In this free lecture, Andy Shapiro will ask and answer questions relative to understanding how well a new, small, well-insulated house is performing on energy use and temperature control:
- What do I want to know about this building (or subsystem)?
- What data do I need to answer my questions?
- How do I go about getting that data?
Andy uses the example of a 22’ x 26’ two-story and basement house in Vermont with a single air source heat pump on the first floor. The owner finds she needs an electric heater on the second floor to maintain comfort temperature when working, contrary to design expectations. Andy shows how he uses available electricity usage data and simple instrumentation to look at temperatures in the house, the data he gathers and what he does with that data.
You will see Andy’s answers to the questions above in the particular context of this building. He includes information on measurement equipment, its upsides and downsides, what he learns and how he learns it—data gathered and analysis—including all the bumps along the way!
