Depending on the problem you're trying to address, you can set the level of the size of the Chip to the level that is appropriate to your analysis.
The impact of the pandemic and the interest in wellbeing, combined with higher pollution levels in urban areas, have increased the importance of improving indoor and outdoor air quality..In order to improve outdoor pollution, local planning policies in some areas of the UK are requesting that buildings become air quality neutral and even air quality positive.
This can be achieved via the adoption of fully electric HVAC systems that do not pollute the local environment, the use of green infrastructure and vegetation, and facilitating the use of sustainable modes of transport..It is widely reported that indoor air pollution is 3.5 times higher than outdoors.This is due to the lack of ventilation, cooking, the use of chemicals for cleaning and emissions from construction materials and furniture, which cause an increase in the density of pollutants.
The range of measures to improve indoor air quality and hygiene is quite wide.Primary prevention measures should include the selection of non-toxic materials, products with low levels of Volatile Organic Compounds (VOCs), furnishings without fire retardants and cleaning products without harmful chemicals..
In areas with potentially high pollution levels, the adoption of adequate monitoring is recommended, combined with air filtration systems (HEPA filters for PM2.5 particles, carbon filters for VOCs and UV light filter for airborne pathogens)..
Measures to improve hygiene and reduce the transmission of pathogens include the adoption of touchless technology (light switches, lift buttons, doors), antiviral coatings and the provision of hand sanitiser dispensers.In essence, we need someone to take the brakes off, overcoming the friction and constraints.
COVID-19 facilitated that to a certain extent, with companies forced to transition to digital very quickly and managing to do so successfully.However, while every other sector has experienced disruption to their business model creating major changes, construction is very risk averse and the implications are long-term.
To get a digital thing slightly wrong has, in a sense, a transience that doesn’t matter.However, there are bigger implications for not building a building correctly..
