industrialised construction.

The heat rejection plant can be positioned on the roof or even remotely from the data hall itself, providing valuable design freedom..External heat rejection options:.

Chilled water systems are compatible with a range of external heat rejection options, including dry cooling, dry cooling with partial evaporative assist, and full adiabatic cooling.This allows for optimisation based on climate and environmental considerations.. A key factor in maximising the heat rejection system (with chilled water) efficiency is minimising the heat rejection unit approach temperature i.e.the difference between the external air temperature and the chilled water outlet temperature.

Every degree closer results in mechanical cooling being eliminated for potentially hundreds of hours, leading to significant energy savings.In hot, dry climates, using adiabatic cooling which cools towards the wet bulb temperature which is often much lower than the dry bulb temperature, can further reduce the number of hours of mechanical cooling required.

The balance between reducing energy / water consumption as part of the design is investigated as part of each project design.. Water usage.

A growing challenge for data centre providers is water availability.PMV is calculated as the percentage of cost that is derived before any site works and strongly encourages maximising the proportion of off-site works.. As a result, many parts of the construction industry are focusing more and more on off-site prefabrication in pursuit of benefits including lower cost, reduced delivery timescales, higher quality, improved health and safety, less waste and more productive site labour..

But is off-site always the best way to achieve these benefits?Construction sites have been around since the dawn of civilisation.

Do we really want to walk away from all that learning, and start moving as much of the construction process as possible into distant sheds?.Is on-site construction really all that bad?.
