Automatically Detecting Faulty Regulation in HVAC Controls

May 1, 2013
Author(s)
Daniel A. Veronica
A new method is introduced to automatically detect faulty regulation of temperatures, pressures, and flow rates within the heating, ventilating, and air-conditioning (HVAC) systems and equipment of buildings by using digital data typically available from

Towards Demand Response Measurement and Verification Standards

May 1, 2013
Author(s)
David G. Holmberg, David Hardin, Ed Koch
The value and impact of demand response (DR) at grid-scale depends upon the widespread and active participation of a diverse customer base. The level of participation by customers is impacted by financial compensation and return-on-investment. The role of

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,

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
