As a major sector contributing to the UK’s greenhouse gas (GHG) emissions, housing is an important focus of government policies mitigate climate change. Current policy promotes application variety energy efficiency measures diverse building stock, which will likely lead wide range unintended consequences. We have undertaken scoping review identifying more than 100 consequences impacting fabric, population health and environment, thus highlighting urgent need for society reconsider its...
Objective To assess potential public health impacts of changes to indoor air quality and temperature due energy efficiency retrofits in English dwellings meet 2030 carbon reduction targets. Design Health impact modelling study. Setting England. Participants household population. Intervention Three retrofit scenarios were modelled: (1) fabric ventilation installed assuming building regulations are met; (2) as with scenario but additional for homes at risk poor ventilation; (3) no illustrate...
With modern populations in developed countries spending approximately 90% of their time indoors, and with carbon dioxide (CO2) concentrations inside being able to accumulate much greater than outdoors, it is important identify the health effects associated exposure low-level CO2 (<5000 ppm) typically seen indoor environments buildings (non-industrial environments). Although other reviews have summarised on health, none considered individual study designs investigations factored that into...
Deprived communities in many cities are exposed to higher levels of outdoor air pollution, and there is increasing evidence similar disparities for indoor pollution exposure. There a need understand the drivers this exposure disparity order develop effective interventions aimed at improving population health reducing inequities. With focus on London, UK, paper assembles examine why PM<sub>2.5</sub>, NO<sub>x</sub> CO may disproportionately impact low-income groups. In particular, five...
A number of studies have estimated population exposure to PM2.5 by examining modeled or measured outdoor levels. However, few taken into account the mediating effects building characteristics on ingress from sources and its impact in indoor domestic environment. This study describes how simulation can be used determine concentration outdoor-sourced pollution for different housing typologies results mapped using stock models Geographical Information Systems software demonstrate modifying...
The UK government has an ambitious goal to reduce carbon emissions from the housing stock through energy efficiency improvements. This single policy is a strong driver for change in system, but comes with positive and negative "unintended consequences" across broad range of outcomes health, equity environmental sustainability. resulting policies are also already experiencing under-performance failure consider as complex system. research aimed move considering disparate objectives isolation...
Innovations in materials, construction techniques and technologies building refurbishment aim to reduce carbon emissions produce low-energy buildings. However, in-use performance consistently misses design specifications, particularly those of operational energy use indoor environmental quality. This gap risks reducing design, technology, sustainability, economic, health well-being benefits. In this paper, we compare settings the Chinese UK buildings sectors relate their historical context,...
Monitoring and modelling studies of the indoor environment indicate that there are often discrepancies between simulation results measurements. The availability large monitoring datasets domestic buildings allows for more rigorous validation performance building models derived from limited information, backed by statistical significance tests goodness-of-fit metrics. These also offer opportunity to test assumptions. This paper investigates housing using EnergyPlus software predict maximum...
There is a policy-driven focus, at present, on improving the energy performance of buildings. However, energy-related issues alone do not capture full impact buildings occupants and wider environment. The building also includes occupant wellbeing indoor environmental quality. Specifically, in schools, quality (thermal comfort, air quality, lighting acoustics) an important aspect. Additionally, issue ‘performance gap’, generally focused energy, affects parameters needs to be addressed...
Indoor temperature and air quality in dwellings are closely coupled. Differences between the indoor outside adjoining zones can influence airflow due to stack effect, whilst changes ventilation cause pollution temperature. This paper demonstrates relationship an pollutant, PM 2.5 , UK domestic building archetypes using dynamic thermal contaminant modelling capabilities of EnergyPlus 8.0 under various Climate Projections 2009 (UKCP09) scenarios (current, current ‘hot’, 2050 High Emissions...
Estimates of population air pollution exposure typically rely on the outdoor component only, and rarely account for populations spending majority their time indoors. Housing is an important modifier due to infiltrating indoors, removal indoor-sourced through active or passive ventilation. Here, we describe application indoor modelling tool a spatially distributed housing stock model England Wales, developed from Energy Performance Certificate (EPC) data containing information approximately...
Hospitals are controlled yet complex ecosystems which provide a therapeutic environment that promotes healing, wellbeing and work efficiency for patients staff. As these buildings accommodate the sick vulnerable, occupant good indoor environmental quality (IEQ) deals with air (IAQ), thermal comfort, lighting acoustics important objectives. specialist nature of hospital function demands highly environments, this makes them energy intensive due to varying specifications their functions...
The indoor air quality (IAQ) of five low-energy London apartments has been assessed through the measurement 16 key pollutants, using continuous and diffusive methods across heating non-heating seasons. This case study approach aimed to assess presence pollutants within better understand role ventilation seasonal variations in quality. results indicate strong variations, driven by increased natural rates over summer monitoring period. A combined metric for outdoor ( I tot ) suggests that IAQ...
The importance of reducing adventitious infiltration in order to save energy is highlighted by the relevant building standards many countries. This operational often inferred via measurement air leakage rate at a pressure differential 50 Pascals. Some codes, such as UK's Standard Assessment Procedure, assume simple relationship between and mean during heating season, so-called leakage-infiltration ratio, which scaled account for physical environmental properties dwelling. scaling does not...
