Energy savings in Internet have been regarded as a significant technical issue for academic and industrial community. Particularly, access network accounts for more than 70% of the total energy consumption of Internet. As a promising access technique, Fiber-Wireless (FiWi) network not only enables the cost-effective broadband access, but also provides more opportunities for energy savings. Prev...

The objective of this paper is to estimate the potential for electricity savings with the use of daylighting integrated with the artificial lighting system and hybrid ventilation in commercial buildings located in Florianópolis, southern Brazil. Several models were analysed. Two cases were investigated: a reference case, operating only with air-conditioning system and another one with the use o...

Compiler support for power and energy management is effective in reducing power and energy consumption of programs. This work investigates the benefits of optimising sets of programs to reduce overall disk energy. Our validation experiments include physical measurements from two laptop disks. The experiments show that inter-program optimisations have significant energy savings over individually...

This paper relates the potential energy savings to the energy profile of a circuit. These savings are obtained by using gate sizing and supply voltage optimization to minimize energy consumption subject to a delay constraint. The sensitivity of energy to delay is derived from a linear delay model extended to multiple supplies. The optimizations are applied to a range of examples that span typic...

One proposed technique to reduce energy consumption of data centers is thermal-aware job scheduling, i.e. job scheduling that relies on predictive thermal models to select among possible job schedules to minimize its energy needs. This paper investigates, using a more realistic linear cooling model, the energy savings of previously proposed thermal-aware job scheduling algorithms, which assume ...

Title of Document: VARIATIONS ON THE NORMATIVE FEEDBACK MODEL FOR ENERGY EFFICIENT BEHAVIOR IN THE CONTEXT OF MILITARY FAMILY HOUSING Robert M. Young, 2013 Directed By: Dr. Qingbin Cui, Department of Civil and Environmental Engineering In discussions on energy efficiency, the topic often involves the development of a new technology. But models that target human behavior change can also generate...

The purpose of this study was to quantify and contrast the instantaneous segmental and total body energy patterns of rowing a single scull racing shell with rowing a Gjessing (Norway) rowing ergometer (RE), and to contrast energy savings through exchanges of mechanical energy among segments and conversions of energy within segments. Four scullers, two male and two female, were filmed at three s...

■ Abstract We review literature on several types of energy efficiency policies: appliance standards, financial incentive programs, information and voluntary programs, and management of government energy use. For each, we provide a brief synopsis of the relevant programs, along with available existing estimates of energy savings, costs, and cost-effectiveness at a national level. The literature ...
