Cement is the source of approx. 8%

of the world’s CO2 emissions

Concrete is the most widely used man-made material in existence. It is second only to water as the most-consumed resource on the planet

Eliminating cement from the design and replacing it with lime will reduce carbon emissions from the creation process by 20%. Lime also absorbs CO2 within its drying and hardening process. Some of this lime can then further be replaced with recycled fly ash this will reduce further. Plastic aggregates that are common by-products of many industrial processes allows for a replacement of sand.

Currently 50million tonnes of excess fly ash in landfill sites being managed as a waste material, with the remaining Coal-Fired Power Stations planned for complete closure by 2025

Using existing industries that create fine plastic waste as a by product of manufacture that would otherwise go to landfill as well as those materials already sitting on landfill sites

Utilising the soil conditions within the boundaries of where Nu Living are able to build, Lime Stabilised Soil Columns allow for a method of piling that replaces a large amount of concrete with the already existing soil on site and a mixture of quicklime, otherwise known as Calcium Oxide.

Using a relatively small mobile rig, The Auger is drilled down into the soil to a depth that corresponds to the prescribed column length. Powdered quicklime (CaO) is forced into the soil with compressed air through a hole located just below the horizontal blade of the auger, and the lime is mixed thoroughly with the soil.

A Pre cast Lime & Fly Ash concrete ring Beam allows for a greater reduction in Carbon dioxide, the use of waste materials Like Pulverised Fly Ash and Polyethylene terephthalate and precise tolerances for Mass timber to be attached to. This Plug-in looks to maximise the use of factory built and ready modules in both new mixed use residential developments and renovations by Nu-living, aiming to further improve the sustainability of the Nu-Build system. It creates opportunities to easily integrate a post and beam mass timber system into Nu-Build Modular system, to create more adaptable and open space for a range of uses, whilst eliminating the need for a concrete/steel frame ground floor within the system.

With a maximum Story Height of the Nu Living developments on top of the Piles will be 5 storeys due to load bearing tolerances.
