Design
Both systems are adapted to the shape of the pergolas that adorn the square. The systems were designed in such a way that they would go unnoticed at first glance, being embedded in the aesthetics of the pergolas.
The spraying system was installed at a height of three metres and following the shapes of the pergolas. At this height it is possible to reach a larger area, but allowing the effect to be felt at ground level.
The design of the curtain is made according to the requirements of the projection of the curtain on the square. With a length of nine metres and a height of four and a half metres to project over water and four points of support, the rest of the installation and systems were designed to meet these needs.
Execution
The installation of the water curtain and spraying system was completed within two months and included:
- Installation of hydraulic components
The necessary pipes were installed for the supply, connection, emptying, overflow and cable routing of the curtain and the spraying system. These pipes were buried and prepared under the ground, which was then backfilled and prepared for the assembly and installation of the systems in the pergola.
The pipes were also prepared for the passage of cables so that the work on the square could continue.
- Placement of equipment on pergolas:
A perfect synchronisation between the installation of the pergolas and the systems was necessary as they were highly interconnected. The lighting systems, supply and spray pipes, distribution manifolds, nozzles and lighting systems were installed on the pergola.
In the centre of the curtain, three metres away, the projector and its cooling system were installed, which guarantees a longer service life due to the extreme temperatures in Zaragoza.
At the ends of the curtain, in order to amplify the sound further, the loudspeakers are installed as pendant speakers.
- Electrical installation:
Upon completion of the installation of the equipment in the technical room and pergolas, all the necessary equipment was connected for the proper functioning and perfect synchronisation of the sound, projection, water fall and lighting systems of the curtain and the spraying system. The installed control system offers the possibility of remote control.
The hours of operation and the effects to be included in the video projection were programmed according to the requirements of the city council.
Sustainability
At OTB, we take European sustainability criteria into account in the implementation of our projects. We use products from the city, such as loudspeakers from a local company, to reduce the environmental impact of transport.
In terms of energy efficiency, we design our facilities to be highly efficient. A low-power LED strip was installed in the curtain to reduce power consumption without compromising performance.
In addition, the water curtain works with water in a closed circuit, which allows us to reduce water consumption. Water is only provided sporadically when necessary, which contributes to the conservation of this vital resource.
In short, at OTB we strive to incorporate sustainability principles into our projects. We use local materials to reduce the environmental impact of transport, prioritise energy efficiency through the use of low-power lighting technologies and adjust our facilities to minimise water consumption. These measures demonstrate our commitment to sustainability and environmental protection.
