Sensor nodes in wireless networks often use batteries as their source of energy, but replacing or recharging exhausted batteries in a deployed network can be difficult and costly. Therefore, prolonging battery life becomes a principal objective in the
The enterprise integration-style interfaces and information models in the Organization for the Advancement of Structured Information Systems (OASIS) collaborative energy standards are designed to address information exchange across the smart grid. This

This report summarizes part of the work of IEA-ECBCS Annex 47 Cost-Effective Commissioning of Existing and Low Energy Buildings. It is based on the research findings from the participating countries. The publication is an official Annex report. Report 1,
This paper quantifies the influence of Al2O3 nanoparticles on the pool boiling performance of R134a/polyolester mixtures on a Turbo-BII-HP boiling surface. An Al2O3 nanolubricant (a lubricant containing dispersed nano-size particles) was made by suspending
The National Electrical Manufacturer's Association (NEMA) and the American Society of Heating Refrigerating, and Air-Conditioning Engineers (ASHRAE) are working to cooperatively develop a national Facility Smart Grid Information Model standard. This
The role of buildings in the electric grid is steadily being transformed to that of active participant in managing the grid, serving as a key player in maintaining grid reliability. The necessity for this transformation is based on three factors: grid
A study was conducted to evaluate the potential for using a linear relationship between the power input to a residential water heater and the output of thermal energy in hot water for rating the units energy efficiency. This approach has the potential for

This paper discusses the issue of standby power in the Department of Energys (DOE) residential appliance test procedures. Section 1 introduces DOEs legislative mandate, briefly discusses the rise of standby power in white products, and gives a sense of
The BACnet Data Source (BDS) was developed to be used as a component of the Virtual Cybernetic Building Testbed (VCBT) (1), in conjunction with work on various Fault Detection and Diagnostics (FDD) (2) and Building Commissioning (Cx) tools. The VCBT uses
