Are intelligent agents the key to optimizing building HVAC system performance?

August 10, 2012
Author(s)
George E. Kelly, Steven T. Bushby
This paper describes the development and implementation of a simulation testbed used to study the concept of employing intelligent agents to optimize the performance of building Heating, Ventilating, and Air Conditioning (HVAC) systems. One day simulated

VISCOSITY AND DENSITY OF CuO NANOLUBRICANT

June 14, 2012
Author(s)
Mark A. Kedzierski
This paper presents liquid kinematic viscosity and density measurements of a synthetic polyolester based copper (II) oxide (CuO) nanoparticle dispersion (nanolubricant) at atmospheric pressure for a temperature range from approximately 288 K to 318 K. The

Battery Discharge Characteristics of Wireless Sensors in Building Applications

April 11, 2012
Author(s)
Wenqi Guo, William M. Healy, Mengchu Zhou
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

OASIS Collaborative Energy Standards, Facilities, and ZigBee Smart Energy

February 1, 2012
Author(s)
David G. Holmberg, William Cox, Don Sturek
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

Annex 47 Report 1: Commissioning Overview

December 1, 2011
Author(s)
Chlo? Legris, Daniel Choiniere, Natascha S. Milesi-Ferretti
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,

An Information Model Standard for Facility Integration With A Smart Grid

November 1, 2011
Author(s)
Steven T. Bushby
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

Using the BACnet Data Source v1.7

October 20, 2011
Author(s)
Michael A. Galler
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

Strategy and Modeling for Building DR Optimization

October 17, 2011
Author(s)
Richard Lau, Sami Ayyorgun, Siun Chuon Mau, Archan Misra, David Holmberg, Steven T. Bushby
While it is well recognized that renewable microgrid generation and intelligent storage can significantly reduce a building's need for grid power and its peak loading, there is currently no sound and generalized approach to combine these two technologies

Alternative Cooling Technology Options

August 21, 2011
Author(s)
J S. Brown, Piotr A. Domanski
This paper considers the alternative cooling technologies studied by Fisher et al. (1994) and assesses their current potential to compete with or to replace vapor compression refrigeration technology for space cooling and near-room temperature

VISCOSITY AND DENSITY OF ALUMINUM OXIDE NANOLUBRICANT

August 17, 2011
Author(s)
Mark A. Kedzierski
This paper presents liquid kinematic viscosity and density measurements of a synthetic polyolester-based aluminum oxide (Al2O3) nanoparticle dispersion (nanolubricant) at atmospheric pressure over the temperature range 288 K to 318 K. The polyolester was a

Consumer Use of Dishwashers, Clothes Washers, and Dryers: Data Needs and Availability

March 21, 2011
Author(s)
Christopher Iglehart, Natascha S. Milesi-Ferretti, Michael Galler
NIST provides technical support to the DOE in developing test procedures for a variety of residential appliances. As part of this process, DOE seeks representative consumer use data to establish test procedures that are representative of real world use
