The industry needs a shift in business models, moving away from return on capital employed to a focus on sustainability and innovation.
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.Data centres utilising evaporative cooling systems need a consistent water supply for process cooling and obtaining this can be increasingly difficult in some regions.
Water stress levels (calculated by UN-Water) are low for European regions but there is much higher stress in North Africa and Asia, which may lead to fewer data centres obtaining water for process cooling.. Space efficiency of heat rejection plant.
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).In short, we want factories to be less like construction sites.. Construction Platforms: our MMC approach to achieving the best mix of on-site and off-site construction.
At Bryden Wood, we have over 25 years’ experience applying all types of MMC solutions to a huge range of projects.Our industry-leading approach to MMC has developed over the years to consider ways to maximise the productivity of both off-site and on-site construction works to achieve better project outcomes for our clients.. Much of our thinking has been published on our website, particularly in our series of books about Construction Platforms, including the recently updated.
Delivery Platforms for Government Assets.The concept of a platform approach to DfMA (P-DfMA) has been adopted by the UK Government, particularly the Infrastructure and Projects Authority (IPA), who have said they will mandate construction platforms by 2023 for all social infrastructure..
