Together, the development of these captures the purpose and evolves the understanding of requirements.
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.Normally, having fewer people in a building would allow ventilation rates to be reduced, making a building more energy efficient.
However, in order to reduce the risk of viral spread within the building we have to increase ventilation rates as far as practically possible, so that the occupants have more fresh air.. A higher ventilation rate, whether it is via natural or mechanical ventilation, will result in an increased demand on heating in cooler weather, and increased demand on cooling in warmer weather.
This may be exacerbated in a mechanical ventilation system where we’ve had to disable the heat recovery device.Accuracy in installation is achieved via factory conditions on site:.
Standardised platforms and components.Increased use of standardised, repeatable, design and components inherently lead to less variance and more standardised tasks on site, which already reduces the risk of the need for changes and thus the potential to deviate from the original design..
The greater use of consistent, digital workflows through design, procurement and manufacturing will extend into of logistics and labour; predicting operative numbers, positioning them on site and schedule their training and workload.This level of control is unremarkable in manufacturing, extraordinary in construction.. 2.
