Building_eload

Version: 0.4.0

District-level building energy simulation at hourly resolution.

This model was first presented in the research article : https://doi.org/10.1016/j.enbuild.2026.117409

Overview

building_eload runs a two-stage pipeline:

1. Static simulation: annual building-level energy estimates and calibration.
2. Dynamic simulation: hourly electricity load profiles from static outputs.

Main dependency:

• buildingmodel (for static building physics simulation)

Installation

git clone https://git.persee.minesparis.psl.eu/planeterr/building_eload.git
cd building_eload
pip install -e .

If needed by your workflow, also install buildingmodel in editable mode.

Minimal Usage

Tutorials for botyh simulation process are available in : /doc/tutorials

1) Static simulation

import numpy as np
from building_eload.core.static_simulation import StaticParameters, StaticSimulation


district_id = "262320000"
eu = np.arange(0.7, 1.3, 0.05).round(2)
hs = np.arange(16.0, 22.5, 0.5).round(1)
energy_use_parameters = [
    {"actual_heating_set_point": hs[i], "energy_use_factor": eu[i]}
    for i in range(len(hs))
]

params = StaticParameters(
    n_inference=10,
    calibration_year=2023,
    climate_year=None,
    energy_use_parameters=energy_use_parameters,
)

sim = StaticSimulation(district_id=district_id, parameters=params)
results = sim.run()
results.save_results()

2) Dynamic simulation

from building_eload.core.dynamic_simulation import DynamicParameters, DynamicSimulation


district_id = "262320000"
params = DynamicParameters(
    year=2023,
    run_non_residential=True,
    run_again=True,
)

sim = DynamicSimulation.from_files(district_id=district_id, parameters=params)
sim.run()
sim.save_results()
