Parametric residential heating energy, thermal comfort and CO2 concentration data for an energy-efficient semi-detached house in Ireland

The dataset is a synthetic, simulation-based collection of numerical data representing the energy performance, thermal comfort, and indoor air quality (specifically CO₂ concentration) of a low-energy, naturally ventilated semi-detached residential dwelling in Ireland, an oceanic temperate climate zone. Generated through 45,000 parametric simulations using EnergyPlus and the jEPlus tool, the dataset captures a wide range of building design and operational scenarios for an A-rated semi-detached house, the most prevalent residential archetype in Ireland. It is stored in a comma-separated values (.csv) format and hosted on Mendeley Data, with the data originating from University College Dublin, Ireland. The dataset comprises 19 input parameters and 24 output parameters, detailed as follows:

Input Parameters

Sampled via LHS from Irish EPCs and TUS data:
Window U-value (0.53–3.21 W/m²·K): Glazing heat loss.
Floor U-value (0.06–0.85 W/m²·K): Floor insulation.
Roof U-value (0.06–0.88 W/m²·K): Roof insulation.
Wall U-value (0.12–0.85 W/m²·K): Wall heat loss.
Orientation (0–360°): Solar exposure.
HSPT (18–22°C): Heating setpoint.
Lighting Density (1–6 W/m²): Lighting load.
Occupancy Density (0.0125–0.3289 persons/m²): Occupant load.
Equipment Density (16–24 W/m²): Equipment load.
HVAC Efficiency (0–1): Heating efficiency.
Infiltration (0.35–1.5 ACH): Air leakage.
Metabolic Rate (60–360 W/person): Occupant heat.
Clothing Value (0–1 clo): Thermal insulation.
SHGC (0.1–1): Solar gain factor.
WWR (40–90%): Window area ratio.

Output Parameters

Calculated per simulation:
c0: Heating (kWh/year): Annual heating energy.
c1: Lighting (kWh/year): Annual lighting energy.
c2–c8: Thermal Discomfort (hours/year): Hours outside comfort for kitchen, dining, sitting, bedrooms 1–3, facility.
c9–c15: Setpoint Not Met (hours/year): Unmet heating hours for kitchen, dining, sitting, bedrooms 1–3, facility.
c16–c20: CO₂ > 1000 ppm (hours/year): High CO₂ hours for kitchen, dining, bedrooms 1–3.
c21: EUI (kWh/m²·year): Energy intensity.
c22: Total Site Energy (kWh): Total energy use.
c23: CO₂ Average (hours/year): Mean CO₂ > 1000 ppm hours.
c24–c33: Fanger Index: PMV (-3 to +3) for 10 zones (kitchen, dining, corridor, sitting, top toilet, bedrooms 1–3, top corridor, bath).

We see this dataset as a vital resource for understanding how heating energy, thermal comfort, and CO₂ levels interplay in low-energy, naturally ventilated homes in Ireland. It’s useful for us as architects to optimise building designs, for engineers to refine HVAC and ventilation systems, for policymakers to shape energy-efficient regulations, and for researchers like us to study occupancy impacts on indoor environmental quality.
