In the first place, DfMA is often used to mean prefab, which it doesn’t.
But can we have both?.The Chartered Institution of Building Services Engineers (CIBSE) has just released a. set of documents.
which provide guidance for building owners and managers on how to start reoccupying their buildings.The guidance relates to safe working practices and the assessment of building services..Some of the key themes are around air: providing more fresh air and avoiding recirculating air.
The guidance includes bypassing those heat recovery devices which may recirculate air in some circumstances, and considering air pathways – how air comes in, moves around and leaves a building.This is because occupants of a poorly ventilated room are exposed to a higher concentration of airborne pathogens.
The risk of exposure increases with the time spent in such an environment..
Suddenly, wellbeing and temperature control are higher on the priority list than energy efficiency and the climate emergency.. More fresh air, and its impact on energy efficiency.Most components use no or low levels of fabrication (these can be thought of as ‘dumb’ components).
These components tend to be the large, heavy, commoditised elements including:.Columns - standard square hollow sections are used with little/no ‘fabrication’ (a single hole is punched or laser cut in each column);.
Beams are made using a standard rolled metal profile (metal coils are passed through a highly efficient, automated rolling process with virtually no waste, no double handling etc.)as a permanent shutter for concrete.
