annual Fuel Utilization Efficiency (AFUE) for gas focal warming frameworks is 80.6, contrasted with 72.2 for space frameworks

Slide 13

HVAC Average Age Comparison of HVAC framework age in the vicinity of 2000 and 2005 Across the board diminishment in the normal time of HVAC frameworks

Slide 14

Comparison of SEER Rated Central Cooling Equipment Comparison of AFUE Rated Heating Equipment HVAC Efficiency Trends Across the load up change in the effectiveness of HVAC frameworks

Slide 15

Primary Refrigerator/Freezers Saturation: 19% of homes have a 2 nd cooler Type: Standard sort units have lost piece of the overall industry, while one next to the other units have picked up piece of the overall industry Size (Cubic Ft): Age:

Slide 16

Refrigerator/Freezer Efficiency Unit Energy Consumption (UEC): A 21% normal vitality use lessening was seen from 2000 to 2005 for essential iceboxes. These empowering results are likely because of new government vitality gauges and utility refund and reusing programs. Vitality STAR : 7% of every single essential cooler qualify with the 2004 ENERGY STAR measures 23% of all fridges meet or surpass the 2001 ENERGY STAR principles (1% in 2000)

Slide 17

Self Standing Freezers Saturation: Nearly 19% of homes have a self-standing cooler for nourishment stockpiling. Sort: Age: The general normal time of coolers has diminished from 14 years to 12 years from 2000 to 2005 Consumption: 16% of coolers utilize less vitality than the 2001 government cooler measures, contrasted with 2000 when 9% of coolers devoured less vitality than the 1993 elected guidelines. Estimate:

Slide 18

Clothes Washers Saturation: 82% of all homes have a garments washer. Washers are slightest basic in flat structures, where around 35% of individual abiding units have a clothes washer. Garments Washer Type: Energy Factor: Age: The normal clothes washer age is 6.7 years of age, contrasted with 2000 when the normal age was 7.4 years.

Slide 19

Clothes Dryers Saturation: 80% of homes have a garments dryer, firmly coordinating the immersion of clothes washers Age: Average age is 7.6 years, contrasted with 2000 when the normal age was 8.4 years. Fuel sort:

Slide 20

System Type: The most widely recognized framework sorts are gas stockpiling Efficiency: Standard: National Appliance Energy Conservation Act Standards (NAECA), actualized in 2004. Fuel Type: Age: The normal period of water warmers has dropped, from 9 years of age in 2000 to 7 years of age right now Water Heaters

Slide 21

Dishwashers Saturation: Just under 70% of homes have a dishwasher Age: the normal time of dishwashers is presently assessed to be 7 years of age, down from 9 years in 2000 Efficiency: The normal EF for is more prominent than the ebb and flow government vitality standard, however not as much as the base ENERGY STAR capability

Slide 22

Appliance and Equipment Age Trends An outstanding pattern is happening in the normal age and effectiveness of apparatuses and hardware Example - 2005 discoveries uncover that in 2005 optional fridges are about an indistinguishable age from essential iceboxes were in 2000
