My esteemed UK colleague Vilnis Vesma has written a series of smart articles that explains the often hidden value of measuring, monitoring and targeting of energy consumption. For the fun of it he arranged the series in alphabetic order. These short posts are written in plain English and contain tons of common sense based [...]

All claims like 'we always keep this operational schedule', 'compressor/boiler/light is off on weekend' or 'current never exceeds X Amp', all of them have exactly zero value to energy [...]

Too often the process ends with meters too. However costly, this result is predictable. I will explain why on an example of [...]
