SITE:  The masterplan incorporates a robust renewable / sustainable energy strategy, including low energy cooling measures, green roofs and over 0.8 hectares of public space.
Six towers – 24 storeys above the courtyard blocks

CONCRETE SLAB:  (image 1, 2) horizontal slabs of steel reinforced concrete (typically between 100 and 500 millimeters thick- most often used to construct floors and ceilings, while thinner slabs are also used for exterior paving)

-ground-bearing or suspended slabs
-pre-cast concrete slabs or in situ

In situ concrete slabs are built on the building site using formwork – a type of boxing into which the wet concrete is poured. Reinforced slab: the rebars are positioned within the formwork before the concrete is poured in. Plastic tipped metal, or plastic bar chairs are used to hold the rebar away from the bottom and sides of the form-work, so that when the concrete sets it completely envelops the reinforcement.
Suspended slab: the form-work is shaped like a tray, often supported by a temporary scaffold until the concrete sets.

Formwork: built from wooden planks and boards (plastic, or steel).

Two main thermal considerations:
1. insulating a floor slab.
Concrete slabs are usually cast above a layer of insulation such as expanded polystyrene, and the slab may contain underfloor heating pipes. However, there are still uses for an uninsulated slab, typically in outbuildings which are not heated or cooled to room temperature. In those cases, casting the slab directly onto a rocky substrate will maintain the slab at or near the temperature of the substrate throughout the year, and can prevent both freezing and overheating.

2. high thermal mass:  applies to walls and floors, or wherever the concrete is used within the thermal envelope. Concrete takes time to warm up, which causes a delay in warming the building. But it is an advantage in climates with large daily temperature swings, where the slab acts as a regulator, keeping the building cool by day and warm by night.

The site is still in its demolition stage, so the analysis applies to the demolished building components of the previous building – The Karen House on Brunswick Place.

– Brick load bearing wall panel, spans between two other load bearing wall panels. 300 mm thick, circa 2m high and 5m wide with the maximum weight of 5 tonnes.

– Lime-and-sand bricks – C73-10 – crushed quicklime mixed 5-10% with sand and water ( 1:12 ratio of lime to sand) – left to dry for 12 hours – compressed into moulds – the usual shape 9 inches long by 4,6 inches by 2,5 inches at the pressure of 2 tons per square inch, equivalent to about 90 tons on each brick. They are then run into a long steel boiler, where the steam is blown in for four hours at 165 lbs. pressure per square inch at a temperature of about 370 degrees Fahrenheit. Sand-lime has a primary energy content of 190,6 kWh/t. The bricks are stacked together in situ with mortar and can be coated to improve both the insulation as well as the image of the facade.

Architect – Zaha Hadid Architects
Engineer – Buro Happold, Max Fordham Consulting Engineers
Contractor – Empty, S.L.

Building Component – GRC / Fibre Reinforced Concrete

Material Properties
The exterior made of GRC / Fibre Reinforced Concrete had been pre-fabricated in moulds to be assembled and constructed on-site, spanning 2.20m in height. Fibre Reinforced Concrete allows for a simple yet cold expression for the façade, the façade itself made of 2 x 4m panels weighing 800kg each. This material, 6cm thick is made by two waffled concrete layers sandwiching a honeycomb mesh that allows for stretching in various directions, making it a robust composite material.
