Summarized heating design loads and Manual J inputs for the 4 dwelling units:

  • Very low heating design temperature (~-17F)
  • Some combination of:
    • High ACH50
    • Uninsulated floors/ceiling/walls

Thus heating design load components are quite large, contributing to a large system size. In reality, it's likely uncommon for ND homes to have such housing characteristics.

@rajeee to send additional datapoints that are more typical of a realistic dwelling unit in ND. This will help to understand our target heating design loads.

@joseph-robertson to check what happens when we manually adjust extreme:

  • ACH50; decrease by, e.g., 30%
  • Insulation levels; incrementally increase to, e.g., R-11, R-13, etc.

How much does the previous contribute to the decrease in heating design loads? Idea: use a precomputed buildstock csv file with manual adjustments in a parametric analysis?

Comment on lines +85 to +92
if building_ids.empty?
buildstock_csv = CSV.read(des, headers: true)
datapoints = buildstock_csv['Building'].map { |x| Integer(x) }
n_datapoints = datapoints.size
else
datapoints = building_ids
n_datapoints = `wc -l "#{des}"`.strip.split(' ')[0].to_i - 1
end

Should this be salvaged from this PR? I'm having trouble remembering why I added this. Is this to support running specific datapoint IDs with an already-downselected precomputed buildstock csv?
