How to Use a Karcher Window Vacuum for Best Results

Modern Methods of Construction (MMC) is a new, exciting market in Australia..

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).

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.This categorisation is quite diverse and includes a range of pre-manufactured and pre-assembled systems but also non-system components, site-based material innovations and process innovations..

There is no fixed list of MMC methods in each category.There is great scope for the construction industry to innovate and develop new MMC methods to expand the toolkit and enhance the DfMA designer’s ability to achieve benefits on future construction projects..

Under the MHCLG categorisation, volumetric modular construction (known in Singapore as Prefabricated Prefinished Volumetric Construction or PPVC and in Hong Kong as Modular Integrated Construction or MiC) is an example of a 3D primary structural system..In addition to volumetric solutions, many other different MMC methods including flat-pack and componentised systems are primarily prefabricated and are often grouped under the umbrella term “Offsite”..
