It's really, really hard to understand a heating system under construction. Everyone keeps leaving doors open - access, fumes, often a lack of the doors themselves....Then painters come in and crank up the heat to make the paint dry quicker. Often it's the owners who really shake down the hvac system. And even then, it's not until the first hot or cold snap that one has any idea what the home is like.
We are looking at over 1 million data points a day - light levels outside, inside, solar energy, network, etc. The insight is gained by correlating data from disimilar systems - security shows doors open - maybe an open window is causing a draft, not a malfunction.
Here is a view into a home running Ambleside's systems. What might normally take 3-4 months to understand got compressed into the first two weeks.
