This video from the Alliance to Save Energy outlines a retrofit project that took place at the residence of the US Ambassador to Belgium. The savings outlined are impressive, including a cut of more than half in electricity usage for lighting. Among the speakers on the video are the Alliance’s president Kateri Callahan as well as representatives of a number of major energy and consumer goods firms.

But the more impressive part of the video is in the project’s broader applicability. The brands that the Alliance used in the residence are largely major global brands, not expensive niche products from inaccessible companies. The key takeaway is that the lessons on energy saving that come from this relatively high-end project can be used in a wide variety of settings to monitor and save electricity.
