retrofit_cost_model — retrofit_cost

Building fabric + ventilation retrofit upgrade cost bute excluding tech such as solar PV or Heat Pumps

retrofit_cost_model(
  hli_old,
  hli_new,
  house_type,
  storeys,
  region = "Dublin",
  floor_area = 100,
  params
)

Arguments

hli_old: hli before upgrade
hli_new: hli after upgrade
house_type: house type
storeys: number of storeys
region: region
floor_area: floor area (m2)
params: current parameters

Value

euros

Details

The default and possibly the most plausible cost model, based on HLI to exclude effects of heating technology efficiency.

Economies of scale currently use a \(area^\frac{2}{3}\) scaling law.
