%X 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.
