Systems validation
Do the heating and ventilation systems trano generates behave as the real ones do? Each case below puts one
system on the same 100 m2 zone (filled cavity walls, insulated roof and slab, 10 m2 of low-e double glazing
facing south, n50 = 3, occupied from 7 to 19 h, heated to 21 degC from 7 to 22 h and 16 degC at night) for one
week of the Uccle weather, and is simulated with Buildings, IDEAS and FastSmoothBuildings. The KPIs are read
from the result files by validation/systems/kpi.py; the band of every KPI and the physical reasoning behind
it are in validation/systems/expected.yaml; pytest -m systems fails when a KPI leaves its band. The tables
are rendered from the last results with python -m validation.systems report --docs.
Heat pump
hp_winter
Air-water heat pump, 4 kW at -8/45 degC, 100 l buffer, heating curve 45 to 30 degC, the coldest week. Week from day 18 of the year.
