PHPP2E+: EMPLOYING DYNAMIC BUILDING SIMULATION WHILE PURSUING PASSIVE HOUSE CERTIFICATION

 

Abstract:
The building sector alone accounts for around 40% of the global GHG emissions, and aiming to decrease this percentage, various organizations are trying to address the energy load of buildings. European Passive Houses are characterized mainly by construction concepts that can greatly reduce the overall energy usage. During the Passive House certification process, modelers must utilize the Passive House Planning Package (PHPP), a steady-state monthly energy balance tool provided by the Passivhaus Institut (PHI) to verify the performance of the building according to the certification criteria, but nowadays due to climate change and the improvement of hourly dynamic simulations, more detailed analysis of the thermal processes within and around the building are also desired by many practitioners to better understand the indoor environment during the design process.

 

The aim of this thesis is to 1) create a framework to facilitate the conversion of inputs of the PHPP into EnergyPlus, allowing for an easy and quick method of utilizing hourly dynamic building simulations and performing a more detailed analysis while pursuing Passive House certification; 2) investigate the difference in the results reported by the PHPP and by commonly utilized dynamic simulations tools, such as EnergyPlus, and 3) examine how different airflow modeling approaches in dynamic building simulation, such as the standalone BEM, Airflow Network Model (AFN), or Computational Fluid Dynamics (CFD) can affect the results of the simulation results in terms of overheating in Passive Houses. All dynamic simulations will be evaluated using Honeybee as a front-end interface for EnergyPlus, while relying on Rhino3D’s Grasshopper Phyton integration to facilitate the input translation between the PHPP and EnergyPlus.
