What 'Hybrid' Means for Cooling
By Paul Valenta, LEED AP; CALMAC Manufacturing Corp.; Fair Lawn, N.J.
The HVAC industry can learn a lot from dual-energy hybrid-car designs. Looking at the numbers, it quickly becomes apparent why manufacturers promote hybrid vehicles and why they are becoming increasingly popular. Hybrid cars provide performance similar to or greater than standard designs while being more fuel-efficient. Consumers get V-6 power with four-cylinder fuel economy. Along with efficiency greater than that of conventionally powered vehicles comes the added benefits of lower operating costs and reduced emissions for smaller carbon footprints. Of course, horsepower and miles per gallon are not the whole story. As with buildings, first cost, maintenance, and overall life-cycle value should be part of the analysis as well. [MORE]
