Features for a Modern Strain-Gage Balance Data Analysis Software Tool

Required, recommended, and optional features are discussed that benefit preparation and evaluation of the load prediction equations in a strain-gage balance data analysis tool. First, milestones in the evolution of load prediction methods are reviewed so that suggested features can be put into a historical context. Afterwards, independent and dependent variable choices for the balance data analysis are discussed. Then, it is illustrated how three different metrics may be used for the identification of the root cause of an unwanted divergence of the load iterations that may be observed during an iterative load prediction. Finally, a list of features is provided to guide software development efforts.

DOE Zero Energy Ready Home Case Study: Montlake Modern - Seattle, Washington

This case study describes a DOE Zero Energy Ready Home in Seattle, WA, that scored HERS 42 without PV and a -1 with PV. This 3,192 ft2 custom home has 6-inch SIP walls, a 12-inch SIP roof, an R-28 ICF-insulated foundation slab edge with R-20 rigid foam under the slab; an air-to-water heat pump plus radiant floor heat; 100% LED lighting; filtered-fan-powered fresh air intake; triple-pane windows, 9.7 kWh PV for electric car charging station.
