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. date: 2016-07-03 date_type: published publisher: International Society of Indoor Air Quality and Climate (ISIAQ) official_url: http://toc.proceedings.com/33709webtoc.pdf full_text_type: other language: eng verified: verified_manual elements_id: 1139387 isbn_13: 9781510836877 lyricists_name: Davies, Michael lyricists_name: Hamilton, Ian lyricists_name: Mavrogianni, Anna lyricists_name: Shrubsole, Clive lyricists_name: Symonds, Philip lyricists_name: Taylor, Jonathon lyricists_id: MDAVI86 lyricists_id: IHAMI19 lyricists_id: AMAVR49 lyricists_id: CSHRU11 lyricists_id: PSYMO82 lyricists_id: JGTAY63 actors_name: Taylor, Jonathon actors_id: JGTAY63 actors_role: owner full_text_status: restricted series: International Conference on Indoor Air Quality and Climate volume: 14 place_of_pub: Ghent, Belgium pagerange: 1157-1164 event_title: 14th International Conference on Indoor Air Quality and Climate (INDOOR AIR 2016) event_location: Ghent, Belgium event_dates: 03 July 2016 - 08 July 2016 institution: Indoor Air 2016 book_title: Proceedings of the 14th International Conference on Indoor Air Quality and Climate (INDOOR AIR 2016) citation: Taylor, JG; Symonds, P; Mavrogianni, A; Davies, M; Shrubsole, C; Hamilton, I; Chalabi, Z; Taylor, JG; Symonds, P; Mavrogianni, A; Davies, M; Shrubsole, C; Hamilton, I; Chalabi, Z; Wilkinson, P; - view fewer <#> (2016) Estimating Current and Future Indoor Air Pollution and Temperatures in England.
