People and energy efficiency

Subscriber, Lyndon Than, wrote to say, "This started out as a Passive House, with insulation values thus: R50 basement, R75 walls, R110 Roof, and German PH windows. During construction, we decided to install an 11.2kW PV array on the roof, which was designed to accept it only in future years. The building now generates about three times the heating energy needed in a year, even at a COP of just 1. Of course, there are other loads, DHW, cooling, appliances, etc. Overall, we are probably net zero, quite likely net positive, depending on how many people occupy the building. I'm finally about to submit the permit application for the heating system - including a seasonal storage component." Here's the link to more. And, Lyndon, thanks for sharing with us! 

Or so says the commercial, but that's not the case at this U.S. Air Force base in Sweden where they've been drinking a special blend made from Hydronica beans. I suppose when you're tapping a pipe for a coffee machine, one pipe is as good as the next. I'm just happy there wasn't a sewage line nearby. That would have lent new meaning to the question, "One lump or two?"
