Due to increased grid problems caused by renewable energy systems being used realize zero buildings and communities, the importance of sharing self-sufficiency also increased. In this study, performance an energy-sharing community was investigated improve its efficiency self-sufficiency. For a case smart village selected via detailed simulation. thermal for cooling, heating, domestic hot water ...

Within a 53 home monitored sample, long-term energy use of electric resistance clothes dryers was sub-metered. Average measured dryer energy use was 3% of total household energy or 814 kWh/year. Hourly dryer electrical demand profile showed large coincidence with utility summer afternoon peak and significant increases over weekends versus weekdays. After collection of baseline data, electric re...

Much energy is lost through excess air flow in and out of process heating equipment. Energy saving opportunities from managing air flow include minimizing combustion air, preheating combustion air, minimizing ventilation air, and reconfiguring openings to reduce leakage. This paper identifies these opportunities and presents methods to quantify potential energy savings from implementing these e...

The move to a pervasive computing environment, with the increasing use of laptops, netbooks, smartphones and tablets, means that we are more reliant on wireless networking and batteries for our daily computational needs. Specifically, this includes applications which have sensitive data that must be securely communicated over VPNs. However, the use of VPNs and mobile, wireless computing creates...

The Data Timed Sending (DTS) protocol contributes to the energy savings in Wireless Sensor Networks (WSNs) and prolongs the sensor nodes’ battery lifetime. DTS saves energy by transmitting short packets, without data payload, from the sensor nodes to the base station or the cluster head according to the Time Division Multiple Access (TDMA) scheduling. Placing the short packets into appropriate ...

Background: Rapidly increasing residential electricity demand has made raising energy efficiency an important policy issue in controlling electricity demand. Methods: This study uses a stochastic frontier model to estimate the residential electricity demand function and analyse electricity energy efficiency levels and their determinants using regional data on Japan. Results: The results confirm...

Seeking cost reduction and energy savings in water supply by improving the operation of pumps is both an obvious as well as a very efficient possibility to consider. Without making changes to the basic elements of a water supply system, remarkable reductions in operation costs can be achieved by optimising the pump scheduling (PS) problem. The UK Water Research Centre (WRC) [1985] estimates the...

We present an algorithmic noise-tolerance (ANT) technique for designing low-power DSP systems. The proposed technique achieves substantial energy savings via voltage overscaling, whereby the supply voltage is scaled beyond the minimum supply voltage Vdd−crit at which the architecture operates correctly for a given throughput specification. The resulting input-dependent soft errors are corrected...
