It soon became apparent that systems developed for the MOJ (whose estate includes education, healthcare, offices, sports halls and workshops) would also be appropriate for the wider public sector..

The external heat rejection unit size is typically based on the required heat rejection capacity and approach temperature (external air inlet temperature vs CHW/air outlet temperature).Generally, the heat rejection plant is located as close to the data halls as possible, however, where there is a drive towards higher density data centres the typical space for external heat rejection may be limited.

To achieve an increased heat rejection capacity in limited space, the approach temperature of the unit may have increase (leading to an increase in the mechanical cooling hours annually).. Based on previous Bryden Wood data centre projects, we have plotted heat rejection plant properties based on their heat rejection capacity (kW/m.vs approach temperature(K)..Note: The footprint shown are for the unit only and exclude any access/air intake space.

For plant which are part of chilled water systems, the ancillary equipment is not included in the footprint such as pumps, heat exchangers and pressurisation system..Some strong correlations can be observed:.

Cooling towers offer.

a much lower approach temperature compared to dry air coolers (similar kW/m.We realised that the manufacturing component of the construction process could be taught to serving prisoners, helping to train them in marketable skills for use on release, and aiding rehabilitation.

We also realised that the sort of P-DfMA systems we were designing for the MOJ could then be transferred across to other government infrastructure projects, thereby facilitating the wider adoption of these beneficial, lean construction processes.. Bryden Wood published the first book on platform design in 2017 (.new updated edition of Platforms book available to download here. )

and we have continued to expand on and optimise Platforms and other MMC methodologies in our work with both public and private sector clients.We’ve never sought to patent our work and we have open sourced the code for both of our construction design apps - SEISMIC and PRISM.
