Abstract: This application relates to a building energy analysis and management system for measurement and verification of building performance. The system can analyze, optimize, manage, maintain, trouble shoot, and/or modify building systems, such as HVAC systems, in connection with the building energy usage. Measurements may be gathered for one or more HVAC units coupled to pressure independent valves, and sent to one or more Surge Panels that pass data to remote analysis servers, which can receive other system or external data. The analysis servers compare measurements to predicted values and can standardize the predicted values to account for external conditions. The comparison can result in difference values used to generate probable causes and optimization recommendations. The system outputs reports or other data display using a graphical user interface that can be adjusted for an anticipated user.

Abstract: The present invention relates to a rim or hub shield for protecting a rim of a tire from harmful tire cleaning solutions. The rim shield features a round body having a slightly concave contour, an exterior surface and a concave interior surface, and a pair of oval cut-outs around the center of the shield allowing a user to grip the device. The shield includes a pair of pockets for storing cleaning supplies and other accessories. The shield can be placed against the rim using one hand while cleaning can be performed using the other hand. Alternatively, the shield can be securely placed around the rim by securing a protrusion along the periphery of the shield around the rim of the tire.
