Client:  Internet Service Provider

Requirement: Data Hall Cooling Walls

Overview: The client has built six data halls within a secure premises. Each data hall was required to have floor to ceiling louvred walls which run the entire length of the rooms. In total over 600 m2 of ventilation louvre walls.

The solution: Aluminium Systems Ltd installed heavy duty box sections to create a framework of vertical and horizontal supports. Each framework standing over 5 metres high and with widths of up to 40 metres, fixed to heavy duty steel uprights, and bolted to the floor. This framework formed the basis of each of the systems, which consisted of vertical mullions carrying 30 x 145 mm wide elliptical blades at 100 mm centres.

The challenges: Three of six data halls were on the ground floor, with remaining three immediately above them. The louvre blades were each supplied at a length of 7.5 metres and then trimmed to exact size in situ. This meant that a total of 900 blades were supplied to site, of which 450 had to be brought up to the first floor by telehandler and then manoeuvred by hand into position. The supply, delivery and safe storage of the blades required careful logistical management and clear and accurate communications between the site management, the installation team and the delivery company.

Each of the data halls required a carefully planned timetable of events to ensure that the delivery and installation of the framework, louvre blades and flashings occurred at the correct point in the overall project timeline. Working closely with other trades, such as flooring and ceiling fitters, electricians and air conditioning engineers, our fabrication, delivery and installation teams were able to ensure “just in time” delivery and fitting.

The project was delivered on time and within budget.

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.

Vertically Mounted Screening Blades

In this configuration, the louvre blades are stood “on end” and built into a frame which stands off a little way from the building (this allows for access to the glass for cleaning). This type of shading is often used when an architectural feature is required to shade a floor to ceiling window, it is generally offered as a fixed blade solution. However a motorised version of this system has been successfully deployed across a number of branches of a high street bank in Ghana

Motorised Brise Soleil

Motorised Brise Soleil - when should motorised BS be considered?

For many applications, a fixed blade system provides all of the functionality required by the client. For example, if the system is being used primarily as privacy screening, or as an architectural feature, then a fixed blade system is almost always the preferred solution. Even when solar shading is the primary objective, this can still very often be achieved by the use of a fixed blade system. With lower costs, simplified installation and no moving parts, a fixed blade system offers most customers the best balance of functionality against price and ease of use.

There are however circumstances when an adjustable blade system provides more consistent solar shading across the whole of the day, and throughout the year. If such a system is required, then the blades are mounted on pivot points at each end, joined together with a connecting rod, and moved by means of an electric actuator (a motor that moves the connecting rod backwards and forwards). The amount of movement and the direction of rotation are usually controlled by a hand held wireless controller, rather like a TV remote control. However, if required a third party automated system, such as a BMS (building management system) can be linked in to control the motor automatically.

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.
