This is exacerbated if there are fume cupboards, as the discharges go to the roof and discharge vertically.
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.
Attenuation measures include the provision of openable windows, increased fresh air rates and avoiding air recirculation..Balancing improvements to air quality and energy efficiency..Some of the recommendations widely accepted in the industry for the re-occupation of buildings post-pandemic have a direct impact on energy efficiency.
In order to improve indoor air quality and reduce the likelihood of pathogens, fresh air rates need to be increased and air filters should be installed.However, that increases energy consumption from fans.
In naturally ventilated buildings, the recommendation is that windows should be opened frequently, even during winter, but this causes substantial heat loss and the inefficient operation of heating and cooling systems.
It is also advised that in the event of further virus outbreaks, heat recovery devices are switched off – affecting the efficiency of HVAC systems.. Additionally, the recommendation to switch off recirculating cooling systems (fan coils and passive chilled beams) to limit the movement of airborne particles would affect thermal comfort and wellbeing due to overheating..(traditional and alternative structures).
, but rather the choices we make upfront relating to the design, manufacture and assembly process..There isn’t a hierarchy with any of this, she says, mentioning the term ‘modular’ construction.
Each industrialised construction technique is just another tool in the toolkit, with varying degrees of suitability depending on the particular scenario.. She also raises the point that some people feel threatened by the industrialised construction terminology, as a result of not having the necessary skill set.As a result, they become very opposed.
