The second important aspect to consider is value itself.
Laboratory air-changes will be many times higher than those found in an office.This is driven by the regulations, pressure cascades, cooling loads, dispersion rates, local extraction, higher levels of filtration, and ideally some degree of futureproofing.
For Containment Level 3 (or BSL3) and above or cleanrooms, air-changes will increase further still, often becoming impractical for an office conversion.In addition, it may be necessary to separate lab HVAC systems from other parts of the building..The top priority should be to optimise the HVAC design with a view to reducing the amount of plant and riser space required.
Techniques such as transferring extract air from adjacent office spaces to partially make-up the new lab supply can sometimes be used, however their compliance must be carefully reviewed..Even with an optimised design it is likely that new, larger HVAC plant and additional ductwork will be required.
For some office buildings this can be difficult to incorporate, with limited roof, external, riser, and ceiling void space available.
Ideally, new riser space can be formed in such a way that it doesn’t significantly reduce net usable lab space or cause issues with adjacent tenancies (where relevant).In the case of Spain or Sweden, even though these materials can be shipped by boat (lower carbon emissions per nautical kilometre), the distances are so large that they amount to more than double the emissions from road only transportation.
However, they are still small compared to A1-A3.. Accounting for biogenic carbon capture when carrying out a whole life carbon assessment.Biogenic carbon capture is the process whereby trees absorb and store carbon dioxide during growth.
Once cut down, part of this carbon (from leaves, roots, and small branches) is released and the remaining is stored in the trunk, which is used for timber.. New trees are planted in its place to ensure a constant process of removing carbon dioxide from the atmosphere.As trees age, they absorb less carbon dioxide, so it’s beneficial to replace them.
