Hi to everyone who attended this morning's excellent seminar on the theme of collaboration and thank you for all the lovely emails and LinkedIn messages. I am so pleased it has resonated!
I mentioned the calculator I developed and the thinking around expressing ROI tailored to the different stakeholders: investor, owner-occupier, landlord, tenant etc in order to push through the often incorrect cost assumptions.
Here's the chapter I wrote for 'Creating the Productive Workplace' (Routledge, 2017) edited by Professor Derek Clements Croome. This version is about workplaces but the theory, which I started to develop in 2008, translates to housing, education and healthcare buildings with adjustment of the headings in the metrics. I have used it with the NHS and with a major insurance company and in both instances it created the unequivocal financial case to retrofit or replace buildings because decision makers could look beyond capex and opex into quantifying a whole range of major criteria that are rarely considered. This isn't just about traditional whole life costing and embodied carbon etc, it's about human and societal impacts. This can be overlaid with WLC data for a complete picture ... but this element is rarely incorporated and hence results in very poor or short-term decision-making.
With housing the model can look at the cost to the NHS of poor physical and mental health caused by bad housing; social costs with consequential impacts of unemployment or low employment (causal and resultant links with housing) plus poorer educational outcomes for children in sub-standard housing; crime ... the list goes on but there are many sources of evidence that housing has a direct link with good society.
I would be pleased to extend the theory into housing to create a white paper to drive the need to change government policy around affordable/social housing and the case for scaled-up retrofit for net gains across the board, if we were to get the holistic, collaborative approach that everyone in the sector knows we need!
