Abstract

From the research that has been conducted on energy audits in buildings PT. X, to know the profile of energy use and energy savings opportunities, so it can be more efficient and save costs. From the initial energy audit have been implemented acquired Energy Consumption Intensity (IKE) to the total area is still under IKE standards for office buildings. For air-conditioned room is not air conditioned and acquired Energy Consumption Intensity (IKE) is low so as very efficient. By replacing energy-efficient appliances, then there is a chance of saving energy

Abstract

In the measurement process on a machine tool alignment required an alignment as the reference standard.In this case the rod straightener is a measurement tool that is commonly used in metrology laboratories. Inplanning and the alignment rod calibration followed standard JIS B7514, which is described in the standardspecification of the alignment rod which include dimensions, quality and tolerance limits. From the results ofthe calibration are performed on the alignment rod has a classification according to JIS B7514 standardclass (grade) B. Thus the alignment rod can only be used for testing machine tools with high level ofaccuracy that is not high (conventional).
