It brings together the conclusions of three books and the findings of multiple research papers undertaken by the author and published by medical, engineering and social policy journals. This work aims to highlight the links and connections between the diverse arenas of urban form, building design, energy efficiency, indoor air quality, respiratory medicine and immunology, all within the socio-economic framework of a small damp country on the fringe of northern Europe. Keywords: indoor air quality; asthma; public health; housing; energy efficiency; timber frame construction; urban planning; asbestos; feudalism; mould fungal spores; vapour barriers 1. Introduction Life expectancy in many Scottish cities and regions has lagged behind the rest of the UK. The average life expectancy of a male living in the Calton area of Glasgow is 53.8 years [1]. Although mortality remains an excellent measure of poverty, “big data” statistics on morbidity may be a better measure of overall quality of life in any particular country or region. Scotland has for instance, the highest rate of cancer, heart attacks and respiratory disease of all countries in the EU [2]. In addition to genetics, there are 16 major determinants of public health in any given society organised on the basis of neo-liberal economics. These can be categorised under four generic headings (see Table 1). Table 1. 16 determinants affecting Public Health. Socio-Economic Environmental Lifestyle Access to Services Employment Air quality Exercise Education Social inclusion Housing quality Substance abuse Health services Social capital Water and drainage Diet Leisure facilities Safety net Urban form Risky behaviour Transport Although “lifestyle” is seen as being the dominant factor under individual control when public health is being discussed, we should not underestimate the role of the environment. The additive, synergistic and antagonistic combinations produced by the quality of our homes, workplaces and cities, and the access they provide to a range of services (cultural/medical/educational), are crucial components, and can influence both life expectancy and any given population’s overall wellbeing. The post-war history of Scotland provides many valuable lessons on the deleterious effect on public health that can occur when policy makers, in concert with architects and planners (even when operating with good intentions and noble motives) adopt “Corbusien” modernism as the optimum Sustainability 2018, 10, 18; doi:10.3390/su10010018 www.mdpi.com/journal/sustainability Sustainability 2018, 10, 18 2 of 19 replacementSustainability strategy 2018, 10, 18 for slum clearance.
