FREE OPEN STUDIO DOWNLOAD LATEST REPORT Department of Energy and NREL \ OPEN STUDIO
The Energy Department created OpenStudio, a software kit and suite of advanced energy modeling tools. Engineers, architects, and others can explore the most efficient improvements available for commercial buildings with this free application suite. Through its user-friendly interface, design teams can use OpenStudio to understand the cost implications of their specific plans.One of the key components of this system is its ability to tap into the Energy Departments advanced whole-building energy modeling program, EnergyPlus. Designers can draw the building in detail using site photos and other inputs to get an accurate representation of the building. OpenStudio then converts the information into data that EnergyPlus uses to help designers understand the impact their design choices are having on cost, energy efficiency, and code compliance. The plug-in also speeds up the modeling process, which is otherwise complex and time consuming.

Executive SummaryA demonstration of induction lighting was conducted at the City Station parking garage in Morrow, GA. Baseline measurements of fixture power consumption and light intensity in a designated control space with the current 100-watt metal halide fixtures were conducted on September 30, 2010. The metal halide fixtures were replaced with induction during October, and the measurements were redone on November 10, 2010.With the replacement induction fixtures, the fixture power consumption decreased by a minimum of 43 percent. The test results indicate induction lighting is more efficient in this application.A second benefit found with induction lighting is increased uniformity of light distribution in the space. Measurements of light intensity in the space evaluated found the ratio of the highest to the lowest as well as the standard deviation to be less for induction lighting. While this is not related to fixture efficiency, it does mean the quality of lighting may be improved by converting to induction fixtures.Results, ConclusionsThe lighting demonstration of the City Station parking garage provided a valid field comparison between metal halide and induction lighting. While the measured light intensity was slightly less with induction lamps, the input power was reduced by 43 percent. This indicates that the induction lamps are more efficient than the metal halide. IEstimated energy savings = 1 – (42.3/75) = 43.6% This agrees closely with the 43% measured savings.
