TRNSYS Simulation Model for a Net-Zero Energy Building with GSHP

A TRNSYS building energy simulation model for a Net-Zero Energy Building (NZEB) on the NIST campus in Gaithersburg, Maryland, USA. The model integrates a ground-source heat pump, heat pump water heater, energy recovery ventilator, dehumidifier, and photovoltaic array. It was used in a 2024 journal paper published in Energy Conversion and Management.

Use Cases

• Calibrate and validate building energy models by comparing simulated energy consumption outputs against measured performance data.
• Analyze the integrated performance of the ground-source heat pump and photovoltaic array for HVAC and domestic hot water loads.
• Study occupant comfort metrics generated by the simulation under various thermal load conditions.
• Investigate the contribution of the energy recovery ventilator and whole-house dehumidifier to overall building energy balance.

Strengths

• Model developed for a real-world Net-Zero Energy Building located on the NIST campus, providing a validated case study.
• Integrates multiple key building systems including a two-capacity ground-source heat pump and a photovoltaic array.
• Peer-reviewed model utilized in a 2024 journal article published in Energy Conversion and Management.

Limitations

• The dataset is a simulation model, not measured empirical data; results are dependent on model assumptions and inputs.
• Specific model outputs (rows/columns) and file sizes are not documented in the provided metadata.
• Geographic scope is limited to a single building in Gaithersburg, Maryland, USA.
