BREEAM ES Excellent
LEED 2009 BD+C (New Construction) Gold
The Orona Zero building is the flagship building of the Orona Ideo – innovation city, a campus composed by various buildings that merge business, research and university, developed by the Orona lift manufacturing company. The building houses the corporate headquarters of the company and its form is inspired by the circle, a constant shape in the company’s brand image.
The design of the building seeks to evoque elegance, dinamism and elevation through an abstract formal gesture: a hollow cylinder of 90m in diameter, 16m in height and a 15º incline. It rises from the ground to create a 1.500m2 overhang at the entrance from the city and sinks on the opposite side, allowing passage through and generating a roof-façade for capturing solar energy.
The interior of the building recreates different working environments from desks and closed meeting rooms to a series of lounge spaces suitable for informal meetings and personal work. These designs have the ability to imprint a special character to the working spaces and also seek to evolve the brand culture of the company among the employees.
Orona Ideo is the first building complex in Europe to simultaneously obtain both LEED Gold and BREEAM Excellent categories of certifications. It is important to underline that Orona Zero has been awarded the First Extraordinary Point for Innovation ever awarded by BREEAM ES. This point of innovation has been achieved in the field of energy efficiency and more specifically the requirement ENE 8 related to Lifts.

The architectural design is particularly sensitive to bioclimatic issues and has shaped most of the architectural solutions. Orona Zero is mainly devoted to office spaces, which have large internal energy loads due to its occupants and to the density of the electronic equipment which dissipates heat and, at the same time, requires diffused light to avoid glare. The ground plan places the workplace near the outer façade which is mainly north facing, whereas the south-facing ring-shaped gallery distributes the flow of people and overlooks the building’s central void. This is a space of a more social nature where sun capture is welcome and does not interfere with the work space. The service ring with stairs, lifts, toilets, utility shafts, etc. acts as a buffer between the two areas and structures the depth of the bay, creating different spatial situations due to the building’s inclined geometry.
The curved façade is made up of a skin composed of more than 2,000 triangular pixels which change by means of a parametric design from: opaque, translucent and transparent, depending on their orientation, the incident to solar radiation, the access to external views and the privacy of the rooms. More than 1,000 polycrystalline photovoltaic modules are integrated on the inclined rooftop of the Orona Zero building that will have an annual electricity output similar to the electricity consumption of 100 average flats.
Orona Zero is a NZEB with low energy demand, low consumption and zero carbon emissions. This has been made possible thanks to its bioclimatic design, its photovoltaic roof and the District Heating-cooling. This system is powered on 100% renewable energy sources: geothermal, thermal solar and biomass. The water that is heated or cooled using the District Heating-Cooling system is distributed to the substations located in each of the buildings, and, at these points, the flow of energy is adapted to the different conditioning systems.
Orona Zero has been benchmarked by the World Green Building Council in its recent report on Health, Wellbeing & Productivity in Offices.
