A linear-fit method of rating residential-type air conditioning systems was evaluated based on performance predictions and laboratory testing of one two-speed matched system and two mixed systems (matched two-speed condensing unit, matched indoor coil

This is the April 2010 edition of energy price indices and discount factors for performing life-cycle cost analyses of energy and water conservation and renewable energy projects in federal facilities. It will be effective from April 1, 2010 to March 31
This paper quantifies the influence of Al2O3 nanoparticles on the pool boiling performance of R134a/polyolester mixtures on a roughened, horizontal, flat surface. Nanofluids are liquids that contain dispersed nano-size particles. A lubricant based
The 60 mV/dec limit for subthreshold swing at 300K is generally considered a fundamental limit that cannot be defeated. The physical origin of this limit is revisited in this paper and the fact that this limit is in part determined by the density-ofstates
The benefits of energy conserving approaches in buildings are often not apparent to building occupants because of the insufficient feedback provided regarding energy consumption. A review of the literature suggests that energy feedback devices can provide
Building energy efficiency has become a top priority due to the recent energy price spikes and increasing concern regarding climate change. It is easier and less costly to increase energy efficiency in new buildings than in existing buildings, making new

This paper presents the results of initial work in developing an ontology for improving information exchange and automation in building system commissioning practices. In our previous research dealing with the derivation of product models from building
Building energy efficiency has become a top priority due to the recent energy price spikes and increasing concern regarding climate change. New buildings are the easiest and least costly in which to increase energy efficiency, making new construction an
The objective of this research was to acquire heating mode experimental data for a residential heat pump needed for the development of a FDD methodology. Within this project, a heat pump equipped with a thermostatic expansion valve (TXV) was tested in the
We examined the air flow distribution through a residential indoor air conditioning heat exchanger. The test heat exchanger was a finned tube, A-shaped coil outfitted with a condensation collection pan required for a horizontal installation configuration
This is the 2009 edition of energy price indices and discount factors for performing life-cycle cost analyses of energy and water conservation and renewable energy projects in federal facilities. It will be effective from April 1, 2009 to March 31, 2010
