Case Study: Customer description: High Street Bank in Ghana

Requirement: Motorised upright louvre blades and fixed blade Brise Soleil

Overview: The client wished to have a combination of motorised adjustable window louvres, a fixed blade shading canopy and a fixed blade roof screen

Solution: Aluminium Systems designed the various elements of the systems, using a combination of 200 mm and 145 mm wide elliptical blades.
The 200 mm wide blades were attached to top and bottom frames, set within the window reveals, which housed the actuators and connectors for the adjustable window louvre blinds. The 145 mm wide blades were used for the fixed blade elements of the system, and were attached to the building using standard vertical and horizontal mullions with bird beak blade supports built in to them.

The challenges: The initial trial systems supplied were for five bank branches, which involved five horizontal canopy systems, five vertical screen systems and a total of 35 motorised systems. These were all fabricated in the UK, dismantled and packed in kit form for shipping to Ghana. The kits included all of the powder coated aluminium elements, the electric motors, the connecting systems, the wiring harnesses and remote wireless controllers. 

All of the kits were colour coded and labelled for ease of identification once on site. Each branch kit had a comprehensive parts list and full installation and test instructions. The first branch, which was in the city of Kumasi, was installed under supervision by Aluminium Systems staff. Subsequent braches were installed by local installation teams. 

This is part of an ongoing rebranding project that the bank expects to roll out to all its’ other branches across Ghana over time. 

Sun-Tracking Photo Voltaic Louvres

Motorised Sun-Tracking Photo Voltaic Louvres

This product is specifically designed to perform two jobs. Firstly to offer solar shading throughout the day to glazing mounted underneath the system, and secondly to generate power by means of photovoltaic cells built into the louvre blades. The louvre blades are created from aluminium frame profiles which hold solar panels which are made up from the photovoltaic cells.

As the sun passes overhead from east to west during the course of the day, the on board sun tracking computer controls an electric actuator which moves the louvre blades so that they are allows facing the sun. This offers maximum shading to the glass below, and also ensures maximum power is generated by the p v cells.

The power is transmitted from the cells via in built cables to the pivot of the louvre blade, which is hollowed out to allow the cable to pass through it and out to the DC to AC invertor array. From here the AC voltage is distributed into the mains supply. At sunset the tracking computer commands the system to reset all of the louvre blades back to the starting position, ready for the next sunrise.

Vertically Mounted Ladder Screening

Vertically mounted systems offer a high degree of solar shading in certain circumstances, but can also offer security and privacy functionality. Although generally offered as a fixed blade system, vertically mounted ladder systems lend themselves quite well to being motorised, offering a more comprehensive level of screening, and allowing the customer to adjust the blade angle.

Vertically mounted ladder systems are quite often used to shade runs of curtain wall, particularly in commercial buildings that have large areas of glazing such as car showrooms, office blocks or in schools. The blade size, pitch and angle will determine the amount of shading in any given situation.

Fixing this type of system to a run of curtain wall needs to be planned well in advance, as the mounting brackets have to be incorporated into the curtain wall mullions before they are installed. 

Continuous Plant Room Louvre Walls

As the name suggests, this is the method by which walls can be created from a combination of rows of vertical mullions with louvre blades clipped to them. Common uses of continuous louvre walls include creating plant rooms and creating visual screens on the upper levels of buildings. Continuous louvre walls are generally fabricated from the larger pitch louvre blades, typically 75 mm or 100 mm.

Continuous louvre walls often incorporate louvre doors as part of the system. Latest generation louvre walls use elliptical louvre blades rather than the more traditional “Z” profile blade. Typically available in 60 mm, 120 mm, 145 mm and 200 mm blade widths, and designed to maximise the throughput of air from one side of the wall to the other, these systems offer a typical free area of between 40% and 50%, making them viable, cost effective alternatives to “Z” blade systems.
