Onyx Solar has participated in a historical building’s retrofit located in the center of Bordeaux for the building supervising organization of the city, the Bordeaux Métropole Aménagement (BMA). The project – along Garonne River and close to the port – has been designed by Jean Louis Montagnier and will be a business center for some of the corporations operating in Bordeaux.
Above its five floors has been placed a skylight which combines glasses with different colour gradation and various transparency degrees, supplied by Onyx Solar. They were customized to fit perfectly in the sustainable design of the building.
INSTALLED IN BÉJAR, IT GENERATES 8,763 KWH PER YEAR AND AVOIDS THE EMISSION OF 5.9 TONS OF CO2 PER YEAR
This photovoltaic skylight represents a multifunctional solution by generating free electricity from the Sun on-site and adding bioclimatic properties to the building; in this way, it allows day-lighting, it filters harmful UV and IR radiation and it provides thermal inner comfort. The avoidance of premature ageing of materials will extend its lifespan.
This 2,900 SqF PV transparent skylight combines three different types of a-Si , see-through IG Unit. A total of 110 units provide 6,750 Wp installed.
Self-consumption has been the energy management business model selected for the project, so part of the energy generated feeds the building straight away, and the remaining part is stored in batteries to feed exterior outlets.
Ventilated Photovoltaic Skylight for a City Hall in Spain
The work for the installation of a ventilated photovoltaic skylight at Alzira’s City Hall, in Valencia, are about to finish. It’s an skylight with perimetral ventilation of the interior yard being covered.
A total of 48 semi-transparent modules have been necessary for an area of 115 m2. It’s a triple laminated glass without air chamber, that allows the trespassing of 10% of the daylight facilitating natural illumination and repelling UV and infrared rays; thus improving inner comfort.
The total installed power is 5kWp and it will generate more than 6.000 kWh a year, avoiding the emission to the atmosphere of more than five tons of CO2.
One of the main goals of the European Union is to reduce the amount of CO2 emissions to the environment and to stimulate the design of more energy efficient buildings. In order to achieve that some objectives have been established for the upcoming years, and companies, institutions and individuals showing this same commitment are being awarded.
Among those recognized actors is Onyx Solar, selected as an official partner of the Sustainable Energy Europe Campaign for its photovoltaic skylight in the San Anton Market (Madrid). The project avoid the emission of 5 tons of CO2 a year by integrating a PV glass into the roof, adding a 20% degree of semi transparency to the glass in order to permit daylight to get into the building.
The program’s goal is to showcase activities dedicated to energy efficiency and renewable energy solutions. Concretely the focus is on spreading best practice in sustainable energy technology, build alliances and inspire new energy ideas and actions.
With this award, the photovoltaic skylight will be promoted in 450 events through the year 2011, including the “Energy Days” held each year in Brussels gathering the most renowned professionals within the sector worldwide. In addition to that, the project will be nominated for the Sustainable Energy Europe Awards Competition 2011.
