This graph shows my home's cold water pressure, supplied of course by the City, over the course of 24 hours. The pressure is sampled many times a second for several minutes. The minimum value and maximum value that the pressure reached during that sampling interval is graphed below.

This shows the activity of the five radiant floor heating zones in my house. When a zone is on (heating), a colored symbol is plotted on the graph representing that zone. Two zones are lumped together in this graph, the master bedroom and the core of the house are shown as "rest of house".
To improve my home's thermal efficiency I have blocked its foundation vents. However, those vents are needed to control humidity, to avoid mold. The humidity can get too high, for example, if there is a plumbing leak or if ground water gets under the house. My approach is to continuously monitor the humidity and take corrective action if necessary. This both saves energy, by allowing me to safely block the foundation vents, and gives me an early indication of trouble.
