Abstract

SUMMARY: Monitoring and modelling studies indicate that UK housing stock may significantly modify exposure risks to indoor air pollution and overheating due to inter-dwelling variation in fabric energy efficiency, airtightness, and a reliance on natural ventilation. We describe the development and initial application of a new model of indoor air pollution from outdoor sources and overheating for the English housing stock using a metamodeling approach. A large number of building physics simulations were performed in EnergyPlus for representative dwelling archetypes, with values of building energy efficiency, airtightness, occupant behaviour, surrounding environment, and climate randomly sampled using information from building stock databases and future climatic projections. Based on the simulations, a Python-based Neural Network metamodel was developed that can rapidly calculate the exposure risks inside dwelling variants under various scenarios. We present model results, including estimating outdoor pollution infiltration and indoor overheating for the West Midlands region in the UK. / PRACTICAL IMPLICATIONS: This work uses a metamodel based on building physics simulations that enables the estimation of English population exposure to indoor pollution from outdoor sources and high indoor temperatures under a range of user-specified building retrofit measures, occupant behaviour, and current and future climate scenarios. It is intended to quantify the indoor health risks and benefits associated with energy-efficient refurbishment under future climates.
