Abstract: Analyzing energy savings for a building includes receiving historical energy usage and weather data for a building, a set of operations parameters describing building operations and a set of building system parameters describing building systems. A baseline configuration is submitted to a first energy consumption simulation to determine a baseline energy usage profile A calibrated configuration is determined from the baseline configuration and the historical energy usage. An energy usage aberration is identified in the current year. The calibrated energy usage profile is adjusted to account for it. The difference between actual energy usage for the current year and the adjusted calibrated energy usage profile is an accurate measure of savings.

Abstract: A portable safety anchor for use in an aperture with side jambs such as a door or window as a tie off for a safety line. The anchor has a pair of clamps mounted on a bar longer than the aperture is wide. The clamps are T-shaped with a stem and a cross arm. The stem is adapted for contact with a first side of the wall and the cross arm has a toe and a heel. The toe is adapted for contact with the side jamb and the heel is adapted to extend beyond the side jamb on the first side of the wall. The heel has an aperture through which the bar passes. Means are provided for securing the clamps on the bar with the toes in frictional contact with the side jamb and the stem in frictional contact with the first side of the wall. A safety line is tied from the toe of one or both of the clamps such that a force applied to the safety line on the second side of the wall is transferred to the first side of the wall by the clamps.
