A building energy geek gut-renovated a small house. Learn about the decisions made, and consequences thereof; about choices of construction assemblies, materials, windows and doors, and mechanical equipment. Successive blower door test data will illustrate how the building was tightened to exceed the Passive House standard. Detailed energy use data will be presented, and performance data of the solar electric system, heat pump, heat recovery ventilator, and heat pump water heater will be presented, and will be compared to the energy model. Lessons learned, opinions, and some less-than-obvious observations about various aspects of the project will be shared. As always, both mistakes and successes will be cheerfully presented, and there will be plenty of time for discussion.
