In the electricity sector, energy conservation through technological and behavioral change is estimated to have a savings potential of 123 million metric tons of carbon per year, which represents 20% of US household direct emissions in the United States. In this article, we investigate the effectiveness of nonprice information strategies to motivate conservation behavior. We introduce environme...

Dynamic voltage scaling (DVS) is a frequently used technique in mobile and embedded systems, aimed at reducing the energy consumption of mobile processors. A key challenge with DVS is to maximize the energy savings while ensuring that applications’ real-time requirements are met. This paper experimentally evaluates the DVS capabilities of a mobile platform based on the XScale PXA255 processor a...

The anticipated explosive growth of pervasive and mobile computing devices that are typically constrained by energy has brought hardware and software techniques for energy conservation into the spotlight. While there have been several studies and proposals for energy conservation for CPUs and peripherals, energy optimization techniques for selective operating mode control of DRAMs have not been...

This paper presents TESLA, an agent-based application for optimizing the energy use in commercial buildings. TESLA’s key insight is that adding flexibility to event/meeting schedules can lead to significant energy savings. TESLA provides two key contributions: (i) three online scheduling algorithms that consider flexibility of people’s preferences for energy-efficient scheduling of incrementall...

There has been extensive research focusing on developing smart environments by integrating data mining techniques into environments that are equipped with sensors and actuators. The ultimate goal is to reduce the energy consumption in buildings while maintaining a maximum comfort level for occupants. However, there are few studies successfully demonstrating energy savings from occupancy behavio...

The energy savings potential of selected low-cost measures related to the simultaneous control of blinds, electric lighting, heating, cooling and ventilation in a single building zone (Integrated Room Automation) was investigated. The analysis was based on a factorial study comprising several thousands, whole-year hourly time step simulations. The largest energy savings potential was found for ...

Recent popularity in smart devices, for example smartphones, has created an increased interest in carrying small devices with limited battery capacity. Unfortunately, smartphones are notorious for consuming energy far too quickly. Although certain advances have been made on the hardware side such as better batteries, the first part of the talk will be focused on improving energy management soft...

In mobile devices, limiting the Graphics Processing Unit’s (GPU’s) energy usage is of great importance to extending battery life. This work shows that significant energy savings can be obtained by reducing the precision of graphics computations, yet maintaining acceptable quality of the final rendered image. In particular, we focus on a portion of a typical graphics processor pipeline—the verte...

The State of California has committed an unprecedented sum of $2.2 billion in ratepayer funds to utility-delivered energy efficiency programs from 2006 through 2008; the State finalized in 2007 the determination of the shared-savings incentive mechanism for the 2006-2008 programs and beyond. This study seeks to examine whether the adopted incentive mechanism would ensure an efficient delivery o...
