States generally allow a broad range of end-use efficiency programs to count toward energy efficiency requirements, including home weatherization; light bulb and appliance replacement; improvements in industrial heating, ventilation, and air conditioning systems; and many others. Measurement and ...
Efficiency TestsGELGMMWe evaluate the use of Generalized Empirical Likelihood (GEL) estimators in port- folio efficiency tests for asset pricing models in the presence of conditional information. Estimators from GEL family present some optimal statistical properties, such as robustness to misspecification ...
All elements leaving with off-gas or silica fume were treated as elements, except sulfur, which was assumed to oxidize during combustion to SO2[51]. Fume filter efficiency for silica recovery was set to 99.96% [52]. The amount of cooling water for the furnace and the amount of air let i...
The passengers’ overall satisfaction appeared to be influenced by the perception of air conditioning and heating efficiency/control of environmental conditions within the airport, the skills and usefulness of the staff, the tidiness of the terminal, the availability, quality and prices of bars and ...

In terms of (a), some appliances, such as air conditioning, are mainly used when the temperature increases above the comfort level or decreases significantly, while water heater systems require higher consumption when the temperature is low (possibly being part of the year disconnected, when ...

The growth of the variable of change in global temperature is influenced by an increase in emissions of nitrous oxide, an increase in waste generated from electricity, gas, steam and air conditioning as well as an increase in waste generated by households. The volume of methane and greenhouse ...
