This method also facilitates rapid assembly and cost-effective scalability.. Decarbonisation and sustainability.
Chilled water systems can accommodate various data hall layouts and are suitable for future integration of liquid cooling technologies.. Heat rejection plant location:.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.Carbon reduction against baseline.
The path to a sustainable future.. With the growing interest in net zero buildings and sustainable construction, Bryden Wood have developed and implemented their own hierarchy to reduce both operational and embodied carbon.These hierarchies define the roadmap to achieve good and best practice performance targets defined by bodies such as LETI, RIBA or GLA.
An essential part of the hierarchy, and one of the key focuses of Bryden Wood’s design approach is DfMA, which enables substantial embodied carbon reduction and creates synergies to further reduce operational carbon.The implementation of DfMA combined with energy efficiency measures, specification of low carbon materials and carbon offset measures is the proposed pathway to the delivery of successful net zero carbon buildings..
